Hi, I’ve got this monitor and have noticed significant differences in gamma when switching between HDMI 1.4 and 2.0 inputs. More specifically, gamma reaches absurdly low levels when using HDMI 2.0, resulting in an awfully washed out image. It’s far from perfect under HDMI 1.4 too, but it’s not as bad. Unfortunately, I don’t have a DP cable, so it’s impossible for me to run any tests with the DP input.
Have you noticed the same thing during your tests? Are gamma levels under DP the same as HDMI 2.0?
