- Connect your second HDMI source device (e.g., streaming box, PC) to the other input port on the UHDS-212.
- Connect the output port of the UHDS-212 to the HDMI input of your display (TV or monitor).
- Ensure all devices are powered on.

This diagram illustrates the bi-directional functionality of the OREI HDMI switch. It shows the 1x2 setting (one source to two displays, toggling between them) and the 2x1 setting (two sources to one display, toggling between them).
Important Cable Length Considerations
- For 4K@60Hz resolution, do not use HDMI cables longer than 10 feet (approximately 3 meters). For optimal performance, it is recommended to use 1.5-meter cables on each port.
- For lower resolutions like 4K@30Hz or 1080p@60Hz, use HDMI cables less than 15 feet (approximately 4.5 meters) on each port.
Operation
The OREI UHDS-212 features a simple push-button operation to switch between inputs or outputs.

The central button on the OREI UHDS-212 allows users to easily switch between connected HDMI sources or displays.
Switching Inputs/Outputs
Once all devices are connected and powered on, simply press the button on the top of the UHDS-212 unit to cycle through the available HDMI inputs (in 2x1 switch mode) or outputs (in 1x2 splitter mode). An LED indicator will show which input/output is currently active.
Driver Installation (for PC/Mac Extended Display)
For certain operating systems, especially when utilizing extended display functionality with a PC or Mac, driver installation may be required. Please visit the official SiliconMotion website for the latest drivers compatible with your operating system.
Note: This device will not extend the monitor for PC or laptops in a true multi-monitor setup. It allows you to toggle between displays or sources. It also does not extract audio.
