UANTIN USB-C to 3 HDMI Adapter with 100W PD

The UANTIN USB-C to 3 HDMI adapter lets a single USB-C/Thunderbolt laptop output to three independent HDMI displays at up to 4K@60Hz on Windows while delivering up to 100W power delivery.

Designed for professionals who need multiple screens, this compact aluminum adapter expands one USB-C port into three HDMI outputs and a PD charging port. It uses MST technology to create three separate displays under Windows (macOS supports mirror-only or single output), supports HDR and 4K@60Hz on compatible panels, and includes a 100W PD pass-through so you don't lose charging while driving multiple monitors.

How many monitors can I run and with what resolution?

You can connect up to three independent HDMI monitors from a single USB-C source on Windows using MST (Multi-Stream Transport). Each monitor can show up to 4K@60Hz if your laptop and displays support HDMI 2.0 and the host's DP Alt Mode bandwidth is sufficient.

• Triple independent displays on Windows via MST.
• Supports up to 4K @ 60Hz per monitor on compatible hardware.
• HDR support for richer color and contrast where available.
• macOS limited to mirrored outputs or single monitor output.

Will the adapter keep my laptop charged while using multiple screens?

Yes — the adapter includes a PD 3.0 power input that supports up to 100W pass-through charging. Plug your laptop charger into the adapter’s PD port to power high-wattage notebooks while the three HDMI outputs are in use.

• 100W PD pass-through maintains laptop battery and performance.
• Compatible with most USB-C chargers that support PD protocol.
• Avoids occupying the laptop’s USB-C ports for charging separately.

Is this adapter plug-and-play and compatible with my device?

The UANTIN adapter is plug-and-play and does not require drivers; however, device compatibility depends on the host supporting DisplayPort Alt Mode and, for separate displays, MST (Windows). Check your laptop’s specifications to confirm DP Alt Mode and available bandwidth for triple 4K outputs.

• Plug-and-play on supported systems, no drivers needed.
• Requires DP Alt Mode from the USB-C port; MST needed for Windows triple displays.
• macOS will mirror or output to a single display only.

How durable is the adapter and how does it handle heat or interference?

The adapter is built with an all-aluminum shell and a braided cable to improve heat dissipation and resist wear. Gold-plated connectors and shielding reduce signal interference for stable video transmission across long sessions.

• Aluminum housing for better heat conduction and longevity.
• High-density braided cable prevents tangling and reduces strain.
• Gold-plated connectors and shielding for stable, interference-resistant signals.

Who this product is for: The UANTIN USB-C to 3 HDMI adapter is best for knowledge workers, designers, traders, coders, and anyone who needs multiple screens to multitask on Windows laptops that support DP Alt Mode and MST. It's ideal when you want full charging capability alongside three external monitors, and for users who value a sturdy, plug-and-play solution. If you use macOS primarily, expect mirrored displays unless you rely on single-monitor output; verify your host’s DP Alt Mode and HDMI version to achieve the highest resolutions.
