Q:
Why is the display shifted or changed sizes when I switch display
modes?
Explain and Suggestion:
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. Use the monitor control panel
functions to adjust screen.
In other cases, mode type and refresh rate adjustments may be
necessary. Use the utility program, which provided by video card
manufacturer or production developer. To centering the display with
normal type (mode 3), and to reduce (decrease) the refresh rate with the
monitor's specification.
Q:
What kind monitors can display 800x600 mode or higher resolution
mode?
Explain and Suggestion:
To display 800x600 resolution at 60Hz refresh rate, the monitor must be
capable of synchronizing a 31.5KHz horizontal scan rate (e.g., NEC 2A,
3D). At 72Hz refresh rate, the monitor must be capable of synchronizing a
48.0KHz scan rate (e.g., Sony HG 1304, NEC 4D, 5D, Seiko 1450).
To display 1024x768 interlaced mode; the monitor must be capable of
synchronizing a 35.5KHz horizontal scan rate (e.g., NEC 3D, Seiko 1430
or 1440). To display 1024x768 non-interlaced mode at 60Hz, the monitor
must be capable of synchronizing a 48.7KHz scan rate (e.g., Sony HG
1304, NEC 4D, 5D, Seiko 1450).
To display 1024x768 non-interlaced mode at 70Hz, the monitor must be
capable of synchronizing a 56.4KHz scan rate (e.g., NEC 4D).
