UHDS-1016 Overview and Use Cases

What Is the UHDS-1016?

The OREI UHDS-1016 is an 18Gbps 1x16 HDMI splitter. It distributes one HDMI source to as many as 16 HDMI displays simultaneously, with the same video and audio playing on every connected display.

The UHDS-1016 supports HDMI 2.0b, HDCP 2.2/1.x, resolutions up to 4K@50/60Hz 4:4:4, HDR, HDR10, HDR10+, HLG, Dolby Vision, multichannel HDMI audio, and advanced EDID management.

It is suitable for conference rooms, classrooms, restaurants, bars, digital signage, retail installations, control rooms, worship facilities, and other applications requiring one source on multiple screens.

IMPORTANT — UHDS-1016 Is a 1x16 HDMI Splitter

The UHDS-1016 mirrors one HDMI source. It cannot route independent sources or create separate computer desktops.

IMPORTANT — Supports 4K@60Hz 4:4:4

The source, HDMI cables, displays, and selected EDID mode must all support the required video format.

IMPORTANT — All Displays Show the Same Source

The UHDS-1016 sends the connected HDMI input to every active output.

When connected to a computer, the splitter duplicates the same screen on every display.

IMPORTANT — Downscaling Is Not Listed

The manual does not list automatic or manual 4K-to-1080p downscaling.

If the source outputs 4K, every connected display must support that signal. For mixed 4K and 1080p installations, select a compatible 1080p EDID mode so the source sends a resolution accepted by every display.

IMPORTANT — Advanced EDID Management

The UHDS-1016 includes a five-position EDID dial switch with 32 possible settings.

EDID determines which video resolution and audio capability the splitter reports to the HDMI source. Available modes include:

1. 1080i and 1080p
2. 1080p 3D
3. 4K@30Hz 4:4:4
4. 4K@60Hz 4:2:0
5. 4K@60Hz 4:4:4
6. Stereo Audio 2.0
7. Dolby/DTS 5.1
8. HD Audio 7.1
9. HDR modes
10. Copy Output 1
11. PC control mode 
     
    Select a mode supported by all connected displays and audio equipment.

Complete EDID Mode Table

Understanding Copy Output 1

EDID code 01010 copies the EDID from the display connected to HDMI Output 1.

Use this setting when:

1. Output 1 is connected to the primary display
2. The source should follow the primary display’s capabilities
3. Every other display supports the same resolution and audio format 
    
   If another display has lower capabilities than the Output 1 display, that display may not show video or play audio correctly.

Understanding PC Control Mode

EDID code 00000 is identified as PC control mode.

The manual does not provide software, connection instructions, or configuration procedures for this mode. The Micro-USB SERVICE port is described as a firmware update port.

Supported Color Depth and Color Space

Supported color spaces include:

1. RGB 4:4:4
2. YCbCr 4:4:4
3. YCbCr 4:2:2
4. YCbCr 4:2:0

Supported HDMI Audio

The selected EDID setting determines whether the source outputs stereo, Dolby/DTS 5.1, or HD Audio 7.1.

IMPORTANT — This Is Not an Audio Extractor

The UHDS-1016 passes audio through HDMI but does not provide separate audio extraction outputs.

Use a separate HDMI audio extractor if dedicated audio outputs are required.

Ports, Controls, and Indicators

Step-by-Step Setup

1. Turn off the HDMI source and displays.
2. Connect the HDMI source to the HDMI IN port.
3. Connect the primary display to HDMI OUT 1.
4. Connect additional displays to HDMI OUT 2 through HDMI OUT 16.
5. Set the EDID dial switch to a format supported by the connected equipment.
6. Connect the included 12V/2.5A locking power adapter.
7. Turn on the splitter using the front-panel POWER switch.
8. Turn on the displays and HDMI source.

Power Requirement — Critical

Use the included adapter or a compatible replacement with the correct voltage, polarity, connector, and current rating.

HDMI Cable Requirements

Use certified HDMI cables rated for the selected resolution.

Poor-quality or excessively long cables may cause:

1. No video
