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 PCI video cards designed for Plug-n-Play, that means video
card IRQ’s setup which controls by main board’s (mother board)
circuitry and BIOS. Physically pulling out other devices from
system, and re-start 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, and 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 support 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 back to default after restart the system.
