Agony Of Computer Hardware

What is the point of making a 3 output video card if only 2 of the outputs work simultaneously. I know why to drive the computer repair and IT support individuals bat shit crazy. which is were i am headed. Racking my brain for hours on end trying to figure out the issue to only find out it is not supported with 3 monitors at once. Now i have to find another way to get the issue fix and the computer to run 3 monitors.
