A:AnswerHello, the K400 Plus is a PC-to-TV keyboard, so you will need to connect it to a computer. It does not work with just a smart TV. You can look at the K600 if you want a keyboard that will connect to your Vizio. https://www.bestbuy.com/site/logitech-k600-tv-wireless-keyboard-dark-gray/6282604.p?skuId=6282604
A:AnswerUnfortunately, the K400 plus doesn't work with iOS, as it requires a USB receiver. You would want a pure Bluetooth keyboard, that doesn't require a USB receiver to work, like the K380 or the K480 keyboards.
A:AnswerYes... as long as you have the USB plug for the mouse. If you have a compatible Logitech mouse, you can download the software and configure the Unifying USB plug to work with both, meaning you'll only need one USB plug for mouse and keyboard.
A:AnswerHello. The K400 does support gesture controls. You can define them using our Logitech Options software that you can download for free on our website.
A:AnswerThe Logitech K400 keyboard will work with your HP laptop. You will just need to plug the receiver into a USB slot. I also recommend using the Logitech software for best experience. I have attached a link to the “getting started” guides for your reference. There is a downloads tab with relevant software downloads.
Best regards,
