How to make a VGA cable

VGA cable is popular with gamers and computer users for transmitting video signals. Usually used to connect computers to screen monitors, Video Graphics Matrix (VGA) cable can be used in high-definition televisions, computer games, and other electronic devices. VGA cables are part of the D-sub group which is a common type of electrical connector that has been around since computers were produced. At the time they lived up to their ‘subminiature’ name as they were small at the time, but today they are one of the largest common connectors and the name does not have much relevance.

VGA cables

The VGA cable is characterized by 3 rows of 15 pins on the plug. There are several cables that connect to the pins, but this is not relevant to your task. Two screws on each side of the pins serve to secure it in place in the socket and have knurled edges. The screws should be manipulated by hand rather than with a screwdriver. You can make an emergency cable with a trip to the computer store and the following simple instructions.

Step 1: Buy the shorter CAT5 cable

Note that you can remove part of the cable and connect it to the TV or computer product. Strip off about an inch of the CAT5 outer insulation and eight different colored wires will be exposed. These cables should not be rearranged or tampered with, but simply exposed. Strip about 3 mm of the internal insulation of the cable with a wire strippers.

Step 2: solder the cables to the VGA connectors

Keep in mind that the best connectors are male. The part of the VGA cable that contains pin contacts is called a male connector, while the part that contains plug contacts is called a female connector. The plug protector fits snugly inside the plug protector that is attached to the cable shields. Work carefully and wait a moment before covering them with VGA connector housings to make it look better and more secure. Some cables and connectors may not need additional coverage, but it is a good safety precaution.


Step 3: repeat steps 1 and 2

At the other end of the cable, solder the cables. This will ensure that both ends of the connection can send and receive signals and function properly.

Step 4: connect the cables

Make sure the cable is secure and the cables are contained. Check the graphics card settings; otherwise the cable will not transmit images at all and you could be looking at a blank screen when there is no video graphics.

Making your own VGA cable might come in handy if you can’t afford a cable while on vacation or in a certain area. Although it won’t be much cheaper, it will be a fun project that won’t take too long. When you complete this project, you will have a better understanding of how early computer engineers managed to make cables that were “sub-miniature”.
