That's kind of funny Sean, I tried the same thing with absolutely NO change.
Wished I would have a bit of your Irish luck.
Got a Samsung LCD 19" widescreen for Christmas. Wasn't overly impressed with the text "crispness", so I ordered up a new videocard with the DVI out. Hooked everything up, loaded the new drivers and, voila! Looks exactly the same.
Inquiring about, the guy at Past Shop Worst Buy said I should order the Monster Cryogenic DVI cable, and do a 247 hour break-in. He said the "imaging" will be incredible, and that subtle nuances would be revealed with proper cables.
Yep, that will fix my problem.
