VGA switch

There are some cases when you have multiple sources of video signal and you have just one monitor to view them on. In such a case, instead of taking out cables and plugging others in the monitor, you can use something like a VGA switch. Some examples of using a VGA switch include sharing a projector among many computers, or using a single monitor for multiple personal computers. There are many things which can be done with the video signal of a VGA switch. You can control multiple servers from a single display device, you can cycle through the feed of video cameras if you don't need to supervise them all the time and so on. You can use all types of computers for this purpose, as long as they provide a VGA video signal which can be used by the switch. You can even use DVD players and VHS devices with a VGA switch. You will find VGA switches in many variants, some of them offering between 2 and 8 ports. If you want even a bigger distribution you can use the cascading method to connect a huge number of devices to the switch. The advantage of such a device is that it offers a good video signal, so you don't see data loss or ghosting.

The resolution which is supported by the switch device will vary, from low to high quality and resolutions of 1920x1440, running at 60Hz. The bandwidth which can be used can be at 250MHz or even bigger.

There are some versions available which offer matrixes of 16x16, 8x8, 4x4, 2x16 and so on until 2x2. These impressive units will usually come with both a splitter and a switcher for the video, as well as the option to mount them in racks. It can be quite useful if you want to mount a large number of switches.

The VGA switch is controlled with the help of buttons in most cases, but you can also use remote controls, TCP/IP and RS232. Thanks to the VGA switches which are available these days, you don't have to unplug and plug back cables with video signal when you want to use the display for a different purpose.

The VGA switcher is compliant with RoHS, FCC and CE and it will provide support for protocols which include DDC2AB, DDC2B+, DDC2B, DDC2 and DDC1. One of the nice things about this type of switch is that it's hot pluggable, so you can use it even if the device is running already.
