There are two factors that greatly affect the image quality. One is the VGA driver - the display card. Many are designed to drive only short distances and do not perform well above 10 to 20 feet. The other is the cable itself. VGA is a high resolution video signal and demands a properly designed cable to carry it over a long distance. Many short VGA cables do not comply with the transmission standards for long distances. They work over a length of 5 feet or so but for long distance transmission, 75 ohm co-ax cable is needed for each of the red, green and blue signals.
Given a proper video driver in the display card, several hundred feet is possible if the right grade of video cable is used to carry the signal. This type of cable is not a standard product in most cases, so it will need to be made to order. Standard cables over 100 feet are rare.
The current maximum length for a serial cable is around 50 meters. Different cables have length limits with the maximum varying.
Cat 5/5e/6 cable has a maximum installed length of 100m, but that is a written standard, not an operational maximum.
100 Meters is the maximum segment length.
The maximum length for a parallel cable is 15 feet. The maximum length for USB is also 15 feet, but with powered hubs in between, you can stretch the distance to about 90 feet.
It depends on the quality of the cable used.
As per the A+ Guide to Hardware: pg. 395 The maximum cable length for a serial cable according to RS-232 standards is 50 feet.
You will have to get a VGA and RCA cable. You can connect the VGA cable from your laptop to a VGA/RCA adapter, and the RCA from the adapter to the projector.
The maximum length of a cat 5 e cable with out a repeater is 100meters
The maximum length for a printer cable is 1 thousand million metres.
The maximum recommended length for a UTP Cat5 cable is 100 metres
