SENSATION! (250-1650) Video Modes Faxback Doc. # 1235 Your computer is preconfigured to use the highest resolution video mode available with your applications. If you require video modes for additional software applications or for higher screen resolution, you may need to change the mode as instructed in this chapter. Contact your computer dealer if you do not want to change the video mode yourself. Mode 3 (80-column text) is the default video mode of the video circuitry. In addition to the default, the video circuitry supports the following classes of video modes: * Standard VGA modes, EGA modes, and MCGA modes--Provide video resolutions of up to 640 x 480. * Super VGA modes--Provide even higher resolutions and the ability to display more colors simultaneously. Super VGA can also display text 132 columns wide and 25, 28, 44, or 50 lines deep. * CGA, Hercules, and MDA modes--Required by applications designed to run under Hercules-compatible software and some CGA-compatible games, you must use a Hercules or a CGA mode. When in a CGA, a Hercules, or an MDA mode, the video circuitry emulates the earlier video standard. The video mode tables "Operation" list the supported video modes and resolutions available under each video Standard Video Modes: TYPE(1) VIDEO COL. X RESOLUTION COLORS CHAR.
