  De hogy maradjak ugyan annál az oldalnál és ne vegyelek igénybe Titeket...
  (Ez alapján fura, hogy mutathatott jól...)

  55F8000: Under this configuration, the black centre patch of an ANSI checkerboard test pattern measured 0.049 cd/m2. Interestingly, there is still some form of contrast or backlight processing going on, because the white window we had previously aligned to 115 cd/m2 (the closest [Backlight] setting to the 120 cd/m2 target – we could have gone brighter, but chose not to) now came in at 105 cd/m2 when placed on screen beside black patches. A totally black screen causes the F8000 to shut the LEDs out, but we can defeat the auto dimming by keeping a small amount of lit pixels on screen. In that scenario, blacks also came in at 0.05 cd/m2.

  50st60: The Viera TXP42ST60 also held onto its deep blacks, for the most part, during the ANSI checkerboard test. When white patches had to sit on screen simultaneously with black ones, the blacks only rose by 0.002 cd/m2, resulting in a reading of 0.007 cd/m2. Such a tiny rise is invisible to the human eye in the presence of brighter areas, anyway.

  Deep blacks are one part of the contrast equation, but it’s of limited use if the peak light output is curtailed: truly jaw-dropping video requires high contrast performance on both ends of the spectrum. The Panasonic ST60 delivers here too, with no shortage of brightness. We didn’t have any trouble getting 120 cd/m2 of peak luminance out of the 42ST60, and in fact could have pushed it higher, but at these giddy contrast heights, the picture was more than bright and deep enough.

  Peace
