2 unusual facts about Mode X


Mode X

Mode X is an alternative video graphics display mode of the IBM VGA graphics hardware that was popularized by Michael Abrash, first published in July 1991 in Dr. Dobb's Journal, republished in chapters 47-49 of Abrash's Graphics Programming Black Book (now freely available online).

The primary advantage of Mode X is that it has square pixels: a resolution of 320x240 instead of the VGA standard Mode 13h which is 320x200.
