USB C to HDMI Splitter Dual Monitor Adapter - 4K/1080p

In this review of the avedio links USB C/USB 3.0 to HDMI Splitter Extended Display, the bottom line is simple: this adapter is for laptop users who need an inexpensive, plug-in way to add one or two external displays and a USB 3.0 port without swapping docks. It excels when used with Windows or Mac laptops that support DisplayLink drivers and offers a clear advantage for multitaskers who want a larger workspace, with one HDMI output capable of 4K@30Hz and a second HDMI at 1080p@60Hz.

Key Features

• Dual HDMI outputs: Two HDMI ports let users connect two monitors to duplicate or extend the laptop screen for better multitasking.
• USB Hub 2 in 1: Includes both a USB A 3.0 and a USB C 3.0 host plug so you can choose the port that fits your laptop.
• DisplayLink support: Works with DisplayLink drivers to expand multiple monitors on Windows (up to eight) and Mac OS (up to six) for large display arrays.
• Resolution split: HDMI out 1 supports up to 4K@30Hz while HDMI out 2 supports up to 1080p@60Hz to balance a high-res primary screen with a secondary full HD display.
• Extended and mirror modes: Supports ABB and ABC extended configurations as well as mirror mode to suit different workflow demands.
• Simple setup: Requires an initial driver install and, on Mac, a permissions setting like screen recording; after that it is plug-and-play for most uses.

Who It's For

This adapter suits professionals and students who use Windows 7/10/11 or Mac OS 10.13 and later and need a compact way to add two displays without a full docking station. It is especially useful for people who value a mixed-resolution setup: a crisp 4K primary monitor and a secondary 1080p screen for documents or chat windows.

It is not intended for users of Android, Chrome OS, Linux, Unix or other unsupported systems, nor for those who need identical high-resolution output on both screens since the two HDMI ports deliver different maximum resolutions.

Pros & Cons

Pros

• Adds two HDMI displays from one USB C or USB A port for increased desktop space.
• Includes a USB 3.0 port for peripherals while still providing display outputs.
• Supports DisplayLink to scale up to multiple monitors on Windows and Mac.
• One HDMI port reaches 4K@30Hz, making it suitable as a primary high-res display.

Cons

• Second HDMI is limited to 1080p@60Hz, so both displays cannot run at the same 4K resolution.
• Requires an initial driver install and Mac permission settings, adding a short setup step.
