VGA Cables
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.
RGBHV Signal
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 BNC
or 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.
RGB Signal
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.
