Overview
Bring two computers into one simple monitor setup without keeping separate keyboards, mice, and peripherals for each system. T121 lets you move between computers from the same desk while keeping your display, everyday USB devices, audio, and network connection together.
It is a practical fit for work-and-personal computer setups, compact home offices, and anyone who wants to manage two systems without constantly moving cables or duplicating desktop equipment.
Keep Two Computers at One Simple Desk
Use one monitor, keyboard, and mouse for both computers instead of maintaining two separate setups. Keep both systems ready to use while reducing unnecessary equipment around your workspace.
Enjoy Clear 4K Display Quality
Work with sharp text, detailed images, and smooth everyday visuals at up to 4K@60Hz. T121 also supports higher refresh rates at 1080p for compatible displays and source devices.
Keep Your Display More Consistent When Switching
EDID Emulation helps your computer and monitor maintain more consistent display communication when moving between systems, reducing unnecessary display re-detection and helping your setup return more smoothly after switching.
Share the Devices You Use Every Day
Keep USB peripherals, audio devices, and a wired network connection available from the same KVM setup instead of unplugging and reconnecting accessories every time you change computers.
Get More Reliable Keyboard & Mouse Control
Choose between Pass-Through Mode and Traditional Emulation Mode depending on your keyboard and mouse. This gives you more flexibility when using multifunction devices or when extra compatibility is needed.
Switch Computers the Way That Feels Natural
Change computers from the front panel, use keyboard hotkeys, or switch with the mouse wheel. Auto Scan is also available when you want the KVM to cycle through connected computers automatically.
