XGA-2 Setup

Remarks: The following table shows only the key-resolutions which are included in the most drivers and which are mainly used by the applications. The XGA-2 however is (relatively) free programmable for all resolutions / refresh-rates, which do not exceed the maximum bandwidth of the adapter.

There is no such "top resolution" - it is only limited through

  • number of vertical and horizontal pixels
  • rate of vertical refresh
  • colour depth
A resolution of 1300 x 1024 is possible - but uses a refresh of only maximal 43Hz interlaced, which is not ISO-compliant.

The maximum ISO-compliant resolution is 1024 x 768 at 75Hz non-interlaced. Though: some DMQS-files allow resolutions over 1024 x 768 - but with non-ISO compliant refresh rates and only with 16 colours (4 bit / pixel).

The XGA-2 is capable to handle a color-depth of 16 bit / pixel, which is 65536 colours, commonly called 64K- or Hi-Color mode.
