Tips & Warnings
Read the projector's manual for its operation and extra feature to operate. Always distance the projector from the computer to avoid interference. Provide enough ventilation space around the projector. The lamps can get very hot.
Never handle the cables with the power supply connected to both computers and projector. Do not use projectors for viewing movies on a regular basis, as that can diminish the life of the costly lamp in the projector.
