For stereoscopic 3D, a single-image system can only display the left-eye or right-eye image at once, switching between them at 90–144 Hz, though this does have the advantage of reduced crosstalk versus two-image 3D projection. Movie projectors typically use an incandescent lamp or arc lamp which does not itself flicker noticeably.
Such newer platter-based projectors would eliminate the need for cue marks, but the marks are still present on modern-day motion picture projection prints, mainly for older theaters and studio screening rooms still using two-projector setups, and also to aid the projectionist in identifying reel ends during the splicing together of the reels ...

Electric screens are usually raised or lowered using either a remote control or wall-mounted switch, although some projectors are equipped with an interface that connects to the screen and automatically lowers the screen when the projector is switched on and raises it when the projector is switched off.
Multi-monitor, also called multi-display and multi-head, is the use of multiple physical display devices, such as monitors, televisions, and projectors, in order to increase the area available for computer programs running on a single computer system. Research studies show that, depending on the type of work, multi-head may increase the ...
Unlike DLP projectors, however, SXRD projectors do not present the left and right eye images of stereoscopic movies sequentially, instead they use half the available area on the SXRD chip for each eye image. Thus during stereoscopic presentations the SXRD projector functions as a sub 2K projector, the same for HFR 3D Content. [40]

It is often necessary for a projector to be placed in a position outside the line perpendicular to the screen and going through the screen's center, for example, when the projector is mounted to a ceiling or placed on a table top that is lower or higher than the projection screen. Most ceiling-mounted projectors have to be mounted upside down ...
