A:Answeri bought this for a monitor that my son uses with his macbook. the ports are a little tricky so you have to make sure you get the right connection to enable an hdmi port to be added to macbook. the macbook uses thunderbolt 3 so a decent port that plugs into that enabling regular hdmi connections will be needed.
A:AnswerI do not believe so. I have mine over five feet away from my tower, and the dongle is on the back side away from me. Have had no problems with it.
A:AnswerI'm not 100% sure. You might want to call Logitech support with that question. I did see other keyboards in Best Buy that seemed to be made for TVs. I would think your TV would need to have USB port and be able to detect and install driver(s) to be able to operate this keyboard (to use it.) There is the Unifying Receiver USB thing that comes with this ... I'm just not sure it will work with your TV or any TV.
A:AnswerI believe that you can use almost any keyboard and mouse that you want with your system but they do wear out after some time and you may just want a new one. This one is a good choice and is available in stores.
