IPS panels have a relatively moderate black value and this Sony also confirms that. With a native contrast value of barely 775: 1 it is difficult to make images with a lot of impact. Yet this Sony can, how? In the Cinema Pro mode 'Contrast optimization' is activated (in the lowest setting). Sony then uses a smart full-screen dimming and delivers an enormous improvement of the contrast to 2962: 1, a value that allows it to stand next to a lot of VA panels. The dimming effects are rarely visible, unless in extreme cases such as subtitles on an almost black scene. So leave that setting undisturbed, even if you think, 'I am not a fan of contrast'. The calibration of the device in this mode is excellent.
Esto que dice aquí es interesante, el contraste nativo es muy pobre 775, pero activando el global dimming sube hasta 2962, lo que como dice en la review es buen valor incluso para un panel VA, y este al ser IPS pues es estupendo, además dice que no se nota negativamente el efecto del global dimming, así que mejor dejarlo activado.
Parece que llega a los 600 nits, el año pasado eran 400.
