That was 2003. Today, full HD 1080p is ubiquitous. Nearly 75 percent of Americans own HD televisions, and the most popular computer monitors are HD, according to a study (http://www.leichtmanresearch.com/) by the Leichtman Research Group. From a technologist’s perspective, that’s an encouraging evolutionary trend. Manufacturers of displays see things differently, however. In their eyes, familiarity breeds yawns, which translates to lower sales. So, in an effort to once again awe the masses with technological magic, television and smartphones makers are rushing to mass-produce displays of unprecedented resolution. The most popular target by far is 4K, which has a minimum resolution of 3840 x 2160 . Nearly every major TV manufacturer has released a 4K model, and LG recently teased a 5.5-inch mobile display (http://www.androidauthority.com/full-hd-2560-x-1440-quad-hd-lcd-smartphones-lg-display-257710/) that, while not quite 4K, comes impressively close. (It has a resolution of 2560 x 1440 (http://www.androidauthority.com/vivo-xplay-3s-284146/).) Another display manufacturer out of Japan named Ortus Technology has demoed (http://www.theverge.com/2012/10/25/3552840/worlds-smallest-4k-display) a 9.6 inch 4k display, too.
The Benefits and Disadvantages of 4K
The main benefit of having the ability to capture 4K video is that you’ll be able to create stunningly detailed videos, that offer substantially better video quality. 4K video is video that is captured at a resolution of 3840 x 2160 vs 1080p’s 1920 x 1080. It’s over 8 million pixels with 4K vs 2 million with 1080p. Massive difference.
4K is a huge boon for those proficient in video editing, because of the nature of the resolution. It, if we recall, offers four times the resolution of 1080p. That means cropping without significant loss of resolution; conceivably, an edited video missing a significant amount of captured video could still qualify as HD.

Watch our Samsung Galaxy Note 3 review, here. (http://www.androidauthority.com/samsung-galaxy-note-3-review-278582/)
The Note 3′s 13MP BSI camera, is capable of capturing true, honest to goodness 4K video. With a resolution of 3840×2160, it shoots glorious 4K video at variable frame rate of 26-35fps. The video length is somewhat expectedly capped at five minutes, and produces a whopping 1.5GB file. The bit rate of the video itself is approximately 48-50mbps. And while each experience won’t necessitate employing the 4K detail the Note 3 is capable of, it’s nice to be able to grab such incredible video from your smartphone whenever an exciting moment beckons.

4K content is insanely sharp. If you’ve ever witnessed it first hand on a 4K capable display , you’ll know that it’s an order of magnitude sharper than 1080p, so in a word: stunning. It also allows for zooming without apparent loss of quality. (Think Nokia’s 42-megapixel Lumia camera, but for video.) Of course, a PC (or powerful mobile device) and software powerful enough to handle 4K footage is a necessity, but given the downwardly trending price of virtually all consumer electronics, it’s likely an upgrade probably isn’t an outrageous proposition for those able to afford a 4K-capable Android phone.
The Qualcomm Snapdragon 800 – the world’s first 4K capable SoC
Clarity should be the primary benefit of 4K – more pixels is good in theory – but comes at a price. Recording 4K videos will consume substantial battery life and the files themselves will be massive. Qualcomm, the first company to produce an SoC (the Snapdragon 800) capable of capturing 4K footage, hasn’t been forthcoming about the compression and bitrate used. It isn’t unreasonable to assume, though, that the quality won’t be on par with what cameras like the RED Epic can produce. Just like smartphones won’t replace DSLRs for video any time soon, don’t expect to see Hollywood blockbusters filmed on the Note 3. Further research shows however, that the 4K footage grabbed by the Galaxy Note 3 is around 50mbps resulting in significantly larger file sizes than the 1080p video most smartphones are capable of capturing, today.
The Bottom Line

There’s no doubt that 4K is the future. Ultra HD / 4K recording and content have the capability to redefine our media experience – though mainstream adoption is still a few years off. With current 4K displays starting to trickle onto the market with premium pricing attached, it’s likely that mass adoption will have to wait until pricing hits consumers’ sweet spots. Over the next several quarters, we’ll see more reasonably priced 4K cameras and smartphones with this feature hit the market. It’s only a matter of time before 4K, in all the glorious detail that it brings, is mainstream.
And how about you? Are you planning on getting a 4K television? Do you think 4K video is overkill? The consumer electronics industry is gearing up for it in a big way, and even has plans for 8K and beyond. Let us know what you think down below!

Primero que nada, ya creo que la potencia de los celulares de alta gama es IMPRESIONANTE. Hasta exagerada en cierto punto.
No veo necesario que metan 4k para un smartphone, NO SE NOTA LA DIFERENCIA EN UNA PANTALLA DE 6'
Pero bueno, es lo que se va a venir...
