vga cable for LCD

plan on hooking up my new 40 samsung LCD to a computer.
however they will occupy different ends of the living room.
Obviously i will need a long cable.
do i go for a standard vga cable
a high integrity vga cable twice as expensive
an svga cable with audio?

i just don't know...... needs to be about 10 m

 

I just got a Samsung 27" hdtv yesterday and i am also wanting to connect up my Samsung to the Computer.
What effect would the long cable have on the signal recieved by the Samsung?
I thought that a D-sub cable is needed? and also a Stereo audio cable?
Where can I get these cables from?
Ebay has the cables but only 2m cables - I need at least 5m.
By the way the Samsung gives a fantastic picture.

 

the 40 inch has a vga socket
went to currys and they suggested a high integrity cable... vga if it was going to be longer than 2m
the cable itself was only 1.8m
i guess one with audio cable would be usefull. otherwise its surround via the computer 5.1. just want to get the best result..
to complicate it my video card supports HD ATI Radeon X800 GT (SE) 256MB GDDR3 VIVO All-in-Wonder (AGP) - White Box (GX-012-AT) "Transfer high-definition component video output via a YPrPb adapter "
see http://www.overclockers.co.uk/acatalog/ATI_Accessories.html

but i dont have the adaptor ?

 

we dont play games or anything, but we just display joe average windows apps. (desktop, word, presentations etc...)

and we use these

thats a 40" sammy lcd to pc.

for sound, we just use line to line. again, a belkin 5m line cable from ebuyer.
