Projector screen set up is the final step for your home theater
It takes some planning to get your projector screen set up to get the perfect location. You’ll first have to consider the location of the projector. Most projectors are designed to have the middle of the lens project just a bit above the bottom edge of the screen.
You’ll want the ideal set up for your projector screen. The standard set up for the ideal height for a squared off image is to have the projector rest on a small table in front of the screen. Projectors with a vertical lens shift will have more flexibility and range. Since you won’t be able to sit in the path of the light beam, you may consider mounting the projector on the ceiling for more space.
The next step is finding the perfect location for your screen.
Placement is crucial
The bigger that projection, the better the picture but you will need to put the screen further away. The minimum size the image can be is approximately 30″ (0.8 m) measured diagonally when the projector is roughly 4 feet (1.3 m) from the wall or screen. The largest the image can be is 500″ (12.7 m) when the projector is about 80.83 feet (24.64 m) from the wall or screen. Consult the drawing below as a guide.
Throw Distance and Screen Size
Each screen has an aspect ratio. The most common options are typically 16:9 or 4:3. Make sure your screen’s aspect ratio matches your projector’s for the best possible viewing experience.
The ideal screen size takes into consideration both the width and depth of the viewing room. The biggest consideration for setting up your projector is the throw distance, which is the proportion of width and height of an image projected onto the screen.
It’s typically expressed as numbers, such as 4:3, but these numbers ARE NEVER the size of the screen. You will need to calculate the distance of the projector and then adjust it with the projector turned on.

Authentic projector lamps keep your projector working
Projector lamps operate with a lamp driver with a 5kV ignition voltage. Lamps with metal antenna in the ignition chamber are 5kV lamps. Some lamps have their antenna in the front while others have the antenna in the rear. Some projectors need high ignition voltage of 20kV so have no antenna. Generic manufacturers often don’t have the specs needed to create the proper antenna for each projector lamp and instead create lamps that faulty antenna that short circuits in the projector.
Projector lamps also work with the projector driver to bring the image to the screen. The combination of lamp and driver is unique to each projector model. Only authentic manufacturers know the specifications for each particular brands and how to use those specification to create OEM lamps. Generic lamps can never have the correct combination and installing them creates unbalanced electrical power with danger of explosions.
Almost all projector lamps have the same outer shape but the inner shape is dependent on the projector model. Most generics don’t have the correct specifications to create the correct inner shape. It creates a lamp with uneven light output distribution.
