A wireless display adapter is a receiver that plugs into a TV, monitor, or projector and lets a compatible phone, tablet, or computer send its screen to that display without a video cable. Many use Miracast: the sender and receiver connect wirelessly, while the adapter feeds the display through HDMI and usually draws power from USB. Both devices must support the same projection method; an adapter does not make every device or streaming dongle compatible.
How a wireless display adapter works
Miracast is a wireless display standard based on Wi-Fi Direct. It creates a peer-to-peer connection between the device sending its screen and the receiver. The adapter then passes that screen output to the TV or monitor through its HDMI connection. Microsoft’s Miracast documentation describes the standard and its Wi-Fi Direct basis.
This is screen projection, often called mirroring: the display shows output from the sending device. The word “casting” on a product label does not prove that it supports Miracast. Check the wireless display standard supported by both the sender and receiver.
What you need to use one
- A sender device—such as a laptop, phone, or tablet—that supports the receiver’s wireless display method. For a Miracast adapter, the sender must support Miracast.
- A receiver adapter compatible with the sender and its operating system. Compatibility can differ between adapter models and generations.
- A display with a suitable input, commonly HDMI, plus a power source for the adapter. Microsoft’s Wireless Display Adapter connects to HDMI and draws power from USB; see Microsoft’s setup and compatibility instructions.
Protected content can have additional requirements. Microsoft notes that full functionality is not available with non-HDCP devices for certain versions of its adapter, so check the exact model’s documentation if you intend to display protected video.

- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
How to connect a Miracast adapter
- Plug the adapter’s HDMI connector into the TV, monitor, or projector.
- Connect its USB power lead to a USB charging port or another suitable USB power source. USB provides power; HDMI carries the display connection.
- Use the display’s input controls to select the HDMI input where the adapter is connected.
- On a compatible Windows PC, press Windows+K, then select the wireless display adapter. On another Miracast-enabled device, open its wireless display, Miracast, or Cast settings and follow the device’s connection instructions.
If the adapter does not appear, first verify that the sending device supports Miracast. Microsoft provides Windows compatibility and connection guidance in Fix connections to wireless displays or docks in Windows. If the device lacks Miracast support, a wired connection or a different solution compatible with that device may be needed.

- Resolution and features: Verify the model’s stated output capabilities and any protected-content requirements, including HDCP where applicable.

Wireless display adapter vs. other streaming devices
A Miracast wireless display adapter receives screen projection from a compatible device. Do not assume that an HDMI streaming dongle or a product marketed for “casting” supports Miracast: products can use different standards and methods. Check the adapter’s specifications against the sending device’s supported wireless display options before buying.
