Frequently Asked Questions - U4443HMST Tripp Lite

Which types of devices are compatible with the U4443HMST?

The adapter is compatible with any device equipped with a USB Type-C or Thunderbolt 3 port supporting DisplayPort Alt Mode 1.4, including laptops, tablets, MacBooks, and Chromebooks.

Can I use this adapter with a Mac to display three screens in extended mode?

Yes, on macOS, the adapter operates in SST (Single-Stream Transport) mode, which allows displaying the same content on all three screens, or extending the desktop if the operating system allows it. For three screens in extended mode, a Windows system is recommended with MST mode.

What maximum resolution can I achieve with three monitors connected?

On Windows: 1 display at 4K @ 60 Hz + 2 displays at 4K @ 30 Hz. On macOS: all three displays can achieve 4K @ 60 Hz simultaneously, but in mirror mode (SST). Performance depends on host support for DP 1.4.

Does the adapter require an external power supply?

No, the adapter is powered directly from the USB bus of the host device. Its standby power consumption is less than 1 W.

What should I do if only one display works when I have connected two?

First, check that your host device supports MST mode (Windows) or SST (macOS). Also ensure that the HDMI cables are securely connected and the monitors are powered on. Restart the computer if necessary.

Does the adapter support HDR?

Yes, the adapter supports HDR (High Dynamic Range) for better contrast and color accuracy.

Is this adapter compatible with HDCP displays?

Yes, it is compatible with HDCP 1.4 and HDCP 2.2 standards, allowing playback of protected content like 4K streaming videos.

Can I use the adapter with a USB-C port that does not support DisplayPort Alt Mode?

No, the adapter requires the host USB-C port to support DisplayPort Alt Mode (DP Alt Mode). Without it, no video signal will be transmitted.

How do I clean the adapter?

Disconnect the adapter before cleaning. Use a soft, dry cloth to remove dust. Do not use liquids, sprays, or abrasive products.

What does the warranty for this adapter cover?

Tripp Lite offers a 3-year limited warranty against defects in materials and workmanship. It does not cover normal wear, misuse, or accidental damage.

Product Features

When Used with Windows® Host Device

• Allows connection of 2 displays (max 4K @ 60 Hz) showing different images under Multi-Stream Transport (MST) mode

When Used with macOS® Host Device

- Allows connection of 3 displays (max 4K @ 60 Hz) showing the same images under Single-Stream Transport (SST) mode

Notes:

• To achieve the above resolution, the host should support DP 1.4 Alt Mode. If connected to a DP 1.2 Alt Mode host, the corresponding resolution will be decreased due to bandwidth limitation.
• The above resolution combination is for theoretical reference. The actual output resolution depends on the connected host and displays.
• When working with a 2080 graphics card, this product does not support 10-bit Deep Color.
