• Difficult cable routing across rooms
• Limited mobility during presentations
• Extra adapters for USB-C devices
• Difficulty connecting smartphones or tablets to large displays
• Complicated wireless display setup

Smart Solution for Wireless Screen Sharing

The UGREEN 75500 Wireless USB-C Transmitter & HDMI Receiver creates a direct wireless connection between a compatible USB-C source and an HDMI display.

Simply connect the transmitter to the source device and the receiver to the HDMI display. Once powered and connected, the two units can automatically pair and transmit the source screen wirelessly.

This makes the system useful for meetings, classrooms, presentations, home entertainment and other situations where a direct HDMI cable would be inconvenient.

Key Features

1. 1080P@60Hz Full HD Wireless Transmission

The UGREEN 75500 supports video transmission up to 1920 × 1080 at 60Hz.

This provides Full HD image quality with smooth 60Hz video for presentations, videos, screen sharing and compatible multimedia applications.

2. 5.8GHz Wireless Transmission

The system uses a 5.8GHz wireless connection designed to provide stable video transmission while reducing interference compared with crowded lower-frequency wireless environments.

This makes it suitable for offices, classrooms, meeting rooms and home entertainment setups.

3. Up to 50m Transmission Range

The UGREEN S309/75500 is listed with a transmission distance of up to approximately 50 meters under open and unobstructed conditions.

Actual range can be lower when walls, furniture, other wireless devices or structural obstacles are present.

Important: The 50m figure should be treated as a maximum laboratory/open-space specification rather than a guaranteed indoor operating distance.

4. Magnetic Storage Design

The transmitter and receiver feature a magnetic design that allows the two pieces to attach together when not in use.

This helps:

• Keep the set organized
• Reduce the chance of losing one component
• Make transportation easier
• Minimize accessory clutter

The magnetic construction is one of the distinguishing features of the 75500.

5. Plug-and-Play Operation

The UGREEN 75500 is designed for simple setup without requiring a dedicated application or complicated wireless-network configuration.

The transmitter and receiver automatically establish their wireless connection, allowing users to begin screen transmission with minimal setup.

6. USB-C DP Alt Mode Compatibility

The transmitter connects through USB-C and requires the source device to support DisplayPort Alt Mode / USB-C video output.

Compatible source devices can include supported:

• Smartphones
• Tablets
• Laptops
• MacBooks
• PCs
• Cameras
• Other USB-C devices with video-output capability

A USB-C port that only supports charging or data transfer will not provide video output.

7. HDMI Receiver for Large Displays

The receiver uses an HDMI connection for the display side.

It can connect to compatible:

• TVs
• Computer monitors
• Projectors
• HDMI-equipped displays

This allows a small USB-C device to send its screen to a larger display without requiring a long physical HDMI cable.

8. Mirror & Extended Display Modes

The 75500 is listed with support for screen mirroring and extended-display use on compatible computer systems.

This allows the external display to be used for presentations, second-screen workflows and compatible desktop applications.

The exact display modes available depend on the operating system and source device.

9. Audio & Video Synchronization

The UGREEN S309/75500 supports synchronized audio and video transmission, with specifications listing up to 48kHz / 24-bit audio sampling.

This makes it suitable for presentations, videos and other multimedia content where synchronized sound and image are important.

10. Compact & Portable Design

The system weighs approximately 90g, making it convenient to carry in a laptop bag, backpack or travel case.

Its compact magnetic design is particularly useful for users who frequently move between meeting rooms, classrooms, offices or different entertainment setups.

How to Use UGREEN 75500

Step 1: Check Your USB-C Port

Step 5: Wait for Automatic Pairing

The transmitter and receiver are designed to pair automatically without requiring a dedicated application or router configuration.

Step 6: Select Your Display Mode
