This advice may be unintentionally misleading. HDMI is fine and even desirable, but you do have to ensure that your monitor is set to expect a full range input, and your computer’s graphics card is also set to output full range. Because HDMI is also used for movies and videos on TV’s and your computer knows it’s connected via HDMI, its graphics card may be set to Limited range by default if you haven’t changed it. The HDMI cable itself has nothing to do with it… it just carries what the computer sends.
I found the same informatons in the web. I also checked my devices and everything was/is correct. Anyway I didn't know this bevore a good video.
That's absolutely correct. HDMI has nothing to do with it. You can still have displayport connected and outputing limited range from the graphics card, or the monitor is set to limited range. Many people intentionally using limited range and calibrating to limited range to conform to broadcast standards.
@@automate7300 This is actually true.
And all of this is set by default for 99% of systems which is why we don’t hear about this color difference purported by this video. It’s also automatically detected on 99% and set accordingly
How do you change the settings in an Apple M1 GPU Integrated Graphics card ?
The origin of 16-235 come from the time where we are using Cathode Ray Tube (CRT).
Clipping at 16 IRE was a trick to mask (cover) the retrace beam
Clipping at 235 IRE was a trick to avoid buzzing in the analog audio.
That limitation was useful long time ago when the image science was not digital.
There is no such thing as "limited range" in HDMI specs. HDMI always carries RGB888 data in 8b10b(TMDS) encoding.
Thanks buddy for taking time to let people know about this issue... now sit back and enjoy all the specific questions and troubleshooting that folks are going to ask you in response. I personally am going to need you to come to my house and set up my monitor for me... :D
Another thing to consider. A few years ago Linus Tech Tips bought a cable testing machine. You'd be surprised the amount of shady cables there is out there! So not only is there an issue with the input range but the cable itself might not be good. My suggestion is go for a well know brand and / or run away from cheap cables. Oh by the way that cable testing machine was a few thousand dollars so chances are you can't really test your cables.
In any case, thanks for the headsup!
This is the correct answer. When our lab got rid of BenQ monitors the majority of our display issues went away. I'll listen to this guy when they can figure out how to make their monitors with components that live beyond 60 hours.
There is literally zero within a cable that will limit a signal. It would have to purely come down to quality of material degrading the signal. Their guest is trying to claim that that is creating a defamation of the image quality. So my question is, how did the cable, if it's just a series of wires, alter the digital signal?
His description of how he tested the two cables wasn't even remotely scientific. He just swap between two different types and didn't swap between different manufacturers.
So so this whole video was a giant exercise in misinformation. But I bet he's earning some money off of it so I doubt he'll take it down after the top comment already flushed his entire video down the toilet.
Cheap vs 'popular brand' has nothing 2 do with quality U stupid robot.
@@dmn5384 "Just series of wires." My brother had problem with new monitor. It went randomly to black for few seconds and then image came back. I Googled problem, brother bought quality cable and it fixed problem. DisplayPort-cable has high frequency signal and if monitor and graphics card can't communicate clearly, then GPU will stop sending signal.
This is awesome. Thanks Glyn and Chris for the excellent tip shared.
I've been looking for info on this for years! Thank you
Awesome information Glyn and Dr. Chris thank you!
You always come with invaluable content. Thanks a bunch
Wow. I figured this for a belated April Fool and watched with a fading grin as the logic soaked in to me.
Then I went into my graphics card driver settings. And guess what I found? Yep. Limited range. I switched it to full. Long story short...
That annoying color cast I've been scratching my head over has gone. I could be psychosomatically imagining the improvement, but it's now crisp and clear in a way it never was.
I now have the full depth of shadow and highlights that I should. And for that, I will be forever grateful. I'm a convert, I saw this with my own eyes. Thank you!
Thanks for this valuable insight. Many videos on calibration, but never this insightful breakdown. Appreciated!
Great video and great advice. I actually have been using my new very high definition monitor with HDMI thinking that the trade of is not that big of a deal, until I saw this video. Great explanation and makes sense. Just ordered a display cable and can't wait to see the difference. thank you for a valuable information and details on how and why it is important to use the proper cable for colors.
Wow! Thanks for letting us know Glyn.
No worries Mark.
If you're able to dive into graphics card settings you 'may' be able to change to full range as you can with some (NVIDIA) but Mac isn't possible. Either way, USB-C doesn't need any settings changing ðŸ‘🻠Hope you're keeping well out there.
Great information!n Since getting my newest monitor I've been using Display Port or a lightning cable with my Mac but I didn't know there could be an issue with using HDMI. It would be great to hear how one would know if this would be an issue on a particular machine/monitor set up. Though I doubt I'll be going back to an HDMI in the future.
Glyn, this is a problem with all monitors and printers, thanks for sharing.
Great advice. Thank you ðŸ‘ðŸ¾
If you have an Nvidia graphics card you can change this setting in the Nvidia Control Panel under Display - Change Resolution - Output Dynamic Range, and set it to "Full"
Thank you mate ... yeah I've lesrned this from some other comments so it's grest to see this. However, I'm Mac and don't have that option with the M2 and I think for someone that doesn't know how to or is able then simply using a different cable is the best option. cheers
@@glyndewis Makes sense... either way your video prompted me to find the setting and turn it on, so thanks for the video!
​@@glyndewis mac is so "professional" for photo editing, that it does not allow to disable colir clamping in drivers.
Nvidia have had it set to limited range in their drivers since 2007 or so. I still wonder why when in most of the cases a PC is connected to a monitor and not a TV.
Full range should be default.
Tu bru great advice
Thank you Glyn...Just changed full range 0-255 on my desktop Invidia driver control.
Great
The message in this video is a good one, and I only stumbled across it out of curiosity thinking it was about a direct connection from the camera to the monitor. The title doesn't imply it is the computer to monitor connection. By specifically aiming it at photographers in the title I didn't get the computer to monitor connection at all until I watched the video.
Somehow 5+ years ago and with prior Samsung monitors, I got my current Samsung monitor to perfectly match my prints. When I recently needed a new PC I opted for my first Mac and it allowed for those monitor settings so everything is still spot on. It's a Studio Max. The current and previous are HDMI connections. When I upgrade to a 32" 4k monitor I might stay with Samsung to be sure everything stays as is. I shoot and print everything Adobe98. I calibrated by eye and no devices.
I've been using Dell premiercolour (UP-Q series) monitors for over a decade, and have always use displayport due to the limitations of legacy HDMI revisions (bandwith, resolution, colour space/bpc etc.) - So I guess I dodged this bullet too, because I've always had good quality DP cables and purchased motherboards with DP as standard when building new PC's.
Great informative video, thank you!
And as another commenter said: I too also switch to 10-bit colour (in Nvidia app) for my DP connection. Found under Display>Change Resolution> Use Nvidia Colour Settings >In the Nvidia settings app.
I guess thats great if you have an NVidia card but Apple M1 GPU Integrared Graphics card ??? 🤔
@Twisted, you’re exactly right. ATI and Nvidia both make reasonably priced “workstation†cards that have display port output. If you are serious about colour of your monitor and being able to calibrate correctly 10 bit per colour channel, display port is the only way. Thankfully Nvidia with their RTX series cards now give you the option of either gaming or studio drivers(for 10bit output) at good pricing. I’ve had a NEC PA271w wide gamut monitor for years and now a 4K Dell studio monitor with built in calibrator. The gold star for photography editing monitors has always been Eizo, but kudos for Benq now making monitors for photographers. Checked Apple, their current displays don’t have/support Adobe RGB colour space? As for why not? Especially if you want a colour calibrated workflow PC is the way to go.
Who knew? Found the setting on my monitor to reproduce colors values at 0-255, recalibrated, and the result is like night and day. The colors and tones display significantly better. Thanks Glyn!!!
No good for photography or modern 10bit video, though.
@@davidfrisken1617 Intrigued as to why using the full range 0-255 wouldn't be good for photography. Forget the video as this video was about 'photography' hence the title
0~255 (256) is only 8 bits. 10 bit has 4x more values (2^10=10124) and thus way more color accuracy. Now you can stretch your dynamic range without losing color precision.
​@@boudewijnj.m.kegels5198 not accuracy, just precision. 8-bit is enough for sdr content and photo printing (it's not hard to beat the dynamic range of paper)
So interesting! Thank you!
This was so interesting. I'm having a lot of trouble with color match between my photos on Lightroom/Photoshop 2023 and how they look so different on my Huawei in Instagram. Same color profiles. Even the brightness is quite dark. It drives me insane. I have to edit in LR/PS, send to phone and then adjust them again in Snapseed before publishing them. Oh, my nervous system. Thank you for this video. Regards from Portugal.
HDMI 2.1 has a color depth of 12 bit or as DisplayPort 1.4 is limited to 10 bit, not to mention HDMI 2.1 has considerably more bandwidth.
That’s all very interesting but if the settings (default) are limited then they need to be changed … like many in the comments have discovered
@@glyndewis .. I would hope anyone who's either into a hobby or certainly a professional would know to change a simple setting.
Well deserved like. Mind blown. Thanks for sharing.
Very useful information and crispy put. Thank you!
However, I would love to know how to ascertain if am HDMI is Full or Restricted one?
It's not the cable ... its the settings. If you are able to dive in and change them in the graphics card then great but if not (like many and expecially Mac) then alternative input like USB-C is advised.
@@glyndewis thanks for your response but then my MacBook doesn’t have a USB-C as it is an older model.
based on this presentation I switched my BenQ PD2700 monitor connection from the HDMI port to Display Port and to the USB-C port on the CPU (M1 MacMini). A huge improvement. Thanks!
Fantastic to hear this! ðŸ‘ðŸ»
Great information great advice tanks
I’ll have to check my monitor cables now. Thanks!
I'm using a Display Port cable for my Benq monitor... but it was just a matter of chance: it was the first cable I picked! 😜
So presumably there would be a way to change the default output from limited to Full? If so, how is this accomplished?
Great info! Did you talk about colour spaces? SRGB vs Adobe RGB? My understanding is that the larger colour space Adobe RGB is limited when it comes to seeing images on the webb, screen and for most printers and printing companies, they convert it to SRGB anyway. Who should use Adobe RGB in their workfkow?
sRGB is a smaller colour space and is used for the web. Adobe RGB is a larger colour space and preferred space for editing and for printing.
Very useful info. But calibration of my BENQ always fails because it got really bad edge bleeding in one of the corners :P
Yes, this is not public knowledge as I only noticed this when playing the PS4 game HUE on my monitor where the in game purple colour is very thin & light, but using that same monitor to watch TH-cam HUE game playthrough capture shows actual deep purples which is unexpected.
Further investigations shows I need to set the RGB to "Full" instead of the default "Limited" on both my monitor & PS4 settings to fix this.
It took me years to find this out to the point that when I went full range it was hard for me to adjust, as in limited mode it seemed easier to the eyes.
Nowadays I find a lot of desktops users having no idea and sitting with limited range for all their life.
ðŸ‘ðŸ»
I am using DVI but am still having colour issues printing etc.. just as you describe. I export as SRGB then print from Faststone and it is correct, print from adobe and it is junk.
Good to know! I am going to ensure I use USB-C for connecting my Mac Studio to the monitors - although they are low priced Samsungs, so not really going to make a heck of a lot of difference. Every little helps
You should see a pop in your blacks. I did on my sons Samsung.
Found out about this years ago and set it to full range since then.
Great vid! The title of the vid kinda freaked me out a few days ago since my graphics card was connected to HDMI. Recently (ok, last night lol), I've calibrated my two monitors using the ColorRite i1 Profiler Pro, and they both achieved a rating of 2 & 5 ΔE after validation. Check! These monitors are not as high-spec as the BENQ, and they only offer HDMI and VGA connectors. To connect them to my graphics card, I'm using a high-quality Thunderbolt to HDMI cable. Surprisingly, the monitors appear to be color accurate on screen. So, I was thinking- uh...okay.... But after watching this the second time, I missed a little detail on HDMI settings, and I realize my HDMI settings was set to FULL already!! WHEW!!!!
Being a headshot photographer, I'm constantly concerned about the quality of color output when my work is printed for my clients.
Thanks for this ! I've just looked round the back of my monitor and, in addition to the HDMI input that I'm currently using (but about to change) I have a display port input and my MacBook Pro has USB-C. Can I simply buy a USB-C to DP cable ? And, if so, any brands to prefer over others ?
Thanks, Stuart
DisplayPort cables all tend to be pretty high quality so anything should work
I found the information informative I have my Dell P2412HB monitor connected with a Display Port on one end connected to the computer and the other connected to the DVI-D port on the monitor. The cable is Display Port to DVI-D. Not sure how much difference this makes never calibrated the monitor. My camera is a Canon EOS Rebel T5 1200D. I use the software that came with the camera on disks provided by Cannon. Upgraded to Digital Photo Professional Ver 4, and Picture Style Editor.
Interesting! Tyvm!
Hi Glyn,just to ask,where is that benq software.i found brand new benq(think 271 or 270,waiting delivery)so soon would like to calbrate it.ty
Here you go; try this link on BenQ website www.benq.eu/en-uk/support/downloads-faq/products/monitor/palette-master-element/software-driver.html
ok, before people go and buy another cable, after reading the comments and doing a bit of research it turns out there is nothing wrong with HDMI just be sure to go into your graphics card settings and make sure it is set to FULL RGB and not limited .
Great but can you just tell me how I change this setting on an Apple M1 GPU Integrated graphics Card???
@@glyndewis haven't got a clue, I'm sure you didn't mean the video to be misleading, I love watching your videos, I don't think you stated in the video it was just for mac's? When I watched it I thought I might have to buy a different cable until I spent a bit if time researching and when I checked my gou it was already set to full rgb.
Good information Glyn
What your guest said is a little bit incorrect. 16 - 235 is not cut off or limited range. It's known in the business as Video range, Head range, or SMPTE range (named for the standards body that created it) which was a way of sending a compressed analog signal (64-940, 10 bit) over the transmitter which would be uncompressed in the television. In the digital age we still hold onto SMPTE range and interlace signals as well as 29.97 and 23.976 for audio even though today's TVs are progressive scan and there is no color subcarrier to create a time problem for a 60hz system. The cable has nothing to do with whether your signal is SMPTE or computer Full range (0-1023 10 bit). You just have to know what mode you're working in for the monitor calibration to be correct. Computer screens are usually sRGB which is Rec709 color space, the same as ATSC HD. That said, if you want to manipulate your images it is probably best to capture raw and move the images from your camera onto your computer and import the raw files into your photo application. Raw has greater color depth than your monitor is capable of portraying. If you're making prints you may want to work in CMYK so that you're sure what you're printing in terms of color.
Nope. Most printers accept Adobe RGB because they feature more than just the standard CMYK inks, eg green, red, light, and/or light light blacks, and many other combinations. The printer will make the conversion to its own colour space by its self. Especially for higher end 5-12 ink systems
I have a question. In the Nvidia control panel options, when connected through an HDMI cable, there is an option called "dynamic range" which, according to the description, has a range of 0-255. My question is, isn't that option the equivalent of connecting a DisplayPort or USB-C cable?
I am pretty sure it is. The advice in this video is misleading, you can just set it to full range.
Just set to full range and then see if you can also change the bit depth from 8 bit to something like 10 or 12 bit color to reduce banding as well
wow thanks for eye opening video
super nice info, didn;t know that at all... Dr Chris Bai is very smart and aware..
I have two monitors connected to my editing PC and my work laptop docking station - just took me ages to check all the connections to make sure my PC was connected using DP to my main photo editing monitor! Thank fully all was OK..
Thank you â¤
Reading some other comments I went to my nvidia control panel and discovered I needed to change to full range so I recalibrated and got even better delta readings 0f .75 delta. I think my success with passing before is that my hdmi connection is 2.1 , not 2.0 which might of helped make it work. Oh well, it was time to recal anyway. Those who have geforce nvidia cards should check their nvidia control panel to see what their current settings are.
Thanks for that Al
He's just another spammer a-hole fishing for clicks by spreading lies, like the cable has anything to do with how you can tweak your monitor settings. U can make any 'interface' look like any other by changing the settings.
As long as your display is using the same data rate settings as your creative software is expecting to deliver to its all good. 8 bit/10 bit; Data/Video; full/limited.
It is the mismatch in profile that is the issue. The cable is just one component that must align. Hdmi is equally capable of being used as any other cable to deliver correct colour - if the software in the display agrees with that on your computer. All you need to do is check your settings. The software you use and the context you work in determines which are the correct settings to use.
Yep … not saying it’s the cable … it’s the settings as per my pinned comment
If this really works its going to be life changer, thank for sharing
I think this video has many misconceptions, and I am really surprised to see a VP from ICC supporting this.
HDMI as an interface (and the relevant cables) is perfectly capable carrying full range signal, as well above this, such as 10bit HDR. I can’t post links, but feel free to refer to the HDMI specification.
There is nothing wrong with connecting through HDMI.
There are two things that might be wrong, and both are user errors.
The first is that your monitor is clipping the range to limited. Many monitors have the option for limited range in their settings, to conform to broadcast standards. Believe it or not there are people in the industry (video) which are having monitors calibrated to that range to conform with the standards in their broadcasting facility. That’s perfectly fine, and they know what they are doing.
A user however that are not familiar with that concept might have the monitor on limited range which will produce unpredictable results (especially if you try to calibrate to full range).
nVidia drivers
There was a time in the past that Nvidia Drivers were defaulting to limited range, around 2019. Not sure why, it was really stupid. It’s not a problem anymore (at least I haven't encountered any issues these days). You can check what your Nvidia driver is outputting if you go to the Nvidia Control Panel -> Display -> Change Resolution -> Use Default Colour Settings, where Output Resolution is defaulting to full range. If not change it to full range if that’s what you desire.
Now, as you can see two different things might be wrong, the monitor and/or your graphics card, so it has nothing to do with the connection (HDMI). You can still have displayport connected, and your driver can output limited range.
Please don’t put information out there that is inaccurate.
ICC also should try to focus and fix the issues on operating systems with ICC profiles. What a mess. No joke that people are calibrating by uploading native LUTs on monitors, which don’t work for photographers that want to embrace a screen to print workflow.
How about the internal connection by which the screen is connected to the motherboard in a laptop or all-in-one computer?
Very interesting Glyn
Glyn, your guest said that full range hdmi is fine. How do you know if you have the full range hdmi cable? When I use the palette software on my benq 270c I get that it passed with a delta under 2. I know I have hi speed hdmi cables but I don't know if that means they are full range. Very confusing, especially since I'm happy with my prints and able to get a good match with screen in the final product.
If PME gives you DE less than 2, then your are getting full range signal from HDMI.
​@@chrisbai0605 Thanx
Ironically, I was just searching for a new cable for my BenQ because I reconfigured my studion office. My question is: Is there a preference for either 4k or 8k display port cables? Does it matter at all which one you use?
Think about the refresh rates that the different standards, cables, graphics card and monitor support as well.
Windows OS content is always limited it could be in a full range container BUT then raise blacks appear issue that could be chained so content like games can be "double" limited;
Glyn, I know this is a silly and off topic point but I have
to say, Thank You, for pronouncing Consortium as con-sor-ti-um.
Here in the US, all I ever hear is "con-sor-shum".
Back in elementary school ('57 to '65), I learned to read and
speak English, not whatever "con-sor-shum" is.
These days, you hear "con-sor-shum", even in high level "professional" circles.
Personally, I think their language skills are Tiit. ðŸ˜âœŒðŸ––
My 27-inch FHD monitor doesn't have a DP port, only an HDMI port. But my graphics card (GTX 1650) has a DP port. So will using a DP to HDMI cable still produce the same colour results as a DP to DP port/setup? I found many of these DP (source) to HDMI (output) cables on Amazon. Will buying one benefit me?
If you can chnage the settings on the graphics card to full range them no need to change the connection. See the pinned comment at the very top.
Actually its depends on what color mode you Video Cards send to your display. And it work the same way on both HDMI and DisplayPort.
Just make sure both monitors and video cards are set to the same Full Range RGB with 4:4:4.
That sounds much more real😠thank you
Absolutely correct. HDMI does not limit RGB in any way at all.
I would say if you are not a techy person and want to have a simple input -output no error result, then DP or usb-c cable is the simpler solution for you…
@@w.k4332 Thank you
So you do this on an M1 / M2 Mac with an integrated Graphics Card by .... ?
I worked in a monitor service for years. I don't want to rate the video, I'd rather ask.
Is it possible to carry more bits than 8 on the HDMI cable?
Is it conceivable that there is an HDMI standard that does not have reduced bandwidth as a default?
Is it conceivable that the device communicates the displayable bandwidth with the display from the first moment?
I note that there is also 8k HDR 120Hz (16bit/channel, 48bit) via an HDMI connector... HDMI2.1 127.75Gbit/s with DSC (Display Stream Compression)
might also want to link to linus tech tips video on HDMI cables and how so many of them (even top brands) do NOT meet specifications.
Hi Glyn, probably not the best way to present this issue (if there's a failing). As I understand from your talk that HDMI can be good but not always. Can you enlighten us in what situation HDMI is not performing correct and how to check this?
Hi Roland ... if you are using HDMI and you have the option to alter settings in your graphics card then to set this to full range is the way to go. If (like me) you are unable to dive into the settings then using another input such as USB-C will work great. Hope this helps.
I use display port for my windows machine to my BENQ 271 but recently got a Mac and tried to connect it with usbC. However, it didn’t work despite trying more than one cable so had to resort to HDMI.
Does event "high bandwith HDMI" (4k@60hz) are still "mid range"?
Otherwords - does HDMI is just mid-range as a default "because-this-is-how-it-is"?
Thanks a lot!!!
Probably being a bit thick here Glyn, but if the problem relates to the wrong cable between your PC and the monitor, what about the cable used between your calibration equipment and the PC?
Of what importance would that be? It's reading out a certain signal and sending it to the monitor, but it's not exactly constant streaming live feed. USB-A./B would suffice C is overkill, but probably used anyway on newer models.
Glyn i think y need to make another video about this wnd go deeper,cos there are still unclear things😊
N I don\t think it's needed if people see and read the pinned comment too
If the graphics card outputs 16-235 and the monitor expects 0-255 you will know, the colours will look washed out. Pretty simple to change this on windows, don`t know about mac. Anyway in windows it detects if it is an monitor or tv and this setting is set right by default, at lesat with amd/nvidia cards, i have both.
Mac its not possbile and with regards to nvidia, there are many comments form people sayijng they have now gone in and changed the settings ... so didn't happen by default
​@@glyndewis Well, in my experience it always happened, anyway i think people wich calibrate their monitors should know about the full/limited story it`s kinda one of the very "basic" and important knowledges in my opinion, or maybe it`s just me with my editing/playing video history. Regards.
I have several quibbles with what your guest claimed. If an HDMI cable has sufficient bandwidth to pass the intended signal, what is seen by your your monitor is a function of what was sent to it from the source (graphics card, stream, etc.), plus any EDID information at the sink (monitor/TV). One could use USB-C or Displpay Port cables instead, but neither influences the quality of the signal in any way. Again: assuming that the cable can pass sufficient signal bandwidth.
Also, what your video monitor displays has nothing to do with the quality of your image at the printer end. Send a RGB-High, RGB-Low, or YCbCr signal to your monitor. That does not matter to your printer. Your source's application software, and your printer driver and printer firmware decide what is printed and how.
Exactly what has been answered many times in replies and comments already. It’s the settings not the cable. If your monitor isn’t displaying colour correctly then it DOES influence what is printed because what YOU see affects how you edit, so your point there is completely wrong.
If I understand your above answer correct, maybe you will edit the videos title?
@@glyndewis You seem unconvinced about your guest's misconceptions. Think about your system. Does your printer use the same technology to form its images as does your monitor? If not, there is a lot of room for mismatch. What you see is not necessarily what you get. Making edits? More errors will be included. We tried to get around this issue in the 1980s with Postscript and Display Postscript, but the CPUs were too slow to complete the work-flow in real time.
This was a super interesting video - thanks! I had never thought much about it but it makes sense that HDMI wouldn’t display the full 0-255 range when you remember that it’s a standard for consumer video where users most likely won’t register or won’t need to register all of those colors. It certainly wasn’t made for evaluating professional color photography.
Side note: I love the Benq 3220 monitor I’ve been using for the last year and a half. Fantastic monitor and color representation.
Actually no. HDMI has no issues displaying full RGB or 4:4:4 chroma just like DisplayPort. You just have to set it. I’ve been doing this for years and HDMI and Display port have identical image quality, with the only difference being bandwidth which effects how high resolution + refresh rate + bit depth you can choose. For example DisplayPort 2.0 and HDMI 2.1 can do 4K 60hz RGB with 10 bit color but HDMI 2.0 is limited to 4K 60hz RGB with 8 bit color
Absolutely right.
Is the VGA Port okay to use though?
I’ve had the problem with calibration causing a green tint. I wonder if this was why.
Few people even remember the DVI cable connection in the back of some monitors. This is a true digital interface and also sends trucolor to the monitor in a much better form than simple VGA or HDMI it used to be that some video cards wouldn't let you run certain video modes unless you had a DVI cable
HDMI & 'Display Port' & DVI & even VGA can all look about identical (VGA being slightly to a lot fuzzy & ghosty, depending on cable quality) & it's just about the settings, like the 'luma cutoffs' & the 'bit depth', which has nothing 2 do with the connection(s) but the $upport of the $ystem. If something looks 'wrong' U can ADJUST it = fux sake. U can even tweak the gamma curve in software 4 free.
Actually HDMI is copy of DVI that was paywalled by patent trolls.
And also there is no such thing as "limited range" in both DVI and HDMI specs. DVI always carries RGB888 data in 8b10b(TMDS) encoding.
Thank you ðŸ™
Is there any way to check if my hdmi is using limited or full? I’m on a Mac mini and it doesn’t have a display port and my usb-c is being used for something else.
Maybe they can prevent with explanation in the connection notice or ……just not deliver the display with hdmi socket, I mean for the pro or semi Pro Display.
Most video drivers have a utility (NVidia and AMD for example) to let you check and change the color mode for HDMI output between full and limited. Limited is often used when you connect to a TV type display. You may have to check your displays onboard settings as well to ensure it is also set to allow full color range as an input.
I have yet to use an HDMI monitor on a computer and get limited range, but I suppose it is possible, thus YOU should check before calibration. If you know you need to calibrate your display's color profile, you cannot avoid doing the required research.
This has already been said many times and is in the pinned comment 🤷â€â™‚ï¸
how would you set a mac mini and an lg monitor to expect full range?
That's my problem so too but I have discovered with the HDMI cable, you can do much less adjustments.
Now with a display port cable you can adjust in: system settings/ displays, resolution and color profile.
By chance I have an BenQ monitor, and that stays in the list of color profile, but also Adobe RGB'98, etc.
you are a hero 💪
That's interesting. I don't understand why Blackmagic's Decklink professional color grading card uses HDMI.
at 02:19 he said there is 2 colour format at hdmi
is there any way that we can choose full range mode on current hdmi cable/monitor?
If you are windows based and have access to graphics card setting yes
I have a question. Does it allways happens or in some cases the use of hdmi does work ?
is VGA to USB-C cable better???
I have a MacBook Pro and two BenQ monitors. I don‘t see there any way to change these RGB range settings for these monitors other than colour space. As far I know for 4k i need only a newer HDMI cable. My calibration was validated, so why panic;-)
Correct...you can't change them on Mac so best option is to just use a different connection type. Re your validation .. if the Delat E is
I have had issues where I've sent images from a computer to a TV over HDMI, and the TV seemed to be overloaded by the computer, as in the contrast was over the top, loosing the darks and brighter parts of the picture, tuning the lower levels into solid black, and the upper levels into blown out white.
This kind of explains it, the computer was outputting full range, but the TV was expecting limited and could not handle the extra range. Now how do I fix this. I did look for settings, but didn't get very far.
This almost sounds like a carry on from the early composite video analogue TV days, where the actual transmitted signal range was greater than what the actual image used, the signal would go beyond black for sync pulses, and you didn't want to go all the way for white either as that equated to zero RF power in the Vestigial Sideband Modulation (VSB) as the TV receiver is now just looking at noise. Now if you scale all of this into a zero to 255, 8 bit data range, the actual pictures takes on only a limited range.
With my troubles, I kind of figures something like 'signal range' was beyond the TV, with analogue, VGA etc, one can attenuate the signal levels and get it into bounds, but digital HDMI, the is much much harder, you need a pile of electronics to take in the digital values and rescale everything, yuk.
In my case I just ditched HDMI and used good old VGA, that luckily both supported.
HDMIshould look identical to DisplayPort assuming it’s set correctly
I’m the current maintainer of DisplayCAL (an OpenSource display profiling system) and DisplayCAL detects Full vs limited range and does its thing accordingly and if you are into colour calibration you generally know about these things. I don’t think it is a good suggestion to not to use HDMI just over that.
I do and never heard of displaycal
I looked up DisplayCAL and it looks like it hasn't been updated since 2019 - is that not true?
DisplayCAL is a well-known cross-platform alternative (based on ArgyllCMS) to proprietary commercial display calibrators. It supports a wide range of devices, monitors, and operating systems. DisplayCAL has been relied on for many years by enthusiasts, installers, and developers of custom color calibration software.
@@FallenStarFeatures So it isn't true, it has been updated?
thanks
Huh, I had no idea!
I've always used the display port as I heard about this problem from Eizo
Hello little question, I saw on your description that you use one monitor for photos and one for videos, why would you use a different monitor ?
Hi Patrick ... this is purely for the space that the other video I use provides with it being ultra wide format ... I have space on the one screen to have premiere pro and audition open up and in view at the same time.
Is there any way to influence the usage of full or limited
There is a way to change settings in the graphics card if your system permits it
Never would’ve thought of this. Is it ok to use an hdmi to display port connection cable? My laptop just has hdmi ports.
If you're able to go into Graphics Card settings as you can with some and change it to Full Range then sure thing
So this would also apply to connecting your camera with the computer via HDMI, isn't it? Do modern cameras have the full spectrum 0-255 at their HDMI outputs? Sometimes they even come with a micro HDMI output. Are their full spectrum micro HDMI to HDMI cables then?
What good is it to load the Fotos or videos from the camera to my computer via HDMI, they might be color inaccurate from the start, isn't it?
It’s not the cable it’s the hdmi settings. Check out my pinned comment. If you’re transferring from camera to computer what cable you use has no effect on colour.
TL;DR: if you use HDMI cable you have to *verify that both source and the display are configured to use full range.* Due historical reasons, TV sets used limited range (the full range values were used for signal syncronization because TV sets didn't have dedicated wiring for hsync and vsync similar to computer monitors). And in the distant past of HDMI signal somebody had stupid idea to implement this limited range in digital domain.
Note that *DisplayPort also supports limited range* so you should verify that setting even if you use DisplayPort. And the same applies to USB-C, too! Luckily the *default* setting is typically full range for DisplayPort and USB-C but you shouldn't assume that if you want correct colors.
If you have both source and display set to limited range, your 8 bits per color panel turns roughly into 7.5 bits per color panel. Not terrible but not great either. If you mix the setting, you either get washed out colors or crushed blacks and whites.
I changed to a fiber optic HDMI cable and the change was brilliant.
It shouldn’t matter what cables you have considering this is a digital signal not analog. Quality still matters but digital either displays an image or it doesn’t while analog can be anywhere in between. Just make sure you set your stuff to 4:4:4 or RGB
