In a desktop computer setup, the VGA cable connects to the system unit to display on the monitor, The VGA cable transmits analog signals and can support resolutions up to 640 x 480. While the super video graphic array (SVGA) can carry analog signals and support resolutions up to 800 x 600. SVGA is the enhanced VGA, and it is also called Ultra VGA. Almost all SVGA cables today will support far higher resolutions other than the usual 800 x 600 standard resolutions.
These cables have plugs with their pins arranged in three rows: The first row has 5 pins, and the last rows has 5 pins too, but the middle row has 4 pins, it does look like a pin is missing, but on a contrary no pin is, in fact, missing that’s the 14-pin standard configuration. These cables will plug into any high density, VGA ports or sockets, or on any computer monitors and other compatible devices and display adapters. It’s hard to differentiate between an unlabeled VGA and an SVA cable by mere looking at it, if you have an SVGA cable connected to any compatible device or any graphics card, a default resolution of 800 x 600 should become available.
Cables that are unlabeled in most cases are SVGA cables other than the thinner cables. This is because these SVGA cables normally have much shielding than its other VGA counterpart. If the cable is very thick, then the quality should be great.
SVGA cables will require more video memory and graphic than VGA cables, SVGA cables supports up to 16 million colors. But with VGA cables you will only get a maximum 640 x 480 resolution, in only 16 supported colors.
For better and high-resolution signals to be carried for long distance one will be required to use a better cable than that of the lower resolution signal cables which transmit over short distances. You might face problem of poor signals such as no images or blurred images as a result of using poor quality cables.
When shopping for a new cable, not just VGA cables now, always check first for the configurations of its ports to be used. Female configurations have the hole parts, while the male has the pins, check if the number of rows and the number of pins corresponds.
