ATEN VS4812 2-Port 4K HDMI Splitter

Overview

The ATEN VS4812 is a 2-port 4K HDMI splitter designed to duplicate a single HDMI source signal to two displays. This device is essential for scenarios where a high-resolution video feed, such as from a security camera system or a digital signage player, needs to be simultaneously presented on multiple monitors without signal degradation. It supports 3840x2160 resolution at 60Hz with 4:4:4 color sampling, ensuring image fidelity for critical viewing applications. The VS4812 model is powered via USB-C, simplifying setup in environments where dedicated power outlets may be scarce.

Compatibility

This HDMI splitter is compatible with any HDMI source device outputting up to 3840x2160 @ 60Hz (4:4:4) and any HDMI display capable of receiving that signal. It functions as a passive signal duplicator, meaning it does not rely on specific brand compatibility for the source or displays, provided the HDMI standard is met. For optimal performance with the specified 4K @ 60Hz (4:4:4) resolution, ensure your HDMI cables are certified for High Speed with Ethernet and do not exceed the 3-meter maximum distance specified for each output run.

Installation Notes

The VS4812 requires a 5V/1A power input via its USB-C port, supplied by the included 1-meter USB Type-C to Type-A cable. Connect this cable to a powered USB port on your source device or a dedicated USB power adapter. HDMI output runs should not exceed 3 meters to maintain signal integrity at 3840x2160 @ 60Hz (4:4:4). The splitter itself is designed for rack mounting, though specific rack ear dimensions are not detailed in the provided specifications.
