Using the Display
Using a DOS Application with Your 755CX SVGA Model
When you use a DOS application that supports only VGA mode
(640-by-480 resolution) with your 755CX SVGA model, the screen
image might appear smaller than the display size shown in the
following table. This is to maintain compatibility with DOS
applications.
Note:
* When you select Both, do not
attach the external display that
supports only VGA mode
(640-by-480 resolution). Otherwise,
the screen of the external display is
disordered and the output is not
displayed.
