I have a Dell Precision 5810 desktop and I have a W5100 workstation card. The IT guys setup my machine with 4 display port to DVI adapters going to 4 Dell P190S monitors. No matter what configuration I try, only 3 monitors are enabled. The 4th monitor is always disabled in CCC. I tried various configurations and I know the monitor works and the DVI ports are working - with only the 1st 3 monitors connected. The software version I am using is 14.502.1019 released on 4/8/2015. Any ideas?
