Do I need to use a special projection cloth or can I project the image on a plain wall?
Although you can project onto a plain white wall, using a special projection cloth improves image quality, especially in terms of contrast and sharpness.
What is the lifespan of a projector lamp?
Lamp life is typically between 2,000 and 20,000 hours, depending on the type of lamp and how the projector is used.
