I need to connect a Projector by a 40m length of cable. Would SVideo or Composite be better for this length of cable. I've read conflicting opinions when reading up.

Anyone run this length?
 
Yup, the projector has an available SVideo and composite connection. It is already connected to a PC. There are no other connections.
 
S-Video will be better than composite, but still **** over that distance. And good luck finding a 40m S-Video cable. :)


Best solution is to get a distribution amplifier.... or another projector.

Alternatively, why not get a KVM switch at the source and use the same PC connection?

That's my concern, yeah.

I'm needing to move away from running the DVDs from the PC, as I'm tired of explaining how to use the PC to do it. A standalone DVD player with a play button is much simpler. (It's for a church)

I was thinking perhaps wireless video?

Not sure of your budget, but I think you're headed for a world of hurt setting up a wireless system that'll be used by third parties.

How about a presentation switcher? Like this: http://www.extron.co.za/product/product.aspx?id=mls304sa

Not sure of the price, but it'll be a more robust solution.
 
I've got a 20m composite cable from my AV amp showing DSTV or DVD with my projector. I use it as a TV at home and there is no noticeable degradation. In this config I can view/inspect the screen from very close if I want. Double the cable length for a screen nobody gets too close to- i don't see a problem.

I had it made up by Linkqage in Paarden Eiland. They used fat 18 strand VGA cable and used 3 strands per terminal. Didn't cost much either. I went for composite because my AV amp doesn't do S-video. They will be able to put whatever connectors you want on it.

Is it shielded? Main problem with lengths that long isn't just the resistance, but the potential interference. Especially in an environment with, say, flourescent lighting.
 
I'm in the video business and we use decent co-axial cable up to 70m with no real issues at all. (video surveillance shops sell that cable too). Dont try and use audio co-axial cable - impedance mismatch.

If you need to go further we used VGA-LAN converters (about R500 a set TX AND RX) and then run cheap CAT5 cable for 300m.......no discernible degradation in signal.
 
AFAIK VGA cable is shielded. I don't get any interference from my flourescent lights, microwave, cars driving past, etc.

Best give Linkqage a call and tell then your application and concerns. When I got my cable I was concerned about quality degradation and they insisted it would be ok and said they would be happy to take it back if I wasn't satisfied.
 
the VGA <=> CAT5e converters are pretty sick, and would prob cost about the same anyway, and then you can then run shielded CAT5e. You could also run HDMI <=> CAT5e but I believe it costs abit more.
 
i have used a 60m RCA cable several times for a projector vid cam setup. Good quality cable with good connectors = no prob

Doesn't help the OP though. As he's only got one VGA input on the projector and it's being used.
