It turns out that a real 4K TV must meet these 4 points, did you know?

March 20,2023.

With the development of information technology, there are overwhelming 4K TV products on the market, many of which have some fake 4K products, so how to distinguish real 4K TVs? Today we will tell you that a real 4K TV needs to meet below 6 points

01
Whether the display is 4K UHD

First of all, we need to know the difference between 4K TV and ordinary TV. 4K TV generally has a resolution of 3840*2160 or 4096x2160, which is very different from the familiar 1080P in our impression, which is 1920*1080.

Remember: A signal whose width does not reach 3840 cannot be called 4K, and a signal whose height does not reach 2160 cannot be called 4K. Especially those TVs with relatively large screen sizes can basically feel more delicate and richer in details on 4K TVs, giving viewers a clear and real experience.

02
Whether equipped with HDMI2.0 interface

Since 4K sources have a huge amount of information compared with ordinary sources, this also puts forward new requirements for transmission.

Compared with HDMI 1.0, HDMI 2.0 and above versions can transmit 4K information sources more quickly, ensuring that users Fluency when watching 4K TV. If the TV doesn't have an HDMI 2.0 port, it's not even qualified to play 4K.

03
Whether it is a 4K decoding chip

4K TV must have 4K decoding. If there is no 4K decoding, it will look very blurry.

Therefore, 4K TVs generally have a built-in 4K decoding chip. When buying a TV, pay attention to whether the decoding chip is marked on the outside of the TV.

04
Whether to support H.265 video format

If the 4K TV does not support the H.265 video format, it is basically a fake 4K TV. When 4K TVs first came out, the built-in chips did not have the ability to play 4K video, or the decoding formats were incomplete.

Later, 4K technology became more and more mature, and the video format H.265 appeared, which can support 4K video playback. Therefore, whether it supports the playback of H.265 video format is also a way to measure the true and false 4K TV.

05
Is there HDR high dynamic contrast

HDR high dynamic contrast is a selling point of most 4K TVs. This function can make the contrast of the picture more intense.

The intuitive experience is that the color of the picture is richer, and most of the details in the picture are perfected to make the picture more real. Therefore, this selling point is still Very practical, you may wish to consider it when buying a 4K TV.

06
Whether there is "RGB" in the identification in the electrical specification

You can check whether it is "RGB" or "RGBW" printed on the logo in the TV specifications or on the outer packaging. Compared with the general RGB, RGBW will have one more color, which is white represented by W. The actual pixels of RGBW can only be It reaches 3/4 of 4K pixels, about 2880*2160, and the total number of pixels is about 6.22 million, which is 2 million less than the real 4K. This is not a real 4K TV, and the color will be lost.
