This HDMI 2.0 splitter distributes an HDMI signal up to Ultra HD resolution to 2 HDMI devices, such as TVs, monitors, projectors, or AV receivers. The splitter is backward compatible with lower resolutions at both the input and output. Through an integrated downscaler, 4K content can be displayed on a Full HD display. This allows for mixed operation of a 4K TV and a Full HD TV. An HDR signal remains HDR and may often not be processed correctly by the Full HD device. Therefore, when outputting both 4K and Full HD simultaneously, SDR should be set at the source. Additionally, the audio mode can be selected via a switch. This allows you to set the HDMI source to deliver the best possible audio format (Maximum) or an audio format that both connected HDMI devices support (Minimum). Please note that when connecting to an older AV receiver, it may not be able to process the HDR signals contained in the signal and may require an SDR signal.
