Ok so i just upgraded my monitor from a 24in Viewsonic to a 27inch viewsonic and all the text is either multicolored/fuzzy or both. res is set @ 1920x1080 i reinstalled all drivers for the video card and monitor, tried changing cables(i use the DVI) and still to no avail, cleartype is on and ive gone thru the process of adjusting it several times and blah. any ideas? Currently using W7 64b Radeon HD5670 VC.

What refresh rate are you running? Does the old monitor still work correctly? The new monitor may just be defective
