Help, I have installed the Ati 7500, and windows just installs two default monitors, but doesen`t find and install my RCA mm61110 monitor. The monitor is plug and play and used to work fine, now Windows won`t detect it. When I delete the two default monitors in the device manger, Windows just reinstalls them at reboot. I tried the Sony DWM-900, but would rather stick with the plug and play RCA monitor. If anyone can help me slove this problem I ould be greatful.
