Hello,

I recently bought the Gigabyte RX 5700 XT GAMING OC.
I had some driver issues after inserting it into my PC which is to be expected from AMD, but I managed to get everything working after all.
There is one more issue left, that I can't find a solution for.
The HDMI port doesn't seem to work correctly, I can't get a signal on my TV.
Both my monitor and my TV worked with my GTX 970 and with onboard graphics but right after installing the driver I couldn't get a signal anymore after POST.
I am able to enter the BIOS however but the signal is lost during boot.
If I connect my TV when I am logged in to Windows sometimes the TV has a signal for a split second and then it goes black again.
After my new monitor with Displayport arrived I thought it was just a problem with my old monitor but now I experience the same issue on my TV with all of my HDMI cables.

So it seems to be a driver related problem or maybe defective hardware. I searched for AMD GPU users with the same issues, most ended up buying a RTX 2070 Super apparently.

Does anybody know what to do?
I'm kind of stuck here, thinking about returning the card as well

Windows 10 Pro (Clean Install after removing the old GPU), i7 4790K @4,6 Ghz, Gigabyte RX 5700 XT GAMING OC, updated BIOS
