What is Video Palette Snooping?
The PCI/VGA Palette Snoop is an option in the CMOS setup that can be toggled to enable PCI cards to examine a video card's palette and mimic it. It is useful for cards that do not contain their own VGA color palette. This feature was required for early 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 your 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.
