How do you check your TV's settings for mirror devices?
Make sure your TV allows connections from other devices.
For Samsung TVs, you need to turn off "Access Notification" for Screen Mirroring. A known problem for screen mirroring to Samsung TVs has to do with the ‘Access Notification’ setting.

On your LG TV, there will be a setting that lets the TV be found by the Mirror for a LG TV. This is what it looks like on WebOS based LG TVs:
On other LG TVs (older models) you will find the same setting, but it might be called DLNA DMR (Digital Media Renderer) ON or OFF.
To allow the Mirror for LG TV app on your Mac to find your LG TV, always set this to ON.
In order for our screen mirroring app to work on your Panasonic Smart TV, please follow the instructions below.
For the latest Panasonic TV models, enable DMR (Digital Media Renderer) in TV Settings: With your remote control, go to: Menu / Setup / Network / Application / DMR: ON
Some of the latest Sony TVs are based on the Android TV operating system. In some cases, some of the services running on the TV, under Android, stop working. The only way to resolve this is to do a full power cycle reboot on the TV. (Unplug the TV from the AC power source, wait 5 seconds, then plug it back in again).
The services will restart and you can now use the Mirror to connect to the Sony TV .
For other TVs, check to make sure they can be connected to other devices. If your TV is connected through a powerline adapter, most powerline adapters create a separate subnet, which means that your Smart TV will not be able to reach your Mac to get the screen mirroring video stream. Please connect your TV in the same way to your router as your Mac is connected to your router.
