CertiGuide to A+ (Core Hardware)

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.

**Table 16: Display Modes and Resolutions**
Display Mode	Resolution	Color Depth
VGA	640x480	16 colors
VGA	320x200	256 colors
SVGA	800x600	True color
	1024x768	65,536 colors
	1280x1024	256 colors
XGA	640x480	65,536 colors
XGA	1024x480	256 colors
8514/A	1024x768	256 colors (interlaced)
