It has a refresh rate of 60 Hz and a resolution of 640×480 pixels. It displays up to 256 colours at once from the 262,144 colour range. It includes a 6-Bit Digital Analogue converter to translate analogue RCB (red, green, and blue) signals.

The first graphics card to provide up to 16 colours at a screen resolution of 640 x 480 pixels was the original VGA graphics card. Lowercase letters might be displayed thanks to VGA’s ability to display up to 256 colours at a reduced resolution of 320 x 200 pixels. It was incorporated into the first OS loading mechanism as a result. As an illustration, Microsoft’s Windows OS has loaded its recognisable starting screen in VGA colour.
