What Is the UHD-808VW?
The OREI UHD-808VW is an 18Gbps 8x8 seamless UHD HDMI matrix with video wall support, audio extraction / insertion, IR matrix routing, RS-232 control, TCP/IP control, Web control, and PC tool control. It allows you to connect up to eight HDMI source devices and route them to up to eight HDMI displays.
The UHD-808VW can work as a standard 8x8 matrix, where each display can show the same or different HDMI source. It can also be configured for one or more video wall layouts using the PC tool or RS-232 control.
The UHD-808VW supports HDMI 2.0, HDCP 2.2, 18Gbps video bandwidth, seamless switching, video resolutions up to 3840x2160@60Hz and 4096x2160@60Hz, EDID management, output scaling, IR matrix routing, HDMI audio extraction, external L/R audio insertion, and control through the front panel, RS-232, TCP/IP, LAN, Web interface, and PC software.
The UHD-808VW is useful for professional AV systems, control rooms, restaurants, sports bars, retail displays, command centers, conference rooms, classrooms, houses of worship, and video wall installations where multiple HDMI sources need to be routed to multiple displays.
IMPORTANT — UHD-808VW Is a Matrix and Video Wall Controller
The UHD-808VW is not just a basic HDMI splitter.
It is an 8-input, 8-output HDMI matrix that can route any input to any output.
It also supports video wall configuration, allowing selected outputs to be grouped together as one large display wall.
This makes the product useful for both normal HDMI routing and advanced multi-screen display setups.
IMPORTANT — UHD-808VW Supports Seamless Switching
The UHD-808VW supports seamless switching.
This means switching between HDMI sources is designed to happen faster and more smoothly than a basic HDMI matrix, reducing the long black-screen delay that can happen with standard HDMI switching.
This is useful in commercial displays, control rooms, live presentation spaces, and video wall environments where switching speed matters.
IMPORTANT — UHD-808VW Supports 4K@60Hz, Not 8K or 4K@120Hz
The UHD-808VW 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-808VW 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 — Audio Insert Works Only in Specific Conditions
The UHD-808VW supports external L/R audio insertion.
However, the manual notes that analog audio input is only available when the corresponding video input is a DVI signal.
For example, if HDMI Input 1 is being used as a DVI signal, the matrix can use Analog Audio Input 1 as the audio source for that input.
For normal HDMI sources with embedded HDMI audio, the matrix can use the HDMI embedded audio.
IMPORTANT — IR Matrix Routing Follows Video Routing
The UHD-808VW supports IR matrix routing.
IR routing follows the video routing.
For example, if HDMI Input 3 is routed to HDMI Output 1, then the IR signal from the Output 1 location can be routed back to the IR output for Input 3.
This allows users near the display to control the source device assigned to that display when the IR receiver and blaster are properly installed.
IMPORTANT — Web / PC Tool Control Requires Network Setup
The UHD-808VW supports network control through LAN and Web control.
The factory default network setting listed in the manual is:
| Setting | Default Value |
| IP Type | Static IP |
| Static IP | 192.168.0.247 |
| Subnet Mask | 255.255.255.0 |
| Gateway | 192.168.0.1 |
The computer and matrix must be on the same network segment for network control to work.
For example, if the matrix IP is 192.168.0.247, the computer should be set to an IP address in the same range, such as 192.168.0.xxx.
IMPORTANT — PC Tool Has Default Login Passwords
Before using the PC tool, a password is required.
Default PC tool passwords:
| Account | Default Password |
| Administrator | 111111 |
| User | 000000 |
The Administrator account has access to all features.
The User account has access to all features except the OSD function.
