The Atlona Etude™ Sync (AT-ETU-SYNC) provides EDID emulation and Hot Plug Detect communication between
HDMI® sink and source devices. It detects and corrects for signal integrity issues associated with cabling or

communication with the source. This device is ideal for AV system troubleshooting as well as ensuring reliable,
consistent performance.
