driver should function properly with virtually every video board and VGA (or
SVGA) monitor available.
If that is an unsatisfactory solution, you may have to upgrade to a monitor that
supports the desired video mode.
Some new monitors are also synchronizing this problem because built-in DDC
(Data-Digital-Channel) feature. Sometime that DDC automatically setup the
display frequency without loading video driver. Try to turn it off, or change
settings of monitor type in your system.
Q:
Selection of color, resolution and refresh rate combination that always backs
to default after restart the system.
Explain and Suggestion:
Accordingly, there must be a bug (defected source-code) in video driver, or in the
system. Debug the source-code or fix the error in video driver that should be
done by the driver developer. Likewise, upgrade the video driver from the
manufacturer or from the original software developer is necessary.
