Brightness drop in HDR !!

Hello. We're not aware of any issues with this. Have you tried swapping out your HDMI cable? Make sure it's a premium cable. If you're using the one your console came with, that's fine. It would be good to try another though if so just to see if that helps. Otherwise, it's possible there is a setting on your TV causing this.

Did you try a different HDMI cable or changing video settings on your TV? We're not aware of any issues with HDR currently.
