Guide to High Definition

HD? What’s that then?
HD stands for High Definition, which is a fancy way of saying a pin-sharp picture and crystal-clear sound. Put simply, owning HD TV guarantees you a better quality of visual and aural entertainment.

Standard Definition (SD) TVs have a size of 720 x 576 pixels. HD TVs start at 1280 x 720 and go all the way up to 1920 x 1080.

In short, the more pixels on the screen, the finer the detail and the sharper the picture you can view – so a 720p or 720i HD TV will offer you more than a Standard Definition picture, but a less detailed picture than a 1080p or 1080i one.

What's with the 'i' and 'p'?
'i' is for interlaced, which refers to the way the TV populates its screen with information. A TV screen is made up of lines of pixels, and an interlaced format screen fills in the odd lines first, followed by the even lines. The end result is that you may spot a slight flickering, though it’s barely noticeable to the human eye.

'p' stands for Progressive signal, and is the more accomplished of the two formats. A progressive scan TV fills the whole screen with a picture all at once, making it the preferred option where possible.

So the logos next to your TVs tell me what I need to know before I buy?
Yup, that’s pretty much it. Here’s what they mean...

What do I need to make my console display in HD?
You can make your HD-powered console display a HD signal by plugging either a Component lead or a higher-quality HDMI lead from your console to the appropriate slot(s) on the back of your HD TV.
