When giving my presentation my computer is too far from my projector for the supplied cable. What is the maximum cable length?

Using VGA cable (the cable with 15 pin "D"shaped plugs) the usual maximum figure is around 15 metres with a good quality cable. This however can vary somewhat depending on the cable quality and external conditions so it's as well to test before it becomes critical. If you experience problems then you may need a signal or distribution amplifier.

DVI is a little more limited. Cables up to 5-7 metres should work but anything longer may require a very good quality cable or boosting.
