What exactly is 4K?
First thing : what is hd television ?
High definition television provides a better resolution than standard resolution Tv .
We get much better picture quality,smoother motion,vivid and richer color and no more blurry images.Till recent HD television had two standards : 1920 x 1080 lines of pixels (known as Full HD ) and 1366 x 768 (known as HD Ready). Now we have 4k resolution.
Technically speaking, the word 4K signifies a display resolution of 4096 x 2160. It has an HD resolution of almost four times higher than the full HD resolution of 1920 x 1080 which is the current consumer standards of high definition.
The 4K is now officially designated for consumer products such as the Ultra HD or Ultra High Definition, but at the same time is also used in the professional or commercial settings as 4K x 2K, Quad High Definition, or 2160p.
Why do we need 4K?
It goes without a doubt, that 4K resolution gives the pleasure of watching television a whole new meaning taking it to a completely new level.More pixels you have, the better the image, not to forget the smoother finesse appearance of curved and diagonal lines.
Moreover, the high pixel count also allows enlarging the images without breaking them or distorting it thus suiting the luxurious trend to bigger TVs.
The new Ultra HD already seems to be making big its way into the world of digital cinema with almost all major Hollywood movies as well as television shows now being filmed in either 4K or even 5K for that matter.
This leads us to the next obvious question….what is the main difference between the 720p ,1080p and 4K Tv resolution ? Well the answer is about two meters. An increase in the density of the pixel (tallking about 1080p vs 720p tv sets ) allows you to sit closer to your TV without actually making the pixel grid so obvious. Thus the Ultra HD, with a 2160p image enables its viewers to sit as close as 1.6m from the screen.
What others are saying about 4K?
According to Forbes, the 4K will not most definitely provide its viewers a complete entertainment experience. Moreover, gaming and the other interactive activities are one of the many reason why a 4K TV will most likely become a hit instantly causing its viewers to give up on the luxury of sofas and couches and come within six feet of their TV set.
Watch a 4K video , or play a 4k game ??
For now there is no sign of 4K TV channels,but gamers and movie fans are the first to benefit from Ultra HD technology :
Sony will launch a range of Blu-ray discs optimized for 4K resolution TV sets produced by them.Although it will be not true 4K resolution, it will give a chance to watch something on your brand new Tv set.The main reason for not producing true 4K Blu-ray discs is movie size : 4k movies can have 200 gb !!
Sony PlayStation 4 will output ultraHD videos ( 4k) , but gamers will be dissapointed : 4K gaming is not available for the long awaited console.
PC videocards supporting 4k resolution are ready to be put to the test.Time will tell if games like Battlefield 3 or Crysis can run smooth at a decent FPS on a 4k TV .
Also,many current movie cameras such as the RED Epic can already film above 4K resolution and even at a 5K resolution of 5120 x 2700 while the Sony F65 8K on the other hand films at 8192 x 4320.
4K Tv price
Nonetheless, being the latest hype of the century, the 4K is most likely to cost at least twice as much as a top-end 1080p hence it’s always sensible to wait for a while, just until the prices drop a bit. Let's just say that buying a 4k Tv now will leave you with an empty bank account ..For example,the price for a 4k Tv set from Samsung ,Lg or Sony is similar to the price of a brand new sedan car.
But those who are in urgent need of and cannot resist getting their hands on this ultimate display for gaming as well as watching ,may find that the pixels are just about starting to add up.
