What Is the WHD-PRO100-K?

The OREI WHD-PRO100-K is a 1080p wireless HDMI sender and receiver kit that sends HDMI video and audio wirelessly from one HDMI source to one HDMI display.

The kit includes a Transmitter dongle and Receiver box. The Transmitter connects to the HDMI output on the source device, the Receiver connects to the HDMI input on the display, and the signal is sent wirelessly between both units.

The WHD-PRO100-K supports wireless HDMI transmission up to 1080p, 3D HDTV signals over HDMI, HDCP compliance, room-to-room HD wireless transmission, and up to 100ft line-of-sight wireless range. The manual lists latency as less than 300ms.

The WHD-PRO100-K is useful for home theaters, cross-room wireless HDMI, meeting rooms, game rooms, projector setups, and situations where running a long HDMI cable is not practical.

 

IMPORTANT — WHD-PRO100-K Supports 1080p, Not 4K

The WHD-PRO100-K supports wireless HDMI transmission up to 1080p.

It does not support:

  1. 4K
  2. 4K@60Hz
  3. 4K@120Hz
  4. 8K 
     
    For 4K wireless HDMI, use a wireless extender model that specifically supports 4K.

 

IMPORTANT — Wireless Distance Is up to 100ft Line of Sight

The WHD-PRO100-K supports wireless transmission up to 100ft line of sight.

Line of sight means the best performance is achieved when there is a clear path between the Transmitter and Receiver.

Walls, furniture, AV racks, metal objects, Wi-Fi routers, microwaves, air conditioners, and other wireless interference can reduce the working distance.

The manual also notes that the optimum indoor range is less than 100ft.

 

IMPORTANT — This Is Not Zero-Latency

The WHD-PRO100-K has wireless transmission latency.

The manual lists latency as less than 300ms.

This is acceptable for many home theater, meeting room, presentation, and general video applications.

It is not ideal for fast gaming, live performance monitoring, or applications that require instant response.

 

IMPORTANT — IR Function Is Not Available on This Model

The manual specifically notes that the IR function is not available on the WHD-PRO100 Transmitter box.

This model does not support IR remote extension.

If IR control is needed, use a wireless HDMI model that includes IR pass-through.

 

IMPORTANT — Pairing May Be Needed

If there is no video signal, the Transmitter and Receiver may need to complete pairing.

The manual says to:

  1. Press the Pairing key once on the Receiver box.
  2. Wait for the pairing message on the screen.
  3. Press the Pairing key once on the Transmitter stick.
  4. Wait for the connection to establish automatically.

 

IMPORTANT — Transmitter Power May Need Extra USB Power

The Transmitter uses a Type-A USB to Micro USB Y-type power cable.

If the USB port on the source device does not provide enough power, the manual recommends connecting another DC 5V/1A AC power adapter to the Transmitter power connector.

Insufficient power may cause:

  1. No video
  2. Pairing issues
  3. Wireless dropouts
  4. Unstable video
  5. Transmitter not powering correctly

 

IMPORTANT — Receiver Requires DC 5V/1A Power

The Receiver uses the included DC 5V/1A Micro USB power adapter.

If the Receiver does not power on, confirm that the Micro USB power cable and power adapter are connected properly.

Step-by-Step Setup

  1. Connect the WHD-PRO100-K Transmitter to the HDMI output on the source device. 
    Examples include a notebook, satellite receiver, CATV set-top box, Blu-ray player, PS4, PS3, Xbox, streaming device, or media player.
  2. Connect the Y-type USB power cable to the Transmitter Micro USB power port.
  3. Connect the Receiver HDMI OUT to the display using an HDMI cable. 
    Examples include an HDTV, monitor, or projector.
  4. Connect the included DC 5V/1A power adapter to the Receiver Micro USB power port.
  5. Power on the HDMI source and display.
  6. Select the correct HDMI input on the display.
  7. Wait for the Transmitter and Receiver to connect.
  8. If no video appears, press the Pairing key on the Receiver first, then press the Pairing key on the Transmitter.

 

Wireless Signal Requirement — Critical

For best performance, keep the Transmitter and Receiver within 100ft line of sight.

Wireless performance may be affected by:

  1. Walls
  2. Cabinets
  3. Metal objects
  4. AV racks
  5. Wi-Fi routers
  6. Microwaves
  7. Air conditioners
  8. Other wireless devices
  9. Long distance between units 
     
    If the video is unstable, move the Transmitter and Receiver closer together, reduce obstacles, and adjust their direction for better reception.

 

HDMI Cable Requirement — Critical

Use a High Speed HDMI cable from the Receiver to the display.

Poor HDMI cables may cause:

  1. No picture
  2. No sound
  3. Intermittent signal
  4. HDCP handshake issues
  5. 3D signal problems
  6. Unstable video 
     
    For troubleshooting, test the source directly with the display first.

 

Power Requirement — Critical

Use proper power for both units.

Unit Power Requirement
Transmitter Type-A USB to Micro USB Y-type power cable
Receiver DC 5V/1A Micro USB power adapter

If the source USB port cannot provide enough power to the Transmitter, use a DC 5V/1A power adapter.

 

Understanding the Transmitter

The Transmitter is the HDMI stick-style unit that connects to the HDMI output on the source device.

It has:

  1. HDMI connector
  2. Micro USB power input
  3. Pairing button 
     
    The Transmitter sends the HDMI signal wirelessly to the Receiver.

 

Understanding the Receiver

The Receiver is installed near the remote display.

It has:

  1. HDMI OUT
  2. Micro USB power input
  3. Pairing button 
     
    The Receiver receives the wireless HDMI signal and sends it to the TV, monitor, or projector through HDMI.

 

Understanding Pairing Mode

Use pairing mode when the Receiver does not show video.

Pairing steps:

Step Action
1 Press Pairing once on the Receiver box
2 TV screen shows “Connecting through Pairing ...”
3 Press Pairing once on the Transmitter stick
4 Connection should establish automatically

After pairing is complete, the display should show the wireless video signal.

 

Understanding LED Indicators

Condition Transmitter LED Receiver LED TV Screen
