Hello bum4evr,
Thanks for your inquiry.
Even though the terms “casting” and “screen mirroring” are commonly interchanged in the industry, there are differences when using them with your Roku device.
Could you tell us what are you trying to do? Do you wish to cast to your TV what you are already watching on your mobile device, using the casting icon? Or do you want to replicate (or “mirror”) the screen of your compatible Android or Windows device wirelessly onto your TV screen?
To learn more about the difference and instructions, read the articles below:

Keep us posted on what you find out.
