It said PF775 in the display properties so I figured it was all set but, no refresh rates. I then installed the monitor drivers off the CD that came with it and rebooted with no change. I then went to device manager and clicked on change driver, Search for better driver, win98se asked for the viewsonic CD and after trying just about every folder FINALLY!! it loaded a driver. Now the refresh rates are listed and the display properties show the monitor as Viewsonic PF775. What a pain in the ass!!!! By the way, nothing listed in the manual about loading drivers. Time for a Beer!!
