## Long description

The StarTech.com ST122HD4KU HDMI Splitter duplicates a single HDMI audio/video source to two HDMI displays and supports Ultra HD 4K resolution (3840 x 2160 at 30Hz). The compact splitter includes a built-in HDMI source cable and can be powered via a nearby USB port or an AC adapter, enabling flexible installation for presentations, signage, or multi-display setups.
Advantages
This 2-port HDMI splitter supports 4K video while remaining backward compatible with 1080p and 720p devices, and it also supports 3D formats. The integrated HDMI source cable removes the need for an additional input cable and the unit can be powered either from a USB port or using the supplied power adapter for reliable operation. Its compact, black enclosure and lightweight design make it simple to integrate into existing AV arrangements.
Suitable for
Connecting one HDMI source to two HDMI displays for presentations or meetings

How to use
Connect the built-in HDMI source cable to your HDMI output device (for example a Blu-ray player, computer or set-top box). Attach up to two HDMI displays to the splitter's HDMI output ports. Power the splitter by plugging the supplied USB cable into a nearby USB port or by connecting the included AC adapter to mains power. Once connected, ensure your source device is configured for the desired resolution; the splitter will mirror the source signal to both displays.
Usage recommendations
For stable 4K output, use high-quality HDMI cables for the connected displays and set the source device to 3840 x 2160 @ 30Hz. If displays show different EDID information, set all devices to a common resolution to avoid signal mismatch. Use the AC adapter for longer-term or critical installations where USB power may be insufficient.
