Model Number: AT-HDSync

Read, copy and replicate almost any EDID with the AT-HDSync. With built in EDID memory the HDSync is perfect for large installations where EDID issues usually occur. Simply learn the display’s EDID, place the HDSync in the line next to the source and watch HDCP and EDID problems disappear. The Atlona HDMI Recorder and Hot Plug Emulator is an easy and affordable solution for some of the most common installation problems out there.


Take the EDID not the display

  • The AT-HDSync’s nonvolatile memory makes any EDID fully mobile. Save any display’s EDID and take it to the job site or a different end of an installation, avoiding heavy lifting, recabling, and extra time on troubleshooting.

Ensure the best connection

  • With a hot plug emulator and the ability to boot the source directly from the HDSync, ensure stable signals and proper pass through of EDID and HDCP.

EDID at your fingertips

  • Analyze, troubleshoot, or save an EDID with the (included) HDSync’s software. With just a click of a button find the root of most compatibility problems, analyze an EDID before installation to make sure it works with other devices, or simply read an EDID to make sure it has the resolution and audio needed.
