Traditional TV or HDTV must have effective response time. It is the amount of time a pixels in TV takes to go from one value to another and come back quickly. It is measured in milliseconds, lesser the time means faster transitions, 6 ms, 8 ms or up to 12 ms are considered better response time.
It is defined as the ratio of the brightest colour (white) and darkest colour (black) which produce the high contrast ratio for better images. If the TV contrast ratio is low then light images will be washed out and dark images will be look cloudy. For example 500 : 1 contrast ration means brightest white is 500x brighter than the darkest black.

Although, 2D TVs are less expensive as compare to the 3D TV, for watching any content on 3D TV you should have 3D glasses otherwise you will not be able to see the effect rather than overlapping/blurred motion images. The extra dimension in 3D lets thing (like a cricket match, racing, fighting game) monouvered like its coming towards you. But 3D lacks in terms of content availability cos making 3D movies is a costly affair.
Currently, all OEM manufacturers are showing their product USP via the network connectivity.

Technically, the difference between all these are as follows. The 576p can be used on analog PAL or SECAM systems, 720p is a progressive HDTV signal with 720 horizontal lines. Difference between 1080i & 1080p is that in 1080i splits 1080 in two interlaced fields of 540 lines, odd fields displayed first and even field displayed second. In 1080p both odd and even fields displayed together.
LCD, LED or Plasma?
Boxy, bulky CRT TV’s are on the edge of discontinuation. These days, there are three types of HDTVs available in the market, first one is LCD (also known as traditional CCFL-backlit LCD), LED (also known as LED-backlit LCD or LED-LCD, or just LED screens) and the last one is Plasma HDTVs.
