TUTT L1 Portable Laptop Cellphone Monitor Extender 12.3" IPS FHD High Brightness Gaming Touchscreen Dual Speakers

High Brightness FHD IPS Screen

The TUTT L1 portable monitor boasts a 12.3” screen with 600 nits brightness and 1920×860 resolution, offering a wider and clearer viewing field with vibrant colors. Users can customize brightness, contrast, and backlight settings to optimize the experience in both extended and duplicate modes.

Touchscreen & Dual Surround Speakers

Featuring a responsive 10-point touch interface for Windows (1-point for Mac and Android), the L1 ensures seamless interaction. The dual stereo surround speakers deliver immersive audio, making it ideal for gaming, videos, and presentations. It serves both as a second screen for computers and a display for Android phones.

Detachable Stand & Wall Mount Compatibility

The included detachable stand supports multiple angles in horizontal and vertical orientations. With three rear stand slots and holes compatible with 100×100 / 75×75 / 50×50 wall mounts, users gain flexibility in positioning.

World of Connectivity

The monitor features multiple ports, including a Type-C port for single-cable video and power (requires a full-featured port). It supports switching between phone and computer modes and works with Hammer TNT, Huawei EMUI, and Samsung DEX. The Type-C supports PD60W fast charging, and a USB 2.0 port allows OTG expansion.

Professional After-Sales Service

Weighing just 2.3 pounds and 1 inch thick, the TUTT L1 is both compact and desktop-friendly. For any inquiries, contact our after-sales team through the seller profile. Please ensure your device has at least one full-function Type-C or HDMI port (with power supply) for proper connection.

Enhanced Viewing Experience

The FHD IPS panel and 600 nits brightness provide vivid colors, sharp details, and wide viewing angles, creating a rich visual environment.

Efficient and Convenient

Whether used as a second screen or smartphone extension, the L1 enhances multitasking with its touchscreen, dual speakers, connectivity, and portability.

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.
