4K ultra-high definition television has become a popular and future trend with its 4x 1080p resolution, but users still encounter many questions when purchasing, such as the most common 4K problem. Today we talk about how to distinguish true and false 4K TV.
What is a 4K TV?
4K is an international standard for display technology. The screen resolution of a television must reach 3840×2160. The resolution of 4K is exactly 4 times that of a traditional 1080p full HD, so it is also called Ultra HD or UHD.
Although 4K only specifies the sharpness of the screen, it is obviously not enough if the television has only a screen with a resolution of 3840×2160. In order to ensure true 4K ultra high-definition visual enjoyment, the video content displayed on the screen must also reach the level of Ultra HD.
A look at the screen is really 4K
According to the saying, 4K is an international standard. If it can't reach the resolution of 3840×2160, it cannot be called true 4K. However, there is indeed an LCD screen that has been widely dismissed as a fake 4K screen in the industry. This kind of screen adopts WRGB technology, uses the neighbouring picture element and shares the sub-pixel way to reduce the cost, but this kind of screen has only 6 million picture element in total, and true 4K screen has more than 820 million picture element.
Since the difference between 6 million pixels and 8.2 million pixels can hardly be distinguished with the naked eye, this fake 4K is the most confusing. The only way is to pay attention to whether there is “WRGB†in the product description when choosing a TV. If so, you can determine that it is a fake 4K.
Note: Ultra HD certification does not have to fly
Many 4K TVs on the market will have an “Ultra High Definition Display Certification Specification†issued by an authoritative organization. However, many televisions adopting WRGB technology have also obtained this certification, so it is impossible to identify whether it is true 4K.
Second see if you can decode 4K video
TV has long been not a simple display. Connecting a mobile hard disk to play video has become an essential feature of all TVs. Of course, 4K TVs must also be able to play 4K videos. In the early days, many 4K TVs were defined as fake 4K due to lack of this function. The current model can basically play 4K video, but with the emergence of the H.265 format, new problems have arisen.
In the 1080p era, H.264 video encoding format is the mainstream, but after entering the 4K era, H.265 is the encoding format for 4K. According to technical data, H.265-encoded video files with the same resolution are only half of H.264, which brings convenience for network transmission or file storage. For example, as the music X50 Air support H.265 format, only 10M broadband can be smooth to watch ultra-high definition 4K video, if it is H.264 format, want to get the same clear picture quality requires a higher network bandwidth Caixing.
Currently, a few TVs that support the playback of 4K video in the H.265 format are still rare, such as LeTV X50 Air and Hisense LED50EC590UN. Although not satisfying this item is not a fake 4K, it will be very embarrassing after H.265 becomes mainstream in the future. So please consider as far as possible when purchasing.
Three to see if there is a 4K source
Of course, 4K TVs are used to watch 4K sources, otherwise the screens of Ultra HD are wasted, but the current situation of 4K TVs is very serious: there is not a 4K TV station in the world officially commercialized, and there is no 4K Blu-ray disc distribution. Internet downloads can only be downloaded to some 4K video clips or demos. The vast majority of 4K TVs don't have any real 4K source.
Fortunately, there are already some brands of TV sets that provide 4K movie and TV drama sources through online video. For example, TCL added a 4K area to the models that it collaborated with iQIYI and Mango TV, and there are dozens of 4K. the film. The 4K source is the most XTV Air launched by LeTV, and its 4K area has hundreds of 4K ultra-high-definition movies and TV series. The aircraft also participated in the Tmall Double 11 event, starting today in Tmall's LeTV TV flagship store booking double 11 spot, that can be purchased for 3979 yuan X50 Air host and three years of content service fee (original price of two years service fee) During this three-year service period, users can watch the 4K film and TV drama resources provided by X50 Air without restrictions.
