Hello,

I own a MacBook Air M1 and a LG UltraFine 32UN880-B which supports HDR.

If I turn online High Conrad Image in the Settings of the LG Monitor in Big Sur OS Settings the Monitor recognizes a HDR input, which is good.
I really love the image quality on HDR Movie/Videos BUT I think the normal surface/images have a grey veil and are not that colorful like with the default vivid image presetting on the monitor profiles...

Is there a known Bug or so with Big Sur?

Thank you guys in advance!

Best regards

It is bug for sure, but i'm not sure if it's on the apple side. I just disabled HDR myself because of washed out colors.

This is true on Windows PC. I don't believe it is a bug. I have no problem with external secondary 4K monitor. It's just a problem on both PC and Mac as primary monitor for me.

Yes, this is very unfortunate. Apple seems to display SDR to HDR directly which makes it unusable. They need to convert the SDR colours, luminosity or whatever to HDR.

Right. How hard would that be? I guess the problem may be that the OS doesn't know what windows are using HDR so they don't know what parts of the display need to be converted from SDR? In that case they can have the user select what apps / windows / websites use HDR.

The OS already knows, and it works well on the Apple XDR monitor and with many HDR monitors. So the issue is somewhere else.

Which HDR monitors other than the XDR don't the graying issue? Are they true HDR?

Windows has settings to adjust for this issue but on Windows it is true that not every monitor needs that adjusted.
