INTRODUCTION
Atlona Technologies AT-HDSync HDMI™EDID Recorder-Writer with Serial Control is a device
that can emulate the EDID (Extended Display Identification Data) information. It stores and
recalls a default EDID setting in non-volatile memory and supports HDCP handshaking. AT-
HDSync allows your HDMI™source boot directly from AT-HDSync, and users can detach
HDMI™monitor at any time while installing AT-HDSync between HDMI™source and monitor. It
can also read and store the EDID of your HDMI™display and even let you modify the EDID
and upload the modified EDID to displays.
Note: Extended Display Identification Data (EDID) is a standard data format that contains basic
information about a monitor and its capabilities, including vendor information, maximum image size,
color characteristics, factory pre-set timings, frequency range limits, and character strings for the
monitor name and serial number.
The information is stored in the display and is used to communicate with the system through a
Display Data Channel (DDC), which sites between the monitor and the PC graphics adapter. The
system uses this information for configuration purposes, so the monitor and system can work
together.
