4.4.2 Image focusing
Make sure the projector is horizontal to the projector screen and adjust the focus by pressing
button 2.
You can display video or the menu to check adjustment.
DISPLAY SOLUTION
The projector uses an optical keystone correction function, so the image can be adjusted as
below:
However, this projector does not have a horizontal keystone correction function. The projector
must be placed horizontally to the projection screen. If you encounter this problem, it is
probably because the projector has not been placed horizontally to the projection screen, or the
projection screen is not vertically positioned.
Solution: Adjust the projector's position so that it is horizontal to the screen.
