Roku TVs and sticks have a secret menu! To get to it, you press buttons on the remote sort of like the secret combo codes on old video games. For example, press the home button 5 times. Then press up, right, down, left, up. You’d think it was to make Ryu to throw a fireball in Street Fighter. But, no. It’ll take you to a menu that is literally called “Secret Screen 2”. When there, you can shut off that giant ad that shows up on the right side of your home screen.
There are a couple of other secret menus. This video gives directions on how to get to them.
