VESA Guide, Meaning , Facts, Information and Description

The Video Electronics Standards Association (VESA) is an international body that has issued a number of standards, mostly relating to the functioning of video peripherals in IBM PC compatible computers.

Among VESA's standards:

• VESA Local Bus (VLB), used at one time as a fast video bus (akin to the modern AGP).
• VESA BIOS Extensions (VBE), used for enabling standard support for advanced video modes (at high resolutions and color depths)
• VESA Display Data Channel (DDC), allowing monitors to identify themselves to the video boards they're attached to. The format of the actual identification data is however called extended display identification data (EDID).
• VESA Display Power Management Signaling, which allows monitors to be queried on the types of power saving modes they support
• A number of standards relating to flat-panel screens, video connectors, video cable timings etc.
• Digital Packet Video Link
