Set EDID Data

Built-in Extended Display Identification Data (EDID) read & write function, with Electrically Erasable Programmable Read-Only Memory (EEPROM), to save display EDID data while supporting any HDTV with maximum resolutions.

The unit also supports non-Video Electronics Standards Association (VESA) resolution, including projectors with unique resolutions. This function is easy to set up by the user If you use DVI monitors, should be set the EDID first.

**** EDID [Extended Display Identification Data] EDID is defined by a st
