I had exactly the same issues with a good quality 1.3a/c HDMI cable from a Radeon 5970 and 1920x1080p HDTV. All the Catalyst driver sets made no difference with HDMI, text was fuzzy looking, had a slight blur. I now use a good quality DVI-D cable, same 5970 and HDTV and games are much sharper looking and no more blur effect on text.im using a hdmi cable is this wise? using a 23 HD phillips screen.
Sounds like MLAA is on in the Catalyst Control Panel.
Had this identical prob, desktop fine, but blurry texts in windows mail. See if MLAA is enabled in the CCC and disable it as had been stated earlier
