A VGA extension cable is the one responsible for the transmission of video signals from personal computers or laptops to monitors or projectors. You may have also heard them being called the VGA extension, monitor cable, VGA video cable, and computer cable. With these cables, it is possible for a computer to be separated from its monitor at a greater distance. In fact, if you use a VGA extension cable, you will still be able to see the screen which is 100 feet away from the computer itself.
If you need to place the monitors farther than 100 feet, it is recommended that you use Cat5 and UTP VGA Video splitter Extender. The reason for this is that VGA cables are likely to be expensive.
Using a VGA extension cable will also ensure that you get to see an excellent quality of picture with the resolution of 1600 x 1200. You can also use these type of video cables with PC, MAC or SUN systems that come with VGA video connectors.
These cables are made with coaxial and twisted pair signal lines aside from ferrite cores on one of the ends, making it very capable of providing optimum video quality and performance. The VGA connectors are coated with copper braiding and aluminized Mylar foil. You will also see that there are gold plated pins on the connectors. These pins are used to suppress the noise, while the triple coating feature guarantees that there will be no loss of data.
In addition to being made using multicultural technology, these VGA extension cables are UL tested and also certified. You can find these cables in lengths between 3 feet and 100 feet.
A VGA extension cable is also available in both male to male and female to female connectors. You will see that they have 15 pins. There are 3 rows and each row has 5 pins. You can find these connectors on cameras, video cards, computer screens, high definition TVs and projectors. The main purpose of these cables is to carry the analog aspect of the video signals.
The fast development of technology has led to the popularity of DVI cables over these VGA cables. There are still, however, a number of old version graphics cards that still has the 15 pins to get the video graphics controller connected to the monitor through a VGA cable. These cables are also much cheaper than the ones used for digital signal transmission.
