I've looked around and the answer seems to be to make sure both video feeds are coming from the graphics card and not the onboard gpu, but my computer doesn't have an onboard gpu so this isn't the issue. Also in a new developement, the game will load on my computer monitor but I will only hear the sound sometimes and see nothing but a black window, the view in the hmd is the Home loading screen for the game. SOLVED: The problem was with unity switching resolution to 0x0. The solution was to start the game that isn't working, while it's open change resolution of main screen to a different value then back again, then restart steamvr app.

I set up my vive after having it off for awhile. It was working before but now I can't launch games. Also an error comes up when the steamvr app starts: "Compositor not fullscreen (-202)" I can click the link that makes it fullscreen or wait until it goes away with the same result. The startup app, Steam VR Home, works fully except for a few environments that seem to just not like me, but games won't load. The game window on my desktop display is solid black with no response, the steamvr app displays the game as 'unresponsive,' the loading screen for the game is displayed on the hmd, and I can hear the game audio sometimes like it's running in the background but see nothing. Things I've tried: -enabling/disabling direct mode, I have to run enabled to get anything to work. -unhooking the vive and reconnecting it -removing steamvr usb devices through settings menu -restarting computer, this worked more often than reason would dictate in the past. -reinstalling vive and steamvr software -updating video card drivers -rolling back video card drivers -verify integrity of game files on old games that used to work and new games
