UHD-416MVW Overview and Use Cases

What Is the UHD-416MVW?

The OREI UHD-416MVW is a 4K@60Hz 4x16 HDMI matrix with seamless switching, video wall, multiview, and audio extraction. It allows up to four HDMI source devices to be routed across up to sixteen HDMI displays.

The UHD-416MVW can work as a standard HDMI matrix, where each output can show a selected HDMI source. It can also be used for video wall layouts and multiview layouts, making it useful for large display installations that need flexible source routing, screen splicing, and multi-source viewing.

The UHD-416MVW supports HDMI 2.0 and HDCP 2.2, with a video bandwidth of 18Gbps. It supports video resolutions up to 3840x2160@60Hz and 4096x2160@60Hz, seamless switching, multiview functionality, video wall functionality, 180-degree image rotation, output resolution scaling, EDID management, LAN control, RS-232 control, PC tool control, and 3.5mm / Optical audio extraction. 

The UHD-416MVW is useful for sports stadiums, conference rooms, control rooms, retail displays, houses of worship, command centers, classrooms, showrooms, and large-scale commercial AV installations.

IMPORTANT — UHD-416MVW Is a Matrix, Video Wall Processor, and Multiviewer

The UHD-416MVW is not just a basic HDMI switch or splitter.

It supports three main functions:

This makes the product useful for both standard HDMI routing and advanced multi-screen display setups.

IMPORTANT — UHD-416MVW Supports 4K@60Hz, Not 8K or 4K@120Hz

The UHD-416MVW supports video resolutions up to 4K@60Hz.

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

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

IMPORTANT — Video Wall Mode Is Not the Same as Computer Extended Desktop

The UHD-416MVW can create video wall layouts across multiple connected displays.

However, it is not a computer docking station or KVM switch, and it does not create a multi-monitor extended desktop from one computer by itself.

Video wall mode is used to process and display HDMI video across multiple screens. If a computer needs true extended desktop operation, the computer or graphics card must provide the required display outputs.

IMPORTANT — Multiview Video Wall Has Special Limitations

The UHD-416MVW supports multiview video wall layouts, but there are important limitations.

The product supports four groups of multiview outputs:

If one output in a multiview group is enabled as multiview, the other three outputs in that group display the same content with the same output resolution.

For a multiview video wall, the manual notes that multiview must be enabled on Output 13, and the multiview layout for the video wall is controlled through Output 13.

IMPORTANT — Multiview Video Wall Supports Up to 12 Screens

If a video wall works in multiview mode, the maximum screen number is 12.

This is because Outputs 13, 14, 15, and 16 must work in multiview mode and cannot be part of the video wall outputs.

For non-multiview video wall setups, the total screen count can use up to 16 outputs.

IMPORTANT — Input 4 Has a Limitation in Multiview Video Wall Mode

If a video wall is working in multiview mode, Input 4 cannot be used as a source for standalone output display or non-multiview video wall display.

This is important for installations that use both:

• One multiview video wall 
• Another non-multiview video wall 
• Standalone outputs 

In that case, Input 4 is reserved for the multiview video wall behavior and cannot be selected for the other display groups.

IMPORTANT — Audio Extraction Uses One 3.5mm / Optical Output

The UHD-416MVW includes one LR / Optical audio output port.

This port can connect to an audio device such as a soundbar, AVR, amplifier, or audio system.

The PC tool includes Audio Switching, which allows the installer to choose which input audio is sent out through the 3.5mm / Optical output.

The listed audio format is LPCM 2.0.

If there is no audio from the 3.5mm / Optical output, set the source audio to PCM / LPCM stereo.

IMPORTANT — PC Tool Is Required for Advanced Setup

The UHD-416MVW can be controlled through PC software using LAN or RS-232.

The PC tool is used for:

• Matrix routing 
• Audio switching 
• EDID read/write 
• Signal configuration 
• Output resolution settings 
• Video wall setup 
• Multiview setup 
• Scene save/load 
• Network settings 
• Firmware information 
• Factory reset 

The initial PC tool login password is:

IMPORTANT — LAN Control Requires Network Setup

The default LAN settings listed in the manual are:

To use network control, the computer and matrix must be on the same network segment.

For example, if the matrix IP address is 192.168.0.247, the computer should use an IP address in the same range, such as 192.168.0.xxx.

Ports and Panel Layout

Step-by-Step Setup

1. Connect the included AC power cord to the UHD-416MVW. 
2. Connect your HDMI source devices to HDMI Input 1 through HDMI Input 4.

10. For multiview setup, enable multiview mode for the required output in Signal Config, then configure the layout in the Multiview section. 
11. Save scenes if the same routing, video wall, or screen layout will be used again. 

HDMI Cable Requirement — Critical

For best performance, use high-quality HDMI cables rated for HDMI 2.0 and 18Gbps bandwidth.

Poor-quality or long HDMI cables may cause:

• No video output 
• Flickering 
• Black screen 
• Signal dropouts 
• HDCP handshake issues 
• 4K@60Hz not working 
• Video wall alignment issues 
• Multiview display issues 
• Audio dropouts 
• Seamless switching problems 

For troubleshooting, test each source directly with each display, try shorter HDMI cables, and lower the output resolution temporarily.

Understanding Matrix Routing

The UHD-416MVW allows any of the four HDMI inputs to be routed to any of the sixteen HDMI outputs.

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

Understanding Front-Panel Switching

To switch a source from the front panel:

1. Press the desired Output button. 
2. Press the desired Input button. 
3. Press ENTER. 

Example:

2. Press Input 2. 
3. Press ENTER. 

To route one input to all outputs:

1. Press ALL. 
2. Press the desired Input button. 
3. Press ENTER. 

Example:

Press ALL → Input 1 → ENTER to send Input 1 to all outputs.

Understanding the IR Remote

The included remote can control input/output routing, one-to-one switching, one-to-all switching, scene save, and scene recall.

Remote switching examples:

Because the remote has output buttons 1–9 and 0, scenes and remote output shortcuts are accessed using those available keys.

Understanding Scene Save and Recall

The UHD-416MVW can save and recall display scenes.

A scene can store the current routing and screen layout.

Front-panel example:

The PC tool supports saving and loading up to 30 scenes.

Scenes are useful for installations that need different modes such as:

• Presentation mode 
• Video wall mode 
• Sports mode 
• Monitoring mode 
• Event mode 
• Standalone display mode 

Understanding Output Resolution Scaling

The UHD-416MVW supports 21 default output resolutions, plus Auto and User Define resolution.

Use 4K output modes only when the display and cable support 4K.

Use 1080p or lower output modes for older displays or troubleshooting.

Use USER or AUTO for LED wall or sender card applications when custom output resolution matching is required.

EDID Settings

The UHD-416MVW supports EDID control through the PC tool and front-panel EDID button.

The PC tool can:

• Read EDID from an output port 
• Save EDID to a file 
• Open a saved EDID file 
• Write EDID to an input port 
• Save written EDID as User EDID 

Basic EDID process in the PC tool:

1. Select an output port. 
2. Click Read to read EDID from the connected display. 
3. Click Save if you want to store that EDID file. 
4. Select the input port. 
5. Click Write to write the EDID to that input. 

Use EDID management when:

• A display does not show video 
• The wrong resolution appears 
• A source does not detect the display correctly 
• An LED sender card needs pixel-to-pixel setup 
• A custom display resolution is required 

Understanding Video Wall Mode

The UHD-416MVW supports video wall splicing through the PC tool.

Basic video wall setup:

1. Open the PC tool. 
2. Connect through RS-232 or LAN. 
3. Go to the TV Wall section. 
4. Set how many outputs will be used for the video wall. 
5. Select the number of rows and columns. 
6. Drag-select the screens that should be used for the video wall. 
7. Right-click and select Screen Splicing. 
8. Use Input Select to choose the source for the video wall. 
9. Use Output Select to assign output ports to screen positions. 
10. Enable Sync Delay if needed for synchronized video wall display. 
11. Set bezel configuration if needed. 
12. Save the scene if the layout will be used again. 

The product can support different video wall layouts such as 3x3, 3x4, 3x5, 4x4, and other layouts within the 16-output limit.

Understanding Bezel Configuration

The UHD-416MVW supports pixel-based bezel configuration.

This allows the installer to set:

• Left edge 
• Right edge 
• Up edge 
• Bottom edge 

Bezel correction helps align the image across display borders so the video wall looks more natural.

After entering bezel values, click Write for the settings to take effect.

Understanding Sync Delay

The TV Wall section includes Sync Delay.

Sync Delay helps make sure all video wall outputs run in sync.

This can help avoid timing mismatch between displays in a video wall.

The manual notes that if the resolution of an output port is changed, the device should be repowered to ensure spliced screens work synchronously.

Understanding Output Rotation

The UHD-416MVW supports output rotation settings.

Available rotation options include:

This is useful when some displays are physically mounted upside down in a video wall installation.

The manual lists video wall functionality with 180-degree rotation.

Understanding Multiview Mode

The UHD-416MVW supports multiview functionality.

Multiview allows multiple HDMI input sources to appear together on a display layout.

Before configuring multiview, the output must be set to Multiview mode in the Signal Config page.

Important notes:

• The top layer is Layer 4 
• The bottom layer is Layer 1 
• Multiview windows can be configured in the Multiview section 
• Each window can have video source, audio source, layer layout, and window display on/off settings 
• If an output port is part of a video wall, the video wall must be disabled before changing that output to Multiview 

Understanding Multiview Window Roaming

The UHD-416MVW supports multiview window roaming.

This allows multiview windows to be positioned flexibly, especially when used together with video wall mode.

This is useful when sources need to appear in custom window positions rather than fixed quad or split-screen layouts.

Understanding Multiview Video Wall Setup

For a multiview video wall, the manual notes that Output 13 must be used for multiview layout control.

The basic behavior is:

1. Set Output 13 to Multiview mode. 
2. Configure the multiview layout on Output 13. 
3. In TV Wall settings, enable MV Input. 
4. The video wall can use the multiview layout controlled from Output 13. 

Important limitation: When MV Input is enabled, Input 4 cannot be selected for Output 1–12. Instead, the multiview content shown on Output 13 is used for the multiview wall behavior.

Understanding PC Tool Control

The UHD-416MVW PC tool includes the following sections:

The PC tool is installation-free software.

Initial login password:

Understanding Audio Switching

The UHD-416MVW includes audio switching in the PC tool.

Audio Switching allows the user to choose which input audio is sent out through the 3.5mm / Optical output.

This is useful when the audio output needs to follow a specific HDMI source instead of every output individually.

The listed audio format is LPCM 2.0, so the source should be set to PCM / stereo for best compatibility.

Understanding LED Panel / Sender Card Setup

The manual includes a setup process for LED panel or sender card use.

Basic process:

1. Connect one matrix input to a source device using HDMI. 
2. Connect one matrix output to the LED panel / sender card using HDMI. 
3. Use the PC tool to read the EDID of the LED panel / sender card. 
4. Download or write this EDID to the matrix input port. 
5. Set the output resolution to USER or AUTO. 
6. If using USER, configure the user-defined resolution to match the physical resolution of the LED panel unit. 

This is useful for pixel-to-pixel LED wall display setups.

Understanding MultiPanel Function

The MultiPanel function is used when LED splicing panel units have different width or height.

Basic process:
