on.
• If the projector does not respond when you press buttons on the remote control, make sure the remote
and projector are within range of each other.
• If you are projecting from a computer, make sure it is set up to display on an external monitor. If the
computer's display is set to an extended or mirrored mode, try changing it to external output only.

limits. If necessary, select a different display resolution for your computer. (See your computer manual
for details.)

copyrighted videos with updated or revised versions of HDCP encryption.
• If you are trying to view online content, make sure you have an active Internet connection.

Settings menu.
