480i/480p/720p/1080i/1080p
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.
* General differences between 480i and 480p are as follows:
480i 480p
Horizontal Frequency
15.75Khz 31.5Khz
FPS
30 60
Lines on Screen
480 480

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-DVI 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.
