UHD-WPE165-K Overview and Use Cases

What Is the UHD-WPE165-K?

The OREI UHD-WPE165-K is an 18Gbps HDMI and USB-C extender kit with a wall plate Transmitter. It extends HDMI or USB-C video from a wall plate source location to a remote HDMI display over CAT5e / CAT6 cable.

The kit includes a wall plate Transmitter, Receiver, wallplate, mounting accessories, power adapter, and user manual. The source device connects to either the HDMI input or USB-C input on the wall plate Transmitter, the remote display connects to HDMI OUT on the Receiver, and a CAT5e / CAT6 cable connects the Transmitter to the Receiver.

The UHD-WPE165-K supports HDMI 2.0b, HDCP 2.2, DisplayPort 1.2a over USB-C, with a video bandwidth of 18Gbps through HDMI and 5.4Gbps through USB-C input. It supports video resolutions up to 4K@60Hz, HDR, HDR10, Dolby Vision pass-through, HDMI and USB-C input switching, USB-C laptop charging through the CHARGE port, and Power over Cable with the power adapter connected at the Receiver end. It extends 4K@24Hz up to 164ft / 50m and 4K@60Hz up to 115ft / 35m over CAT5e / CAT6 cable. 

The UHD-WPE165-K is useful for conference rooms, classrooms, training rooms, home theater setups, wall plate AV installations, offices, meeting spaces, and locations where HDMI or USB-C laptop video needs to be extended neatly from a wall plate to a display.

IMPORTANT — UHD-WPE165-K Has HDMI and USB-C Inputs

The UHD-WPE165-K wall plate Transmitter includes:

This makes the unit useful for modern rooms where users may connect either HDMI devices or USB-C laptops.

IMPORTANT — USB-C Input Requires Video Output Support

The USB-C port is used for video input from compatible USB-C source devices.

The connected laptop, tablet, or source must support video output over USB-C, commonly through DisplayPort Alt Mode.

If the USB-C source does not support video output, the Receiver display will not show video from that device.

IMPORTANT — USB-C CHARGE Port Is for Laptop Charging

The wall plate includes a USB-C CHARGE port.

This port is used to connect the USB-C power adapter from the laptop.

The manual notes that to charge the laptop while using the device, the USB-C power adapter must be connected to the USB-C CHARGE port.

The CHARGE port is not the same as the USB-C video input.

IMPORTANT — Supports 4K@60Hz

The UHD-WPE165-K supports video resolutions up to 4K@60Hz.

Supported resolutions include:

To use 4K@60Hz, the source device, display, HDMI cable, USB-C device capability, CAT cable, and video settings must all support 4K@60Hz.

IMPORTANT — Maximum Distance Depends on Resolution

The UHD-WPE165-K supports different transmission distances depending on the resolution.

For best performance, use high-quality CAT5e / CAT6 cable.

Poor cable quality, damaged connectors, poor terminations, or long HDMI cables can cause signal instability.

IMPORTANT — Use a Direct CAT Cable Connection

The UHD-WPE165-K must be connected directly from the wall plate Transmitter CAT6 OUT to the Receiver CAT IN.

Do not connect it through:

• Network switch 
• Router 
• Internet network 
• LAN switch 
• Home network 
• Office network 

The manual specifically states that this model cannot connect to a network and that the Transmitter and Receiver must be connected directly.

IMPORTANT — Power Adapter Connects at the Receiver End

The UHD-WPE165-K uses Power over Cable.

The power adapter connects to the Receiver DC 12V port.

The Receiver then provides power to the wall plate Transmitter through the CAT cable.

If the wall plate does not power on, check the Receiver power adapter and the CAT cable connection.

IMPORTANT — Automatic and Manual Input Switching Are Supported

The UHD-WPE165-K supports automatic and manual switching between HDMI and USB-C inputs.

Use the SOURCE button on the wall plate when manually switching between connected devices.

IMPORTANT — HDR10 and Dolby Vision Pass-Through Are Supported

The UHD-WPE165-K supports HDR10 and Dolby Vision pass-through.

To use HDR or Dolby Vision, the source device, display, content, HDMI cable, USB-C output mode, and CAT cable must support the required format.

If HDR does not work, test at 1080p first, then confirm source and display video settings.

IMPORTANT — HDMI Audio Format Support

The UHD-WPE165-K supports HDMI audio formats including:

• LPCM 
• Dolby Digital / Plus / EX 
• Dolby TrueHD 
• DTS 
• DTS-EX 
• DTS-96/24 
• DTS High Res 
• DTS-HD Master Audio 
• DSD 

The connected source and display or audio system must also support the selected audio format.

IMPORTANT — Receiver Has IR IN

The Receiver includes an IR IN port.

This allows an IR Receiver cable to be connected at the display side.

The manual lists IR IN on the Receiver side but does not list an IR OUT port on the wall plate Transmitter. For source-control setups, confirm the IR function and included cable configuration before installation.

IMPORTANT — No HDMI Loop Out

The UHD-WPE165-K does not list HDMI loop out on the wall plate Transmitter.

It is designed to send one selected wall plate input to one remote HDMI display through the Receiver.

If a local display is needed near the wall plate, use a different model with HDMI loop out or add a compatible splitter before the extender.

Ports and Panel Layout

Step-by-Step Setup

1. Install the wall plate Transmitter in the desired wall plate location. 
2. Connect CAT6 OUT on the Transmitter to CAT IN on the Receiver using CAT5e / CAT6 cable. 
3. Connect HDMI OUT on the Receiver to the TV, monitor, or projector. 
4. Connect the included DC 12V/1A power adapter to the Receiver. 
5. Connect an HDMI source device to the HDMI input on the wall plate if using HDMI. 
6. Connect a USB-C laptop or source device to the USB-C input on the wall plate if using USB-C video. 
7. If laptop charging is needed, connect the laptop’s USB-C power adapter to the USB-C CHARGE port. 
8. Power on the display and source device. 
9. Use the SOURCE button to select HDMI or USB-C input if needed. 
10. Check the HDMI LED, USB-C LED, Receiver power indicator, and data signal indicator. 
11. Test video, audio, and input switching. 

CAT Cable Requirement — Critical

Use high-quality CAT5e / CAT6 cable.

Poor CAT cable may cause:

• No video 
• Flickering 
• Black screen 
• Receiver data signal indicator not lighting 
• USB-C video not working 
• HDMI video not working 
• 4K@60Hz not working

• HDR issues 
• HDCP handshake problems 

For troubleshooting, test the source directly with the display before using the extender.

USB-C Requirement — Critical

The USB-C input must be connected to a source device that supports video output through USB-C.

If USB-C video does not work, check:

• Whether the laptop supports USB-C video output 
• Whether the USB-C cable supports video 
• Whether the USB-C input is selected 
• Whether the USB-C LED is active 
• Whether the same issue happens through HDMI input 

For laptop charging, connect the laptop’s USB-C power adapter to the CHARGE port.

Power Requirement — Critical

The power adapter connects to the Receiver.

If the Transmitter does not power on, check:

• Receiver power adapter 
• CAT cable
