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 connector (below images) and VGA and SVGA cabling.

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.
