The new plasmas like NEC, Panasonic have an integrated Split-function for 2×2, 3×3…and so on.
So I think the easiest way should be a special prepared video (16:9 anamorph), for example done in Aftereffects, and let do the split in the plasmas.

First I would drop powerpoint. Create pictures and text in a compositing software like AfterFX.
Make a Composition 4800 x480 and render out the 4 splitscreens separately. Put this videos on https://www.alcorn.com/products/dvm4/index.html an you are done.
IMHO the easiest and cheapest way for 480px plasmas for a fixed installation.
Extra benefit: “The DVM4 may be controlled using RS-232 or Ethernet. Sophisticated play-listing and a Real Time Clock scheduler support extremely complex stand-alone operations.”
Do you think multibridge extreme will be shipped in June?
If not, which card should I use in conjunction with multibridge to get the same possibilities as Multibridge Extreme?
