After running Assetto Corsa Competizione in Steam VR mode for the first time. Monitor resolution instantly dropped to 640x480. Was able to set it back to native afterwards. VR display was fine. Ran it again the next day. Monitor resolution was fine, but Vive HDMI audio was crackling (was crackling earlier, but then thought it was an app issue). Went for a reboot. Black screen, no signal, after Windows startup. Monitor detected as generic pnp monitor. Resolution locked at 640x480.


Unblessed and blessed it again (BIOS, DDU, etc).


Same. Black screen on driver installation. Other 2 displayports work fine. Hardware defect?
