I'm running four monitors off of a Dell workstation. Do not remember what card it is using, just that it has one output and a cable that splits it into four. All four monitors are a different size. The standard issue here is one monitor. Coming from the military I have learned to improvise. I first stuck a video card in a PC that did not kill the video on the motherboard. That caused another guy to get a dual monitor card for his PC. When he left I borrowed his card for three. I did not expect them to approve this workstation, the gods must have been happy that day. I find it handy using the different sizes. The biggest one is where the IDE resides. The widescreen is rotated 90 degrees and is good for displaying text files.
