Je to dobry na tohle .....

Display Data Channel
------------------------------------------------------------------------
A VESA standard for bidirectional communication between PC monitors and
video adapters. The monitor continuously sends its 128-bit Extended Display
Identification (EDID) message to the video adapter. This specifies the
following: 

Screen resolutions supported (and refresh rates for each) 

Screen dot-pitch and the monitor's bandwidth 

Power-conservation capabilities (that is, DPMS support) 

Product information, such as the model number (to help match the video
driver software to the adapter and monitor) and MPR support 

This enables the video adapter to automatically select the highest
resolution supported by a monitor and prevent users from selecting
unsupported modes. 

The monitor can also be controlled (for example, setting the refresh rate,
resolution, color temperatures, screen position, brightness, and contrast),
through the use of easier-to-use standard PC utilities, rather than
monitor-specific utilities or front-panel push-buttons. 

Uses ACCESS.bus. Some monitors will have an ACCESS.bus port on them (for
connection to additional peripherals), simplifying the cabling.
