Just tried those settings on tftcentral...
Made viewing black text on white background a massive improvement.
In fact was just about to add to the thread that the negative impressions were starting to come through with this screen, in that text was harder to read in terms of clarity than on my old Dell U3011, those settings have made a good difference, not perfect but my eyes aren't burning and squinting now.
(I will add that my eyesight isn't top notch, I'd imagine that for most people with good eyes, these settings would bring text and whatnot into line with being very good).
