Click on the Apple menu > System Preferences > Display > click on Resolutions and select 1920 x 1080, which is the default resolution used by most HD TVs. You also need to set the Aspect Ratio of your TV to 16:9 (the instructions are available in the manual provided with the device or on the manufacturer's website). These modifications must be performed before connecting your Mac to your TV set.

You can now connect your devices together and select your preferred display arrangement. This setting can be configured by going to System Preferences > Display > Arrangements. It should be noted that when you connect a secondary display to your Mac, it will automatically enable extended screen mode, which also means that both screens are being considered as a single desktop. Tick the Mirror Displays checkbox to disable the extended mode and display the same image on your Mac and TV screen.
