I received my 8K X several weeks ago, but only just finished the PC build itself. I have submitted a support ticket (#23807), but realize it’s CNY today. Hopefully my support rep is enjoying some holiday and not worrying about my problems. I’m past the 14 days (not sure why exactly that’s significant, but it seems to be), though it only came out of the box three days ago.
I immediately replaced the cable from the original 2xUSB cable with the new 1xUSB cable. I installed PiTool v274 and plugged in the HMD. USB connected, but no DP. I tried a few things, but then remembered Kaspersky has Webcam Protection on, so I turned that off. Then it connected, so I assumed at the time that fixed the issue. It remained connected and I was able to complete the setup and put the HMD on to look around at the planet scene.
Then I installed SteamVR, but I was stuck in that loop where SteamVR would crash and you have to unblock the two modules (Pimax and Controllers). Then restart, only to have it crash and quit. It was tracking in PiTool, but nothing working in SteamVR. I forget what happened in the interim, but then I noticed it was no longer working in PiTool, either. USB is working, but DP shows disconnected. I get the 10600, 106XX, and 109XX (10936) codes and the Diagnose tool says to plug in DP/HDMI.
I tried all three of the DP ports on my 3080ti, all of which are otherwise known to be working fine, but that made no difference. I also tried different USB ports (3.2 on the motherboard and 3.0 on a PCI card with SATA power). So I reinstalled PiTool 274 but made sure I had Kaspersky AV paused (installer run as admin, FWIW). No change. Next I tried PiTool 270. No change. I tried the original 2xUSB cable. No change. I went back to the 1xUSB cable, no change. Tried PiTool 274 again, no change.
I will try another PC and see if it happens to work there, as well as a few other suggestions (thanks to u/FaySmash over at r/Pimax_Official).
Any solutions or other ideas how to troubleshoot this?
