PG32UCDP Contrast option bug ?

[Aragonite]

I appeal to the owners of this screen ...

I don't know if there is a problem with the contrast setting ...

I have changed this option, I see no difference on the screen ...

Is it a firmware bug? or does my screen have a particular problem?

I specify that I updated the latest firmware: MCM103

Well, I just noticed the contrast change only works in SDR mode ...

But why is this option always enabled in HDR mode if it is useless?

Shouldn't it be grayed out?

I hope it will be possible to use it in HDR mode in a future update ...
