How to Pick the Right VGA Cable
A computer monitor needs a VGA cable or a Video Graphics Array cable. VGA cable is mainly responsible for video signal transmission from a one device to another.
When you buy a computer it comes with its own VGA cable yet there will be instances that you will need to purchase a new cable. If your cable is severed or too old to function or if you need a longer cable then you will purchase another set.
In any case, it pays to recognize the features of VGA cables, so that you can make a smart decision when buying.
[b]Shielding[/b]
Perhaps you’ve already seen cables with double or triple shielding. Shielding is essentially a VGA cable feature that shields the cable from crosstalk or the unwanted transfer of signals.
Cables experience Electric Magnetic Interference or EMI from neighboring devices and cables and that affect signal transfer. This crosstalk takes place during signal transmission and to solve this problem the cables require shielding.
A VGA cable‘s core is wrapped up with foil and this is the shielding. Usually, cables have shielding but when you like to totally avoid any then you must select a VGA cable that has a double or triple shielding. However, they are expensive compared to with cables who have single shielding only. There are also cables which can withstand oxidizing and these cables which are gold plated. Cables that are comprised of copper also provide more powerful signal transmission.
[b]Ferrite Cores or Suppressors[/b]
One way of minimizing EMI is to search for VGA cables with ferrite cores or suppressors. Ferrite cores appear like barrels placed outside of the cable and next to the plug.These materials soak up unwanted high frequencies, thus video data signals pass through without hindrance.
Ferrite cores are necessary, specifically if you are using long VGA cables. Cables that are above five meters long have a greater chance of getting interferences. There will be situations when you may have to run a cable over long distances, and that is where you will need a VGA cable with ferrite cores or suppressors.
[b]VGA Extender[/b]
Oftentimes you just have to place your monitors far from the computer. Once you must place your monitor away from the computer at, say, above 100 feet, you should have a VGA Extender to make sure that the signal remains rich. Video quality suffers at long distances, therefore you require a VGA extender so that you will still get high quality videos.
A word of warning, though: cables with extenders are a lot more costly compared to regular VGA cables. Regardless of the high price point, it is certain that you can obtain high video quality even at long distances.
To make sure that you're getting value for your money, seek for cables from trustworthy shops on the internet or otherwise. A quick search on the Internet gives you a long list of online shops that carry VGA cables.
