It was working earlier that day. I then took it off and tried to launch something a few hours later and it didn't work. It isn't my hardware as I was using it for days before then and the white led comes on when I open games. Audio is passed through (it gets passed through the USB) and it says the HDMI is connected. I have an RX 590 running latest drivers and a Ryzen 5 3600 and I got games to run on it before. I tried the driver.exe, unplugged and plugged in the HDMI many times and deleted and re installed the oculus app. I don't know what to do.
Try closing Oculus app and unplugging the Rift from both the USB and HDMI. Plug the Rift back in then restart the app. If you still get no output on the lens it may be the cable. Good luck getting a replacement as I need one (only working on one lens.)
