a&w restaurant: I added to another monitor thinking it was the monitor and I am getting the same error digital input error. I am not sure what I have done wrong. Any suggestions would be greatly appreciated.|||Usually windows 7 32 bit and 64 bit actually recognizes an extra monitor whereas in XP, you have to use the clone setting in Display Advanced Graphics Application. Perhaps the bios setting is still set to onboard grahics display rather than PCI-E.
