When selecting a VGA cable, make sure to choose a cable that is no longer than strictly necessary. This way you avoid unnecessary loss of quality. Before ordering a cable, note the resolution your equipment uses. Higher resolution requires a higher quality cable. Choose a cable that is suitable for the same or higher resolution. With a VGA converter it is possible to connect your VGA equipment to an HDMI input or output.

What exactly is VGA?
For years, VGA (Video Graphics Array) has been an important connection standard for computers to connect to a display. At the time, there were only analog CRT monitors. So it was a logical step to get the entire conversion from a digital to an analog image signal that could easily be converted into a monitor to a visible image by having the PC do it.
Due to the developments in the computer industry, a new version has been released regularly to be able to display the higher image resolutions. The various options such as color depth, color pallet and resolution were originally indicated with a letter combination such as SVGA, XGA, SXGA, UXGA. These letter combinations have become obsolete because they were difficult to remember and in practice it is easier to indicate the properties of equipment with the maximum image resolution. An analog image signal transmission such as with VGA has a number of drawbacks. This is also the main reason why this analog connection is increasingly omitted with new equipment, in favor of the digital HDMI or DisplayPort connections.
VGA Cable Properties
A VGA cable contains no active components and has a standard connector. This is a DB 15 connector. A computer and monitor almost always have a female DB 15 connector. A standard monitor cable therefore has two DB 15 male connectors.
The VGA extension cable has a DB 15 plug on one side and a DB 15 socket on the other. There is no limit for the maximum length of a VGA cable, but because it is an analog image signal, the quality per meter of cable will decrease slightly. You will never notice this with a short cable, but it can be clearly seen if you use a longer cable.
Each VGA cable is wired the same way, making it suitable for different resolutions. Nevertheless, you will find a classification of cables according to resolution. A signal for a higher image resolution takes up more bandwidth. At a higher resolution, a cable must therefore be suitable for signals with a higher frequency. If you use a cable that is only suitable for a low resolution, this will result in a less sharp image for a high image resolution.
Choose the right cable
When choosing a VGA cable, it is important to ensure that the cable is never longer than strictly necessary. Each additional meter will cause a slight extra attenuation of the signal, something that will give a slightly lesser picture quality.
Make sure to select the desired cable length. In addition, it is important to choose a cable that is suitable for the image resolution of your device. A high image resolution requires more bandwidth and therefore a higher quality cable. You can use a cable with a high image resolution without problems or loss of quality for a signal with a lower resolution.
Select the resolution used by your equipment. If you want to transmit the image signal over a long distance, you can find solutions that have been specially developed for this purpose. With a VGA extender you can bridge a distance of up to 300 meters without any problems. An extender consists of a local and a remote unit that are linked via a UTP cable.
Adapters and inverters
Situations regularly arise where it is not possible to connect a cable directly. If you want to connect VGA cables to each other, you can choose VGA adapter. With a VGA splitter it is possible to split the image signal into two different signals. A splitter is ideal if you want to connect multiple monitors to the same output.
You will find various passive and active splitters with two or more outputs. The active splitters are ideal for an information system where multiple monitors are hung in different places. If you want to connect a monitor that has an HDMI input, order a VGA to HDMI converter.
Note: these converters contain a chip and only work in one direction. If you want to convert the signal the other way around, choose the inverted converter. In addition to these converters, you can also find converters that can convert the signal to lesser known and older standards like DVI, DisplayPort, mini DisplayPort, S-video, BNC, SDI and SCART.
