I have a laptop with VGA video output, and I bought a simple adapter from VGA to DVI-D, and I am trying to connect a big monitor using Dual-Link DVI-D to the laptop.
When I do this, the laptop Windows Display GUI Detects the Big Monitor, identifies it correctly and identifies the maximum resolution to it. I can dual-display to both of them, and the cursor moves off of the small laptop screen and into the Big Monitor.
Except, nothing is actually displayed on the Big Monitor, it is black. When I disconnect the cable, it cycles RGB default screens, so I know the power is on to it.
What could be the problem?
