What is Video Palette Snooping?
The PCI/VGA Palette Snoop is an option in the CMOS setup that can be Enabled or Disabled and enables PCI cards that do not contain their own VGA color palette to examine the video cards palette and mimic it. This feature was required for some MPEG decoder cards, TV cards, and other unique expansion cards that worked with graphics. However, today this feature is rarely used and should be Disabled in your CMOS unless you're computer is utilizing a card that requires it.
How do I disable the Palette Snooping?
If available, the Palette Snooping can be disabled by entering the computer CMOS setup and within the settings, changing it to disabled.
