OUR VERDICT

Is it right for you?

K400 Plus is a specialized choice for controlling a living-room computer from one device. The touchpad removes the need for a separate mouse surface. It is less compelling as a main keyboard for lengthy typing sessions, and a TV with USB ports is not automatically a compatible computer.

Before you buy

Start with the device behind the TV

K400 Plus is intended for a TV-connected PC. Check the computer or media device you actually use, rather than assuming the TV itself supports every keyboard function. USB keyboard support, pointer behavior, and media shortcuts can differ between operating systems and individual apps.

Convenient control has compromises

An integrated touchpad can be useful when there is no desk beside you. It is a different interaction from a full-size mouse, particularly for precise selection or long editing tasks. Confirm the language and layout on the linked Amazon listing before ordering.
