Special Note for MacBooks (M1/M2/M3 Chips) and Limited Ports
This product is not directly compatible with MacBooks equipped with M1, M2, or M3 chips without a specific adapter. If your laptop has an M1/M2/M3 chip, or if it has only one full-featured Type-C port and no HDMI port, or if it lacks a full-featured Type-C port and only has an HDMI port with multiple USB-A ports, you will need the H5-M cable (ASIN: B0DXL2C6WC) for proper functionality. The H5-M cable requires external power.

5. Operating Instructions

Adjusting Display Settings

6. Maintenance
Cleaning
To clean the screens, gently wipe them with a soft, lint-free cloth. For stubborn marks, dampen the cloth slightly with water or a screen-safe cleaning solution. Avoid using harsh chemicals or abrasive materials.
Storage
When not in use, store the screen extender in its travel bag to protect it from dust and scratches. Ensure it is stored in a cool, dry place away from direct sunlight.
7. Troubleshooting
- "No Signal" Displayed: If a "No Signal" message appears on one of the extended screens after connecting a Type-C cable, it indicates that your laptop's C port only supports power supply. In this case, you need to connect an additional HDMI cable to the display extender to provide a video signal. This means one side of the screen will require two cables for full functionality.
- Flickering/Black Screen/Power Saving Mode: If the screen flickers, goes black, or enters power-saving mode unexpectedly, your laptop's power or voltage may be insufficient to support three screens simultaneously. Connect an external 5V/4A power adapter to your laptop to ensure adequate power supply.
- General Connection Failure: Ensure all cables are securely connected to both the screen extender and your laptop. Verify that your laptop's ports are functioning correctly. Refer to the 'Connection Methods' section for proper wiring.
If you encounter persistent issues or have questions regarding connection, please contact the seller, POTTMACEE-US, for assistance. They typically respond within 12 hours.
