Projector off-axis function introduction: The projector off-axis function means that the projector screen will be presented on the same level as the projection lens; that is, the bottom edge of the projection screen and the projector lens will be on the same level. So far, the off-axis projector is also called a stand-free projector.
The off-axis function of the projector is divided into 100%, 80% or no off-axis. For a projector with a 100% off-axis, the screen will be kept at the same level as the lens; a projector with an off-axis of 80% will have some low screen images. on the lens.
The off-axis function of the projector: The off-axis function of the projector is mainly for the convenience that the projector can be directly projected on the desktop, so that it is convenient for the user to use directly. At present, most projectors support 100% off-axis, and only some LCD home projectors may have 80% off-axis. The projector without the off-axis function needs to be used with a bracket. When it is used on the desktop, half of the screen will be on the desktop and half of the screen will be on the wall. You can refer to the two pictures below.
