[RESOLVED]Black Screen & HDMI Disconnects

Started having some real trouble only 3 weeks after my Rift arriving, essentially it started with 'hdmi disconnects' throwing me out of DCS but now I get a black screen AND an hdmi disconnect (probably the same thing) but this is whats weird, only in DCS, everything else works fine. So I tried repairing DCS but that didn't work so I assume my next step is a complete re-install...

May I ask, has anyone else experienced this issue and have they found a solution?

Thanks in advance

edit. okay, I have found another thread related to this issue, seems that many Rift owners are suffering these problems, what I don't understand is how my Rift which is only 3 weeks old, worked perfectly all that time in DCS with no problems suddenly have serious issues.

Solution: Disabled Asmedia controller which has proven to be the #1 fault for hdmi disconnects and 'black screen'.

When you put it on, you may pull out the cable from Rift

twobells, not sure why it happened to me either. It worked fine, then it just stopped. Going with a DVI or DP (can't remember) fixed it. I guess it's an Nvidia thing.

my rift was running fine on usb 2.0. after the arrival of the usb 3.0 controller hdmi disconnects started. I switched the usb-cable of the glasses back to 2.0 and things were good again. no disconnects anymore. strange...

Black Screen & HDMI Disconnects

Same here, problem was solved by plugging the hmd on an onboard port, sensor still on the usb3 card

Happens when:

-HDMI Voltage Drops (as the OR is out of HDMI Spec)

-USB Voltage Drops (Having Sensor and HMD On the same cheap USB controller)

-Loose Cables (the Cable on the HMD can be Pulled / wiggled loose from use)

I have a DP connector let me try that.

Did it affect your DCS framerate at all?

TIA

I do not think so.

If your Rift disconnect problem only occurs in DCS world, try moving power hungry USB devices (lighted HOTAS, RGB keyboards, etc.) to a powered USB hub rather than plugging them directly into front/back USB ports.

I noticed all of the llights on my HOTAS Warthog throttle go off at the same time my Rift disconnects. This revealed that ALL of my PC's USB ports were shutting off - apparently because too much current was required for all of my devices.

Since plugging my power hungry USB devices into a powered USB hub I have not had a single "Rift disconnect".

Hopefully this helps someone else. What a rellief!

i had exactly the same problem as you are....

i solve it by changing Nvidia drivers ....problem solved

Which driver version are you using now?

Well, after what, 2 years?, my Rift gave in today. No HDMI connection, period. I tried all the tricks, including NVidia drivers downgrade. I had no recent software changes, but I did get intermittent HDMI connection errors in the last few days (cured with restart or reboot). Does it sound like a bona-fide tired cable? Contacting Rift support, will see what they say.

Perhaps.

I assume you took the faceplate off and checked the HDMI connection into the Rift to make sure it had not come unseated a little? Any kinks in the HDMI cable where it comes out through the strap? It can develop twists there.

Also just for grins try a repair of Oculus Home?

If so I would probably try getting a new HDMI cable from Oculus.

I have been running mine hard , almost daily for the last year and a half, thinking about ordering another HDMI cable from Oculus just to have as a spare if needed.

Yep, tried unplugging/replugging and moving USB from Innotech back to motherboard. Oculus software just got updated itself, no change. I get video/sound in HMD for a few seconds after launching Oculus, but the picture is static (does not move when I turn my head). Then I get a warning about 'poor tracking', and then screen goes dark and I get an error 'HDMI not connected'. OculusVR process may freeze or crash at this point. It seems it lacks some type of feedback from Rift. Is this consistent with bad cable? Ironically, my 2-year EU warranty just ran out last week )))

Hard to say for sure, but it is sounded like it. Any noticeable twists in the cable coming out of the headset?

If what you describe was happening to me, I would probably order another cable from Oculus to give it a try and see if it clears it up.

I have a clip that I attaches to my shoulder. I never felt like the cable on the HMD would stand up to the strain. Just one of those badge holders with plastic band and a clip.

But if you have a HDMI-DP adapter, you might give that a shot as well.

I wouldn’t expect much in the way of help from Oculus support from my experience with them for the same issue. You can check the HDMI connector pins for any obvious signs of damage. In my case it looked like the recessed +5V pin was bent. I had the black screen issues before Oculus were selling replacement cables and they refused to entertain the notion that the damaged pin was causing the problems.

After almost a year of it not working I decided to try again back in March. Magically it started working again. No idea what the issue was.

UPDATE. Today, after 2 weeks of DCS withdrawal, Oculus shipped me a replacement HMD + cable under warranty. But this DID NOT solve my problem! I am still getting freezes while loading Oculus Home and/or black screen, then 'HDMI not connected' error.

Moreover, after clean reinstall of Oculus I am now getting crashes a few seconds after PC reboot and Oculus launch. I noticed in the Event Viewer that OculusVR.exe crashed the same second as OVRServiceLauncher process was saying that OVRRedir.exe 'died with 4'.

I had another ticket before trying to resolve this bug (it was spamming my Windows logs) but after numerous tests and reinstalls I was told by Oculus support that 'it was normal'!! Now this bug does not seem so innocent - I hope they can investigate better.

Another of my theories is that one of the Oculus automatic updates broke compatibility with my Windows 7 and/or .net 4.6.2. All my non-VR games and programs work fine so I am not willing to try complete Windows reinstall or upgrade to 10 in order to fix their bugs.

BOTTOMLINE: Oculus developers and support stuff are complete and utter rubbish!

I gave up years ago, with intermittent HDMI and went with a DP adapter. haven't had issues since then. SkateZilla and others have posted about HDMI specs not being quite to spec that can cause issues.

I actually found a spare HDD and installed clean Windows 7 with all the same drivers etc, and the problem is gone! So it is NOT a hardware problem, just my old Windows got clogged somewhere.
