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. ATHDSync 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 informa-
tion for configuration purposes, so the monitor and system can work together.
• HDMI 1.3c, DVI 1.0 and HDCP 1.1 compliant
• Built-in default EDID
• Able to read and store the EDID of monitors/projectors
• Prevent computers from deactivating inactive HDMI ports
• Able to write EDID into the AT-HDSync or the DVI monitors/projectors
• Maintain HDMI™ video resolution
• 1x AT-HDSync unit
• 1x 5V DC power supply unit
• 1x User’s manual
