Get the right height - HD Video Projector Wall

Get the right height - HD Video Projector Wall

For this how-to, we're assuming you're using the most common projection orientation: a table mount from the front. The concept is similar for ceiling mounts, however. If you don't get the height correct, the image will be trapezoid-shaped. That might not be a huge deal for you, but if you're trying to perfectly match the edges of a screen, it can be frustrating or impossible.

Most projectors have an "upwards throw." What this means is the image is projected above the center of the lens. How much higher varies depending on the model. This is good for placement on a coffee table, or mounting on a ceiling, as the image will be close to the center of the wall or screen, even though the projector itself is closer to the floor or ceiling. 

However, this means that placing a projector on a stand behind you is a challenge, since the image will now be projected on the upper part of the wall and probably the ceiling. If this is the placement you want, check out projectors with either lens shift, or no upwards throw.
