Every thing we Need to Know about 4K Technology

Every thing to know about 4K

So far we have experienced the visual technologies HD, FullHD, Ultra HD. The trend changes one to another, we felt amazing experience, particularly in Television viewing. When we reveal our past, nearly some tens of years back we started our display resolution experience at 480p. When personal computers entered in the field and improving them in technical aspect, then onwards the revolution of Display Resolution is begun.

Let us look into the scenario of Display Resolutions

Standard-Television Definition (SDTV)
480i (NTSC-compatible digital standard employing two interlaced fields of 243 lines each)
576i (PAL-compatible digital standard employing two interlaced fields of 288 lines each)

Enhanced-definition television (EDTV)

480p (720 × 480 progressive scan)
576p (720 × 576 progressive scan)
High-definition television (HDTV):
720p (1,280 × 720 progressive scan)
1080i (1,920 × 1,080 split into two interlaced fields of 540 lines)
1080p (1,920 × 1,080 progressive scan)
Ultra-high-definition television (UHDTV)
2160p (3,840 × 2,160 progressive scan; aka “4K UHD”)
4320p (7,680 × 4,320 progressive scan; aka “8K UHD”)

What Exactly 4K means

4K TV is a title used to describe any TV display technology that offers a total pixel count, which offers 4 times the final resolution that you’d find in ordinary Full HD TVs. A 4K TV doesn’t exactly need to have 4,000+ pixels in horizontal pixilation. Instead, with are solution of 3,840 x 2,160 (as most 4K TVs have, it already offers 4 times the resolution of 1920 x 1080p typical Full HD displays; though some 4K TV models do indeed offer even more than 4,000p horizontal resolution.

These include much better frame rates than normal HD TV, the ability to upscale regular HD video, far crisper color palettes and contrast ratios and full 3D TV capacity in most cases.
However, what really produced an absolute “wow” factor on a 4K TV is the experience of seeing native 4K content that was filmed with that pixel count in mind on your screen. Many users have claimed that this alone makes them never want to go back to normal HD.

What’s the Difference Between 4K and UHD?

UltraHD and 4KIn practical terms as far as branding is concerned, there is no difference between UHD and 4K. Inmost cases, TV manufacturers use the two terms interchangeably to describe the same 4K technology. However, if we’re speaking strictly, 4K is different in the sense that it has to consist of display resolution at least four times greaterthan that of normal 1080p HD and by its own industry standard it isspecifically defined as 4096 x 2160 pixels (at a 1.9:1 aspect ratio).

UHD, on the other hand, can be used to describe any resolution range that’s considerably larger than normal 1920 x 1080 Full HD.
So for example, any type of TV resolution that doesn’t reach 4K levels, but does give you, say twice the pixel count of 1920 x 1080p would also be considered UHD, and further more, any resolution that goes way beyond even 4K TV, such as saying 8K technology at7680×4320 pixels would also be considered UHD.

In fact, there are also several types of informally defined 4Kresolutions such as those with pixel counts of 4096 × 2160p or 3996 × 2160p. The bottom line is that 4K is a format which outstrips pretty much anything else currently commercially available for the consumer market.

4K Content and Regular Content

For the moment, actual native 4K content for your would be UHD TV is still pretty rare. In native 4K for viewers with the TVs and a fast internet connection, and Broadcasters in the UK and Japan are working on unveiling nationwide 4K broadcasting channels.

Sample 4K Video from YouTube

However, for now, most of your enjoyment will probably come from seeing the enhancements your TV offers to conventional HD content, which, according to some users are definitely noticeable (though others disagree on this). At the very least, having your TV, you’ll be ready to enjoy any new UHD content that will almost certainly be emerging at an accelerated pace over the next couple of years.
