Q: QuestionI just bought a wireless Logitech K400 Plus and I Do Not Understand HOW to hook this up ..... Can anyone HELP Me ? I have a Samsung Smart TV ....

Asked 8 years ago by Clueless.

• A:Answer I got a newer Samsung SmartTV so I will only speak to my personal experience. The keyboard came with a small USB fob - its about the size of a thumbnail. That needs to go into one of your TV's USB ports on the back. If your Samsung Smart TV does not have a USB port, then return this one and see if your TV support's Bluetooth instead. But assuming your TV does have a USB port, plug in the fob. Turn on the TV. Now you have that part working. Next is to make sure your keyboard has the batteries installed and that the little plastic pull tabs (that cover the battery connections) are removed so as to make sure the keyboard has power. Lastly turn on the keyboard (there is a switch on the back). Now to use the keyboard with the TV, the right side is like the touchpad on a laptop. I like to click the Smart TV on my remote to pull up the apps, and then start using the keyboard mouse to select the apps. Now a very important note - not every App works with the keyboard - they were written to use the TV remote only. So YouTube for example is one app that does not use the keyboard, but the browser does. Hopefully this helps some.

Q: QuestionDoes the K400 work with an iPad? What is the purpose of the touchpad?

Asked 8 years ago by Anonymous.

• A:Answer It does indeed work with an iPad if you have a USB adapter. I’m not sure what it’s called but I have one of these - it’s an adapter that attaches to the iPad (I have both an iPad 2 and a much newer Pro. I bought the USB adapter when I bought each iPad, to match their jack. One of the adapters available offers an SD card slot, and the other common one is a USB port. I’m typing this on an iPad Pro, using the USB adapter, and a K400+ Logitech keyboard. The RF receiver plugs into the USB adapter, which in my case plugs into the lightning jack where the power cord would normally attach. The trackpad portion of the keyboard has no purpose; you still need to touch the screen to click where needed. Amazingly the on-screen keyboard does not appear when the K400+ is attached. This is very handy for writing longer pieces, I imagine. I never tried this arrangement until I found your question. I guess this means my gaming keyboard would also work!

Q: QuestionIs this keyboard compatible with MacBook Pro M1 and Big Sur?

Asked 4 years ago by bluffid.

• A:Answer Hello bluffid! The K400 Plus Wireless Keyboard should work with your MacBook Pro M1 and Big Sur yes, using its USB Unifying Receiver (no Bluetooth), but you'd have to use a USB Hub on your Mac to convert the Thunderbolt ports to USB. Also, do note that the K400 Plus is not officially supported for MacOS, meaning you won't be able to customize your keyboard buttons through Logitech Options, nor use gestures on the trackpad and such, so it would just work as a regular keyboard with trackpad.

Q: Questionone more thing.i prefer desktop mouse too. can i still use my wireless mouse with this?

Asked 9 years ago by bellsmom.

• A:Answer Yes. But if you're looking for just a good wireless keyboard, there are far better options that don't have a track-pad. Typing on this keyboard is not the greatest. I'd suggest looking elsewhere.

Q: QuestionDoes this work with a Windows 10 PC?There are no lights on the keyboard to indicate if it is even on, no light to tell if it is connecting, I have no idea if this is Bluetooth or not since I'm not sure what the Unifying device is, but I would assume it is Bluetooth? Does this only work on Windows 10 All-in-one systems or something? I swapped out the batteries and it still doesn't work. I was under the impression this works on any Windows 10 device as the box says, not sure what a TV-connected PC is, I have a PC with Windows 10 installed that uses a TV as a monitor, is that the same as the TV-connected PC the description is referring to?

Asked 9 years ago by Anonymous.

• A:Answer Yes it does work with Windows 10, and no it is not bluetooth. It uses it's own tiny wireless USB receiver. When I opened the box, that USB receiver was just floating around inside and if I didn't know to look for it I would have thrown it out with the box. The keyboard won't work without it. Did you plug in the USB receiver?

Asked 8 years ago by taxman.

• A:Answer It works with my LG 4K TV. While I don't have the exact TV you do, I imagine if it supports one LG TV it probably supports their entire current line.

Q: QuestionIs this product only meant to use to hook up to a television for use? I just wanted to use it at my desktop. Thank you for your answer.

Asked 8 years ago by Lacey.

• A:Answer No, you plug the USB dongle into your computer so it's actually controlling your computer some people like myself use the tv as a second monitor. You can control other devices if you choose too but It will work perfectly for your purpose and save your PC keyboard from wear and tear or a cheap replacement for a Broken pc keyboard I love mine and if your used to a laptop touchpad your transition will be seamless. If your used to using a mouse I think you'll enjoy the 1 less piece of equipment once you get used to the built in touch pad. I highly recommend the Logitech 400 plus. Hope this answers your question

Q: Questiondoes work windows 7 64 bit home premium desktop computer?I know nothing about technical stuff of computers. use a home desktop windows 7 home premium got new in 2009 mostly for necessity as banking, paying bills, etc. I'm now legally blind not drive anymore or have internet phone, etc. i often have to bring the keyboard closer to me to see it but the cord makes it very hard to do. i want a cordless/wireless one for this issue alone. will this work for this purpose? thx. much .

Asked 9 years ago by bellsmom.

• A:Answer The keyboard works on any current Windows version. If you are having a difficult time seeing, this may not be the best choice in keyboards. The keys are smaller and it is a grey on grey contrast for the letters (not back lit). This keyboard from Walmart is what my old department chair used for his severe retinal degeneration. http://goo.gl/BTwhRF Best Buy sells a multi color back lit version which I like better for $5 more. Same large letter features, but with back lighting on the keys. http://goo.gl/S7AFHw Hope this helps.
