Hello, I was shopping for a longer than 6' VGA cable so I can my PJ furthur from my computer and was looking at 15' and 25' cables. The 25' one is actually cheaper, but I am worried I might lose brightness/quality in the picture with a longer cable... will this make a difference? The 25' one would probobly more handy for other unforseeable future needs, but I'll get the 15' one if there will be a quality loss due to the distance.
Thanks

I googled it and from what I could tell, it's fairly easy to lose quality when in 1024x768 or better.with a long run of cheap cable. They do make good quality cable that can be run up to 250 ft w/ little loss. They're a bit more $$, but I would imagine worth it to get your setup the way you want it.

Looks like basically the same thing as the other, at a much nicer price. For $6.00, you can't really go wrong, if you hop on it, let us know how it works!
Actually, after shipping it was $15, but still a much better price. I'll be sure to let you guys know how it works.

The 10 metre (32.8') VGA cable I bought is thicker than the standard length cable.
I first made my own 5-metre extension using cat5, but the quality was poor.

Many so called VGA cables are very poor. The important thing is for it to have individual 75 ohm coax cables for the R G & B signals. The 25 ft cable you showed does indeed claim individual coax's.
Another way is to use break-outs and run these 3 signals along proper video coax. The sync signals are happy with almost any cable.
Your video card can affect things too. I've come across some early card that were not true 75 ohm impedance, but I think most modern cards are true 75 ohm, so it shouldn't be a problem.

I got the cable in the mail and it works great. I havnt had any problems with it so if you find something similar, don't worry about it. They work fine!

This makes sense to me. I am planing to make about a 30' or so run above my ceiling and I am considering using 3 separate 75 ohm coaxial and a 4 conductor alarm style wire.
Would this setup perform with decent quality? Should the coaxial be separated if possible (or no diffrence) and the sync wired I have both shielded and non-shielded wire I could use? I probably will use shielded to help prevent interference to anything else.
Is this a quality low cost idea?
I have plenty of the cable to work with just be a bit tougher for me at the connectors.
PS. I wouldn't really mine dropping a few bucks for a pre-made VGA. I already seem to be hung up making a cable/adapter due to the 25 pin connector on my Proxima unit.
