Touch Screen performance with long VGA and serial cable??
squirrellydw:
Does anyone know if the performance of a touch screen will be affected if I use a long VGA and serial cable? My guess is it will be about 20 feet at the most. The reason I ask is I would like to mount my touch screen on the wall and have the case as small as possible and I could but the computer with my stereo. What do you guys think?
Thanks
sorry if this is in the wrong forum

RS232 is dual voltage and can be run a max of about 150 feet so it will be no problem. The VGA is very much dependant on signal quality for analog so use the best cable you can for extended runs. Projector and other units are quite often run on 10 to 20 meter cables for video presenations in auditoriums. So 30 to 60 feet is commonly done. 20 feet should be no problem.

RS232 is a serial cable. Hardly used any more. I have a 100 foot VGA cable run at an office to a plasma tv. Works fine.

cool thanks, I just measured and will need about 35 to 40 feet total. Any difference in using a VGA vs SVGA cable? Newegg has both
