UHDS-202 Overview and Use Cases – OREI

What Is the UHDS-202?

The OREI UHDS-202 is an 18Gbps 2x2 HDMI matrix switcher with audio extraction. It allows you to connect up to two HDMI source devices and route them to two HDMI displays.

The UHDS-202 can work as both a matrix and a splitter. This means Output A and Output B can each show a different HDMI source, or both outputs can show the same HDMI source at the same time.

The UHDS-202 supports HDCP 2.2 / HDCP 1.x, DVI 1.0, with a video bandwidth of 18Gbps. It supports video resolutions up to 4K@60Hz YCbCr 4:4:4, HDR, HDR10+, HLG, Dolby Vision, EDID selection, IR remote control, and audio extraction from Output A through Optical and 3.5mm analog audio outputs.

The UHDS-202 is useful for home theater, gaming, office, classroom, conference room, and AV setups where two HDMI sources need to be shared between two displays.

IMPORTANT — UHDS-202 Is a Matrix, Not Just a Splitter

The UHDS-202 is a 2-input, 2-output HDMI matrix.

This means either HDMI input can be routed to either HDMI output.

For example:

Output A can show Input 1
Output B can show Input 2

You can also route the same input to both outputs if you want both displays to show the same source.

This makes the UHDS-202 more flexible than a basic HDMI splitter.

IMPORTANT — Audio Extraction Comes From Output A Only

The UHDS-202 includes Optical and 3.5mm analog audio outputs.

However, the manual notes that the audio output signal comes from Output A.

This means the Optical and L/R audio outputs follow the source selected for Output A, not Output B.

If the customer is not hearing the expected audio, confirm which source is currently selected on Output A.

IMPORTANT — 3.5mm L/R Output Supports PCM 2.0 Only

The 3.5mm analog L/R output supports analog stereo PCM 2.0 only.

If you are using the 3.5mm output and there is no audio, set the HDMI source device to PCM, LPCM, or Stereo audio.

The 3.5mm output does not support Dolby, DTS, Dolby TrueHD, DTS-HD, or other surround audio formats.

IMPORTANT — Optical Output Has Format Limits

The Optical output supports LPCM 2.0 / 2.1CH, Dolby 5.1, Dolby TrueHD, Dolby DD+, DTS 5.1, DTS-ES 6, DTS-HDMA 5.1, and DTS HD-HRA 5.1 as listed in the manual.

The connected soundbar, AVR, amplifier, or audio system must support the selected audio format.

If there is no audio from the Optical output, try setting the source device audio output to PCM stereo or a compatible Dolby/DTS format supported by the connected audio system.

IMPORTANT — UHDS-202 Supports 4K@60Hz, Not 8K or 4K@120Hz

The UHDS-202 supports video resolutions up to 4K@60Hz YCbCr 4:4:4.

It does not support 8K or 4K@120Hz.

For 8K or 4K@120Hz setups, use an HDMI 2.1 matrix or switch that supports the required bandwidth.

IMPORTANT — EDID Mode Affects Resolution and Audio Output

The UHDS-202 includes three EDID modes:

AUTO
COPY
STD

EDID tells the source device what video and audio format to send.

If you experience no video, no audio, wrong resolution, or compatibility issues, changing the EDID selector may help.

Use STD mode for troubleshooting because it forces fixed 1080p@60Hz EDID with PCM 2.0 audio.

Step-by-Step Setup

Connect the included 5V/1A power adapter to the DC 5V port on the UHDS-202.
Connect your HDMI source devices to HDMI Input 1 and HDMI Input 2.
Examples include a Blu-ray player, DVD player, PS4, Xbox, PC, laptop, streaming device, or cable box.
Connect HDMI Output A and HDMI Output B to your TVs, monitors, or projectors.
If using audio extraction, connect your audio device to either:
- Optical output for Optical/TOSLINK audio systems
- 3.5mm L/R output for analog stereo speakers or amplifier
Turn on the source devices, displays, audio system, and UHDS-202.
Use the Output A and Output B buttons on the front panel to select which input appears on each output.
Use the included IR remote if you want to switch inputs from a distance.
Set the EDID selector to AUTO, COPY, or STD depending on your setup.
If using 3.5mm analog audio, set the source device audio output to PCM or Stereo.

HDMI Cable Requirement — Critical

For best performance, use Premium High Speed HDMI cables.

The manual lists the following HDMI cable length guidance:

Video Resolution	Recommended Maximum HDMI Cable Length
4K@60Hz / 8-bit YCbCr 4:4:4	5m
4K@30Hz / 8-bit	10m
1080p@60Hz / 8-bit	15m

Poor-quality or longer HDMI cables may cause:

No video output
Flickering
Black screen
Audio dropouts
HDR or Dolby Vision issues
4K@60Hz not displaying correctly
HDCP handshake problems

For troubleshooting, test the source directly with the display and try a shorter HDMI cable.

Understanding Matrix Routing

The UHDS-202 allows either input to be assigned to either output.

Output	Available Source Options
Output A	Input 1 or Input 2
Output B	Input 1 or Input 2

This means both displays can show the same source, or each display can show a different source.

Example:

Output	Selected Source
Output A	Input 1
Output B	Input 2

Understanding Splitter Mode

The UHDS-202 can also be used like a splitter.

To do this, select the same input for both Output A and Output B.

Example:

Output	Selected Source
Output A	Input 1
Output B	Input 1

This sends the same HDMI source to both connected displays.

Understanding EDID Modes

The UHDS-202 includes AUTO, COPY, and STD EDID modes.

EDID Mode	Function
AUTO	Compares Output A and Output B EDID settings and sends the lowest compatible resolution to the source devices
COPY	Copies the EDID from the display connected to Output A. If Output A EDID is not detected, it copies Output B
STD	Sends fixed 1080p@60Hz EDID with PCM 2.0 audio to all HDMI outputs

Use AUTO when both displays should receive a compatible signal.

Use COPY when you want the source to follow the capability of the display connected to Output A.

Use STD for troubleshooting or when using older 1080p displays or stereo-only audio systems.

Understanding Audio Extraction

The UHDS-202 can extract audio from Output A and send it to external audio systems.

Output	Supported Audio	Best Used For
HDMI Output A / B	PCM 2.0 / 5.1 / 7.1CH, Dolby 5.1, DTS 5.1, Dolby TrueHD, DTS-HD	TVs, AVRs, HDMI audio systems
Optical Output	LPCM 2.0 / 2.1CH, Dolby 5.1, Dolby TrueHD, Dolby DD+, DTS 5.1, DTS-ES 6, DTS-HDMA 5.1, DTS HD-HRA 5.1	Optical soundbars, AVRs, amplifiers
3.5mm L/R Output	Analog stereo PCM 2.0	Stereo speakers, analog amplifiers, headphones with proper adapter

Important: Optical and 3.5mm audio extraction follow Output A only.

Understanding the IR Remote

The included IR remote can control power and input selection for Output A and Output B.

Remote Button	Function
Power	Powers on the product or sets it to standby
Output A 1 / 2	Selects Input 1 or Input 2 for Output A
Output A Cycle	Cycles Input 1 or Input 2 for Output A
Output B 1 / 2	Selects Input 1 or Input 2 for Output B
Output B Cycle	Cycles Input 1 or Input 2 for Output B

The manual recommends using the IR remote within 0–7m and within approximately ±45 degrees.
