This section briefly explains the difficult terms that are not explained in the
text of this guide. For details, refer to other commercially available
publications.
Aspect Ratio The ratio between an image's length and its height.
Screens with a horizontal:vertical ratio of 16:9, such as HDTV
screens, are known as wide screens.
SDTV and general computer displays have an aspect ratio of
4:3.
Contrast The relative brightness of the light and dark areas of an image
can be increased or decreased 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.
Full HD A screen size standard with a resolution of 1,920 (horizontal) ×
1,080 (vertical) dots.
HDCP HDCP is an abbreviation for High-bandwidth Digital Content
Protection.
It is used to prevent illegal copying and protect copyrights by
encrypting digital signals sent over DVI and HDMI ports.
Because the HDMI port on this projector supports HDCP, it
can project digital images protected by HDCP technology.
However, the projector may not be able to project images
protected with updated or revised versions of HDCP
encryption.
HDMI
™
An abbreviation for High Definition Multimedia Interface.
HDMI
™
is a standard aimed at digital consumer electronics and
computers. This is the standard by which HD images and
multichannel audio signals are digitally transmitted.
By not compressing the digital signal, the image can be
transferred at the highest quality possible. It also provides an
encryption function for the digital signal.
HDTV An abbreviation for High-Definition Television that refers to
high-definition systems which satisfy the following conditions:
• Vertical resolution of 720p or 1080i or greater (p =
Progressive, i = Interlace)
• Screen aspect ratio of 16:9
Pairing Register devices in advance when connecting with Bluetooth
devices to ensure mutual communication.
Refresh Rate The light-emitting element of a display maintains the same
luminosity and color for an extremely short time.
Because of this, the image must be scanned many times per
second 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 that refers
to standard television systems which do not satisfy the
conditions for HDTV High-Definition Television.
