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

●

ARC (Audio Return Channel)

Generally, a separate RCA or optical cable needs to be connected in order for the TV audio to

be heard through an AV receiver. With receivers that support ARC, however, digital audio can be

transmitted via the HDMI cable only.

●

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.
