HDMI not displaying - Intel ARC A770

So, needless to say I am pretty disappointed and frustrated that this is the experience with my first Intel product ever.

I usually game with multiple displays, one being a big TV so my wife can enjoy watching single player games. It's a 4K display, and it used to work just fine on my RX 480 using HDMI.

 

With this new card, windows recognizes the display as "MStar DEMO" but shows as no signal.

I've tried updating windows, have the current Intel graphics software updates, tried getting a brand new, HDMI 2.1 certified cable and still nothing. The intel graphics app closes anytime I try to tinker with display settings like GPU scaling as someone suggested so can't try that.

 

Whenever I plug in my old GPU, everything works. 

The new GPU has some software or driver issue. The port looks good with no damage. I tried all 4 HDMI ports on the TV.

What do I need to send to figure this out?

  1. Please specify the manufacturer and model of the TV.
  2. Please run edid-test.exe:

    This will create a file named "edid-test.txt" in the same folder. Please attach this TXT file here.
