Windows XP/2000 and LCD Flat Sceen

Has anyone had problems with XP/2000 booting for the first time after the install on a LCD flat screen. I can boot after setup on an older CRT and then after shutting back down and changing to the LCD it works. The only thing i can think of the the inital video settings within the OS. i have tried to boot into safe mode and had the same problem. Any suggestions?
