setting up a matrox m9120 card and video wall

This wall is going in our Arctic exhibit, and if I deliver on promises it will look very good. The catch is I have to deliver on promises.

There are so many numbers in making this work optimally that it hurts my brain.

Screens are 1366x768
Card can drive 4 screens but can't drive the native resolution of 1366x768
Card can drive the screens at 1360x768 and the screens look good
Total screen resolution is 2720x1536
Video resolution is 1280x720
Total video resolution is 2560x1440
So what should the digital signage software drive things at? 2720x1536 or 2560x1440?
I can't get four streams of video to run in sync and I don't want to scale a single 1080p stream so that leaves me with building probably a 2560x1440 stream and having something somewhere along the way scale it. It's nasty.
