Introduction

This 4K HDMI splitter lets you connect your HDMI video source to four HDMI displays, with support for Ultra HD resolutions and HDR (High Dynamic Range) as well as 7.1 surround sound audio.

Unlike many 4K splitters that only support a 30Hz refresh rate, this splitter works with 4K HDMI 2.0 displays with output resolutions of up to 3840 x 2160p at 60Hz.

Supports true 4K at 60Hz
Not all 4K splitters are created equal. While some HDMI 1.4 splitters can achieve 4K resolutions, they'll only work at a 30Hz refresh rate. Other HDMI 1.4 splitters are marketed as 4K at 60Hz, but their color data is reduced to a lower 4:2:0 chroma subsampling. This drastically reduces color quality in order to achieve 4K at 60Hz resolution, even with limited HDMI 1.4 bitrate capabilities.

This 4K 60Hz HDMI splitter offers full support for your HDMI 2.0 equipment, including true 4K resolution at 60Hz. For smoother video and color transitions, the splitter offers 4:4:4 chroma subsampling, meaning every pixel gets its own unique color. Support for HDMI 2.0 devices means this splitter can transmit bandwidth up to 18Gbps, making it the ideal solution for high-resolution tasks requiring the highest color detail.

Widely compatible
The splitter supports HDCP 2.2 and is backward compatible with 4K 30Hz and 1080p displays. This ensures that it will work with lower resolution displays such as TVs or projectors around your site or in your digital signage application.

Easy installation and setup
For hassle-free setup, the 4K HDMI splitter offers easy plug-and-play installation with no additional software or drivers required. The splitter passes EDID between your video source and the display attached to port 1, ensuring native settings such as resolution and refresh rate are configured automatically.

Mounting hardware is also included, for a tidy and professional installation.

The ST124HD20 is backed by a 2-year StarTech.com warranty and free lifetime technical support.
