<p>Generally VGA is limited to 100', DVI about 35', if there is power along the line, you can run a VGA amplifier, but you want that as close to half way along the line as possible. Svideo supposedly can go 150' but it depends on the signal strength being put out by the card, more importantly though, some cards may only put out a duplicate signal to what they put out over VGA. Let me know how it works though, I am moving the projector, and the card in the computer I want to use has an svideo output....</p><p> </p><p> </p>
