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.
Frequently Asked Questions (FAQ)
Q1 Why do we need 3D graphics capability in our PC?
Answer
3D technology is becoming increasingly important (and common) not only in
games, but also in other applications such as VRML, which allows 3D scene
descriptions in Web applications. 3D technology is used for image editing,
modeling, and an increasing number of in home and business applications. In
games, as well as other applications, 3D acceleration not only allows better visual
qualities and more realistic scenery attributes than software alone, but it also
allows a higher frame rate, which translates into a more interactive experience for
the end user.
Q2 What does “Rendering Engine” mean?
Answer
“Rendering Engine” generically applies to the part of the graphics engine that
draws 3D primitives, usually triangles. In most implementations, the rendering
engine is responsible for interpolation of edges and "filling in" the triangle.
Q3 What does the set-up engine do in a graphics controller?
Answer
A set-up engine allows drivers to pass triangles in the form of raw vertex
information; whereas, most common designs force triangles to be pre-processed
for the rendering engine in terms of delta values for edges, color, and texture.
