I have used my big screen for the computer monitor, If you are going to do that, using it’s built in wifi and not connecting a computer to it, I suggest getting a different remote that you can use. I got one similar to this one because using the TV remote when you need a keyboard and have to point with the mouse at letters, using arrows on your remote it takes forever... With this, you just start typing.

Awesome! Thanks. Might come in handy when instructing new to Q people. My husband had to watch Everything is a Rich Man’s Trick on my lap top.
