EDID
Media Axis Extenders provide an Auto EDID management system; an easy and fail-safe way to handle
EDID, via the EDID library system and EDID emulation.

ata (
EDID
) is an information set that digital display provides to describe
its capabilities to a video source. Video sources 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 the manufacturer
’s name and serial number, sets of capable resolution
including native resolution, supported timing, pixel mapping data (for digital displays only), etc.
In a digital connectivity environment; in order to support the maximum resolution of the connected
monitor, the EDID handshake is critical because improper EDID handshake between sources and displays
will result in no image on being displayed.
EDID handshake may sound simple; however, with multiple peripheral devices within the chain, the
display's EDID information can easily get lost or blocked while it is traveling to the source device.
Media Axis provides an Auto EDID management system to meet today's sophisticated digital
connectivity integration environment.
EDID Library List
Some of the most widely used EDID data are pre-programmed into the internal EEPROM chipset.
By optimizing factory default EDID and EDID library features, in most cases, Media Axis Extenders will
work out of the box without any additional configuration.
Emulation
The user can easily save the EDID data from any display directly onto the Media Axis Extender
Transmitter. By saving the display
’s
EDID information on the transmitter, it will act as a display to the
Video source.
* Connect a display to the Media Axis Extender Transmitter's HDMI port and then press the EDID S/W
button. It will copy and save the
display’s EDID information to
the Media Axis Extender Transmitter.
NOTE:
There may be display devices that will not allow another device to emulate its EDID data.
NOTE:
Certain EDID data may not be compatible with some devices, in this case, it is
recommended to use the scaling receiver.
