Someone tell me what does VGA mean? —– Imacer99 Comments: One Response to “Video size with VGA” Gary Rosenzweig 10 years ago VGA is just a graphics standard. 640×480 is the part you need to worry about. Sometimes you will hear someone say “VGA” and they usually mean 640×480. Sometimes 720×480. Back in the days where 640×480 monitors were common, those monitors were often referred to as VGA. The connectors that connected the computer to the monitor were also called VGA cables. But those cables have survived and are often still used today to connect to monitors or projectors at much higher resolutions than 640×480.
