Alxum USB-C Wireless HDMI Transmitter & Receiver

This two-piece kit combines a transmitter and a receiver for a private, direct wireless link or lets the receiver function alone as an AirPlay/Miracast casting endpoint. Designed for modern laptops, tablets, and phones with full-function USB-C (DisplayPort Alt Mode), it removes the need for drivers or network setup when used in direct mode, while dual-band 5G+2.4G keeps connections stable in busy environments.

How do I set it up and start streaming?

Setup is designed to be fast: connect the transmitter to your USB-C device and the receiver to the display's HDMI input, then power both units. In the direct link mode the devices pair instantly—no app, password, or Wi‑Fi network required. For casting, put the receiver in receiver-only mode and use your phone or laptop’s AirPlay or Miracast function to send content.

• Plug the TX into a full-function USB-C port (DisplayPort Alt Mode).
• Connect RX to TV or projector HDMI and supply power via USB.
• Use direct link for driver-free streaming or RX-only for AirPlay/Miracast.
• No Bluetooth pairing or router configuration needed for direct mode.

What video quality and distance can I expect?

The kit prioritizes smooth 1080P at 60Hz playback over long distances using dual-band transmission to fight interference. You can reliably stream up to about 165 feet (50 meters) in open areas; performance in crowded indoor environments depends on obstacles and competing wireless signals. The system decodes 4K sources but outputs a stable 1080P@60Hz presentation to most displays.

• Stable 1080P@60Hz output for movies and presentations.
• Effective range up to 165ft/50m in open line-of-sight conditions.
• Dual-band 5G + 2.4G minimizes dropouts and interference.
• 4K input decoded to reliable 1080P output on connected displays.

Which devices and modes does the kit support?

It’s built for devices with a full-function USB-C port that supports DisplayPort Alt Mode—modern laptops and many phones and tablets. Use the kit as a two-piece transmitter/receiver set for the most stable connection, or use the receiver by itself to accept AirPlay or Miracast streams from compatible devices. Note that Google Cast (Chromecast) is not supported.

• Works with laptops, phones, tablets having USB-C with DisplayPort Alt Mode.
• Two modes: TX+RX direct link or RX-only AirPlay/Miracast casting.
• Does not support Google Cast/Chromecast protocol.
• No drivers required in direct connection mode—plug and play.

What design features help in real-world use?

The kit includes practical touches like a side-mounted USB-C port on the transmitter to avoid blocking adjacent laptop ports and a one-touch privacy button that immediately blanks the public screen. Its pocket-sized components make it easy to carry between meetings, classrooms, or outdoor gatherings, while the small form factor keeps cables and clutter to a minimum.

• Side-positioned USB-C port preserves neighboring ports on laptops.
• One-tap privacy button instantly hides displayed content when needed.
• Compact, lightweight pieces fit easily into a laptop bag or pocket.
• Ideal for quick transitions between meeting rooms and venues.

Who is this for? Professionals, educators, and content creators who need cable-free, reliable screen sharing will find this kit especially useful—whether you’re giving presentations in large rooms, extending your laptop display for multitasking, or wirelessly streaming media for backyard movie nights. If your device has a video-capable USB-C port and you value fast setup, stable 1080P performance, and a portable design, this Alxum kit simplifies connecting to TVs, projectors, and monitors without complex network setup.
