I have a new Latitude E Series, Win 7 Pro, x64, with an e-Port Plus port replicator, and an older ViewSonic VG2030wm monitor. My previous Dell Latitude setup performed fine with a DVI cable, but I cannot seem to get a DVI signal out of the new system. I've resorted to a VGA cable, but I seem to now have either a bad VGA cable or VGA connector on the monitor. I get a flickering screen on occasion, turning to a blue/green background. I can wiggle the cable where it goes into the monitor and the picture will correct to normal.
I would prefer to use the DVI cable. Any troubleshooting tips on the DVI signal from the e-Port?
