Overview
Bring two USB-C laptops into one complete dual-monitor workspace without rebuilding your desk every time you switch computers. T422 keeps your monitors, keyboard, mouse, USB devices, audio, network connection, and laptop charging together in one setup, so moving between work systems feels much more seamless.
For Mac users, T422 also solves an important dual-monitor limitation: on compatible Macs with two independent video outputs, two USB-C connections allow you to create an extended dual-monitor desktop, instead of simply showing the same image on both screens.
Turn Two Laptops into One Complete Workspace
Keep two USB-C laptops ready at the same desk without maintaining separate monitors, keyboards, mice, and peripheral setups. Move from one system to the other while keeping the rest of your workspace in place.
Get a Real Extended Desktop on macOS
Use two USB-C connections with a compatible Mac to extend your desktop across two monitors, giving each screen its own workspace instead of simply duplicating the same image. Windows systems that support MST can achieve dual-display output through a single compatible USB-C connection.
Work Across Two Screens Your Way
Use both monitors for one computer when you need more room, or place different computers on each display when comparing files, monitoring systems, or working across two platforms. Each screen can be controlled independently.
Keep Your Windows Where You Left Them
Switch between laptops without constantly rebuilding your desktop layout. Ghost Display (EDID Emulation) helps reduce monitor re-detection and unwanted window rearrangement when changing systems.
Keep Both Laptops Powered While You Work
Connect compatible USB-C laptops without giving up charging. Each laptop can receive up to 65W Power Delivery through its dedicated MST + USB PD connection, helping reduce the need for additional power adapters on the desk.
Share More Without Reconnecting Everything
Keep fast USB peripherals, audio devices, and Gigabit Ethernet available from the same workstation. Instead of moving accessories between laptops, switch the system you want to use and keep your essential devices within reach.

Will T422 work with my laptop and desktop setup?
Yes. T422 is designed for two-computer dual-monitor setups. Each computer connects through a full-featured USB-C input that supports MST video output, USB data, and USB Power Delivery, allowing you to share two HDMI monitors, keyboard, mouse, USB devices, audio, and a Gigabit Ethernet connection between two computers.
Can I connect my laptop with only one USB-C cable?
Yes, when your laptop's USB-C port supports video output (DP Alt Mode/MST) and USB data, a single USB-C connection can carry display signals, USB data, and charging through T422. The USB-C input supports up to 65W Power Delivery charging.
Does T422 support dual monitors from one USB-C laptop?
Yes. T422 supports MST technology, allowing a compatible USB-C source to output to two displays through a single USB-C connection.
Note: macOS does not support MST. Dual-display operation on Mac depends on whether the Mac can provide independent display outputs.
Can I use two computers on two monitors at the same time?
Yes. T422 supports independent display switching and mixed-screen mode, allowing each monitor to display content from a different computer at the same time.
Example:
- Monitor A → Work laptop
- Monitor B → Personal PC
Will switching computers rearrange my windows or reset my display settings?
T422 includes a Ghost virtual display feature designed to reduce window rearrangement, resolution changes, and display re-detection when switching between computers.
If your windows move after switching, enable Ghost mode using the front Ghost button or the hotkey shortcut.
Can I share my keyboard, mouse, USB devices, and Ethernet connection?
Yes. T422 allows two computers to share:
- Keyboard and mouse
- USB 3.2 Gen Ports
- 3.5mm audio/microphone devices
- Gigabit Ethernet connection
The front USB ports support up to 5Gbps data transfer and 7.5W output power.
Does T422 support MacBook?
T422 can work with Mac computers, but dual-monitor behavior depends on the Mac model and its display output capability.
macOS does not support MST, so Mac users should confirm whether their device can provide independent display outputs for dual-monitor operation.
