Hi there. I am working with two monitors. The first is a ViewSonic VX2250wm LED monitor, connected to the desktop (Lenovo ThinkCentre M90p) via a DVI (in monitor) to Displayport (Desktop) cable. The card is an Nvidia Geforce 310.
The second monitor is VGA.
Every so often, the ViewSonic's signal goes out. At first I thought it was the DVI/Displayport adaptor, but upon getting a new cable the problem persisted. I then assumed it was the latest Nvidia driver update, so I rolled back. The monitor's signal returned for a few days, but then eventually lost its signal again.
This process repeats every time I install an older driver: the monitor comes back, but eventually dies. I am trying to figure out what is the cause of this problem. AFAIK it cannot be the Displayport as the Geforce is compatible. I have concluded it must be the ViewSonic monitor.
Any help as to what may cause this loss of signal would be appreciated.
