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 multifrequency
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.
