Sounds as if you need multiple graphics cards or cards with multiple GPU (cards that have 2 or 4 monitor (DVI/VGA) ports). Mullard Electronics (http://www.mullard.co.ke/index.php/contact-us) used to have these.

Subject: [Skunkworks] PC to TV video splitters

Hi people,
I have an application installed on a PC which generates about 10 graphs of real time data, I would like to output these graphs to about 4 sony bravia TVs. My preliminary investigations indicate that a video splitter would do that. I have never used one before, any skunks with more details? Any local suppliers?

What if I wanted to have the 10 graphs be like kawaida TV channels so that I can tell users something like; "Switch to channel 5 to see report X", any leads on I can do that?

Thanks!
