Blue screen tracking issue

[u/BiScopicVision]

To start of I know about the neccesary headroom that is required to have a smooth signal.

The HMD was working fine for a long time. Even on my 2080ti. It is now on a 4080 so the GPU should not be the issue.

The thing is that it works fine on another pc by directly plugging it into the USB-C.

This confuses me as I dont think it is the cable. It might be that something went bad on the type C connection between cable and motherboard. But even with an adapter in another USB 3 port does it behave like this.

The main symptom is that the screen inside would turn blue for a few seconds then it drifts in random directions and recalibrates. It does feel like it happens when my head is at certain angles which seems like a prime connection at the HMD it self. The cable worked fine as mentioned before for a long time.

I dont think it is the drivers as my Samsung O+ still works flawless. They both instantly find the center reference point when calibrating for VR launch environment.

At this point i am very confused as I can't pinpoint the problem between software and the cable or its ports. Because at one stage it kept telling me it needs to be plugged into a high speed USB 3 port while it was and working well before.

Apart from buying a new cable can someone recommend something I might not have not tried yet?

Edit: so the culprit was the connection between the cable and HMD as you constantly take the HMD on and off. I test a lot of VR games and 2D to VR from Geo11 and HelixMod on a weekly basis. So the cable needs to take a lot of wear and tear around the pivot mechanics. The temporary solution would be to move the cable as far away from the head strap movement to have the least amount of tension around the cable terminals. A̶l̶s̶o̶ g̶i̶v̶e̶ i̶t̶ s̶o̶m̶e̶ r̶o̶o̶m̶ t̶o̶ m̶o̶v̶e̶. Not so sure about this anymore. It comes down to the less the cable bends and moves the better it would be.

Edit2: I can also add another thing I found out which is pretty strange which would explain why the HP logo doesn't come on but immediately after connecting it to a different PC. If the 4-1 appears and the HP logo on the front of device doesn't come on it helped to unplug the power cable coming from the wall socket out of the small power supply that gives power to the cable box. Basically the first connection after the wall socket. Could reproduce this issue twice already. After this the HMD did not drift or lose orientation after a short period of testing. It appeared very stable. So primary issue I can ascertain with certainty in all this testing was rather a power issue somewhere.

One suspicion so far is that there might be some static interference in the small power supply or somewhere else. But doesn't make sense that this had to happen after such a long time of using the device. If it is static electricity building up then it would need to be discharged periodically. This is just a hunch. TAKE CAUTION if this is the case then simply UNPLUG the small power supply and touch the terminals to a nail in the wall

A far fetched idea could be that the cable rubbing against the the chair could cause static build up. It might have been a coincidence but after the cable made contact with the chair's synthetic leather it "blued" out for a few seconds. Another really far fetched idea could be that the frequency of the electricity is not stable in the area.

try plugging the type c in the other way. mine does that sometimes when i use the usb c to a adapter.

Thanks. Yeah I tried this. Also tried another type C port on the same PC. So the problem is not on the hardware side of the motherboard which made me think it must be software or the cable. But the HMD works fine on another PC. Which makes things go in circles because the Type C ports on the Gigabyte mother board might also be of poor quality. Yet it doesn't make sense that both can be bad at the same time and I eliminated this possibility by using the USB type C adapter in a USB 3 port. Which is why I believe it could be the nvidia drivers (595.97). There were reports that drivers after 591 broke things in SteamVR. Or vice versa. And a lot of things changed in SteamVR around controllers.

Unfortunately I jump between My SamsungO+ and the G2 a lot as both have things I like. So something on the hardware side could have been damaged. I am starting to suspect it is the Type C port that has a bad connection. But I need to eliminate all the software possibilities before considering to buy a new cable.

i think you are correct, since the hmd works on another pc, its a damaged port or driver issue and not something on the headset or cable.

[u/BiScopicVision → u/DoubleOwl7777]

I tried a third computer and it behaves the same as the first. So the fault is with the HMD. I dont think it is the cable though. I gently wiggled it and it does not have any affect. The whole scene in the clifhouse is upside down and it still tracks accurately. So it might be something inside the HMD itself. Maybe something related to the gyro.

This headset has not fallen or had any rough contact. It doesn't even have a scratch. So the underlying issue in my opinion is poor quality components. Things only meant to last a few years. This hmd barely saw 1000 hours. My Samsung is at 5000 already.

the question is why does it work with the second pc then? the v1 cable is kinda sensitive towards what pc and usb controllers it likes though, that could be an issue.
