WHD-AIR Overview and Use Cases

What Is the WHD-AIR?

The OREI WHD-AIR is a Full HD wireless display receiver designed for wireless screen mirroring and presentations from phones, tablets, laptops, and computers.

The WHD-AIR connects to a TV, monitor, or projector through HDMI and allows compatible iOS, Android, macOS, and Windows devices to mirror or cast content wirelessly. It is useful for business conferences, education, training, home entertainment, and general wireless display use.

The WHD-AIR supports up to 1920x1080@60Hz output resolution, IEEE 802.11ac dual-band 2.4GHz / 5GHz Wi-Fi, H.264 compression, Miracast, AirPlay, Wireless Display, HDMI 1.2, HDCP 1.3, USB-C power input, plug-and-play setup, and wireless transmission up to 100ft line of sight. The manual lists latency as up to 0.2 seconds.

IMPORTANT — WHD-AIR Is a Wireless Display Receiver

The WHD-AIR is not a traditional HDMI extender kit with a separate Transmitter and Receiver.

It is a wireless display receiver.

It connects to the display by HDMI, then compatible phones, tablets, laptops, and computers connect wirelessly to mirror or cast content.

It supports:

IMPORTANT — Supports 1080p, Not 4K

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

It does not support:

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

IMPORTANT — This Product Is Receiver Only

The package includes:

There is no separate HDMI transmitter included.

Users connect wirelessly from supported phones, tablets, laptops, or computers.

IMPORTANT — Power Adapter Is Not Included

The package includes a USB-A to USB-C cable, but the manual does not list a power adapter in the package contents.

The WHD-AIR can be powered using:

1. TV USB port
2. USB power adapter
3. Other USB power source 
    
   The Receiver requires DC 5V / 0.5A power. 
    
   If the Receiver fails to start, turns on and off repeatedly, or behaves unstable, use a stronger USB power source or USB power adapter.

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

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

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

Walls, cabinets, metal objects, Wi-Fi routers, microwaves, air conditioners, and other wireless interference can reduce range and stability.

IMPORTANT — This Is Not Zero-Latency

The WHD-AIR has wireless transmission latency.

The manual lists latency as up to 0.2 seconds.

This is suitable for:

1. Meetings
2. Presentations
3. Classroom use
4. Training
5. Photo sharing
6. File sharing
7. General screen mirroring
8. Home entertainment 
    
   It is not ideal for fast gaming, live performance monitoring, or applications that require instant response.

IMPORTANT — Supports AirPlay and Miracast / Wireless Display

The WHD-AIR supports multiple wireless display methods.

For best results, the phone, tablet, or computer must support the correct wireless display method.

IMPORTANT — Some Paid Streaming Apps May Not Work

The manual notes that some subscription-based paid apps with HDCP copyright protection may not be supported.

Examples listed include:

1. Netflix
2. Amazon Prime Video
3. Hulu
4. Comcast TV
5. DIRECTV
6. Xfinity
7. Vudu 
    
   This is due to app-level or HDCP copyright protection and does not necessarily mean the WHD-AIR is defective.

IMPORTANT — Only One Device Can Mirror at a Time

The WHD-AIR can mirror one device at a time.

If another phone, tablet, or computer needs to connect, the current device must stop mirroring first.

IMPORTANT — Receiver Can Connect to Wi-Fi for Internet Access

When a phone, tablet, or computer connects directly to the WHD-AIR Wi-Fi, the device may lose normal internet access.

To keep internet access while mirroring, connect the WHD-AIR and the casting device to the same home or office Wi-Fi network through the web settings page.

The manual lists the web settings IP as:

IMPORTANT — Corporate Wi-Fi May Require IT Support

If the WHD-AIR cannot join a corporate Wi-Fi network, the manual recommends contacting the IT department.

The IT team may need to check:

2. Microwaves
3. Air conditioners
4. Other wireless devices
5. Walls
6. Metal objects
7. Covered Receiver
