{SOLVED} Oculus Headset black screen only sound is working, Orange light ON, Help.

[simo1000rr]

i've been having the Oculus for a month or so and it was working Flawlessly on a 2x 970 gtx with windows 7 . 
i have the Rift and the monitor connected to the first card with SLI enabled. i know VR dont support SLI but i left it enabled.
played on win7 for 3 weeks not a single issue.

I installed Win 10 . every thing was working good for 3 days , at the 4 day i went to power the Rift i get only the sound working but black screen on the display and orange light on .

for 3 days after that i tried every thing on the internet , and i mean every thing, i installed win7 back didn't work then i installed win 10 again didnt work i switched every USB around , i unplugged all USB from the PC and only left the rift alone connected to USB 3 alone , NO work . i disconnected the monitor , no work . i put the monitor in the second card and , Also no work . 3 days continuously with the minimum hours of sleep trying to fiddle around with out any thing.

at every try i would do a clean install of Oculus Run time. at every install at the page where it checks if everything is connected right  all 3 connected  :smile:
Sensor  USB 3   OK
HMD     USB 3   OK
HMD     HMDI    OK .

in my desperation at the last try before giving up i disabled SLI and i try the Oculus , Still no work the oculus was connected to the first Card.  I keep SLI disabled and i connected the Rift to the second Card . i fire up the Oculus and to my surprise it works . 

i literally had to rup my eyes so i can believe . so at this point this is the only way it works . even if SLI disabled and rift connected to the first card it doesnt work . it has to be the second card and SLI Disabled . if Enabled it again goes to black screen . if i disable it back Boom it turns on with no problem.

I understand about computers but im not at a technician level . can someone help me out . why i cant connect it to the first card , and why its not working like Before on win7 with SLI enabled , or even windows 10, i could have it work for like 3 days on windows 10 with SLI enabled and Rift in the First card. 

what could be the issue ,  Thank you in advance for any help.
 
EDIT:    so the problem ended up being a bad HDMI output on graphics card, i got a new card ( evga 1070 gtx) once connected every thing was back to normal . thanks guys for all your help.

Use a Display port/HDMI connector or swap your cards and use and HDMI extension and an HDMI interface. I did the later and all the problems resolved.

This.  The sound is sent through USB - why you still get sound even if the HDMI is not connected.  When adding extended HDMI cables, this is a common symptom (sound but black screen) and switching to a DVI or display port via DVI2HDMI dongle solves the problem.  Not sure why - perhaps HDCP (content protection built into HDMI) is less tolerant of the increased bit error rate.  Sounds like your original HDMI port got zapped or otherwise degraded.

Asus HDMI and Oculus no bueno... Use a Display port/HDMI connector or swap your cards and use and HDMI extension and an HDMI interface. I did the later and all the problems resolved.

I was using Asus GTX 770 last week on my Dk2 and I had no problems, everything was working like a charm. I upgraded to MSI RX 480 (witch is VR compatible) and now I have the orange light no image problem. I have clean fresh win7 x64 system up to date and latest GPU drivers. I was switching HDMI, usb 3.0 back and forth with no joy. The RX 480 is brand new out of the box and both HDMI ports are working on any other display/TV. I did not try the HDMI-DP port yet but, I'm 99% sure it is software/drivers/compatibility problem related. 

What I noticed is that as soon as I will strat uninstalling Oculus software while my DK2 connected and switched on, it will immediately turn on blue and display desktop on extended mode. How come this can be a bad HDMI issue than? It doesn't make any sense. 

I will report back as soon as I figure my problem out.

EDIT: Back and all working now. :smile: Way I did it is:

- Uninstalled oculus software, and deleted all left behind files and folders.
- Cleaned with CCleaner and cleaned registry.
- checked and installed KB2670838 hotfix prompted by oculussetup. (all tho all updates were installed, known installation bug) as well as KB3033929.
- After running Oculus Home,still orange light, so than I reconnected and cleaned plugs and ports from headset itself and it worked straight away. Multiple restarts and its working like before every time. I think this was a root cause problem. Bad connection on the head set side. 

Hope this will help.
