would 9 meter dvi-dvi cable work?
'Suck It and See' has to be the motto with DVI - there's no guarantee any DVI cable will work at that distance in all installations.
We have BetterCables 9m DVI-D Display Magic cables on offer in the Cable PowerBuy section of the Forums.
See http://www.avforums.com/forums/showthread.php?t=185961 - the cables are supplied on a Sale or Return basis.
i'll probably try making one, using standard 1.8 meter as basis
DIY and DVI don't mix. Bettervables DVI would be my first choice if you need 9m, with DIY you haven't a hope at that distance.
Nic - there must be instructions somewhere on the web for splicing 10 x CAT5 cables to form a low cost DVI cable
tried it mate, it doesn't work You need that Gorilla bar....
Without getting flamed - Monster cable do a 12 metre DVI cable but not sure of the quality over that length.
From what I have heard on the various forums (or are the fora). over about 7 metres you tend to get signal drop out.
Lindy SLD and Profigold cables work fine over these lengths, in fact the Lindy now goes to 25m albeit with limited resolution over 20m and we've never had any disappointment with them.
Results of weekend tests:
no more than 4.3 meters (used noname 1.8meter dvi>dvi cable as basis and noname cable to lengthen it)
quality cable probably would add meter or two, but it still wont be enough

tested with philips 9976 tv and samsung 720T monitor
I believe the cut and splice will snooker you - no matter what cable you use.
You have three options:
01. A decent quality 9m or longer copper cable; which works at the resolutions you require. We only install/supply cables that are tested at 1080P and above.
02. A fibre optic DVI cable - we have used these at 20m and further where copper cables didn't work.
03. A DVI extender - these are active signal boosters; they came in various specs to drive differing cable lengths; you can run DVI over a few KM if you want using one of these.
Just buy the better cables, I believe it will work for you in this situation. As you have found out all is not what it seems re DVI and a 'knowledge' is also needed to get past 5m. I have seen 15m work with one cable where 5m won't work with another, lots of factors involved here inc the chipset use, interference, the cable and the resolution it is used at (or more accurately the bandwidth also taking in freq).
I'm using a 15m Lindy with no probs but don't doubt it may not be OK for all situations...PJ
i'll probalby get some quality premade cable and do some testing
