Frequently Asked Questions

1. Why does my laptop show "NO Signal" when connected to L1 via the TYPE-C port?

This means your laptop’s TYPE-C port is likely not full-featured. A full-featured port supports both video signal and power transfer.

2. How can I determine if the TYPE-C interface of my laptop is full-featured?

Look for labels such as “DP” or “Thunderbolt 3/4” near the port. If none are visible, refer to your laptop manual or manufacturer website for confirmation.

3. My laptop has one full-featured TYPE-C interface and one HDMI port. How should I connect to L1?

You can either:
• Use a Type-C to Type-C cable to connect the full-featured port directly to L1.
• Use HDMI to Mini HDMI + a USB-C to USB-A cable for power.

4. Why does the screen flicker, disappear, and reconnect?

This occurs when your laptop can’t provide stable power. Use a 5V/2A (or higher) adapter for external power input to stabilize performance.

5. My laptop only has one TYPE-C port. How can I charge it while using TUTT L1?

Use a PD65W (or higher) adapter to power L1 via its Type-C port. The L1 will then charge your laptop while operating.
