I use mine on gamma 4.
I started to notice a change in gamma / colours from top to bottom, 1st noticed on the battlelog window (the white background varies in whiteness!). The blue background on this page changes quite a bit too!
I know TN panels are not great but how about a comparison.
These tests show it up quite well - http://www.lagom.nl/lcd-test/viewing_angle.php
wow, that's really bad. I have the samsung S23a700d, it's a TN monitor as well, but the view angles are much better than that. That would really be annoying for me. Is it faulty I wonder? People seem to be pretty happy with the benq overall.

, should be here on Saturday.
