video multiplexer

I'm not sure if this is the right term for it. Searching with that term did
not find what I was looking for. I have seen them, but at lower resolutions
than what I am hunting for right now.

What I want to do is have 4 separate computers displayed simultaneously on a
single large LCD monitor, in a 2x2 grid. For a 1920x1200 monitor, that would
mean each computer can operate at 960x600 to get a 1-for-1 pixel display in
its portion (otherwise it would have to be scaled). For a 2560x1600 monitor,
that would be 1280x800 each. For 1600x1200 that would be 800x600 each.

Have these kinds of things disappeared already?

Try "compositor". SGI appears to still sell one,
and that's what the final video box was called in
hp's Scalable Visualization product. I no longer recall
who hp got theirs from.

Crafting a search to avoid other forms of
compostion can be tricky.

Matrox might be worth a look (and I didn't).

I am trying to accomplish the same thing. Have you been able to find a solution to this.

My final display is going to a 2560 x 1600 monitor with DVI input.
