Lemorele USB-C to USB-C Video Splitter — Dual 4K@60Hz

The Lemorele USB-C to USB-C Video Splitter converts a single Thunderbolt 4/USB4 port into two USB-C video outputs, delivering dual 4K@60Hz displays (when DP Alt Mode and MST are supported) while passing up to 100W power.

Built for modern Windows laptops and other Type-C devices that support DisplayPort Alternate Mode, this compact video hub expands one high-bandwidth USB-C port into a three-port solution: two USB-C video outputs plus a PD charging inlet. It uses an upgraded video chip to manage MST and SST modes on compatible Windows machines, supports DP Alt Mode 1.4 for crisp 4K@60Hz monitors, and supplies up to 87W pass-through charging for most notebooks. Note that macOS does not support MST-based dual displays; always confirm your portable monitor or device explicitly supports DP Alt Mode before connecting.

How does this splitter create a dual-monitor workstation?

The hub leverages DisplayPort Alternate Mode 1.4 and MST (Multi-Stream Transport) to send two independent video streams from a single Thunderbolt 4/USB4 port to two USB-C monitors. When your laptop and monitors both support DP Alt Mode and MST, you can run two extended displays at high resolutions.

• Dual USB-C video outputs compatible with DP Alt Mode 1.4
• Supports MST for independent extended displays on Windows Thunderbolt 4/USB4 systems
• Delivers up to 4K@60Hz per monitor when bandwidth allows
• macOS does not support MST dual-monitor expansion via this hub

Will my laptop stay powered while using two external displays?

Yes — the Lemorele splitter includes a dedicated USB-C PD input that supports pass-through charging up to 100W, with about 87W available to power most laptops while driving video and data. You’ll still need to supply your own USB-C PD charger and cable.

• 100W PD-compatible input for high-wattage charging
• Approximately 87W laptop pass-through under normal conditions
• Maintains stable power while transferring video and data
• Charger and PD cable are not included with the hub

Which devices are compatible, and where are there limitations?

This hub is designed for Thunderbolt 4 and USB4 Windows laptops and other Type-C devices that implement DisplayPort Alternate Mode. It’s also suitable for portable USB-C monitors, AR glasses, Steam Deck, and many Android devices — provided the device supports DP Alt Mode for video. macOS laptops cannot use MST for true dual independent displays through this splitter.

• Optimized for Thunderbolt 4 / USB4 Windows laptops
• Compatible with USB-C portable monitors and AR glasses that support DP Alt Mode
• Works with Steam Deck and some Android Type-C devices if DP Alt Mode is present
• MST dual-monitor functionality is not available on macOS

How do I verify my monitor or laptop supports the required video protocols?

Check the product specifications or look for the DP Alt Mode symbol on the monitor or device’s USB-C port. Manufacturer pages for laptops and portable monitors usually list DisplayPort Alternate Mode or Thunderbolt/USB4 support clearly. If uncertain, consult the device manual or vendor before purchasing.

• Look for a DP Alt Mode icon or “DisplayPort over USB-C” in specs
• Confirm Thunderbolt 4 / USB4 support on the host laptop for best results
• Review monitor specs to ensure DP Alt Mode is supported
• Contact support when in doubt to avoid incompatibility

Who this is for: The Lemorele USB-C to USB-C Video Splitter is aimed at users who need a compact, high-resolution dual-monitor setup from a single Thunderbolt 4/USB4 port — especially Windows professionals, content creators, and gamers using portable USB-C monitors or devices like the Steam Deck. It’s also a good choice for travelers and hybrid workers who want a small, powerful hub for multi-screen productivity, provided their laptop and monitors support DP Alt Mode and MST where required.
