VGA cables, what in the world are they? When you’re researching computers and/or monitors, you see or hear the term VGA cable thrown around and you have no idea what it is or what it can do for you. You wind up completely confused and frustrated with your research. Perhaps this article can simplify or clarify VGA cables for you.
A VGA cable is the abbreviation for Video Graphics Array. VGA is the graphics display system for PCs developed by IBM in 1987. Almost all PC manufacturers have conformed to this technology today, making the VGA cable the lowest common denominator that all PC graphics hardware supports before a specific driver is loaded into the computer. The VGA cable is the display standard for the PC. All PC display adapters made today support VGA. All Windows machines boot up in “VGA mode” before switching over to a higher resolution.
VGA cables also refer to the 15 pin plugs and sockets that connect the computer to the monitor. VGA cables use a traditional analog connection to a monitor as opposed to DVI, which is a digital connection. So you’re wondering about the resolution of the VGA cable? VGA resolution is 640X480 pixels with 16 or 256 colors. This base resolution is used when booting the PC. This same VGA resolution is used in Safe Mode when you are troubleshooting because the display driver, when set at a higher resolution could be causing the problem that you are troubleshooting. Still confused by all the technical terms about VGA cables? To summarize, a VGA cable is the cable connecting your PC to your monitor and transfers the images from your PC to your monitor.
