You will most likely never need to buy a new VGA cable. Every new computer setup includes one of these, and it’s really only when yours breaks down or you have a very unique type of setup requirement that a new cable is needed. However, if the time comes, it’s worth knowing a little about this type of cable and what to remember when shopping for a new one.
First, understand what it is. A VGA cable is a video graphics matrix cable. It has three rows of five pins to deliver the video signal and is one of the most common types of cables on the market. The primary use is to connect a computer tower to a computer monitor, and the image you are currently viewing is most likely being transmitted via one of these cables.
With that in mind, you’ve probably assumed that you can order the first VGA cable you come across and get exactly what you need. It’s usually a safe bet, but keeping a few additional things in mind will help you get the best results. One point to remember is that you will need to match your length needs to the correct cable. Buying a cable that is too long will result in a loss of image quality, and buying one that is too short brings obvious limitations. There are a few standard sizes out there, so make sure you get the one that works best for you.
Make sure you don’t need an adapter-style VGA cable. For example, if you’re connecting your computer to an HDTV for some reason, you may need a VGA to HDMI adapter. Many modern televisions have a VGA connector, but these cables are also a viable option. Think about what you are connecting to get the right type of cable for your needs.
Lastly, keep in mind that quality does matter. A higher quality VGA cable will typically include better insulation and good coax on the inside to help reduce signal degradation, prevent ghosting, and give you the best data transfer available. Paying a couple of bucks more for a better quality cable is usually a smart move when you want the best.
These are the only real concerns to pay attention to when you start shopping for a replacement cable. Remember them and you will have no problem finding the right one.
