I just had a chance to install the new s2721dgf, looks like there is no dead pixels. Is there any protecting cover etc on the screen itself? It looks like there is 2 gray dots on the edge of the monitor (like something is stuck on the screen it but there is airgaps under it, eg. screen protecting cover) so I can't be sure if there is something to be peeled off or not. And one last thing, the sides of the screen has shades, like it's grayish on the edges (all 4 edges), is that expected?
bonus question: how do you change the RGB settings? My preset mode is set to Standard, and it doesn't let me change any RGB setting. If I choose Custom Color Preset mode, then there is Gain, Offset, Hue, Saturation options but not sure which one to change to match recommended settings.
