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

The quality of your video will be affected with a long VGA cable, although they do make some heavily shielded VGA cables that can go quite a distance.

Serial cables can actually span quite a distance before signal loss.

If you used heavily shielded cables you should be fine

So as long as I get a good one that is shielded the video should be fine?  That's what I thought; my main concern is the serial cable and the touch screen response.

Thanks

The serial cable should go 20 feet without issues. A cat5 cable can go about 100 feet without enough loss to cause an issue, so 20 feet should not be a problem.

For the video could you not try some sort of video sender? Don't know if they make a VGA one though...

thought of that but wasn't sure of the quality and since I have to run a serial cable whats one more.

I have dealt with both very long extensions of Video signals and serial networking for over 20 years

Trust me if you get well shielded cables you will not have problems.
