RGB full/limit

What is RGB full range? In short, the TV set generally only supports 240 levels, from 16 ~ 255. The computer monitor supports 255 levels, from 0 ~ 255. RGB full range is enabled in the display option of the PS3, that is, 0 ~ is output to the TV ~ 255 of the full-color signal.

Do you want to open it? The answer is: If you want to enable the video, enabling the RGB full range will make the video more colorful. However, if you don't support the TV, the result will be counterproductive, the screen will lose a lot of black details

Why? The reason is very simple. Generally, the TV only supports 16 ~ 255, but most video formats are 0 ~ 255, so the PS3 will execute a very simple ing operation, put 0 ~ 255 of the values are converted to 16 ~ Within the range of 255. For example, 0 is changed to 16, 1 is changed to 17... and so on. But common sense tells us that 0 ~ 255 has 256 values, 16 ~ 255 only has 240 vacant seats. If it is converted to the past, there must be 16 empty seats. The 16 values must share one seat with the other 16. That is to say, you have lost 16 levels of detail. For example, if the 8-to-TV color order is 24 and the 9-to-TV color order is 24, then the two colors that can be distinguished by the full-color level are as follows, if you change to the TV color level, you cannot recognize it. This means that the details are lost, so the same picture is displayed, and the TV color level does not look full. Of course, this effect is not very obvious, because the loss of 16 levels is scattered throughout the entire 16 ~ In the range of 255.

However, if your TV does not support full-color order and you forcibly enable the full-color sequence, the picture will be more junk than not. With the full-color level enabled, the PS3 will output 0 ~ 255 signal, but the TV only recognizes 16 ~ 255 what should I do? In most cases ~ 15. The unrecognizable values are all processed as 16, which means you lose the details of the entire color gamut. If an image contains ~ If the TV's color level is changed, you can still recognize it. If the TV's color level is not supported, you can only see a whole black one.

If the monitor is connected, enable RGB full range, because computer monitors generally support 0 ~ 255 full color gamut.

If you don't turn it on, your screen may have a white effect, because the PS3 output TV Color Gamut starts from 16 and 16 is dark gray on the Full Color Gamut display, that is to say, the blackest color on the monitor is not black, but dark gray. The early firmware of xbox360 was connected to the monitor using VGA, and the screen was white. That's why.
