Logitech K400 Plus — The Ultimate Wireless Living Room Keyboard
The Logitech K400 Plus is a specialized wireless touch keyboard designed for total control of your PC-to-TV entertainment system. By integrating a precise 3.5-inch touchpad directly into the keyboard layout, it eliminates the need for a separate mouse, making it the perfect companion for browsing the web or navigating streaming services from the comfort of your sofa.
Compact design with integrated touchpad for effortless navigation.
To unlock advanced features like multi-touch gestures and custom function keys, installing Logi Options+ is essential. This software allows you to adjust pointer speed, customize the “Left-click” button at the top-left of the keyboard, and remap F-keys to open your favorite media apps with a single press.

? FAQ
Why is the touchpad not working on my K400 Plus?
First, check if the batteries are properly installed. If the keyboard type works but the touchpad doesn’t, ensure you have installed Logi Options+. Sometimes, Windows generic drivers fail to recognize multi-touch gestures. Also, try plugging the Unifying receiver into a different USB port, preferably one not blocked by the TV’s metal chassis.
How can I disable the “Tap to Click” feature?
By default, “Tap to Click” is enabled. To change this, open the Logi Options+ software, select your K400 Plus, go to the “Point & Scroll” section, and toggle the “Tap to Click” switch. You can also adjust scroll speed and direction there.
Can I use the K400 Plus with a Smart TV or PlayStation?
The K400 Plus is compatible with many USB-enabled Smart TVs (especially Android TV and Tizen) and game consoles like PS5/Xbox for typing. However, the touchpad and special hotkeys are not guaranteed to work on all TV models as it depends on the TV’s internal driver support.
