This is a device that allows you to stream content from virtually any device with an HDMI out, to your headset. This is different from Steam Link and Virtual Desktop as you are not locked down to network performance.
This essentially turns you Quest into a monitor. Games like Call of Duty can't be played through Steam Link or Virtual Desktop because there are too much data to be transferred via a network connection.
I tested this with Call of Duty Black Ops Six. It does play, but only at 60 FPS, which makes it nearly impossible to compete online. I was shocked with how good the graphics were, even at 1920X1080.
If you are looking to play your PS or Xbox in your headset, or any other device that you can get an HDMI out for, at less than $25.00, this is a steal!
