I'm trying to figure out what is happening to why this Dell Precision T3600 workstation with two FirePro W5000 video cards is not displaying correctly.
This is a 4 monitor setup:
Monitors 1 and 4 are displaying correctly. However monitors 2 and 3 both start splitting screen at any resolution above 1920x1080. Same monitor will display same image on both halfs of the screen.
The same monitor setup with same resolutions was used with older workstation with NVIDIA GeForce 9500GT and ATI FireGL V3400 cards.
I've tried last 3 driver versions currently on 13.152.4, however effect is always the same - video on high resolution greyscale monitors is split in half.
OS is Windows 7 64bit
