5.2 Commonly Asked Questions
5.2.1 Monitors
Why
does
the
display
shift
or
change
sizes
when
I
switch
modes?
Some monitors lack auto-sizing features or just do not synchronize
properly
to
the
video
board
output.
In
some
cases,
horizontal
and
vertical display adjustments may be necessary.
What kind of monitor do I need to display 800x600 or 1024x768
resolution?
To display 800x600 resolution at 56Hz refresh, your monitor must be
capable of a 35.2KHz horizontal scan rate (e.g., NEC 2A, 3D). At
72Hz refresh, your monitor must be capable of a 48.0KHz scan rate
(e.g., Sony HG 1304, NEC 4D, 5D, Seiko 1450.)
To display 1024x768 interlaced, your monitor must be capable of a
35.5KHz horizontal scan rate (e.g., NEC 3D, Seiko 1430 or 1440). To
display 1024x768 non-interlaced, your monitor must be capable of a
48.7KHz scan rate (e.g., Sony HG 1304, NEC 4D, 5D, Seiko 1450).
