When you're looking to buy a 150 inch projector, it's important to think about how you'll be using the machine. A shelf might not be necessary if you only plan on using the projector for occasional cinema screenings or displaying pictures from your wall-mounted flat screen TV. However, if you want to project large images onto a much larger surface, such as a wall, then it's best to invest in a mount or shelf specifically designed for projecting large screens.
Types of mounts and shelves
There are a few different types of mounts and shelves that work well with large projectors. The most common type is a pedestal mount, which attaches the projector to the wall using two screws or an arm that extends from the base. Shelf mounts attach to opposite corners of the wall, providing more stability for large projections. Many home theater owners prefer this type of mount because it allows them to position the projector closer to the screen for optimal viewing.
