Pink Pixelation and banding in HDR Videos on my HDR TV (Even the preview video included in recent insiders build). Facing this on stable build also. I'm on latest Insider build, still the HDR playback isn't fixed since the Fall creators stable update. I experience all types pink pixelation on ground, sky and water which are moderately bright areas in a HDR video. TV completely supports HDR and it's a 10 bit panel. There's a lot of banding in sky. Tried various custom settings in Nvidia panel too but that doesn't help. In Netflix, pink moving pixilation goes on the face of Actors. For gods sake, demo video inbuilt for HDR in windows 10 also looks awful with banding and pink moving pixels in sky. Attached some screenshots and a video for reference. ***I played the same files on TV natively and it looks gorgeous with true HDR.

Yes, tried with MPC(madVR add on), PowerDVD 17, Default Movies & TV player. All players exhibit the same issue as demonstrated in the above video link. Only player which mitigates this is MPC with madVR add on and Windows HDR set to OFF as MPC is capable
of applying its own HDR settings when windows HDR is off.

Hi,

First make sure you have the newest Nvidia drivers installed for your Operating System.

Have you tried to reproduce this issue with another computer?

There has been a lot of cases where HDR has been a bit unstable or behaving oddly, and this has been due to a bad HDMI cable or a HDMI cable not supporting the newer HDMI versions.

A quick and easy way would be to change the HDMI cable, make sure it supports High Speed (HDR).

Kind regards,

Leon
