Setup Guide
System Requirements
- Operating System: Windows, macOS, Android, Nintendo Switch, Xbox, PS5.
- Port: Laptop/device must have a fully functional USB-C port (supporting DisplayPort Alternate Mode and Power Delivery) or an HDMI port with a USB-A port for power.
Connection Instructions
- Unfold the Extender: Carefully unfold the Maxfree screen extender to its desired position. The integrated stand will support the screens.
- Connect via USB-C (Recommended): If your laptop has a full-featured USB-C port, connect the provided USB-C to USB-C cable from your laptop to the extender's USB-C port. This single cable can provide both video signal and power.
- Connect via HDMI + USB-A (Alternative): If your laptop does not have a full-featured USB-C port, connect the provided HDMI cable from your laptop's HDMI port to the extender's HDMI port. Then, connect a USB-A to USB-C cable from your laptop's USB-A port to the extender's USB-C port for power.
- Power On: The extender should power on automatically once connected. If not, press the power button on the extender.
- Driver Installation (Windows Only): For Windows systems, when connecting to the internet, drivers may need to be installed. Follow any on-screen prompts for a simple plug-and-play experience.

Display Modes
Your Maxfree screen extender supports various display modes:
- Extend Mode: Expands your desktop across multiple screens, allowing for more workspace. This is the default and most common mode for productivity.
- Mirror Mode (Duplicate): Duplicates your primary display onto the extender, showing the same content on both screens. Useful for presentations or sharing content.
Adjusting Display Settings
You can adjust display settings through your operating system:
- Windows: Right-click on the desktop > Display settings. Here you can arrange displays, change resolution, orientation, and scale.
- macOS: Go to Apple menu > System Settings (or System Preferences) > Displays. You can arrange displays, set resolution, and choose between extended or mirrored modes.
- Brightness/Contrast: Use the physical buttons on the side of the extender (if available) or adjust through your operating system's display settings.
Care and Maintenance
- Cleaning: Use a soft, lint-free cloth slightly dampened with water or a non-abrasive screen cleaner. Do not spray liquid directly onto the screen.
- Storage: When not in use, fold the extender to its compact form and store it in a dry, cool place away from direct sunlight.
- Handling: Avoid dropping or subjecting the extender to strong impacts. Do not place heavy objects on top of it.
