●● 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)

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.
