WHD-PRO1T-K Overview and Use Cases

What Is the WHD-PRO1T-K?

The OREI WHD-PRO1T-K is a 1080p wireless HDMI presentation system designed for meeting rooms, classrooms, BYOD collaboration, and wireless screen sharing.

The kit includes one wireless Transmitter and one Receiver. The Transmitter connects to a laptop or HDMI source device, and the Receiver connects to a display using HDMI or VGA. The user can press the Transmitter button to start, pause, or resume screen sharing.

The WHD-PRO1T-K supports up to 1920x1080@60Hz output resolution, HDMI and VGA display output, 2.4GHz / 5GHz dual-band Wi-Fi, H.264 compression, Miracast, AirPlay, macOS, Windows, iOS, iPadOS, and Android. It supports wireless transmission up to 100ft line of sight and latency up to 0.2 seconds. The Receiver also includes a 3.5mm stereo audio output for use with VGA display setups.

The WHD-PRO1T-K is useful for conference rooms, huddle rooms, classrooms, training rooms, presentations, education, entertainment, and group BYOD meetings where users need to share screens wirelessly without installing drivers or software.

IMPORTANT — WHD-PRO1T-K Is a Wireless Presentation System

The WHD-PRO1T-K is different from a basic wireless HDMI extender.

It is designed for screen sharing and BYOD meetings.

It supports:

IMPORTANT — Supports 1080p, Not 4K

The WHD-PRO1T-K supports output resolution up to 1920x1080@60Hz.

It does not support:

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

IMPORTANT — Receiver Has HDMI and VGA Outputs

The Receiver includes:

1. HDMI output
2. VGA output
3. 3.5mm stereo audio output 
    
   This allows the WHD-PRO1T-K to work with both newer HDMI displays and older VGA displays. 
    
   Important: The manual states that HDMI and VGA outputs cannot be used at the same time. 
    
   Use either:

IMPORTANT — VGA Output Needs 3.5mm Audio

VGA carries video only.

If using VGA output, connect the Receiver 3.5mm stereo audio output to speakers, amplifier, or the display’s audio input.

If using HDMI output, audio passes through HDMI to the display.

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

The WHD-PRO1T-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, cabinets, metal objects, Wi-Fi congestion, microwaves, air conditioners, and other wireless interference can reduce range and stability.

IMPORTANT — This Is Not Zero-Latency

The WHD-PRO1T-K has wireless transmission latency.

The manual lists latency as less than or equal to 0.2 seconds.

This is suitable for meetings, presentations, education, document sharing, and general wireless screen mirroring.

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

IMPORTANT — Up to 32 Transmitters Can Pair With One Receiver

The WHD-PRO1T-K supports up to 32 Transmitters paired to one Receiver.

Additional Transmitters are sold separately.

Only one Transmitter can mirror at a time. To mirror from another Transmitter, the current Transmitter must stop mirroring first.

IMPORTANT — Transmitter May Need USB-C Power

The Transmitter connects to the source using HDMI, but some computers may not provide enough power through HDMI.

If the Transmitter does not power on or does not work properly, connect the included USB-A to USB-C cable to power the Transmitter.

Power options:

The Transmitter requires DC 5V/0.9A power.

IMPORTANT — Receiver Requires DC 5V/2A Power

The Receiver must be powered using the included DC 5V/2A power adapter.

Connect the USB-C power cable to the Receiver and then connect the adapter to a wall outlet.

After powering the Receiver, press the power button on the side of the unit.

IMPORTANT — No Drivers or Software Required

The WHD-PRO1T-K does not require driver or software installation for the included Transmitter.

Connect the Transmitter to the laptop or HDMI source, power the Receiver, and press the Transmitter button to start screen sharing.

For phone/tablet casting, use compatible built-in screen mirroring functions such as AirPlay or Miracast.

IMPORTANT — Supports AirPlay and Miracast

The WHD-PRO1T-K supports wireless streaming protocols:

For mobile casting, connect the device to the Receiver’s Wi-Fi SSID shown on the display, then select the Receiver using the device’s screen mirroring function.

IMPORTANT — Admin Web Settings Are Available

The WHD-PRO1T-K Receiver has a web settings page.

When connected directly to the Receiver Wi-Fi, open a browser and enter:

The settings menu can be used for:

1. Internet settings
2. Resolution
