Atlona Inc. AT-ETU-SYNC Edid Emulator 4K Hdr Hdmi

Product Description

The ATLONA INC. AT-ETU-SYNC is an EDID emulator designed for use with 4K HDR HDMI signal chains. EDID, or Extended Display Identification Data, is the handshake protocol that tells a source device what resolutions, color depths, and audio formats a display supports. The AT-ETU-SYNC stores and transmits that EDID data independently, allowing source devices to maintain stable output even when the downstream display is powered off, swapped, or unavailable. AV integrators and systems technicians install this device to eliminate blank-screen events, resolution drops, and signal negotiation failures in professional and residential installations.

The AT-ETU-SYNC is suited for installations where HDMI sources must remain active regardless of display state. Typical use cases include conference rooms, digital signage systems, multi-display video distribution, and home theater setups where the source device needs a consistent EDID reference. It is categorized as an HDMI extender accessory and ships as a single unit. Installations involving 4K HDR content streams benefit from this device by ensuring the source continues to output at its intended resolution and HDR format without renegotiating on every display power cycle.

Installation Notes

Installation is typically performed by a licensed AV technician or low-voltage systems integrator. Power down or standby all connected source and display equipment before inserting the device into the HDMI signal path. Verify that the HDMI cable lengths and quality meet the requirements for 4K HDR signal integrity before and after the emulator. Follow applicable low-voltage wiring codes and the facility's AV system documentation when integrating into an existing signal chain.
