Generally
refers to the number
of effective
scanning
lines that determines
the screen's
resolution.
There are two scanning
methods:
interlaced
and progressive.
-
Scanning
Sequential
projection
of pixels to form
images.
The higher the number
of pixels,
the clearer
and more vivid the images.
-
Progressive
A sequential
scanning
method
that scans every line, one after another.
-
Interlaced
A staggered
scanning
method
that scans every other
line until the end of the screen and then
fills in the remaining
lines.
Example)
If the number
of horizontal
scan lines is 480i
Scans 240 lines from start to finish
and then scans the remaining
240 lines for a total of 480
lines.

ARC (Audio
Return Channel)
ARC lets the TV output
digital
sound to an audio device and input digital
sound from the same
audio device through
one HDMI cable. However, ARC is only available
through
the HDMI (ARC)
port and only when the TV is connected
to an ARC-enabled
AV receiver.
DVI (Digital
Visual
Interface)
Connecting
the TV's DVI connector
to a computer's
DVI connector
via an HDMI-to-DVI
cable
lets you use the TV as a computer
monitor.
However, HDMI-to-DVl
cables deliver video signals
only. You must connect
a set of speakers
to the computer
using a separate
cable to hear the
computer's
audio.
HDMI (High Definition
Multimedia
Interface)
HDMI is a method
of transmitting
both video
and audio signals
via a single
cable.
