I have two monitors here at work, a laptop one and an external one. On the laptop I can't see any difference, on the external I really can.You_Too said:
Either way, the eye can have a hard time seeing a difference between shades of white in a picture. Look here:
This picture is divided into 4 squares, the upper left being tinted red, upper right green, lower left blue and lower right pure white. I bet on some monitors it's even impossible to see the difference because of the monitor itself.
Note to self: stop using Photoshop on the laptop screen.
