VGA cables can go by many different names. They are commonly referred to as SVGA cables, XGA cables, RGB cables, HD15 pin cables, or analog computer monitor cables. VGA cables have multiple uses and are typically used to carry a RGBHV analog signal from a computer to a monitor. Below we will briefly explain some of the various signal and monitor resolution terminology that you might find when shopping for VGA cables.
A RGBHV signal splits the video signal into five cables (Red, Green, Blue, as well as Horizontal and Vertical sync). Common cable configurations are 5 x BNC to 5 x BNC, HD15 to 5 x BNCor HD15 to 5 x RCA.
RGBS (or RGB H/V) Signal
A RGBS or RGB H/V signal splits the video signal into four cables (Red, Green, Blue, as well as one cable for Horizontal and Vertical sync). Common cable configurations are 4 x BNC to 4 x BNC, HD15 to 4 x BNC or HD15 to 4 x RCA.
A RGB signal split the video signal into three cables, Red, Green and Blue. These cables typically carry the sync info over the green wire, sometimes calling it RGB sync on green. Common cable configurations are 3 x RCA to 3 x RCA, HD15 to 3 x BNC or HD15 to 3 x RCA.
VGA (Video Graphics Array)
Basic VGA supports resolutions of 640 x 480 pixels and 16 colours. This was the standard analog interface used by IBM.
XGA (Extended Graphics Array)
XGA supports resolutions up to 1024 x 768 pixels and 256 colours.
SVGA or SXVGA (Super VGA)
SVGA supports resolutions up to 1600 x 1200 pixels and can displays 16.7 million colours. SVGA is also sometimes referred to as SXVGA (Super Extended Video Graphics Array).
UXGA (Ultra Extended Graphics Array)
UXGA supports resolutions higher than 1600 x 1200 pixels and displays more than 16.7 million colours.
