HD ready vs Full HD

I know i am going to get a HDTV one of these days because of my PS3 and Blu Ray functions.

So i did a little read up on the difference between HD ready and Full HD. How come there is a big price difference between a HDTV and a Full HD.

“An HD-ready panel has a resolution starting at 720 pixels, which allows HD viewing. But the full-HD screens have 1080p horizontal lines. And the more lines, the better the resolution, resulting in better picture quality and clarity,”

Movies on Blu-Ray disks are full-HD DVDs. When the Blu-Ray disk is played on an HD player into a full- HD television with HD cables, people will be able to see the 1080 resolution.

The below is extracted from http://www.squidoo.com/Full_HD_Ready_HDTV

HD signals
720i - 1280x720 interlaced
720p - 1280x720 progressive scan
1080i - 1920×1080 interlaced
1080p - 1920×1080 progressive scan

HDTV types
HD Ready - HDTV set capable of accepting HD signals (may not be able to display at full resolution 1920x1080)
Full HD - HDTV set capable of accepting HD signals and able to display full resolution at 1920x1080
720p HDTV - another name for HD Ready HDTV
1080p HDTV - another name for Full HD HDTV

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 1920x1080, 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 1920x1080, thus, when a 1080i or 1080p signal is feed to it, it is able to display the picture in its full glory at 1920x1080 with no resolution loss.

So in short, I should be hunting for a FULL CHEAP HD TV which allows me to view blu ray movie at 1080P..wohooo!
