Can any body explain the disadvantages of using a HD ready TV over the FULL HD ?
I want to buy a HD TV. I am confused about the technical details in the media.
Some people argue that the difference between 720p (HD ready TV) and 1080p (FULL HD) resolution cannot be seen on a screen width of 32" or less. It only makes a difference on a 40" and above screen width television.

Most of the HDTVs today are able to support 720i/720p/1080i/1080p signals. So the single most important spec that we should be looking for when choosing a HDTV is the screen resolution (pixel resolution).
For HD Ready HDTVs which have screen resolution less than 1920×1080, they are less than ideal. This is because if you feed a 1080i/1080p signal to a HD Ready HDTV, this HDTV will scale down the signal resolution to fit its smaller screen resolution. That is to say, you will lose resolution if you use a HD Ready HDTV to display a 1080i/1080p signal.
For Full HD HDTVs, they have screen resolution of 1920×1080, thus, when a 1080i or 1080p signal is feed to it, it is able to display the picture in its full glory at 1920×1080 with no resolution loss.
So it is not difficult to conclude that if money is not a problem, always go for Full HD 1080p HDTVs with 1920×1080 resolution instead of HD Ready 720p HDTVs which has lesser resolution.
GOOD LUCK
In simple words, HD Ready will not try to relay HD picture until reception is not proper and Full HD will try and relay HD pics as per quality of HD. And resolution of Full HD is automatically set. It is also true that Full HD is not available less than 32". Hence better go with Full HD for tension free future.
"HD ready" only means that a TV can receive an HD signal, but will display it only in low resolution. "Full HD" will actually show the higher resolution. Go for the Full HD you won’t regret it.
HDTVs contain an HD tuner allowing you to receive high definition, for example from your house antenna’s over the air signal reception.
HD_READY TVs contain everything necessary to display high definition except that HD tuner. To display high definition, you need a separate high definition tuner box (ca. $300) or cable (or other service) which provides a high definition digital cable box which does the tuning for high definition for you.
To be little more precise and to add a caution…
An HDTV is a television that is designed to receive and properly display television signals in either of the two ATSC (Advanced Television Systems Committee) broadcast formats: 720p and 1080i. The native resolution of the television should be either 1080 pixels or 720 pixels, but it might be lower in cheap sets (e.g., 480). A television with a native resolution of 1080 will upsample and interlace a 720p signal. One with a native resolution of 720 will downsample and deinterlace a 1080i signal. An HD-compatible television with a resolution of 480 will need to downsample both 720 and 1080 pictures.
An HD-ready television is… a television. The term "HD-ready" means absolutely nothing in terms of television capabilities, although it certainly implies something better than the norm. Some manufacturers may produce a high-resolution television without an HDTV tuner, while some might label their run-of-the-mill television HD-ready because you can connect the output of an HDTV tuner to their inputs. This presents a problem to unwary consumers, who may not be aware that the television they buy has no special HD features.
This kind of labelling is all too common, unfortunately, and misleads many consumers. When digital music – the CD – first appeared, many companies branded their amplifiers and speakers as "digital ready". These products seemed to offer something special, but nothing had changed except for the word "digital" on the label. Today you see photography equipment branded in the same fashion. A "digital tripod" is a normal camera tripod with the word "digital" added – it does nothing special to earn that moniker.
