Grainy dark areas in HDR?

Development Rendering
1

Hi everyone!

I just got an HDR monitor and enabled everything - so far so good, everything seems to work fine.

When i open my UE4 project i notice everything looks a little different (better? brighter?)
But in dark areas i get this weird grain (looks like film noise from the PostProcessing volume)
What could be wrong here? When i drag the viewer onto my other screen (no HDR) it disappears and everything look like before.

I’m super new to HDR and can’t find a lot on how to use it in UE4.
Are there any good tutorials / documentation etc?
How do i color grade now? How to check if HDR + LDR looks good?

Hope someone can point me in the right direction!
Thanks in advance!

I wonder if the grain could be because UE shows the view in LDR and the monitor is “emulating” HDR.
But how to switch on HDR in the editor then…?

looks like not many people are into HDR :slight_smile:
