  hát, nem vagyok meggyőzve:

  "The key thing to understand is that broadcast TV, DVDs, HD-DVDs and BluRay are mastered with black at 16 and White at 235 (whether RGB or YCrCb representation are used - and Cr Cb are 16-240 centred around 127)."

  "In FULL mode the source - which is 16-235 - is remapped to 0-255 - so blacks which are encoded on the BluRay source at level 16, are not output at 16 and instead reduced to 0. Whites which are encoded on the BluRay source at level 235 are scaled to hit 255. Anything below 16 or above 235 (so called Blacker than Black and Whiter than White information) is clipped in FULL mode - it is NOT passed."

  "...if you send a display that is expecting the limited range (most televisions) the full 0-255 range, you will see a big increase in image contrast, but all of your shadow and highlight detail will become pure black and pure white. As you are overdriving the display (sending 255 when it is expecting to only receive 235) you may also see colour shifts with white objects. (they might be tinted red, for example)

  Many people perceive this as "better blacks" however the black level itself will not change. If you have a full black screen up it will look identical."
