Hi, i'm facing a strange issue with a 1070 graphics card and would like to know if someone else had a similar problem.

The card is working fine but after the system has loaded the driver, the video output through HDMI port stop working, but if I plug into DP or DVI it works just fine.

This means that the GPU is faulty or might be something else?

Thanks in advance!

Is max resolution of attached monitor 1920x1080 or higher? Try another if possible.
(I have a 2560x1440p monitor that fails to display on amd cards over hdmi after driver load on linux, but dvi dual link and DP works fine. It is old and has "incorrect"/"problematic" EDID)

Also check that vbios info about connectors in GPU-z corresponds to physically present.

Thank you, i'll have a better look soon.

PS: I've tested at a 1280x1020, 1080p and 2k monitor, and didn't worked, but didn't tried to rewrite bios.

I've flashed a new bios and the HDMI now works again.. i've bought it as a faulty card and it had a strange issue before, and sice the card was working on DP and DVI, bios was the last of my thoughts. Thank you!
