How to Connect a Dual Screen Portable Monitor to a Laptop with the H5 Converter Cable

This guide explains how to connect compatible TUTT dual screen portable monitors to a laptop using a full-featured USB-C connection, HDMI, or the included H5 converter cable. The correct setup depends on the available ports on your laptop and whether your device supports video output through USB-C or Thunderbolt.

Dual Screen Portable Monitor H5 Converter Cable MacBook M-Series Support External Power Recommended Compatible Models: TUTT S7 Pro | S3 | S6 | F3 | P7 | S7,10,11 | S9

Important: If your laptop does not have at least one full-featured USB-C port with video output support, such as Thunderbolt or DisplayPort Alt Mode, the H5 converter cable and the required display driver may be needed. For many MacBook setups, especially when connecting more than one external display, the H5 converter cable is required for the additional screen.

Connection Options Based on Laptop Ports

Review the connection method that matches your laptop. For the most stable performance, especially with dual-screen setups, TUTT recommends using external power for any screen connected by HDMI or the H5 converter cable.

Recommended Setup

1. HDMI + Full-Featured USB-C / Thunderbolt

Use this setup when your laptop has one HDMI port and one full-featured USB-C or Thunderbolt port that supports video output.

First screen: Connect a full-featured USB-C cable directly from the laptop to the USB-C port on the first screen.
No external power is usually required for the first screen when using a proper full-featured USB-C connection.
Second screen: Connect HDMI from the laptop to the HDMI/DP port on the second screen, often marked in red.
Use a separate USB-C cable to supply power to the second screen.
External power is strongly recommended for stable brightness, signal, and long-session performance.

H5 Cable Setup

2. HDMI + Regular USB-C or USB-A

Use this setup when your laptop does not support video output through USB-C or Thunderbolt.

First screen: Connect HDMI from your laptop to the HDMI/DP port on the screen, typically marked in red.
Power the first screen using a USB-C cable connected to an external power source whenever possible.
Second screen: Connect the H5 converter cable to your laptop using the USB-C and/or USB-A heads as required.
Connect the USB-C end of the H5 cable to the HDMI/DP red-marked port on the second screen.
Use an additional USB-C cable to power the second screen from an external power source.
A blue screen with connection icons should appear before driver installation.
Locate and install the required “Display” driver on your laptop.
If the second screen does not activate after installation, restart your system and reconnect the cable.

MacBook Setup

3. MacBooks with One Full-Featured USB-C + One Regular USB-C

Use this setup for many MacBook M1, M2, M3, M4 series and newer models when an additional display requires driver-assisted output.

First screen: Connect a full-featured USB-C cable directly from the MacBook to the first screen.
No external power is usually required for the first screen when the USB-C port provides both video and power.
Second screen: Connect the H5 converter cable to your MacBook.
Plug the USB-C end of the H5 cable into the HDMI/DP red-marked port on the second screen.
Power the second screen using a separate USB-C cable connected to an external power source.
A blue connection screen should appear before driver installation.
Locate and install the required “Display” driver on your Mac.
Restart your Mac if the second screen does not activate immediately after installation.

Power note: Some laptops may provide enough power for short use, but external power is recommended when using HDMI or the H5 converter cable. Stable power helps reduce flickering, black screen issues, brightness drops, and intermittent connection problems.

Technical support note: Connection results may vary depending on laptop ports, operating system, driver version, power delivery, cable condition, and display settings. Full-featured USB-C, Thunderbolt, and DisplayPort Alt Mode support are hardware-dependent features and may not be available on every USB-C port.

Portable Monitor Driver Support

Driver Updates for macOS, iPadOS, and Windows Compatibility

Some TUTT portable monitors and screen extenders require driver installation depending on the model, device, operating system, and connection method. Because macOS, iPadOS, and Windows are updated regularly, we monitor system changes and update our driver files when needed to support the latest available operating system versions.

Why drivers may need updates

Operating system updates may change display, USB, security, or permission behaviour. A driver that worked before may need to be updated after a system update.

Box driver may not be the latest

A driver included in the product box may have been prepared before the most recent macOS, iPadOS, or Windows update.

Common display symptoms

If one or more screens do not display correctly after driver installation, the issue is often resolved by reinstalling the latest driver version.

Please try this first if your screen setup is not working correctly:

Uninstall the previous driver from your computer or device.
Restart your device if required by your operating system.
Download and install the latest available driver for your model from the relevant product detail page or driver section on this support page.
Reconnect the portable monitor and test the screen setup again.

Important: In many cases, uninstalling the previous driver and installing the latest driver resolves setup or display issues, especially after macOS, iPadOS, or Windows updates.

Technical Support Request Please review the driver information and instructions available on this page first. If the issue continues after reinstalling the latest driver, continue with the support steps provided below on this page.
