A:AnswerScreen detail is great on this monitor. I compared this Dell to around 20 others & the overall clarity won & the one out of my box was just as good as the one at the store.
A:AnswerThe game mode HDR or the movie mode HDR the picture is already calibrated so you can't make adjustments to it but you don't have to. Even if what your using isn't compatible with HDR it still looks beautiful.
A:AnswerYour Surface pro is likely outputting the audio signal to the monitor as well. The monitor doesn't appear to have speakers, but it does have an audio output. You can connect an external speaker to the audio output, or you should be able to change your settings on your surface pro to output the audio through the surface pro speakers instead of via the HDMI.
