What Is the UHD-44MVW?
The OREI UHD-44MVW is a 4x4 seamless HDMI matrix with video wall and multiview functionality. It allows you to connect up to four HDMI source devices to up to four HDMI displays, while also supporting advanced display layouts such as video wall and multiview modes.
The UHD-44MVW can work in three main ways:
- Matrix mode, where each display can show the same or different HDMI source
- Video wall mode, where multiple displays can combine to form a larger video wall
- Multiview mode, where multiple HDMI sources can be shown on one screen in different window layouts
The UHD-44MVW supports HDMI 2.0 and HDCP 2.2, with a video bandwidth of 18Gbps. It supports video resolutions up to 4K@60Hz, 12 multiview modes, 9 video wall modes, CEC control, advanced EDID management, Optical and L/R audio extraction, IR matrixing, RS-232 control, TCP/IP control, Web GUI control, front-panel control, and IR remote control.
The UHD-44MVW is useful for professional AV setups, control rooms, retail displays, restaurants, sports bars, classrooms, conference rooms, houses of worship, security monitoring rooms, and video wall installations.
IMPORTANT — UHD-44MVW Is a Matrix, Video Wall Controller, and Multiviewer
The UHD-44MVW is not just a standard HDMI switch.
It supports three major operating modes:
| Mode | What It Does |
| Matrix Mode | Routes any of the four HDMI inputs to any of the four HDMI outputs |
| Video Wall Mode | Combines multiple displays into layouts such as 2x2, 4x1, or 1x4 |
| Multiview Mode | Shows multiple HDMI sources together on a single display layout |
This makes the product useful for both normal HDMI routing and more advanced display processing.
IMPORTANT — UHD-44MVW Supports 4K@60Hz, Not 8K or 4K@120Hz
The UHD-44MVW 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 switch that supports the required bandwidth.
IMPORTANT — Video Wall Mode Is Not the Same as Computer Extended Desktop
The UHD-44MVW 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 display and process HDMI video signals across multiple displays. If a computer needs true extended desktop operation, the computer or graphics card must provide the required display outputs.
IMPORTANT — Multiview Mode Can Show Multiple Sources on One Screen
The UHD-44MVW supports multiview layouts, allowing multiple HDMI inputs to appear on one display.
Supported multiview categories include:
- Single
- PIP
- Dual
- Triple 1
- Triple 2
- Triple 3
- Quad 1
- Quad 2
- Quad 3
- User 1
- User 2
- User 3
This is useful when users want to monitor several sources at the same time on one screen.
IMPORTANT — Audio Output Has Multiple Modes
The UHD-44MVW includes external audio outputs and audio routing options.
The audio output can be configured in three modes:
| Audio Mode | Function |
| Bind to Input | Audio OUT 1–4 follows HDMI Input 1–4 |
| Bind to Output | Audio OUT follows the HDMI source routed to the matching HDMI Output |
| Audio Matrix | Any HDMI input audio can be routed to a selected audio output |
The manual also notes that embedded audio cannot be extracted to the audio out channel. This is important when using the analog audio input/embed function.
IMPORTANT — Web GUI Control Requires Network Setup
The UHD-44MVW can be controlled through a browser-based Web GUI using the TCP/IP port.
The default IP address is:
| Setting | Default Value |
| IP Address | 192.168.0.100 |
| Subnet Mask | 255.255.255.0 |
| Gateway | 192.168.0.1 |
| TCP/IP Port | 8000 |
| Telnet Port | 23 |
To access the Web GUI, connect the matrix to a PC or router and make sure the PC is on the same network segment.
The IP address can also be checked by pressing the INFO button on the remote, which displays the IP address and baud rate on screen.
Default Web GUI login:
| Username | Password |
| User | user |
| Admin | admin |
IMPORTANT — RS-232 and Web GUI May Take a Few Minutes After Power-On
The manual notes that RS-232 and Web GUI control become available a few minutes after the device is powered on.
If RS-232 or Web GUI control does not respond immediately after startup, wait a few minutes and try again.

- If using IR matrix control, connect IR receiver cables to IR INPUT ports and IR blaster cables to IR OUTPUT ports.
- If using Web GUI control, connect the TCP/IP port to a router or PC using a network cable.
- If using RS-232 control, connect the RS-232 port to a PC or control system.
- Turn on the source devices, displays, audio system, and UHD-44MVW.
- Use the front-panel buttons, IR remote, Web GUI, or RS-232 commands to choose Matrix, Video Wall, or Multiview mode.
HDMI Cable Requirement — Critical
For best performance, use Premium High Speed HDMI cables.
The manual recommends the following HDMI cable lengths:
| Video Resolution | Recommended HDMI Cable Length |
| 4K60 | 5m / 16ft |
| 4K30 | 10m / 32ft |
| 1080p60 | 15m / 50ft |
Poor-quality or longer HDMI cables may cause:
- No video
- Flickering
- Black screen
- Audio dropouts
- HDCP handshake issues
- Video wall display problems
- Multiview display issues
- 4K@60Hz not working properly
For general use, the FAQ recommends using high-quality HDMI cables under 30 feet.

Example:
| Output | Selected Source |
| Output 1 | Input 1 |
| Output 2 | Input 2 |
| Output 3 | Input 3 |
| Output 4 | Input 4 |
You can also route the same input to all outputs.
To route a source using the front panel or remote, select the output first, then select the input.
Example: Press OUTPUT 2, then press INPUT 3 to route Input 3 to Output 2.

| 1x2-2 | Alternate two-display vertical layout |
| 3x1 | Three-display horizontal layout |
| 4x1 | Four-display horizontal layout |
| 1x3 | Three-display vertical layout |
| 1x4 | Four-display vertical layout |
Video wall mode can be selected using the front-panel buttons, Web GUI, or RS-232 commands.
The product also supports bezel adjustment from 0 to 10 for horizontal and vertical bezel correction.
Understanding Multiview Mode
Multiview mode allows multiple HDMI sources to be shown together in one display layout.
Supported multiview modes include:

| User 3 | User-defined custom layout |
In user-defined multiview modes, windows can be dragged, resized, assigned different inputs, maximized by double-clicking, and restored by double-clicking again through the Web GUI.
Understanding EDID Management
The UHD-44MVW includes 18 EDID modes.
| EDID Mode | Description |
| 1 | 4K60, 2.0CH |
| 2 | 4K60, 5.1CH |
| 3 | 4K60, 7.1CH |
| 4 | 4K30, 2.0CH |

| 6 | 4K30, 7.1CH |
| 7 | 1080p, 2.0CH |
| 8 | 1080p, 5.1CH |
| 9 | 1080p, 7.1CH |
| 10 | WUXGA, 2.0CH |
| 11 | 768p, 2.0CH |
| 12 | XGA, 2.0CH |
| 13 | User 1 |
| 14 | User 2 |
| 15 | Copy Output 1 |
| 16 | Copy Output 2 |
| 17 | Copy Output 3 |
| 18 | Copy Output 4 |
EDID can be configured using the front panel, Web GUI, or RS-232 commands.
Use 2.0CH modes for stereo audio systems.
Use 5.1CH or 7.1CH modes only when the connected audio system supports those formats.
Use Copy Output modes when you want the source to follow the capability of a specific connected display.
Understanding Audio Routing
The UHD-44MVW supports HDMI audio, analog audio input embedding, Optical audio output, and L/R analog audio output.
The Web GUI includes an Audio page with the following options:
| Audio Option | Function |
| HDMI Original Audio | Uses the audio from the HDMI input |
| Embed Audio | Uses the analog audio input and embeds it with the HDMI input |
| Bind to Input | Audio OUT 1–4 follows HDMI Input 1–4 |
| Bind to Output | Audio OUT 1–4 follows HDMI Output 1–4 |
| Audio Matrix | Allows any input audio to be routed to any external audio output |
Important: The manual notes that embedded audio cannot be extracted to the audio out channel.
Understanding IR Matrix Control
The UHD-44MVW supports one-way IR control.
The IR matrix follows the HDMI matrix routing.
For example, if HDMI Input 3 is routed to HDMI Output 1, the IR signal from the IR receiver near Output 1 can be sent to the IR blaster near Input 3. This allows the user near the TV connected to Output 1 to control the source device connected to Input 3.
IR remote distance:
| IR Method | Distance |
| Front IR window, direct facing | Up to 8m |
| Front IR window, ±45° angle | Up to 5m |
| IR EXT receiver, direct facing | Up to 5m |
| IR EXT receiver, ±45° angle | Up to 3m |
If the matrix is installed in a cabinet, use the included IR receiver cable connected to the IR EXT port.
Understanding Web GUI Control
The Web GUI allows advanced setup and control from a browser.
Through the Web GUI, users can:
