How can I reduce the minimum focus distance of a home theater DLP projector from 3 ft. to 1.5 ft?
I have an Optoma EP719 that I want to use as a rear-projector. But I only have 1.5 ft of clearance. The minimum focal distance for this projector is 3.9 ft. Does anyone know of a way to reduce the focal distance of a projector. Like attach a diopter/close up/wide angle lens.
