So myself as some of you had a problem with Oculus Rift S going Black Screen and having Static Noise. Scroll down to solution if you want to avoid reading all my steps on the way getting to it.
I had a constant loss of connection with my Oculus Rift S for a past month and for the last 2 weeks especially.
I got a notification that DisplayPort connection was lost, but sometimes my VR rebooted instantly, sometimes not and I had to reboot PC.
It all started about a month ago, but was getting worse. During playing or even when I was in Oculus home I was hearing a static noise and sometime my Rift S freezing for a second. It also affected my sound during playing (with some sound artifacts as well).
Then after some time (from 5 mins to 1 hour), I saw a black screen, bip noise and then black screen and SteamVR says that connection with my Oculus device is lost.
I have spend 2 weeks talking with support and here is what I have done:
1. Uninstalled and reinstalled the Oculus Software completely. (including cleaning of ALL Oculus records and folders)
2. I have analyzed my video card performance and adjusted graphics accordingly. Tried to reverse to older drivers.
3. Repair the Oculus Software, reinstall it - dozens of times.
4. Uninstalled and reinstalled SteamVR.
5. Checked that SteamVR and oculus software are up to date.
6. Checked that Windows 10 is up to date.
7. Checked that my GPU driver is up to date.
8. Checked that USB drivers are up to date.
9. Tried every USB Socket on my PC (4 EA) and tried adding a USD HUB with power adapter.
10. Disabled USB selective suspend setting in the Windows Power Options.
11. Checked the DisplayPort wire is properly connected – and as I have 2 of them – tried both
12. Checked that the DisplayPort wire connection in the headset is connected properly.
13. Have not antivirus, but checking PC constantly for viruses
14. Have no Razer Cortex Boost
15. Ran the Oculus software in Administrator.
16. Turned the volume on the Oculus Rift S down to 30% (and hear less static noise)
17. Restarted the Oculus Service (hundreds of times)
18. Restarted my PC (hundreds of times)
19. Tried my Rift S on another PC (less static noise, but still crashes or breaking USB connections)
20. Tried Oculus public test option
21. Have no cable extenders
22. Processed Windows System File Checker/Check Disk/MemTest
So none of these helped and everything was getting worse, so I have bought a new cable and everything works great now.
What bothers me is the fact that my cable was not damaged or at least I do not recall doing so, but performance was degrading from week to week and then dramatically during my experiments with support. So maybe cable resource is limited? I have used it for like ~700 hours before it have started to make troubles for me.
