The AT-UHD-SYNC 4K HDMI Emulator/Tester from Atlona is designed to analyze errors, identify issues, and restore failed HDMI signals. It also provides a pre-set or learned EDID to an HDMI source, ensuring the HDMI source provides a signal optimized for the display to achieve the best picture and sound. The AT-UHD-SYNC is used by installing it into the HDMI signal path between the source and switcher or between source and display if no switcher is present. The device provides an HDMI input and output on the rear panel for these connections. To test and analyze the HDMI connection, the AT-UHD-SYNC is equipped with three LEDs which indicate the presence and state of 5V, hot plug detect, and HDCP signals, helping the installer isolate the cause of a connection failure. It resolves issues that cause costly and time-consuming troubleshooting calls, such as loss of signal, intermittent or flashing video, snow, and color space incompatibility where the image is tinted purple or green.

The AT-UHD-SYNC performs signal regeneration to resolve clock-stretching issues with unsupported HDMI 1.2 devices. It provides the necessary 5V to the display to initiate an HPD event and establish EDID handshaking. The device can also provide EDID information to the source to ensure the correct video resolution and audio format are sent to the display. The device features a front panel selector with nine preset emulation modes, as well as a learning mode to capture the display's EDID in the event the display does not match one of the presets. The AT-UHD-SYNC allows you to identify problems which are easily remedied by replacing an accessible HDMI cable. For more complex issues involving inaccessible cables, hot plug detect issues, or missing 5V signals, the AT-UHD-SYNC provides you with a quick and permanent in-line solution allowing the system to operate correctly and reliably. This cost-effective device saves the installer valuable troubleshooting time. The device is also a permanent in-line problem solver for HDBaseT distribution applications between HDMI 1.2 compliant sources and HDMI 1.3 or 1.4 compliant displays.

The AT-UHD-SYNC measures less than 3" in width and depth, and less than 1" tall. Its slender design ensures easy integration into confined spaces, and a pair of wall mount brackets is included for ease of installation. It is USB-powered via the supplied 5 VDC/1A power supply or from local USB devices using the included Mini USB to USB A cable.
