What is the difference between VGA, SVGA and UXGA
The terms VGA, SVGA, XGA, SXGA, UXGA etc., all relate to the resolution a
Monitor supports.
The video format is the same despite the different designations and as an
example a UXGA monitor can
Display resolutions from VGA all the way up to UXGA. In all cases they use
the same HD15 Interface and
cabling.
The relationship is as follows
Legacy Resolutions no longer supported(included only for reference)
---------------------------------------------------------------------
(Color Graphics Adapter).....................................CGA: 320 x 200
(Enhanced Graphics Adapter).............................EGA: 640 x 350
---------------------------------------------------------------------
(Video Graphics Array)........................................VGA: 640 x
480
(Super Video Graphics Array).............................SVGA: 800 x 600
(High Definition Television 720i/p).......................HDTV: 1280 x 720
(Extended Graphics Array)..................................XGA: 1024 x 768
(Wide Extended Graphics Array).........................WXGA: 1366 x 768
(Super Extended Graphics Array)........................SXGA: 1280 x 1024
(Super Extended Graphics Array+)......................SXGA+: 1400 x 1050
(Wide Super Extended Graphics Array)...............WSXGA: 1600 x 1024
(Wide Super Extended Graphics Array+).............HDTV: 1920 x 1080
(Ultra Extended Graphics Array ).........................UXGA: 1600 x 1200
(Wide Ultra Extended Graphics Array).................WUXGA: 1920 x 1200

(Quad Ultra Extended Graphics Array).................QUXGA: 3200 x 2400
(Wide Quad Ultra Extended Graphics Array)........WQUXGA: 3840 x 2400
(Hex Super Extended Graphics Array)..................HSXGA: 5120 x 4096
(Wide Hex Super Extended Graphics Array).........WHSXGA: 6400 x 4096
(Hex Ultra Extended Graphics Array)....................HUXGA: 6400 x 4800
(Wide Hex Ultra Extended Graphics Array)..........WHUXGA: 7680 x 4800
Regardless of what resolution a Monitor or Video Card is able to support,
they are commonly referred to as
just being VGA, the naming conventions listed above never really caught on
with the general public and thus
even the most High End 3-D Graphics card from Companies like NVIDIA or ATI
will have what they term a VGA
port (in addition to a DVI port in many cases) even though the card may output
resolutions greater than
1920 x 1440.
Some High End Monitors support resolutions up to 2048x1536 @ 79Hz, which
is still part of the same
Multisync format and is backwards compatible to lower resolutions. Most High
End Monitor Manufacturers
don't mention VGA, SVGA etc at all, they typically refer to Monitors as CRT's,
LCD's or Plasma Displays and
list the maximum resolution that they support and at what refresh rate.
