SVGA & XGA

Various manufacturers who have tried to tout them as a standard resolution setting have created other subsets of the VGA standard.

For example, the term Super VGA (SVGA) is often used as a catchall term by third party standards that support displays greater than 640x480x16 colors.

Other such terms are abounding such as the Extended Graphics Array (XGA) and 8514/A, both developed by IBM.

The chart should shed some light. It is important to note that the only thing that dictates the resolution and color depth supported by a video card is the amount of memory in the frame buffer.
