My PC recently downloaded the Windows 10 April 2018 update. The installation of the feature update went fine. After my system booted up I started verifying everything was working and noticed that I could no longer access the Radeon Settings software for my GPU.

No problem, there was a new version out anyway so I installed 18.4.1 and bob’s your uncle, it fixed the problem. I went on about my day.  Later that evening one of my children reported that they couldn’t get the Oculus Rift to work. I checked it out and found that the Oculus software showed “No HDMI cable connected”. I check all the cables; I went so far as to disconnect all of them and reconnect them one at a time. All the USB cables were detected but no HDMI.

I unplugged the cable from the Rift itself. You gently pull back on the foam insert and the HDMI cable will disconnect. Be gentle though, if you break this cable you’ll be up a creek. It didn’t work. I figured maybe the software got corrupted during the update so I uninstalled it and then downloaded and installed the newest version. Still no go.

The only thing in the event viewer or any of the Oculus log files that I could find was a reference to OCVRLauncher not having a user session. I started suspecting the AMD driver was at fault so I uninstalled it and tried the headset using the built-in Windows driver. It worked.

After testing every version of the driver I had on my hard drive I found that the newest version of the Radeon Adrenalin software that I can run and still use my Rift is 18.2.1. Even 18.2.2 will not work. I cannot say if the Windows 10 April 2018 update has anything to do with this problem or not. To be honest I’m not sure what version of Radeon I had installed before my system was updated and I’m not willing to roll back the Windows update because I don’t have the time. If you’re having a similar issue with your Oculus Rift and AMD GPU combo, you can get the driver version 18.2.1 here.
