Overview
Bring your USB-C laptop and desktop together in one complete dual-monitor workspace. T722 lets both computers share the same displays, keyboard, mouse, USB devices, audio, and network connection, so you can move between laptop and desktop workflows without constantly reconnecting your setup.
Whether you work from a laptop during the day and switch to a desktop for more demanding tasks later, T722 keeps both systems ready at the same desk while giving you more flexibility across two monitors.
Bring Your Laptop and Desktop Together
Keep your USB-C laptop and HDMI/DisplayPort desktop connected to the same workstation. Instead of maintaining separate monitors, keyboards, mice, and accessories for each computer, both systems stay ready to use from one shared setup.
Get a True Extended Desktop on Your Mac
Use a compatible Mac with two USB-C connections to extend your desktop across two monitors, giving each screen its own workspace instead of simply mirroring the same image. One cable connects to the MST + USB port and the second connects to the DP Alt Mode port. Compatible Windows systems can use MST to achieve extended dual displays through a single USB-C connection.
Work Across Two Screens Your Way
Use both monitors with one computer when you need more screen space, or display your laptop on one monitor and your desktop on the other. Independent display switching makes it easier to compare information, monitor another system, or work across two computers at the same time.
Keep Your Desktop Layout More Consistent
Switch between computers without constantly rebuilding your screen layout. Ghost Display (EDID Emulation) helps reduce monitor re-detection and unexpected window rearrangement, so your workspace stays more consistent when moving between systems.
Keep Your USB-C Laptop Powered While You Work
Power your compatible USB-C laptop through the same workstation instead of adding another charger to your desk. With up to 100W Power Delivery on PC 1, T722 helps keep your laptop charged while it stays connected to your monitors and shared devices.
Share More Without Reconnecting Everything
Keep USB peripherals, audio devices, and Gigabit Ethernet available from the same desk. Move between computers without repeatedly unplugging storage devices, webcams, headsets, or network cables, making a mixed laptop-and-desktop setup much easier to manage.

Will T722 work with my laptop and desktop setup?
Yes. T722 is designed for hybrid workstations with one USB-C laptop and one HDMI/DisplayPort computer.
PC 1 connects through USB-C, supporting video, USB data, and power delivery.
PC 2 connects through HDMI, DisplayPort, and USB-B for video and USB control.
You can share two HDMI monitors, one keyboard and mouse, USB peripherals, audio devices, and a Gigabit Ethernet connection between both computers.
Can I connect my USB-C laptop with only one cable?
For compatible Windows laptops, yes.
When using MST mode, connect your laptop to the T722 USB-C port labeled "MST + USB" with one USB-C cable. This single connection supports video output and USB data.
For macOS devices, dual-monitor operation requires SST mode with two USB-C connections.
Can I display two different computers on two monitors at the same time?
Yes. T722 supports mixed display mode, allowing each monitor to show content from a different computer simultaneously.
For example:
- Monitor A → Work laptop
- Monitor B → Desktop PC
You can also switch keyboard, mouse, USB, and audio focus between computers.
Does T722 support MacBook?
Yes, but with limitations.
macOS does not support MST. For Mac systems, T722 supports SST mode, which requires two USB-C connections for dual-monitor operation.
The final display capability depends on whether your Mac can provide independent display outputs.
Will switching between computers move my windows or reset my display layout?
T722 includes a Virtual Display / Ghost function designed to reduce window rearrangement and display re-detection when switching between computers.
If your desktop layout changes after switching, enable the Ghost function using the front button or keyboard shortcut.
How much charging power does T722 provide?
The PC 1 full-featured USB-C input supports up to 100W Power Delivery charging.
This allows compatible USB-C laptops to receive power while connected to T722.
Can I share my keyboard, mouse, USB devices, and Ethernet connection?
Yes. T722 allows both computers to share:
- Keyboard and mouse
- USB peripherals
- 3.5mm audio devices
- Gigabit Ethernet connection
The front USB-A ports support USB 3.2 Gen 1 data transfer up to 5Gbps.
