Big whoop - get a hole saw/core drill and have at it. Better yet, drill
2 inches and cover the next set of connections you'll think of later all
in one hole.

Depends/Yes.

Well, that depends a lot upon you. If you feel the need to ask a
newsgroup about it, I'd guess probably not. A degree of competence at
soldering is required, and if you already possessed it, I doubt you'd be
asking...

You could solder new connectors to the wire but it might be easier to cut a
cable in the center, push one end through the hole, strip back the wires
and splice the corresponding colors together. Use insulated sleeving over
the soldered splices and a layer of tape over the wires.

You can but it is a pain. The RGB signal lines within the plug are coaxial
cables.
Soldering can be done but it will require patience. You might opt for a 15
pin
D sub that accepts crimp connectors.
There are devices available that can send the VGA as well as mouse, keyboard
and
audio over one or more CAT5 cables. Sometimes these devices use their own
specialty cable to interconnect the equipment.

I like your suggestion better than mine and it's typically what I would do.

So you think buying a connector and soldering all those pins is easier and
cheaper than backfilling the oversized hole with drywall mud, sanding and
painting. I don't and I have no trouble soldering.
Following the hole saw idea, save the plug of wall you drill out, carve a
notch to fit the cable then fit the plug back into the hole with a little
glue or drywall mud to smooth out the edge. A little paint and you are
done.
Another solution is to do it all behind the base molding. No paint, a quart
should cost only a bit more than a proper connector with a shroud and can be
used other places.

Yes. (I've done it.  )

Instead what I'd like to do is pass a narrow cable through, then
solder the connector on once it reaches the other side.
Is this advisable/possible?
It'd be more of a PITA than to make a hole big enough to pass the
connector and spackle around it.
One major caveat - I wouldn't recommend that wire. Every VGA cable I've
seen has red, blue, and green coax cables for the video. I have no idea
where you'd buy that in bulk, maybe Belden or Alpha or so.
And be careful of length - the VGA spec might call out a maximum length
becase of the frequencies involved.
Good Luck!
Rich

What usually happens after carrying out such a project is that it looks less
than acceptable, ie. ugly! When you see a thick VGA cable disappearing into a
wall at right angles you can't fail to think otherwise and you wish you had
thought of another way. And when you do find this method you have to fix that
wall, and even then it could still look ugly....
To avoid drilling any holes you could resort to a wireless VGA extender but my
thoughts are that the potential for interference from other electrical
appliances or apparatus is likely and the video quality may not be acceptable.
depending on your requirements.
http://www.engadget.com/2006/01/19/the-wireless-vga-extender-eliminates-some-other-wires-too/
My preference, but still using cable as the transmission media, is a VGA - Cat5
sender/receiver setup made by Gefen
http://www.gefen.com/kvm/product.jsp?prod_id=4448
Because the unit is capable of extending up to 150ft you could route the cable
via another route such as the ceiling space and/or external cavity brick walls
with good looking Cat5 wall plates at either end of the transmission cable. That
way you could put the distant VGA monitor in the most suitable location in the
room without having to worry about cable length and signal quality. It may not
be the cheapest method but it is probably the best and neatest in my opinion. |

Tony,
I agree with a couple of the others: learn some simple drywall repair
techniques. Cut as big a hole as you need, saving the piece you cut
out. When the wire is through, glue the cut-out piece back in,
slightly below the surface of the wall. Then, just fill in with
drywall mud, sanding and filling until it looks good. I say this with
40 years experience as a good solderer and a few weeks experience with
drywall repair. |
