The Atlona HDMI Recorder, Writer & Hot Plug Simulator with RS232 Control is a device that can emulate the EDID (Extended Display Identification Data) information. It stores the EDID information and recalls a default EDID setting in non-volatile memory that supports HDCP handshaking. AT-HDSync allows your HDMI source boot directly from AT-HDSync, so users will not have to worry about losing EDID in a complex set-up which is commonly an issue. 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 (for display manufactures only).
The AT-HDSync can also generate a missing Hot Plug, which sometimes is missing and therefore the HDCP and EDID handshake can't happen. The HDSync will stay inline to maintain the Hot Plug at all the time.
