GlossaryThe following is an explanation of some of the terms used in this guide which may be unfamiliar or which are not explained in the text of this guide itself. Further 
information can be obtained by referring to other commercially-available publications.
Aspect ratio
The ratio between an images length and its height. HDTV images have an aspect ratio of 16:9 and appear elongated. The 
aspect ratio for standard images is 4:3.
Color Temp.
The temperature of an object that is emitting light. If the colour temperature is high, the colours take on a bluish tinge. If the 
colour temperature is lower, the colours take on a reddish tinge.
Component video
Video signals which have the video brightness signals and colour signals separated, in order to provide better image quality. 
In high-definition TV (HDTV), it refers to images which consist of three independent signals: Y (luminance signal), and Pb 
and Pr (colour difference signals).
Composite video
Video signals which have the video brightness signals and colour signals mixed together. The type of signals commonly used 
by household video equipment (NTSC, PAL and SECAM formats). 
The carrier signal Y (luminance signal) and chroma (colour) signal which are contained in the colour bar are overlapped to 
form a single signal.
Contrast
The relative brightness of the light and dark areas of an image can be increased or decreased in order to make text and 
graphics stand out more clearly, or to make them appear softer. Adjusting this particular property of an image is called 
contrast adjustment.
Dolby Digital
A sound format developed by Dolby Laboratories. Normal stereo is a 2-channel format which uses two speakers. Dolby 
Digital is a 6-channel (5.1-channel) system which adds to this a centre speaker two rear speakers and a sub-woofer.
EMP Link 21L
A utility software program that allows the projector to be connected to a computer so that the computer can be used to control 
the projector. For details on acquiring the software and for instructions on using the software and compatible projector 
models, go to http://www.epson.com and select the Support section of your local EPSON website.
HDTV
An abbreviation for High-Definition Television. It refers to high-definition systems which satisfy the following conditions.
 Vertical resolution of 750p or 1125i or greater (p = progressive
g, i = interlaced
g)
Screen aspect ratio
g of 16:9
Dolby Digital
g audio reception and playback (or output) 
Interlaced
A method of image scanning whereby the image data is divided into fine horizontal lines which are displayed in sequence 
starting from left to right and then from the top to the bottom of the screen. The even-numbered lines and odd-numbered lines 
are displayed alternately.
Progressive
A method of image scanning whereby the image data from a single image is scanned sequentially from top to bottom to create 
a single image.
Refresh rate
The light-emitting element of a display maintains the same luminosity and colour for an extremely short time. Because of this, 
the image must be scanned many times per second in order to refresh the light-emitting element. The number of refresh 
operations per second is called the refresh rate, and is expressed in hertz (Hz).
SDTV
An abbreviation for Standard Definition Television. It refers to standard television systems which do not satisfy the conditions 
for High-Definition Television.

Glossary
Security lock
A device consisting of a projector case with a hole in it that a commercially-available theft-prevention cable can be passed 
through in order to secure the device to a table or pillar. This projector is compatible with the Microsaver Security System 
manufactured by Kensington.
Squeeze mode
In this mode, wide-screen images in 16:9 mode are compressed in the horizontal direction so that they are stored on the 
recording medium as 4:3 images.
When these images are played back by the projector in squeeze mode, they are restored to their original 16:9 format.
sRGB
An international standard for colour intervals that was formulated so that colours which are reproduced by video equipment 
can be handled easily by computer operating systems (OS) and the Internet. If the connected source has a sRGB mode, set 
both the projector and the connected signal source to sRGB.
SVGA
A type of video signal with a resolution of 800 (horizontal) × 600 (vertical) dots which is used by IBM PC/AT-compatible 
computers.
S-Video
A video signal which has the luminance component and colour component separated in order to provide better image quality. 
It refers to images which consist of two independent signals: Y (luminance signal), and C (colour signal).
SXGA
A type of video signal with a resolution of 1280 (horizontal) × 1024 (vertical) dots which is used by IBM PC/AT-compatible 
computers.
Sync (synchronisation)
The signals output from computers and RGB video equipment have a specific frequency. If the projector frequency does not 
match this frequency, the resulting images will not be of a good quality. The process of matching the phases of these signals 
(the relative position of the crests and troughs in the signal) is called synchronisation. If the signals are not synchronized, 
problems such as flickering, blurriness and horizontal interference can occur.
Tr a c k i n g
The signals output from computers and RGB video equipment have a specific frequency. If the projector frequency does not 
match this frequency, the resulting images will not be of a good quality. The process of matching the frequency of these 
signals (the number of crests in the signal) is called tracking. If tracking is not carried out correctly, wide vertical stripes will 
appear in the projected images.
USB
An abbreviation for Universal Serial Bus. USB is an interface for connecting personal computers to peripheral devices which 
only support relatively low data transmission speeds.
VGA
A type of video signal with a resolution of 640 (horizontal) × 480 (vertical) dots which is used by IBM PC/AT-compatible 
computers.
XGA
A type of video signal with a resolution of 1024 (horizontal) × 768 (vertical) dots which is used by IBM PC/AT-compatible 
computers.

List of ESC/VP21 CommandsCommand List
When a power on command is sent to the projector, the power will turn on 
and the projector will change to warm-up mode. When the power has 
turned on, a colon : (3Ah) will be returned.
When the projector executes a command, it returns a : and waits for the 
next command to be sent.
If command processing terminates with an error, the projector outputs an 
error message and then returns the : code.
* When issuing any of the above commands, tack a Carriage Return (CR) 
code (0Dh) on to the end.
