HDS-808 Overview and Use Cases

What Is the HDS-808?

The OREI HDS-808 is a 4K@30Hz 8x8 HDMI matrix. It allows up to eight HDMI source devices to be routed to up to eight HDMI displays.

The HDS-808 can send any HDMI input to any HDMI output. This means each display can show the same source or a different source depending on the routing setup.

The HDS-808 supports HDMI 1.4 and HDCP 2.2, with a video bandwidth of 10.2Gbps. It supports video resolutions up to 4K@30Hz, 4K to 1080p downscaling on each output, advanced EDID management, Web GUI control, RS-232 control, IR remote control, and up to 8 saved preset scenes. It supports HDMI audio formats including LPCM 2.0/5.1/7.1, Dolby Digital, DTS 5.1, Dolby Digital Plus, Dolby TrueHD, DTS-HD Master Audio, Dolby Atmos, and DTS:X. 

The HDS-808 is useful for home theaters, offices, conference rooms, classrooms, restaurants, sports bars, retail displays, showrooms, and commercial AV setups where multiple HDMI sources need to be routed to multiple HDMI displays.

IMPORTANT — HDS-808 Is a Matrix, Not a Basic Splitter

The HDS-808 is an 8-input, 8-output HDMI matrix.

This means any of the eight HDMI inputs can be routed to any of the eight HDMI outputs.

For example:

• Output 1 can show Input 1 
• Output 2 can show Input 4 
• Output 3 can show Input 8 
• Output 4 can show Input 2 

You can also route the same HDMI input to multiple outputs or all outputs.

This is different from a basic HDMI splitter, which only duplicates one source to multiple displays.

IMPORTANT — HDS-808 Support 4K@30Hz, Not 4K@60Hz or 8K

The HDS-808 supports video resolutions up to 4K@30Hz.

It does not support 4K@60Hz, 4K@120Hz, or 8K.

For 4K@60Hz systems, use an HDMI 2.0 matrix.

For 8K or 4K@120Hz systems, use an HDMI 2.1 matrix.

IMPORTANT — Each Output Supports 4K to 1080p Downscaling

The HDS-808 supports 4K to 1080p downscaling on each output.

This is useful when some displays support 4K@30Hz and other displays only support 1080p.

For example, if Output 1 is connected to a 4K TV and Output 2 is connected to a 1080p TV, the scaler can help the 1080p display receive a compatible signal.

Downscaling does not upgrade 1080p to 4K. It only reduces a 4K signal to 1080p for compatibility with lower-resolution displays.

IMPORTANT — HDS-808 Does Not Have Separate Audio Extraction Ports

The HDS-808 supports HDMI audio pass-through, but it does not include separate Optical, Coaxial, RCA, 3.5mm, or analog audio extraction outputs.

Audio passes through HDMI to the connected TV, monitor, projector, AVR, or HDMI audio system.

If separate audio extraction is required, use a matrix model with built-in audio extraction outputs.

IMPORTANT — Web GUI Requires Network Setup

The HDS-808 can be controlled through a browser-based Web GUI using the LAN port.

The default IP address is 192.168.0.100.

To access the Web GUI, the computer must be on the same network segment as the matrix.

For example, if the matrix IP address is 192.168.0.100, set the computer IP address to something like 192.168.0.120.

IMPORTANT — EDID Settings Affect Video and Audio Compatibility

The HDS-808 includes advanced EDID management.

EDID tells the HDMI source what video and audio formats the system supports.

If you experience no signal, audio issues, wrong resolution, or compatibility problems, changing the EDID setting may help.

Use 1080p EDID modes for older displays, 4K@30Hz EDID modes for 4K displays, and Copy Output modes when you want the source to follow the capability of a specific display.

Ports and Panel Layout

Step-by-Step Setup

1. Connect the included 12V/2.5A power adapter to the HDS-808. 
2. Connect your HDMI source devices to HDMI Input 1 through HDMI Input 8. 
   Examples include a DVD player, Blu-ray player, streaming device, PC, cable box, satellite receiver, set-top box, or media player. 
3. Connect HDMI Output 1 through HDMI Output 8 to your TVs, monitors, projectors, or commercial displays. 
4. Turn on the HDMI source devices, displays, and HDS-808. 
5. Use the front-panel buttons or IR remote to route each input source to the desired output. 
6. If one or more displays do not support 4K, use the output scaler setting to downscale 4K to 1080p for those outputs. 
7. Set EDID based on your required video and audio format. 
8. If using Web GUI control, connect the LAN port to a computer or network and make sure the computer is on the same IP range as the matrix. 
9. If using RS-232 control, connect the RS-232-IN port to a PC or control system. 
10. Save routing presets if the same display layouts will be used again. 

HDMI Cable Requirement — Critical

For best performance, use Premium High Speed HDMI cables.

The manual lists the following HDMI cable length guidance:

Poor-quality or longer HDMI cables may cause:

• No video output 
• Flickering 
• Black screen 
• Signal dropouts 
• Audio dropouts 
• HDCP handshake issues 
• 4K@30Hz not displaying correctly 
• Output not detected 
• Source not detected 

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

Understanding Matrix Routing

The HDS-808 allows any HDMI input to be routed to any HDMI output.

This allows each display to show a different source, or multiple displays to show the same source.

Example:

Understanding Front-Panel Switching

To route a source from the front panel:

1. Press the desired INPUT button first. 
2. Press the desired OUTPUT button second. 

Example:

To send Input 2 to Output 1 and Output 2:

1. Press INPUT 2. 
2. Press OUTPUT 1. 
3. Press OUTPUT 2. 

The selected input button lights green, and the LCD screen shows the selected channel information.

Understanding Presets

The HDS-808 supports up to 8 saved preset scenes.

Presets allow you to save common routing layouts and recall them later.

Example:

If you want to save the current routing as Preset 1, press SAVE + OUTPUT 1.

If you want to recall Preset 1 later, press RECALL + OUTPUT 1.

This is useful for conference rooms, sports bars, classrooms, and commercial displays where the same layouts are used repeatedly.

Understanding Downscaling

The HDS-808 supports 4K to 1080p downscaling on each output.

Scaler modes include:

Use 4K → 1080p when a 4K source is connected but one display only supports 1080p.

Use Bypass when the connected display supports the source resolution.

Use Auto when you want the output to follow the connected display’s EDID.

EDID Settings

The HDS-808 includes 22 EDID modes.

Use 1080p EDID modes for older displays or troubleshooting.

Use 4K2K30 EDID modes for 4K@30Hz displays.

Use 5.1CH or 7.1CH EDID modes only when the connected audio system supports those formats.

Use Copy Output modes when you want the source device to follow the capability of a specific connected display.

Note: If copying EDID from an output that is not connected to a display, the matrix will not update the EDID and will continue using the previous EDID.

Understanding Web GUI Control

The HDS-808 supports browser-based Web GUI control.

The Web GUI can be used to:

• View device status 
• View firmware version 
• View hostname 
• View network configuration 
• View temperature and uptime 
• Route HDMI inputs to outputs 
• Send one input to all outputs 
• Save, recall, and clear up to 8 presets 
• Rename inputs and outputs 
• Check input signal status 
• Set EDID modes 
• Upload user-defined EDID files 
• Download EDID files 
• Check output cable status 
• Set output scaler mode 
• Turn output stream on or off 
• Change network settings 
• Change Web GUI passwords 
• Lock or unlock front-panel buttons 
• Turn beep on or off 
• Set LCD display time 
• Change RS-232 baud rate 
• Update firmware 
• Factory reset or reboot the device 

Understanding Network Setup

The default IP address is 192.168.0.100.

To access the Web GUI:

1. Connect the LAN port of the HDS-808 to a PC or network. 
2. Set the PC IP address to the same network segment. 
3. If the matrix IP is 192.168.0.100, set the PC IP to 192.168.0.120. 
4. Enter the matrix IP address into a browser. 
5. Log in using the default credentials. 

Default Web GUI login:

The current IP address can also be checked through RS-232 by sending the command get ip addr.

Understanding the IR Remote

The included IR remote can control input/output routing, EDID settings, save presets, and recall presets.

The number buttons follow a logical sequence. In stateless mode, pressing a number first enters input selection mode, and pressing another number selects the output.

RS-232 Control

The HDS-808 supports RS-232 command control through the rear DB9 RS-232-IN port.

Default RS-232 settings:

RS-232 commands can control:

• Power on/off 
• Reboot 
• Factory reset 
• Front-panel lock 
• Beep on/off 
• Device temperature 
• Uptime 
• Control ID 
• LCD logo text 
• EDID settings 
• User-defined EDID 
• Input HDCP
