From one of the support forums 2 seemed to give some improvement for me. requires going in to terminal "I have had the same issue.. Brand new Mac mini with new Philips 239C. Anyhoo, also tried all different cables and settings and nothing worked. Text still looked blurry, then I came across a post and this has helped so much! Unfortunately I don't have the link, but all you need to do: - Open a terminal - Type in: For medium font smoothing: defaults -currentHost write -globalDomain AppleFontSmoothing -int 2 killall Finder - Restart applications Replace the 2 in the command with 1 for slight and 3 for hard smoothing."
