At the same time HDR can also enhance the color gradient, so that the colors look more pure and bright. Raise reality, simulate light reflections, and make light and dark look natural. Below we will test the detail rendering ability through several static 4K images.
There are many factors that affect the effect of LCD, many consumers will pay attention to brightness, contrast, color gamut and other parameters, in fact, compared to these conventional values, the performance of the black market is actually more decisive, in other words, LCD backlight system in fact It is the culprit that destroys the picture quality of LCD.
