The Video Electronics Standards Association (VESA) is an international body, founded in the late 1980s by NEC Home Electronics and eight other video display adapter manufacturers. The initial goal was to produce a standard for 800x600 resolution video displays. Since then VESA has issued a number of standards, mostly relating to the function of video peripherals in IBM PC compatible computers.

Among VESA's standards:

• VESA Feature Connector (VFC), obsoleted connector that was often present on older videocards, used as a 8-bit video bus to other devices
• VESA Advanced Feature Connector (VAFC), newer version of the above VFC that widens the 8-bit bus to either a 16-bit or 32-bit bus.
• VESA Local Bus (VLB), once used 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)
• 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
• Flat Display Mounting Interface (FDMI), which defines "VESA mounts"

Thu, 03 Jul 2008 14:11:01 -0700
The Register covered a very interesting story about AVG.  Apparently AVG is spamming the Internet with traffic that looks to be coming from Internet Explorer.  AVG software pre-crawls search results to try to protect users, but uses a user agent that makes the software appear to be Internet Explorer.  This pre-crawling is flooding websites with...
