I just got a 23" Philips 230E monitor home and have hooked it up to my 15" mac book pro. I'm not sure whats going on or how to fix it but it's appearing fuzzy and flickers (pixels seem to be moving) a little in the standard resolution of 1920x1080. If I change the resolution to the next setting 1680x1050 the pixels don't move and but the screen still doesn't look crisp. I don't have any options to change the refresh rate either. Just wondering if anyone else has had a similar problem with external monitor's and how I should go about fixing it... thanks!
