DHCP — Dynamic Host Configuration Protocol — A network protocol that enables a server to
automatically assign a TCP/IP address to a device.
DLP® — Digital Light Processing™ — Reflective display technology developed by Texas Instruments,
using small manipulated mirrors. Light passing through a color filter is sent to the DLP mirrors which
arrange the RGB colors into a picture projected onto screen, also known as DMD.
DMD — Digital Micro-Mirror Device — Each DMD consists of thousands of tilting, microscopic aluminum
alloy mirrors mounted on a hidden yoke.
Focal Length — The distance from the surface of a lens to its focal point. Frequency — It is the rate of
repetition in cycles per seconds of electrical signals. Measured in Hz (Hertz).
HDCP — High-Bandwidth Digital-Content Protection — A specification developed by Intel™ Corporation
to protect digital entertainment across digital interface, such as DVI, HDMI.
HDMI — High-Definition Multimedia Interface — HDMI carries both uncompressed high definition video
along with digital audio and device control data in a single connector.
Hz (Hertz) — Unit of frequency.
Keystone Correction — Device that will correct an image of the distortion (usually a wide-top narrow-
bottom effect) of a projected image caused by improper projector to screen angle.
Maximum Distance — The distance from a screen the projector can be to cast an image that is usable
(bright enough) in a fully darkened room.
Maximum Image Size — The largest image a projector can throw in a darkened room. This is usually
limited by focal range of the optics.
Minimum Distance — The closest position that a projector can focus an image onto a screen.
NTSC — National Television Standards Committee. North American standard for video and broadcasting,

RGB — Red, Green, Blue — typically used to describe a monitor that requires separate signals for each of
the three colors.
SECAM — A French and international broadcast standard for video and broadcasting, closely related to

SVGA — Super Video Graphics Array — 800 x 600 pixels count.
SXGA — Super Extended Graphics Array, — 1280 x 1024 pixels count.
UXGA — Ultra Extended Graphics Array — 1600 x 1200 pixels count.
