VGA Wall Plate wiring
Hi,
I'm installing some audio & video cables in the walls;
I have 2 plates with audio & video connectors, one of the ports is for vga;
One plate will be in the ceiling to connect a projector to, the other will
be in the wall to plug the laptop into.
They look like this:

Which type of cable do I need to connect the VGA connector block to?
and which wires would then go into which terminals?
Any help gratefully appreciated!
Thanks

You could try some of this, http://www.maplin.co.uk/20-way-overa...cart-cable-290
It is Scart cable and will have more than enough individual cores for what you need but it is shielded which is important. Alternatively you could buy a long VGA cable and chop the ends off and use that.
I see that it's got HDMI as well, aren't you going to use that instead?

Thank you Neil, will go and investigate that cable at maplins;
what I don't know yet is: -whether we use VGA or scart cable, does it matter which wires go into which blocks? as long as they're consistent each end, obviously...
We will be wiring up the HDMI ports for the future, unfortunately the projector that we currently own doesn't use it, so we need to use the VGA ports for now.
Thanks again!

There is another way.
If you get hold of a length of shielded cat 5 cable and connect pins 1,2,3,6,7,8,13&14 at each end and then using the single uninsulated wire in the cable connect it to pin 10. This should be good for up to 50ft. Nice & cheap and works. If you don't use shielded cable of any type you will get ghosting.

Thanks so much Neil, we will investigate that and let you know how it turns out.
The latest puzzle is that we realise there's possibly not enough room behind the plate to plug in all the cables.. \
Never a dull moment!
Thanks again

Just as a matter of interest, I received some RJ45 to VGA adaptors yesterday and I'm now feeding a display from upstairs to downstairs via unshielded cat5 with a cable length of approx 12m with a coupler in the middle as a test and it works perfectly.

Chris,
I used these http://www.ebay.co.uk/itm/ws/eBayISA...:X:AAQ:GB:1123
They arrived within a couple of days. When I need more I'll be ordering the same again.

Ok this is done a lot in schools and colleges. My experience is that CAT5 type fail or get interference and the only effective solution is VGA cable. CPC farnell sell the kits that are used in schools etc. they are not a bad price and make installation easier. I have done this in my large kitchen to connect TV to amp, sound and security system it works well.
