It sounds crazy and I laughed when a good friend's dad asked me, but...
He is a Vietnam vet (huey helicopter pilot) who loves playing simulators. He has a pretty killer PC I built him and hooked up to his 55" TV.
He asked me about adding two additional TVs to the side so he could get "surround" display and if a mount existed to put a panel in the center and one to the left/right.
I know such things exist for PC monitors, but is there a behemoth that can support such a setup for large (although relatively light LED) TVs?
