WHD-PRO2T-K Overview and Use Cases

What Is the WHD-PRO2T-K?

The OREI WHD-PRO2T-K is a 1080p wireless HDMI presentation system designed for BYOD meeting rooms, huddle rooms, classrooms, and collaboration spaces.

The kit includes two wireless Transmitters and one Receiver. Each Transmitter connects to a laptop or source device using HDMI and USB power. The Receiver connects to the display by HDMI. Once connected, users can press the Transmitter button to wirelessly mirror their screen.

The WHD-PRO2T-K supports wireless HDMI transmission up to 1080p@60Hz, 2-to-1 split-screen display, plug-and-play casting with no app required for the included HDMI Transmitters, iOS / Android / Mac / Windows support, Wi-Fi display, up to 100ft / 30m line-of-sight wireless range, up to 32 wireless Transmitters with one Receiver when additional Transmitters are added, and latency up to 200ms.

The WHD-PRO2T-K is useful for BYOD meetings, conference rooms, training rooms, classrooms, huddle rooms, collaboration spaces, and shared displays where multiple users need to present wirelessly without changing HDMI cables.

IMPORTANT — WHD-PRO2T-K Is a Wireless Presentation System

The WHD-PRO2T-K is different from a basic wireless HDMI extender.

It is designed for meeting-room presentation and screen sharing.

It supports:

IMPORTANT — Supports 1080p, Not 4K

The WHD-PRO2T-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 model that specifically supports 4K.

IMPORTANT — Two Transmitters Are Included

The package includes two WHD-PRO2T-K Transmitter units and one Receiver.

This allows two different users or laptops to be connected for wireless presentation.

The manual also lists support for up to 32 wireless Transmitters with one Receiver, but additional Transmitters are required.

IMPORTANT — 2-to-1 Split Screen Is Supported

The WHD-PRO2T-K supports 2-to-1 split-screen display.

This means two users can share content on the same display at the same time.

This is useful for:

1. Comparing documents
2. Side-by-side presentations
3. Team collaboration
4. Classroom sharing
5. Meeting-room discussions 
    
   Only up to two screens can be displayed at the same time. 
    
   If a third user wants to share, one of the first two users must stop sharing first.

IMPORTANT — Wireless Distance Is up to 100ft / 30m Line of Sight

The WHD-PRO2T-K supports wireless connectivity up to 100ft / 30m 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 manual lists latency as 200ms max.

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

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

IMPORTANT — Transmitter Requires USB Power

Each Transmitter requires USB power.

The manual states that the Transmitter requires USB 5V above 0.9A to start up.

For best results, connect the Transmitter USB cable to a USB 3.0 port or another USB power adapter that can provide enough power.

If the Transmitter turns on and off repeatedly, the USB port may not be providing enough power.

IMPORTANT — Receiver Requires DC 5V/2A Power

The Receiver uses the included DC 5V/2A power adapter.

Connect the Receiver to power before attempting to pair or cast.

If the Receiver does not start properly, check the DC power adapter and power connection.

IMPORTANT — Receiver Supports Wi-Fi Display From Mobile Devices

The Receiver can also support screen mirroring from mobile devices without using the included HDMI Transmitter.

Users can connect directly to the Receiver Wi-Fi.

Default connection information listed in the manual:

After connecting to the Receiver Wi-Fi, users can use the built-in screen mirroring function on compatible iOS, Android, Mac, or Windows devices.

IMPORTANT — Admin Web Settings Are Available

The WHD-PRO2T-K Receiver has a web settings page for advanced configuration.

Direct connection access:

After the first login, the system asks the user to change the admin password.

Important: Keep the new password safely. If the password is forgotten, hold the Receiver reset button for 10 seconds to restore default settings.

IMPORTANT — Wi-Fi or RJ45 LAN Can Be Used for Outbound Network

The Receiver supports Wi-Fi and RJ45 wired LAN.

The manual notes that outbound link can select only one:

The Receiver includes RJ45 Ethernet and supports 10/100/1000M Ethernet.

IMPORTANT — Pairing Is Usually Done Before Delivery

The manual states that the Receiver and Transmitters are already paired before delivery.

If there is no video signal, pairing can be done again by connecting the Transmitter USB-A cable to the USB port on the back of the Receiver.

The display will show “Pairing...” and then “Pairing OK” after successful pairing.

If a third user tries to share, the display will not show the third user until one of the existing users stops sharing.

Understanding Turn On / Turn Off Host Control Mode

The manual describes host control behavior:

The original factory setting is Off mode.

In Off mode, the host controls guest access.

Understanding the Receiver Main Screen

When the Receiver powers on successfully, the main screen appears on the display.

The main screen shows the WHD-PRO2T-K system interface and connection information.

Users can use this screen to confirm the Receiver is ready for wireless presentation.
