I've noticed a lot of graphics cards say that they can support multi-screen display, but it is always worded as "can support up to 3 30" monitors at 1920 X 1200" or whatever the case may be. I didn't think that the size of the screen made a huge difference, as long as the resolution was the same. At work we need to display network metrics on two 50" TV's and then have an administrator be able to work from the computer monitor. What graphics cards are able to support this in a Dell Precision T3500 Tower Computer Workstation??
