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?
Please forgive me if you have tried out these basic steps but they may be of some help.
If none of this helps or you have already tried it before, I suggest testing with another DVI cable, or if possible with a different monitor or even notebook. Try to determine if the problem follows the external monitor, the DVI cable, APR or notebook.
Please let me know what you find out.
