optimal resolution 4K ULTRA HD.

Ultra HD 4K is the last word we must learn in relation to the quality of the image on TVs. Since the appearance of television, the quality of the image has been increasing considerably with each new technology to reach what is currently called Ultra HD.

The evolution of the resolution of television screens from 1926 until now has been really impressive. From the 800 lines of the first SD TVs, through the first HD with 1080 px or the current Full HD technology with 1920 px. Now with the 4K we move to almost 4,000 px.

Ultra HD 4K Technology.

The Ultra HD 4K technology that can be found in the most current TVs is an improvement in the resolution and quality of the image that is 4 times more than that achieved by the current TVs with HD definition, reaching 3840 × 2160 pixels. Some, like LG, give it the name Ultra HD.
They are highly recommended TVs to enjoy the high resolution channels offered by some fiber optic platforms. Channels like Canal + already broadcast in this quality and YouTube allows recently upload videos with that resolution.

The name Ultra HD 4K (short for 4,000 pixels) was the big news at the Consumer Electronic Show in Las Vegas where the main companies presented monitors with very tight prices, € 500 compared to € 2,000 that were worth today.

Some television platforms are already creating content with this new resolution that some catalog of hyperreality for its great realism, something that will replace the unrealistic 3D television. The current 2014 Brazilian Soccer World Cup is already played and distributed in Ultra HD 4K.

Although the image quality is better in Plasma, it seems that everyone prefers LCD TVs, which with this technology results in devices that are increasingly real and ultra-thin, so the disappearance of Plasma is imminent .

The future is 8K.

Although 4K technology is a breakthrough, it is still not the limit. The limit of perception of the human eye is 8K. If the 4K becomes an 84-inch screen at a resolution of 3,840 x 2,160 pixels, the future 8K assumes a 145-inch screen (that is, its diagonal is 3.7 meters long), whose resolution is 7,680 × 4,320 pixels where each frame is equivalent to a 32 megapixel image of a camera.

A technology that already in 2012 the Telecommunication Standardization Sector (ITU-T), department of the International Telecommunication Union (ITU) dependent on the UN, approved the Super Hi-Vision 8K as a standard of the television industry . This body has been standardizing communications worldwide since 1865, giving approval to standards such as the protocol of fax machines, Internet Protocol (IP), JPEG images, ADSL and H-video coding standard. 264, among many others. That is, the future will be in 8K.
