Today, most video drivers are developed for 32-bit processing and may require a
channel to Code/Decode. Conflict between device drivers and TSR (terminate-
and-stay-resident) programs will inverted the display, and are particularly
effectual at crashing computer. The most
effective way to check for conflicts is to
replace with the original video driver, or delete and re-install the current video
driver to the system.
Accomplishing IRQs (Interrupt Request Query) settings or troubleshooting the
conflicts on hardware source may necessary. Most AGP video cards designed for
Plug-n-Play, that means video card IRQ's setup which controls by main board’s
(motherboard) circuitry and BIOS. Physically pulling out other devices from
system, and re-starts the computer. Confirm and modify your IRQ addresses with
qualified computer technician.
Q:
Multiple images or unreadable screen after loading video driver.
Explain and Suggestion:
There are a variety of reasons why the display might be distorted. One common
reason is a monitor mis-match. Some older multi-frequency monitors are unable
to switch video modes without being turned off, then turned on again.
If the problem occurring in windows, make sure that you have loaded that proper
video driver, and that the driver is compatible with the monitor being used. Try re-
configuring your application software to use a compatible video mode. If problem
persist in windows, load the standard generic VGA driver. The generic VGA
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.
