How can I prevent the game screen from being displayed on my PC monitor while playing games on Steam VR?

So, I use Oculus quest 1, and I want to play ETS 2 in vr with my friend, but heres the problem: he doesn’t have a microphone, so how can I see my screen while ingame? Like, a separate screen that shows the monitor output, that i can move and all that stuff, because i saw that in one stream, that looked kinda cool Can somebody help me out?...

my headset and laptop are still lagging when i open steam vr through virtual desktop and ive checked for updates and there is none and ive verified the steam vr files and that still hasnt fixed it and im on a quest 3 with a 4050 msi gaming laptop and the laptop and my headset have never done this before and its been doing this for about a week now somebody help me...

Yesterday I used Steam VR without any problems, but today for some reason it doesn’t want to start. I tried different methods, nothing helps. When launched, nothing happens, Steam VR does not appear and after a couple of seconds it closes in Steam.

Not sure where to get help with this but I just came across this board and thought someone might have an answer. I set up openvr2key so I can bind a screenshot button. That worked. But I tried to unbind the in-game control so I'd stop teleporting in walkabout golf when I clicked the button, and now openvr2key no longer detects any button inputs. I tried setting everything back to default in the steam vr settings, but it still won't pick anything up. It still detects my headset and the current running app....
