What's EDID?
Extended Display Identification Data (EDID) is an information set that digital display
provides to describe its capabilities to a Video source. Video source will know what kinds of
displays are connected and it will determine which resolution to Output according to the
EDID information received from the display.
The EDID normally includes manufacturer name and serial number, sets of capable
resolution including native resolution, supported timing, pixel mapping data (for digital
displays only) and etc.
In a digital connectivity environment; in order to support the maximum resolution of
connected monitor, EDID handshake is a critical because improper EDID handshake
between sources to the display will result in no image on the display.
EDID handshake may sound simple; however, with multiple peripheral devices within the
chain, display's EDID information easily get lost or blocked while it is traveling to the source
device.
