What is that grid on the screen? Horizontal and vertical lines / squares...?
That tint looks quite bad, try changing the color temp preset, gamma etc. or change the RGB levels (lower green and red and leave blue at 100) use it for approx 100 hours and if the tint is still there I would return it.
I guess it's some optical effect introduced by my camera (moire or something like this). I can't see any lines or squares on the actual screen. Solid color patches (whites, greys) are actually a pleasure to look at - so silky and smooth. It's probably because the black interpixel grid which is typical for 1080p IPS panels is almost invisible here. Pixels are smaller so is distanance between them.
Jaggies and color halos around letters are also only visible on the photo.
I can't see any crosshatching patterns, not even a hint of it.
As for the tint I've tried almost everyting - can't get rid of it. It's really, really annoying when working with documents.
