5 .0 OPERATING THE UNIT
In most cases, the default configuration is sufficient for proper operation; however,
this extender set includes 4x EDID modes to optimize system performance.
EDID (Extended Display Identification Data) is a small data file stored in virtually
every TV, monitor and display device made over the last twenty years. This
file contains information about the display’s capabilities, such as its supported
resolutions, refresh rates, color space, type of display, manufacturer, serial
number, etc. After connecting a display to a source device, the source reads
and saves the EDID in order to determine the most suitable display parameters
(e.g. resolution and refresh rate). In this way, EDID plays an essential role in the
modern “Plug & Play” user experience.
The DVI-7365 has four (4) EDID operation modes.

Note 5-1:
Pass-through EDID mode is the only mode that supports live DDC
