The maximum length of a VGA monitor cable is 100 feet. This is the maximum length that the cable can be without any signal degradation. If you need a longer cable, you can use a VGA extension cable. These cables are available in lengths up to 150 feet. However, you will need to use a VGA amplifier if you go this route.
The reason that the maximum length of a VGA monitor cable is only 100 feet is because of the way that the signal is transmitted. VGA uses a analog signal, which means that it is susceptible to interference. The longer the cable, the more likely it is that the signal will be degraded. This is why it is important to use a high quality VGA cable if you need a long cable. Otherwise, you may not be able to get the image quality that you want.
If you need a longer VGA cable than what is available, you can use a VGA extender. These devices convert the analog signal into a digital signal, which can then be transmitted over a longer distance. However, you will need to use a VGA amplifier with these devices. Otherwise, the image quality will be degraded. The maximum length of a VGA extender is 500 feet.
If you need a longer cable than what is available, you can use a VGA splitter. This will allow you to connect two monitors to the same computer. However, you will need to use a VGA amplifier with these devices. Otherwise, the image quality will be degraded. The maximum length of a VGA splitter is 500 feet.
If you need a longer cable than what is available, you can use a VGA switch. This will allow you to connect multiple computers to the same monitor. However, you will need to use a VGA amplifier with these devices. Otherwise, the image quality will be degraded. The maximum length of a VGA switch is 500 feet.
