A superb watch with Full HDTV

Feb 13, 2010

Today HD TV and HDMI are the new catchwords relating to TVs and we have being receiving several questions pertaining to them. We are presenting a couple of them and while answering them we have tried our best to simplify the subject.

Reader query: I was all set to go in for a LCD TV, but the sales guy was hard selling me HD ready or Full HD LCVD TV. I don’t know the difference. I am totally confused. Should I go in for a HD Ready TV or a full HD TV? What is the difference?

Columnist responds: HD stands for High Definition, which simply means that in HD TVs, the picture is more defined since the picture is created by more pixels and therefore has a better resolution than standard TV and therefore the picture is sharper and well-defined. The pixels determine the resolution of the picture and the number of distinct pixels in each dimension that can be displayed. In Plasma and LCD panel TVs, it is simply the physical number of columns and rows of pixels creating the display (eg. 1920×1080). Resolution is a bit of an ambiguous term since it is determined differently in conventional cathode ray TVs. Full HD TV — TV sets that capable of accepting HD signals and are able to display full resolution at 1920x1080 pixel HD Ready — TV sets capable of accepting HD signals (may not be able to display at full resolution 1920x1080), they can display a resolution of 1366x768 pixel and are therefore HD Ready and not Full HD. Size finally does matter. As a general guideline, if you are getting a HDTV set which is less than 42-inch, you won’t be able to notice the resolution difference between a HD Ready set and a Full HD TV. For the same screen size, Full HDTV’s cost much more than HD Ready TVs. If you are buying a TV less than 42 inches then going in for a HD Ready set instead of a Full HD set is an option. It will save you quite a substantial amount of money. Thus, you will be able to get almost the same visual enjoyment at a lower budget if you buy a HD Ready HDTV (768p) instead. For screen size 42-inch or greater, going for a Full HD (1080p) would be a better choice as in a big screen size, the pixel difference will be more visible.

Another common question we are asked is that new generation TVs are advertising TV with HDMI, what is HDMI and is it necessary to buy TV with HDMI inputs? We shall take this up in our forthcoming column.
