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.
