Atlona Etude Sync 4K HDR HDMI EDID Emulator - AT-ETU-SYNC
Product Overview
The Atlona AT-ETU-SYNC (Etude Sync) is an EDID emulator and HDMI signal management utility designed for professional AV integrators troubleshooting 4K HDR HDMI systems. It provides EDID emulation, Hot Plug Detect communication, and 5-volt signal restoration between HDMI source and sink devices, resolving the most common handshaking failures in commercial AV installations. Supporting HDCP 2.2, 4K/UHD video at 60 Hz with 4:4:4 chroma sampling, and 18 Gbps bandwidth, the AT-ETU-SYNC is a compact, field-portable diagnostic tool for HDMI EDID troubleshooting and legacy device integration in any AV system.
Product Description
The Atlona AT-ETU-SYNC Etude Sync is part of Atlona's 4K HDR integration product family, purpose-built to identify and resolve signal integrity issues that arise between HDMI sources and displays in commercial and residential AV systems. EDID mismatches and Hot Plug Detect failures are among the leading causes of unreliable HDMI performance, and the AT-ETU-SYNC addresses both by providing EDID to the source device from either the connected display or its own internal memory. The device can capture and store EDID from a downstream display, ensuring that the source always outputs the correct resolution and audio format regardless of what is connected downstream. The AT-ETU-SYNC also restores the +5V and HPD signals lost due to faulty, long, or incompatible cabling — enabling the handshaking sequence required for stable video delivery. It supports the full range of 4K/UHD resolutions up to 4096x2160 at 60 Hz, HDR10, and Dolby Vision at 60 Hz, as well as a comprehensive VESA resolution set for PC sources. Multi-channel audio pass-through includes PCM, Dolby Atmos, Dolby TrueHD, DTS:X, and DTS-HD Master Audio. A particular strength of the AT-ETU-SYNC is enabling legacy HDMI source devices — such as cable television set-top boxes — to function in systems that use HDBaseT extenders, which require HDMI clock stretching support that older sources often lack. Front panel LED indicators provide immediate status feedback for the +5V source supply, Hot Plug Detect, and HDCP compliance at both the source and destination, allowing AV technicians to diagnose connection problems rapidly without additional test equipment. The device is USB-powered and ships with a universal power supply, making it equally convenient for permanent rack installation and portable field troubleshooting. Firmware is field-updatable via the USB port.
