Maximum Length: 16' with a standard cable, Up to 50' with a high quality cable. VGA is an analog signal and so as distance increases the quality will decrease. A lot of factors can determine the maximum cable length, but for low resolutions (up to 800x600) you can reach 100 feet and beyond without too much trouble. For mid-range resolutions of 1280x1024/1024x768 you can typically reach somewhere between 50 to 100 feet.
Definition - What does VGA Cable mean? A video graphics array (VGA) cable is a type of computer cable that carries visual display data from the CPU to the monitor. A complete VGA cable consists of a cable and a connector at each end, and the connectors are typically blue. A VGA cable is used primarily to link a computer to a display device. One end of the VGA cable is attached to the port in the graphics card on the computer motherboard, and the other to the port in the display device. When the computer is running, the video card transmits video display signals via the VGA cable, which are then displayed on the display device.
