Intel HD730 and 750 gives artifacts with Netflix 4K + HDR

Situation

Okay, I have two Intel different Intel 11th gen systems. I have installed Windows 10, the Netflix app, the latest drivers (30.0.100.9955) and the HVEC codec from Microsoft (Link to Microsoft store ).

 

When playing 4K HDR content like:

  • 6 underground
  • Squid game

Then all kind of black and white artifacts pop-up on both systems.

 

Tested

  • Used two different Intel 11th gen systems
  • Used direct HDMI to LG TV or with a receiver in between
  • Tried to lower ram speed (2933MHz to 2133MHz) to test for memory issues
  • Tried different HDMI cables
  • Happens ONLY using Netflix
  • Tried to use Netflix in Microsoft Edge browser, which results in the same incident
  • Updated firmware of LG TV to latest state
  • Updated Bios of both motherboards
  • HDR is switched ON and OFF
  • Problem is highly related to HVEC decoding because the problem disappears when switching back to full HD
  • Issue seems to be related to other topic on forum 
  • Tested this issue with other Intel system from friend (also 11th gen) and same problem appears

 

Suspect

I suspect that there is a decoding issue with the drivers or somehow an incompatibility with Netflix 4K. If you need more information, I will provide further details.
