Hey does anyone know a way to use a video splitter to get the screens not to mirror the source, but project different images? Seems unlikely, but I thought I'd ask if anyone knows a trick...

Also, is there a cheaper device than the Matorx Triple Head that will let me display different images on multiple screens?

Actually there is no "trick". Depending on the needs you can create multiple rendering contexts or spread a single output across multiple screens.

The only thing that might be cheaper is if you are using Display port, or perhaps Thunderbolt and it lets you run multiple outputs by using a hub from a single output.

That said, the Matrox units are nice because in Max you deal with them as a single output/single render context. If you use a hub and create multiple displays, you have to deal with multiple render contexts by sharing textures or other methods if you want to span screens or move amongst them.

That brings up the question, the new Imacs and Mac minis have two thunderbolt ports... has anybody done any multiscreening using that?

(gonna play tonight and see) I have a Mac mini at the haus w two display ports and hdmi out

curious in particular if they show up as one external display or two?

Yes, you can use the two minidisplay ports to output multiple render contexts on newer macs!

All a video splitter allows you to do is display the same image on mulitple monitors. If you need to display multiple images on monitors you will need mulitple video cards. I have used KVMSwitchTech's HDMI Splitter solutions in the past with great success.
