Refresh rate is only an issue with CRT's as LCD's don't refresh the screen per se, they just update the pixel when it should change and it's constant otherwise. CRT's only briefly illuminate the pixels and do so at the refresh rate (IE at 60Hz each pixel is illuminated 60 times a second). The issue with LCD's and refresh rate is in how quickly the screen will be updated. At a 60Hz refresh rate pixels will only be updated every 60th of a second as teh computer is only sending the screen updates 60 times a second, higher refresh rates allow quicker screen updates which is an issue for gamers running at high fps rates. There's essentially no reason to ever run an LCD at anything other than 60Hz if you aren't running an application that requires high fps rates. -- M.
