New Acer SB220Q monitor screen yellowish-gray not white
Compared to my $279 Lenovo ThinkVision monitor the screen on the SB220Q is yellowish or off-white when the background is supposed to be white. I tried to alleviate it using the manual screen adjustment buttons on the monitor and by using Windows Color Management with no success. Night Lite is OFF. I also tried adjusting the monitor image using the Nvidia control manual with no success. My desktop has a high end video card: Geforce GTX 1080.
Looking at the pics on Amazon from other buyers they all look quite similar. The screens are not pure white but off-white or yellowish. Some buyers have also complained about the issue.
Being this is an $89 monitor, is this normal for such a low-end model? Two reviewers said the monitors bought last year weren't so bad, but the ones they bought recently were yellowish.
