The SmartProjector's autofocus feature ensures that the projected image is as sharp as possible without the user having to manually adjust the projector's focus.

There are three ways to enable Autofocus on TCL SmartProjector:

1. Turn on Autofocus by going to Settings > Projector > Focus > Auto Focus
2. Slightly Shake the projector to trigger the autofocus mechanism. 
3. Press and hold the FOCUS button on the remote to trigger autofocus.
