In response to turbocad6's concerns, the most likely bit to fail is the sensor, rather than the computer. At least the computer(if sensible programmed) will let you know that there is a fault. Most electronic interfaces will include a "sensor fault" detection, and the program should indicate this state.

I just love necrolyte's setup. Now, if it could run on Linux .......... Where are you on it now ?. If there is anything I am likely to be able to do to help, in return for getting access to what you have done, let me know. I am an electronics engineer, with quite a few years on microcontrollers.

For "splitting" displays, there are systems used for "video wall" setups which do that. What the technology is, I don't know.
