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.
HTX series matrix switcher provides Auto EDID management system to meet today's sophisticated digital
connectivity integration environment.
Auto EDID management system
EDID library
15 most widely used EDID data is pre-programmed internal EEPROM chipset which user can take and save
onto the any of the matrix switcher's Input EEPROM.

4K@60Hz, HD audio
Factory default EDID is set to 1920 x 1080p@60Hz
By optimizing factory default EDID and EDID library feature, in most cases, HTX series matrix switcher will
work out of the box without any additional configuration.
Emulation
The user can easily save an EDID data from any display devices directly onto the
matrix switcher’s input port.
By saving display device's EDID information on the matrix switcher input port, input port will act as a display to
the video source.
