VGA to RGBHV and RGBHV to VGA back

diren · 24th December 2003, 07:40 AM

Hello All,

I have a projector in my room on the ceiling and I used it to watch DVD over RCA cables. Now I want to use this projector for my computer output. The problem is I only have 6 pairs of RCA cables placed from the place I placed my computer to the projector.

What I want to know, is if it is possible to convert 15 pin VGA output of the computer to RGBHV (by just cables without electronic devices) and carry the signal with RCA cables to the projector and convert it back to 15 pin VGA (by just cables without electronic devices again) and have high resolution output.

Togive some other details,
- my projector is Panasonic LC75U
- The length of the RCA cables is approximately 9 meters (27 feet).

Thank you all in advance,

Ozan Diren

Diren.

You need to find the pinout of the VGA connector and locate the correct signals and grounds. You then build an adaptor with some low capacatance 75ohm cables.

Um, the cable does exist that converts 15-pin DSUB to RGBHV. Should be able to find it at most computer stores. You'll need one of those plus 5 BNC-RCA adaptors which are slightly harder t ofind. From that you can run them to your projector (and convert them back to BNC). The only problem you'll probably have as mentioned is that the BNC wants 75-Ohm cables and the RCA is something lower.
