hi i want to know that what is the major difrence between FULL HD 1020 LCD tv and HD READY 720 TV. As full HD tv sony bravia cost lot more then HD Ready so what u sugest for pakistani buyers to go for full HD or HD ready will work sa there is nofull HD chaneels in pakistan.
firstly its 1080 not 1020.
Secondly there is no 720p channel here, let alone 1080p
^ In here who cares about Pakistani channels anyway, all they want is star plus, and that recently got upgraded to HD.
1080p = 1920x1080 resolution (~2 million pixels)
720p = 1280x720 resolution (~1 million pixels)
It depends on your input. Consoles for example can only go upto 720p and upscale the rest which means there's almost no difference between 1080p and 720p. You can get 720p and 1080p movies on torrents but 1080p movies are huge. I don't know if the HD channels being offered by DTH companies are 1080p or 720p.
Firstly as mentioned there are no HD channels in Pakistan and won't come anywhere in near future.
Ok as far as HD ready tvs go it is well known fact that in small screen you won't be able to find any difference in quality, a slight minimal amount of difference arises when you switch to like 40"+size. This happens in fast moving scenes. Remember our naked eye can't detect this difference easily.
HD ready tvs these days are capable of delivering 1920x1080 resolution with 720p pixels (known as upscaling from 720p to 1080i), this further reduces the difference between the full hd and hd ready tvs.
As far as channels go according to my knowledge there isn't a single channel broadcasting in 1080p, all are making use of 720p resolution because the bandwidth requirement is too much for 1080p.
So, if you are crazy for watching movies in Blu ray quality (Full HD) and want perfect quality than go for full hd tv. If you are primarily going to use it for watching geo tv than don't bother wasting your money over full hd.
A company's 1080p TV is a way of making their product appear like it is way better than 720p. Just like the Megapixel race, Megapixels only make a difference when the image is printed on large posters.
720p is sufficient for fulfilling the High Defination crave.
1080i vs 720p: What's better?
Many users may be confused whether to select 1080i or 720p on their HDTV receivers - in order to achieve the best high-definition pictures.
The identifier of quality is the "i" and the "p" in the resolution, "i" standing for Interlaced and "p" standing for Progressive.
Interlaced technology has already been in use for many years, and is used for Standard Definition broadcasts, where half the resolution is virtual, meaning that the picture in split into 2 fields: 1 line with the resolution and 1 line
that is blank, these 2 fields interchange at such a rate faster than the human eye can see - that you see 1 frame.
This means you never have the full resolution available to you in "i" mode. You can particularly notice this on football games where the ball moves at such a speed there is not the full resolution to show the smooth and fast movement of the ball - leaving a ghosting movement or "interlaced artifacts".
Choosing "Progressive" video resolution means that the full image is available to you, with no artificial lines or artifacting. When you watch a film at the cinema or watch a Blu Ray Disc this will be "Progressive". Plus most High-Definition monitors and TVs are Progressive.
In comparison because of artificial lines 1080i offers 540 lines resolution at one time, where as 720p offers 720 lines with no tricks.
Currently broadcasters are only offering 1080i or 720p HDTV broadcasts. So when you see x1080 in the video properties on your set-top box this refers to Interlaced resolution.
So this is the order. The top one is best.
1080p (progressive) (not exists on current LCD's)
720p (progtressive) (go for this one as its best) (better to stay with this one)
1080i (Its 720 but above that all is virtual)
480p (it's enhanced high definition not actual HD)
480i(it's standard definition)

World's First Ultra High Definition LCD Display
On the 15th of May, Sharp in collaboration with NHK unveiled the world's first Ultra High Definition-capable LCD display.
This 85" LCD display has a resolution of 7,680 x 4,320 pixels, which is equivalent to 16 times the resolution of HDTV, allowing for the display of incredibly detailed, high-quality images.
In the past the only way to show the Ultra High Definition broadcast at full resolution was using a projector, but due to Sharp's UV2A LCD technology, which allows for an unprecedented level of precision when controlling the alignment of liquid crystal molecules in an LCD structure, Sharp have been able to create a flawless 33megapixel display.
By using Sharp's Aquos technology as well as video processing technology first shown in Sharp's Multi-Screen Display system released in June 2010, the display supports 10-bit color depth for each channel as well as refresh rate of 60Hz.
NHK are working to begin trial broadcasts of this next generation broadcast format in the year 2020.
This 85" Ultra High Definition display will be shown to the public for the first time at NHK's Science and Technology Research Laboratories in Tokyo from the 26th to the 29th of May, 2011.
