I have a recently purchased Acer Predator XB281HK running in 4K from a 1080ti
When I change an internal camera view or even move within the current view, the brightness increases.
If I select an outside camera and then back to interior, it reverts to normal.
I established yesterday that this doesn't occur if HDR is unticked.
I don't have this issue with my HP LP2475w monitor.
Any thoughts?
Additional edit: The problem doesn't occur in V5 which I've installed this morning so I'm guessing there might be some setting responsible?
