Re: DRIVER NEEDED: ViewSonic VG2230wm (Windows XP Professional) [PCI / ISA]
ALL LCD monitors built in the last 2-3 years are plug and play in Windows XP. This monitor is no exception.
If you are having a problem, it probably your Video & Graphics adapter rather than the monitor.
Check in Device Manager, under Monitors... does it say "Play and Play"? If so then that is correct.
