Ok, I am running a 4k Amcrest camera at 3840x2160 on a 1920x1080 monitor. Because I am running a 4k camera I went and bought a 4k Samsung monitor (the video card supports 4K) After hooking up the 4k monitor there is no difference between the two monitors! How can that be? First monitor is a Samsung 1920x1080. The new Samsung monitor is 3840x2160. the video quality is the same!
