Mirrored display
So I have the Mac display on my Roku TV but it only shows the system preferences>displays tab on the screen. Not very useful! What am I doing wrong?

Hello AlliFyfe,
Let's use the steps below to see if that behavior persists while the mirror option is set:
1. On your Mac, choose Apple menu> System Settings, then click Displays
in the sidebar.
2. Click the name of your display on the right, click the “Use as” pop-up menu, then choose Mirror for Display.
You can also find those steps in this resource: Use one or more external displays with your Mac - Apple Support
Should that still persist, are you experiencing the same behavior with other external displays?
Let us know, and we'll keep moving forward from there.
