Description

Plugable USB-C Dual 4K HDMI MST Display Adapter

The Plugable USB-C to Dual HDMI MST Display Adapter lets you connect two independent 4K displays to your Windows or Chromebook laptop through a single USB-C port. Using Multi-Stream Transport (MST) technology, it delivers a true extended desktop experience without the need for DisplayLink drivers or external power bricks.

Dual 4K@60Hz with DSC

When paired with a host that supports DisplayPort 1.4 and Display Stream Compression (DSC), you can run both displays at 4K@60Hz. For older hosts, it supports dual 4K@30Hz or dual 1080p@60Hz. This makes it perfect for multitasking across spreadsheets, code, and design apps.

Plug-and-Play Setup

Simply plug the adapter into a USB-C port with DisplayPort Alt Mode, connect your HDMI monitors, and you're ready. No software installation required on Windows (10/11) and Chromebooks (v100+). Note: MacOS does not support MST, so this adapter may mirror the display instead of extending.

Compact, Portable Design

The lightweight adapter is ideal for mobile professionals who need a multi-monitor setup on the go. It works with USB-C and Thunderbolt 3/4 ports, making it a versatile addition to your travel kit.

Product Details

Leave the bulky docking station behind and travel light.

Frequently Asked Questions

Why does my Mac only mirror the display?

macOS does not support MST for extending displays. This adapter mirrors your Mac's screen on both connected monitors. For extended desktop on Mac, consider a DisplayLink-based adapter.

Does this adapter require drivers?

No. It uses native MST support in Windows 10/11 and Chromebooks. Just plug and play – no DisplayLink drivers or installation needed.

What host requirements are needed for dual 4K@60Hz?

Your laptop must have a USB-C port with DisplayPort 1.4 and support Display Stream Compression (DSC). Many recent Intel and AMD laptops meet this. If not, you'll get dual 4K@30Hz or lower.

Can I use this adapter with a Thunderbolt 3 port?

Yes, Thunderbolt 3/4 ports support DisplayPort Alternate Mode, so the adapter will work with them.

Works well, but a bit pricey

The adapter does exactly what it says. I can run two 4K monitors at 60Hz. The build is solid. The only reason I'm not giving five stars is the price, which is a bit high compared to similar adapters.

Perfect for my M1 Mac

I was worried about compatibility with my M1 MacBook, but this works flawlessly. I can run two external monitors in extended mode. The MST function is a game changer. Super easy setup.

Inconsistent on Mac

It worked on my Windows laptop without issues, but on my MacBook (Intel), it only duplicated the display instead of extending. I followed the instructions and updated macOS, but still no luck. It's a shame because the hardware seems fine.
