Term Description
MHL (Mobile Mobile High-Definition Link (MHL) is an industry standard for a
High-Definition mobile audio/video interface that lets you connect mobile devices
Link) such as smartphones and tablets to projectors and other HD video
displays. MHL is a consortium made up of major companies in the
consumer electronics industry, including SONY, Nokia, Samsung,
Silicon Image, and Toshiba.
MHz Megahertz. One million hertz or cycles per second.
Minimum The closest position that a projector can focus an image onto a
Distance screen.
Monitor An output on the projector or large-screen monitor that allows you to
Loopthrough connect additional monitors or projectors to display the same image.
Also known as "RGB out" or "VGA out."

Motion Any artifact caused by camera panning or object movement within
Artifacts video. Judder and combing are motion artifacts.
MPEG Moving Picture Experts Group. A working group of ISO/IEC in
charge of developing codecs and standards for moving pictures with
synchronized audio.
Multi-Lamp Some projectors use multiple lamps that can be controlled by the user to
increase or decrease the brightness of the image. This lamp redundancy
significantly minimizes the risk of total lamp failure during use. Another
type of multi-lamp system is a Dual Lamp. With a dual lamp projector
one lamp can serve as a backup to the other lamp in the event of failure
or the lamps can be programmed to switch at specific intervals.
Native Aspect Nearly every projector or display today will support multiple aspect
Ratio ratios; however, each manufacturer must decide who their intended
audience is and optimize the projector for that audience. This means
each device has a native aspect ratio that is optimized for specific
viewing material. Images shown in native aspect ratio will utilize the
entire resolution of the display and achieve maximum brightness.
Images shown in other than native aspect ratio will always have less
resolution and less brightness than images shown in native aspect ratio.
Native Native Resolution is the number of physical pixels in a display device.
Resolution For example, an XGA display has a native resolution of 1024 physical
pixels of resolution horizontally and 768 pixels vertically or 786,432
total pixels. See Maximum Resolution.
Negative Gain A screen with a gain rating of under 1 which actually reduces the
Screen amount of light reflected back from a projected image. Usually gray,
they are used to increase apparent contrast by lowering the black level.
Noise An unwanted random signal.
NSH New Super High pressure projector lamp is a short arc metal halide
lamp.
