Now the whole world is discussing 8K, and 8K has become the mainstream of the display industry's future development. But today we don't mention 8K, and say 4K that was fired for a long time. Because so far, 4K seen by many people is likely to be fake 4K.
We all know that 4K refers to a resolution of 3840脳2160 or 4096脳2160, a signal with a width of less than 3840 cannot be called 4K, and a height of less than 2160 cannot be called 4K. The same 4K signal also has different differences, such as the frame frequency is 30Hz or 60Hz, the color space is YUV or RGB and so on, these will bring more obvious picture quality difference to the device with very good display effect.
For example, the maximum frame rate of the current HDMI 1.4 standard is 30 Hz, and the maximum value of this parameter for HDMI 2.0 is 60 Hz. The parameters of 60 frames are twice as high as those of 30 frames, and the quality and detail are better. The higher the number of frames, the smoother the picture is, and in the fast moving angle of view, the residual image of 60 frames is also less than 30 frames. The higher the value is, the higher the picture is. The closer you see the real world to the human eye.
For 4K screens, the difficulty of 60Hz is the large amount of data and high bandwidth. Compared with the common 1080P 60Hz point frequency is 148MHz, 4K 60Hz point frequency is reached 594MHz, which is more stringent for the signal transmission and processing requirements.
