Introduction
Overview
The 4KSP12-S is a 1 x 2 HDMI splitter with scaler, reliably distributes one HDMI
input signal to two outputs at resolutions up to 4K@60Hz 4:4:4 chroma
subsampling. It follows HDCP 2.2 and HDMI 2.0b specifications, including
supported data rates up to 18 Gbps, HDR (high dynamic range), 3D and HD
lossless audio formats.
With the built-in scaler, when connected to two different displays, the
corresponding HDMI output is capable of scaling down automatically (down to
1080P) to feed an optimal output signal to its attached display.
The splitter provides HDCP management which continuously authenticates HDCP
encryption between all devices, ensuring correct source content is output to each
display. It also features automatic input cable equalization, actively conditions
input HDMI signals to compensate for signal loss when using long cables or
cascading multiple units.
