The Logitech Wireless Touch Keyboard K400 Plus lets you experience PC-to-TV entertainment the way you Watch video, browse the web, chat with friends and much more. The all-in-one keyboard with touchpad ends the hassle—and clutter—of multiple devices. And a 32.8-foot wireless range ensures your fun won’t be interrupted. Comfortable, quiet keys and a large (3.5-inch) touchpad make navigating entertainment effortless. Even setup is a snap thanks to the tiny, plug-and-play Unifying receiver.

I tried two Samsung wireless keyboards for use on my Samsung J5500 smart TV, but neither one worked. I contacted Samsung and found they don't currently have one for my model. I was told my smart TV has been designed to work with "HID compliant devices", which I found the Logitech K-400 keyboard does. I plugged the dongle that came with the keyboard into the USB on the back of the TV, turned the keyboard on and was connected to my TV immediately. As I sit comfortably on my couch, everything works as easily as using my PC.....searching the web, checking emails, etc. The built-in touchpad works great too. This keyboard has a 33 foot range.....it's absolutely PERFECT!!
