A 4K TV has a horizontal resolution of 4000 pixels.4K is the name used to refer to ultra-high definition television. 4K Ultra HD TVs provide four times the picture quality and resolution as 1080p full HD.4K offers images with more clarity, greater texture and fine detail and smoothness. The technology delivers eight million pixels.
Difference between 4K and Ultra HD
Ultra high definition is derived from the 4k digital cinema standard. Though 4K cinemas are displayed in 4096×2160 resolution, the new ultra HD TV has a reduced resolution of 3840×2160.For this reason, some TV manufacturers have been reluctant to use the 4k label on their products, preferring to use Ultra HD instead.
What makes 4K Ultra HD a good choice?
People who view images on an HD TV see only a fraction of the detail inherent in their pictures when they display them in 2160p.
With a 4k display you can see lots of detail that you will not fail to notice the clarity this new technology offers.
The high pixel density of a 4K screen enables users to watch a much larger screen .Currently most 4K ultra HD TVs are larger than 50-inches.
The first 4k TVs to hit the market were large. LG and Sony launched the 84LM960V and KD84X9005 respectively. Both televisions had 84-inch display panels. The TVs were retailing at $30000.Samsung soon launched the 85-inch S9 that came with a $55000 price tag.
However, 4K Ultra HD TVs prices have fallen with increased competition among leading TV manufacturers.The screen sizes have also reduced. It is possible to get a 4k Ultra HD TV for less than $1000.Buyers should choose TVs from reputable manufacturers because you can only get improved image details if the processing electronics used in the TV are good.
Currently, the popular 65-inch Sony KD65X9005B retails at $3000 and the price is expected to reduce.
How small will 4K Ultra HD TVs get?
It is expected that most screen sizes will be 55-inches and above. The reason is that as the size of the screen reduces, the advantage of the large pixel density diminishes.
The benefits of high frame rate Ultra HD broadcasting are not restricted to the large display panel sizes. It is expected that the size of 4K Ultra HD TVs will drop further.The Ultra HD technology also enhances improved contrast,fast frame rates and better colour display.Higher frame rates makes the images appear more natural and detailed.
How far should you sit from a 4K Ultra HD TV?
The best distance to watch a 65-inch 4K Ultra HD TV is 1.5m.TVs larger than that can be viewed at a distance of 2 or 3m.
