The Logitech K400 Plus Wireless Touch TV Keyboard is a purpose-built input device designed for navigating media and web content on a PC-connected television. It integrates a full QWERTY keyboard with a built-in touchpad, eliminating the need for a separate mouse and enabling comfortable control from the sofa. The keyboard features dedicated media control keys, allowing users to adjust volume, play, pause, skip tracks, and access other multimedia functions without interrupting their viewing experience. Constructed with a robust plastic chassis, the unit is built to withstand daily handling while maintaining a lightweight profile for easy portability. The scissor-key mechanism provides a crisp, responsive typing feel with adequate key travel, suitable for occasional text entry such as searching streaming services or typing URLs. The touchpad supports multi-touch gestures, including two-finger scrolling and tap-to-click, offering a familiar laptop-like navigation experience. Wireless connectivity is achieved via a Logitech Unifying USB receiver, delivering a reliable signal range of up to 10 meters, ensuring stable operation even when the keyboard is used across a room. Power efficiency is a key attribute, with two AA batteries providing up to 18 months of typical usage, reducing the frequency of replacements. The keyboard is compatible with Windows, Android, ChromeOS, and select smart TV platforms, making it a versatile accessory for home entertainment setups. Its compact layout omits a number pad to conserve space, yet retains essential keys like Escape and function row shortcuts for quick access to brightness, display settings, and system controls. The black color finish is matte, minimizing fingerprints and glare under ambient lighting. For users seeking a straightforward, reliable way to control a TV-connected computer or media center, this model offers a balanced combination of utility, durability, and straightforward operation. The build quality reflects Logitech’s attention to consistency, with well-seated keycaps and a solid hinge mechanism for the stand that props the receiver in an optimal position.

The K400 Plus serves as an effective solution for home theater PC (HTPC) interaction, emphasizing ease of use and dependable performance without unnecessary complexity.
