My Windows XP computer stopped displaying Digital input but by connecting a cable connection for Analog the screen worked fine. Thinking that the video card likely had failed in it's digital mode, I bought and installed a replacment card ( EVGA 8400 PCI Express 2.0) Updated the drivers but this also did not display a digital signal. Thinking then that the digital cable must be the culprit, I bought a new digital cable. Same situation, no digital picture. The only thing left is the Samsung SyncMaster 191T flat screenmonitor. Am I missing some other possibility here?
Failure was instantaneous. Worked with digital signal for years. Completely failed while in use.
