ive just bought a samsung U28e590 4k monitor, and currently running it through my asus mars ROG gfx card, a dvi-hdmi cable on the gfx card to hdmi on the monitor and it works fine, or so i thought.
the resolution of 3840x2160 (is it?) is too high for the monitor so ive had to scale it down to 3686x2072 as i couldbr see around the edges like the task bar.
is this normal, did i do anything wrong ?
