Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

  Synopsis:  Specifies the VESA video screen mode for all graphics
             operations. VESA is an acronym for Video Electronics
             Standards Association.

     The <mode> argument to the _setvideomode function can be one of the
     following manifest constants (defined in GRAPH.H). These constants
     support screen modes specified by VESA. Other nonstandard Super VGA
     modes may also be supported. Note that some, or all, of these
     manifest constants may be supported by graphics cards that support
     the VESA Super Video standard VS891001. Other modes may also be
     supported; a TSR driver may be required. For more details on these
     constants, see Chapter 9 of the Programming Techniques manual.

     Warning:  DO NOT attempt to set _SRES16COLOR, _SRES256COLOR,
               _XRES16COLOR, _XRES256COLOR, _ZRES16COLOR, or
               _ZRES256COLOR without ensuring that your monitor can
               safely handle that resolution. Otherwise, you may risk
               damaging your display monitor! Consult your owner's
               manual for details. The _MAXRESMODE and _MAXCOLORMODE
               constants never select these constants.
