Check the listing for details. HDMI Video Scaler AMX SCL-1 4K60 (Open Box). Condition: Open box. Listed at 500.00 USD. The AMX SCL-1 4K60 Scaler is a small-format scaler that adjusts the output to match the optimal resolution of the display. The scaler includes a single input and a single output, with a size small enough to be mounted behind a display. It was designed to be used in combination with products such as the local HDMI outputs on the AMX Precis 8x8 that do not have built-in scaling. This offers a more flexible, lower cost solution for installations where scaling is needed only on certain outputs. The scaler is compatible with 4K60 4:4:4 resolutions and HDCP 2.2, offering support for the latest source devices and displays. Because the scaler includes automatic scaling, the device can be configured to automatically scale to the optimal resolution of the display based on its EDID. It can be set to always scale to a particular resolution.
