I was having the same problem with the Luna splash screen appearing either showing WiFi or prompting for WiFi in the connection options, even though I had selected Ethernet in settings. I also had the 'jumpy mouse' effect. Thus this video was of interest as was your superb video describing the Luna product. However I found that my Ethernet was functioning OK. I have a new M4 iMac with a 2016 iMac as the second screen and as WiFi isn't even enabled on the 2016 iMac I found the whole thing quite confusing. I experimented by disabling WiFi on the M4 and this fixed the problem, with Ethernet showing in the Luna panel. As some things rely on WiFi I tried changing the service order in the Network settings on the M4, with Ethernet first and WiFi second, hoping this would allow both to be connected without this issue. But this caused the original problem to return. It seems that Luna gets a bit confused when both connection options exist, prompting for WiFi even when everything is connected and working. I've now disabled WiFi and all is OK again. I also notice that Luna initiates the second screen far faster when the WiFi is disabled, I assume because it is no longer trying to make the choice. I thought my experience might be of use to others.
Thanks for your input. I still have both Wi-Fi and ethernet working. I find that commonly Luna Display will choose Wi-Fi, but then, if I wait a few seconds it will switch to ethernet.
Thanks for that Ethernet tip Phil. I am running a Mac Mini M2 and using my 2017 iMac as display via Lunar of course. So “Headless Mode”. My main issue is sleeping my 2017 iMac when I stop work on the computer. On the sleep command or Lock Screen it blacks out but doesn’t completely stop like it used to when running as an iMac. I have turned the iMac off completely using the button at the back but this is very inconvenient as you then have to attach a keyboard, put in password and wait for a slow boot up when wanting to use. Any suggestions appreciated. Thanks. GS.
This is the main 'problem' with using Headless mode. You could go through removing the Password requirement for the iMac, auto-launching Luna Display Secondary once you have woken your iMac, but even then you will regularly need to LogIn to your iMac.
I'm getting nowhere with my Luna display. close to sending it back. 2017 Imac and a Mac mini m2 pro. why do need a router to connect your Mac's. Im trying to connect with ethernet directly with a network cable. Wi fi just keeps taking over. Imac unusable as a monitor. 2 second mouse lag and totally blurred screen. Hate it!
The router option is the easiest and allows you to use all of the wired networking features of your Mac's, plus most people have a router with Ethernet ports so don't have to buy any new gear, other than Ethernet cables. If you have selected Ethernet as your primary connection choice in the Luna Display software, give it a minute to find that connection as it will likely find WiFi first then switch to your choice. It works brilliantly with my M1 Mac to 2017 iMac! I can watch video and edit in full 5K.
I connected my Mac mini to the IMac 27 inch via an Ethernet cable with no router and it worked great. So it goes Ethernet to Ethernet. No lag.

Hi Phil, do you have any video on how to use imac as main monitor with luna ?
yes - search my channel, even look for the Luna Display playlist
