A:AnswerMost things on the tv should already be pre set to 4K. If you want to be sure everything is 4K, there's a specific channel you can add that's the "4K channel" it shows quick videos in 4K, it looks amazing! Try that.
A:AnswerYes, it not only has screen mirroring, it has this as well: Anyview Stream: Share video, music or other content files from another device to your TV screen.
A:AnswerIn your Roku account you can connect multiple devices to it allowing you to set up your second tv to the same settings and operations as your first one. Setting up the second one to work like the first one can be done by choosing the same settings in Roku as you did for the first one.
A:AnswerThat's why most of us buy this tv . For the 4k. I dont believe you can turn it off. If that's not what you wanted, why not just buy a tv that's the same size but without the 4k.
A:AnswerRemote is small, similar to a Roku remote. Just 7-8 buttons.
Features, adjustments etc you would normally push a button for, are made on screen instead. Once you get proficient at using it, it works very well. Took me a few hours of practice.
