Could anyone tell me the maximum recommended length of a VGA cable?
Thanks,Brian Goldsmith.

No such animal. Depends on the quality of the cable and whats driving it.

How long do you need? I've run them to 15 metres before but you do start to
get degradation in quality and ghosting.

**** Michael,about seven metres so I may be lucky.
Many thanks,Brian Goldsmith.

yeah, 7m with cheap cable wont be a problem


If you had a long distance ,you could go for low capacitance , high
bandwidth cable...

Cheap as in the standard sort of cable that comes out the back of a monitor.
If you get the really cheap stuff that is not much thicker than a keyboard
lead then you will get ghosting in 1 metre.

dont expect a decent picture if you buy cheap thin rubbish without the
filter on atleast one end.

I've put 10m extensions onto monitors used for critical post-production
work - they were thickish cables with a lump on one end - they didn't cost
much at all - about $30-$40 and there was no discernable ghosting running at
1280x1024 @ 85Hz.

if you wanted hundreds of meters you could use cat 5

thats what id use if i ever had to run a signal where quality was
important over a distance of over a metre or 2. Id use a 15 pin to 5
bnc adaptor and run rg6 coax from each bnc to the corresponding bnc
on my monitor. I was going to do that for my 2 meter connection to my
second monitor actually, but I could only get a dvi to 15 pin
connector, not dvi to 5 bnc, and introducing another adaptor would
sort of defeat the whole purpose of the thing, to get good clarity
video :)

I got some from the local computer dealer I was using at the time
(www.cougar.com.au) and I picked up some others of similar quality and price
from Sabre Industries (http://www.sicomputerproducts.com.au/) who have a
local shopfront.

They're pretty generic - I imagine your local, decently sized supplier has
similar. Just avoid the thin grey ones (all the ones I got were black and
about 8-10mm thick). Obviously you have to get the right combination of
gender to match your monitor (some have a permanent lead, most of the ones I
was dealing with - Sony 21" - had a choice of BNC & DB15 sockets on the
monitor).

The outside coating obviously doesn't make any difference but the low
quality cables tend to have a flat surface where the better quality cables,
um, don't.

Something like Belden 7796 would allow you to go a few hundred metres.
Belden 7789 maybe 100 metres
(all depending on bandwidth of course)

As long as you use active baluns, or only wanted limited bandwidth
