USB-C to 3 HDMI Adapter with 100W PD - 3-Monitor Splitter

In this review the Reborn USB-C to 3 HDMI Adapter is evaluated as a practical solution for users who need a compact way to drive multiple displays. The bottom line: it is best for Windows laptop owners and desktop users with a full-function Thunderbolt or DP Alt Mode USB-C port who want to extend or mirror to up to three monitors without installing drivers. The adapter's single biggest draw is its combination of a true 1 in 3 out MST hub and a built-in 100W Power Delivery port so a workstation can be powered while feeding multiple screens.

Key Features

• 3-Monitor Display Solution: Converts a USB-C signal into three HDMI outputs to extend or mirror displays for improved multitasking on Windows.
• Plug-and-Play: Requires no drivers when used with a full-function Thunderbolt or DP Alt Mode USB-C port, simplifying installation.
• Selective Resolution Support: One HDMI port can run at 4K@60Hz while two others run at 1080p, covering common mixed-resolution setups.
• High Power Delivery: The hub provides 100W PD (100W in, 90W out) so it can power most laptops and free up the laptop power jack.
• Windows MST and macOS Mirror: Supports extended desktop (MST) on Windows and mirror-only mode on macOS, clarifying cross-platform behavior.
• Durability and Support: Built with attention to manufacturing quality and backed by responsive after-sales service and a 24-month warranty.

Who It's For

This adapter is aimed at professionals, creators, and power users who run Windows laptops or desktops with USB 3.1 Gen2+ or Thunderbolt 3/4 ports and need a tidy multi-monitor setup without extra docks. If you want to run mixed resolutions across three displays while keeping your laptop charged, this unit handles that workflow well.

Users on macOS who expect independent extended displays should look elsewhere because macOS is limited to mirror mode with this adapter. Also avoid connecting the adapter through another hub, dock, or KVM - it needs a direct full-function USB-C port to work correctly.

Pros & Cons

Pros

• Supports three HDMI outputs from one USB-C port for efficient multi-monitor setups.
• 100W PD passthrough powers most laptops while driving displays, reducing cable clutter.
• Works plug-and-play on supported ports with no driver installation required.
• Clear platform behavior: MST extend on Windows and mirror on macOS prevents confusing expectations.

Cons

• All three ports only reach 4K@60Hz with higher-end GPUs (NVIDIA RTX 2060 or AMD RX 6600 XT or better), so mixed resolution setups are common.
• Not compatible when connected through other hubs, docks, or KVM devices, requiring a direct USB-C port.

Our Verdict

The Reborn USB-C to 3 HDMI Adapter is a sensible, good-value choice for Windows users and owners of modern laptops with Thunderbolt or DP Alt Mode who need to run multiple monitors while keeping a single power connection. It simplifies multi-monitor setups and reduces desk clutter, though macOS users and anyone needing guaranteed independent 4K@60Hz on all three outputs should verify system compatibility first.

Frequently Asked Questions

Can I run three independent displays at 4K@60Hz?
All three outputs only reach 4K@60Hz on systems with powerful GPUs such as an NVIDIA RTX 2060 or AMD RX 6600 XT or better; otherwise one port is 4K@60Hz and the others default to 1080p.

Does this need drivers to work?
No drivers are required when the adapter is connected to a full-function Thunderbolt or DP Alt Mode USB-C port; it is plug-and-play on supported systems.

Will it work through my USB hub or dock?
No; the adapter should be connected to a direct USB-C port on the host device and not through another hub, dock, or KVM to ensure compatibility.
