New monitor for NT machine

I've recently put a new Viewsonic E771 monitor on a Windows NT 4.0 machine (not a server, but a workstation). The monitor display looks a little fuzzy. I've gone into Display Properties and tried a few different settings, but nothing has cleared up the screen so far. I went to Viewsonic's website and downloaded drivers, but they don't support NT. Any ideas?

Well nevermind... I changed the refresh rate to 60 MHz, and the person using the computer said it looked better (fixed) to her. I thought it still looked somewhat fuzzy, but if she likes it...
