StarTech.com 2 Port HDMI Splitter 4K60 HDR

The StarTech.com ST122HD202 is a compact 1x2 HDMI 2.0 splitter that duplicates a single HDMI source to two displays at true 4K 60Hz with HDR and up to 18 Gbps bandwidth.

Designed for reliable duplication of video and audio, this metal-housed HDMI splitter sends the same image and multi-channel audio to two screens simultaneously without introducing signal degradation. It supports HDMI 2.0 features such as 4:4:4 chroma, HDR, and HDCP 2.2 compatibility while remaining backward compatible with older HDMI displays. Passive cooling and plug-and-play setup make it practical for home theaters, digital signage, meeting rooms, and classrooms.

How does this splitter keep a clean 4K 60Hz picture?

The ST122HD202 maintains high-resolution output by supporting HDMI 2.0 bandwidth (up to 18 Gbps) and 4:4:4 chroma subsampling so color fidelity and pixel detail are preserved. HDR support increases dynamic range for brighter highlights and deeper shadows when connected displays accept HDR signals.

• Resolutions up to 4096x2160 at 60Hz
• 4:4:4 chroma for full color per pixel
• HDR pass-through for enhanced contrast and color
• Supports 7.1-channel audio including Dolby TrueHD and DTS-HD

Will it work with different HDMI devices I already own?

Yes — the splitter is broadly compatible with sources and displays. It supports HDCP 2.2 and will down-convert to older HDCP versions when needed, so Blu-ray players, gaming consoles, PCs, TVs, monitors, and many projectors are supported.

• HDCP 2.2 to 1.4 compatibility ensures wide device support
• Backward compatible with 4K30Hz and 1080p displays
• Works with both HDMI and HDMI-to-DVI displays (adapter required)
• Ideal for mixed-equipment digital signage deployments

How easy is setup and what about display settings?

Setup is plug-and-play: connect the source and two displays, power the splitter, and it will automatically pass EDID information from the display on port 1 to configure native resolution and refresh rate. An EDID emulation option simplifies matching the source and displays when different screen models are used across the outputs.

• Automatic EDID pass-through from display on port 1
• No drivers required — instant use after cable connections
• EDID emulation helps resolve resolution or refresh mismatches
• Passive cooling via durable metal housing for continuous operation

What length cables and distances are supported?

The splitter reliably carries signals up to about 5 meters (16.4 ft) using standard passive HDMI cables. For installations requiring longer runs, you can pair it with active HDMI cables or HDMI extenders (sold separately) to preserve 4K60 performance over extended distances.

• Passive cable reach: up to 5 m (16.4 ft) for 4K60
• Use active HDMI cables or extenders for longer distances
• Audio outputs active on both ports simultaneously
• Supports wide-screen monitor formats and HDMI/DVI compatibility

Who is this for? The StarTech.com ST122HD202 is suited for anyone who needs reliable, simultaneous 4K video distribution to two displays — such as small businesses running digital signage, presenters duplicating content in meeting rooms, educators sharing widescreen content in classrooms, or homeowners splitting a 4K source to a TV and projector. If you need straightforward duplication without scaling down image fidelity, this compact, metal-cased HDMI 2.0 splitter provides a robust, plug-and-play solution backed by a two-year StarTech.com warranty and free lifetime technical support.
