Although HDMI is a standard today, a lot of older computers actually use VGA technology. This was an older type of video connection that was created before DVI and HDMI, and is not as common today as it once was. You really can’t just go out and replace your VGA cable with the cheapest one that you can find. There are different resolutions to consider and other elements in the cable that you have to think about.
A VGA cable is actually quite affordable, but you still have to make sure that it has the right components. For example, you might want extra EMI shielding, which is protection from other devices or cables that might affect the VGA resolution or display. If you want the best images possible with this older technology, you need the highest quality VGA cable that you can find. You might pay 2-3 times more, but the resolution quality and other features will usually be worth the investment.
Basic VGA cable resolution is at 640×480. This is usually sufficient for older monitors. People who have replaced their display with HD monitors or even just a newer display with higher resolution are going to need to
get an SVGA or XGA cable, which can support much higher resolution than the basic cable. These cables are all interchangeable and you can use a higher resolution cable with a lower resolution display, but it’s silly to spend the money if it isn’t being used.
