USB C Splitter Dual 4K/60Hz Hub - Dual Monitor USB C Docking

Our review of this USB C Splitter finds it best suited for users who need to extend a single USB C port into multiple high-bandwidth USB C connections, especially dual 4K USB C monitors when the laptop supports USB 4 or Thunderbolt 4. The bottom line: it is a compact, well-built USB C hub that stands out for its Intel JHL8140-based dual 4K/60Hz video output and roomy power delivery, but buyers should check platform compatibility carefully before purchasing to ensure full dual-display support.

Key Features

• Dual 4K Video Output: Extends one USB C port to two USB C monitors with up to 4K/60Hz output when the host and monitors meet the required USB 4 or Thunderbolt 4 and DP Alt Mode support.
• Intel JHL8140 Chip: Uses a dedicated controller to manage dual display streams and improve compatibility with high-resolution monitors.
• 5-in-1 Connectivity: Provides two 10 Gbps USB C data ports, two USB C video ports, and one USB C PD port so users can connect displays and fast USB C peripherals simultaneously.
• 100W PD Charging: Supports up to 87W pass-through charging to keep a laptop powered while using multiple devices and maintaining stable data transfer.
• MST and SST Support: Supports MST and SST for dual-display on many Windows laptops with DP Alt Mode, enabling extended desktop setups with compatible monitors.

Who It's For

It is ideal for professionals and students who use modern Windows laptops or Thunderbolt 4/USB 4 systems and need a portable docking solution to connect dual USB C monitors at native 4K/60Hz. Remote workers running virtual classrooms or multitasking workflows will value the compactness and the mix of video, data and power delivery in a single adapter.

Users of older USB C laptops, Macs with limited MST or non-DP Alt Mode ports, or anyone relying on native multi-monitor support on classic Mac OS setups should look elsewhere or confirm their machine supports DP Alt Mode and the required Thunderbolt 4/USB 4 behavior before buying.

Pros & Cons

Pros

• Compact and well built, making it easy to carry between workstations.
• Delivers high-bandwidth video for dual 4K/60Hz monitors on compatible hosts.
• Fast 10 Gbps USB C data ports extend peripheral connectivity and speed.
• Pass-through charging up to 87W keeps a laptop powered during heavy use.

Cons

• Dual 4K/60Hz output requires USB 4 or Thunderbolt 4 hosts and DP Alt Mode monitors, limiting compatibility with some laptops and Mac OS setups.
• Some users report mixed results with Mac devices and power delivery behavior, so testing is recommended.

Our Verdict

This USB C Splitter is a practical, value-oriented docking option for users with modern USB 4 or Thunderbolt 4 laptops who need to drive dual USB C monitors and maintain fast data and charging.

Frequently Asked Questions

Will this hub drive two 4K/60Hz monitors?
Yes, when the host laptop is USB 4 or Thunderbolt 4 and the monitors support USB C DP Alt Mode, the hub can output dual 4K/60Hz.

Does it charge my laptop while in use?
Yes, it supports pass-through PD charging up to 87W but requires a separate charger connected to deliver power.

Will it work with my Mac?
Mac OS has limitations with MST and some M1/M2 models may only support a single external 4K/60Hz display; check your Mac model and DP Alt Mode support before purchase.
