Rs232 serial video connections

 

Unregistered guest
My Optoma H31 came with a RS232 cable, one end of which plugs into the serial port of the computer, the other end of which plugs into a special port on the projector. Simply plugging in the cable does not seem to be sufficient, as the projector does not recognize any input from the source (the computer). This makes sense, as I wouldn't think that video information is constantly streaming to the serial port of the computer. The Optoma documentation says nothing about this cable in setup. Does anyhone know how this is supposed to work? Is there a driver or setting that must be adjusted to direct video signals to the serial port? Thanks for any info.

I have never heard of video running through a RS232 cable. Does your project have any other video inputs? VGA? If it did, I wouldn't even bother with this RS232.
