I recently bought a Dell computer with a dual monitor display set up. I plugged everything in and seem to only get one monitor that works. the second monitors power button flashes as if it is on but the screen is just black. The computer acts as if both monitors are on and I can drag things to the second monitor, I just can't see them. The monitor that isn't working is a Samsung SyncMaster 943BT. I have been searching for hours on how to fix this. I tried a tech support website but they were going to charge me $130 USD to just look at it. If someone could help me that would be greatly appreciated!
