Real 4K, pseudo 4K? BenQ BenQ take you to find out

'4K' as a kind of industry trend and application technology in the projection market is getting hotter and hotter. Various new terms emerge in an endless stream. Consumers often look at the flowers in fog and stand outside the threshold of 4K. It is difficult to distinguish between true and false. The controversy over nouns like ',' native 4K' is endless. So, what is the real 4K, 4K and 4K in the market? DLP projection brand BenQ BenQ takes you to find out.

Simply put, 'True 4K' refers to the 8.3 million pixels displayed on the projection screen (from Consumer Technology Association CTA: https://www.cta.tech/Consumer-Resources/Guides/4K-Ultra-HD.aspx Native 4K refers to the panel, 8.3 million pixels on the chip or mirror, and the corresponding projection screen also shows 8.3 million pixels. The pseudo 4K means that those screen display pixels do not reach 8.3 million pixels (generally 4.1 million pixels). ), but claimed to be 4K effect.

So, the real 4K needs the resolution on the screen to reach 4K effect, ie 3840*2160 or 4096*2160 pixels. The screen on the projection screen is presented by one pixel. The more pixels of the same size screen, the more The corresponding rendered picture is smoother and smoother. The 'native 4K' is just a technical means to achieve 'true 4K'. It is not a standard. Some 'real 4K' standards are implemented through native 4K panels, and some are implemented through other technologies. It is worth noting that What's really important in all 4K technologies is to show 4K performance in front of the audience. It is a 4K that can be clearly visible to the naked eye. It is a realistic and delicate picture quality effect, not an emphasis on what kind of technology to achieve. BenQ BenQ since 2016 In the 4K ultra-high definition home theater projector W11000, X12000 has been released since the year of 4K as the foundation of the company. It strives to provide consumers with a vivid and vivid experience.

More Modern True 4K Technology - Texas Instruments XPR Technology

4K has been occupying the high-end market since entering the projection field. The ordinary people cannot enjoy the ultra-high-definition picture quality brought by 4K technology because of its high price and huge size. But in 2017, Texas Instruments introduced a more modern one. The true 4K technology - XPR pixel shifting technology, can achieve true 4K 8.3 million pixels.

XPR technology can not only double the 2716 x 1528 (0.66 吋 DMD chip) pixels, but also achieve four times the resolution of 1920 x 1080 pixels (0.47 吋 DMD) to achieve true 4K 8.3 million pixels. (Of course there is little It should be noted that the higher the original resolution of the chip, the better the resolution of the final rendered picture is. Naturally, this technology uses DMD micromirrors to move diagonally or horizontally, vertically and horizontally, at a high frequency, allowing the screen to display 830 10,000 pixels, the final real 4K screen.

In the 4K TV market is so popular now, the popularity of home projector 4K is also a general trend. BenQ BenQ as the first consecutive sales of DLP projector 8 years (data from Futuresource) brand, in the implementation of 4K projection is also incumbent on the road , In December 2017, the 4K home theater projector, the Star W1700, was officially released in 10,000 yuan. It makes the body lighter and lighter, but also uses 9999 yuan in market pricing, opening up a 4K for the popularity of home projectors. The door makes it possible for ultra-high-definition quality to enter into millions of households. 4K home projection is no longer a 'luxury' that can't be seen from a distance, but it has become more close to the people.

It is worth noting that 4K is only a standard for resolution. In addition to resolution, projection technology has many other factors that need to be taken into account. Consumers should also be considered when purchasing products.

XPR Technology vs Native 4K Technology

It is undeniable that 'native 4K' is generally considered to be a relatively stable and clear image transmission method. Because its original panel is 4K resolution, the final image display is naturally more detailed and clear. The native 4K is of course good, but it is still difficult to understand. Millions of prices make it difficult to climb high, which determines that projectors of this class are difficult to access the homes of ordinary people. In addition to expensive movie projectors and high-end engineering machines, only a few brands produce 4K in the home area. machine.

Certainly some people will wonder, since XPR technology can achieve the same effect, then what is the difference between it and the original 4K?

First of all, in the actual viewing situation, the user is difficult to distinguish the difference with the naked eye. According to the actual detection of the BenQ Project Center, when viewing the true 4K and native 4K images brought by the DLP XPR at the same time, it is almost impossible to perceive the two in the image quality. The difference.

Second, the two technologies will produce a slight difference depending on the size of the projected picture. If you only cast one or two hundred inches, then there is almost no difference. However, if you zoom in to 300吋, 400吋, the picture performance will be slightly different. It is also why movie theater projectors generally use native 4K. A small hall in a movie theater can also accommodate one hundred and eighty people. Personal use, even in a mansion or Qianping Villa, may not be such a big screen.

For consumers, buying a 4K projector requires a 4K UHD (that is, 'real 4K'), and the CTA Consumer Association standard stipulates 'meeting a screen of 8.3 million pixels'. The others are 'pseudo 4K'. We do not deny the rationality and necessity of the existence of the original 4K, but we should embrace more advanced digital technologies because the advancement of digital technology will often bring about disruptive changes and allow more people to enjoy the high levels that once could not be enjoyed. Quality products. In addition to pseudo 4K Do not choose, what kind of 4K you will choose, depends on their wisdom.
