I have hooked my MacBook Air up to a TV via HDMI connection but all I get is random pictures like screen saver pictures. How can I mirror the computer screen so that I can use a projector to show movies?
Select the control panel icon (leftmost below), then screen mirroring.
Or, go to System Preferences > Displays
Please know that your display needs to use a secure HDMI connection (HDCP) to be able to stream protected content.
