Most of the LCD and Plasma TVs these days have inputs ( db 15 connector ). If you use eg M$ on a desktop with an AGP card with 2 outputs, use extended desktop to output to 2 screen and a splitter to output to 4. Or you may just get a 4 port AGP card that will handle this. ( This concept is similar to creating a Video Wall ). The entire 4 screens will appear as one and you can display the grahps accordingly. A splitter will create 4 views of the same output.

On creating RF channels, you must first create 10 outputs with the separate graph. each output will deliver AV signals. Then use RF modulators to convert the AV signal to RF channels over the same co-axial cable. The RF modulator allows channel selection and each TV can be tuned. This is called MATV and common concept in hotels, apartments etc. Availability of modulators is from any supplier who does installations of Sat dish etc.
