Lo de la Pana lo siento pero es así. Esa tele con los UHD tiene un problema. El problema es que en puntos concretos de algunas películas la
retroiluminacion se vuelve loca. Pero ahí no acaban los problemas porque en algunos paneos de cámara se ven las celdas del panel en la imagen. Por ejemplo en La Vida de Pi, al principio, cuando el tío de Pi está apunto de lanzarse a la piscina, hay un paneo y se pueden ver las celdas de la Panasonic en el pecho. Por esa razón la devolví la primera vez y por esa razón la he devuelto ahora, porque a mí, que lo que me interesa es el HDR, esos defectos se me hacen insoportables por muy buena que sea en otras facetas. Lo gracioso, es que a excepción de una REVIEW, que detectó este lamentable problema en Exodus y la penalizó duramente en la puntuación final, en el resto de REVIEW parece que no lo han detectado, imagino que por suerte y falta de tiempo para probar afondo estos aparatos, que un analista a lo mejor no la tiene durante mucho tiempo para evaluarla correctamente.
En fin, que para mí, si se va a ver UHD, que es uno de los principales alicientes que tiene esta TV, compra nada recomendable, aparte del abandono que ha sufrido porque ni la actualizan, que esa es otra
A John Archer no se la han pegado.
In the
Exodus sequence, where Moses meets Nun in the latter’s hut at night, you can clearly see a halo of light caused by the fact that even the honeycomb backlight system can’t deliver lighting localised enough to stop it from seeping into the surrounding darkness.
In fact, I can’t help but feel that the honeycomb design actually leads to the haloing effect appear far more exaggerated than it may with a less clearly "divided" backlight arrangement. This is because it creates extra, unwanted definition to the division between the light and dark areas.
The halos I’m talking about here typically extend for a good inch or so around any bright objects appearing against a dark backdrop. In fact, they’re so obvious at times that they make some sequences – including the aforementioned Chapter 7 of
Exodus – seriously uncomfortable to watch. So much so that if the TV had only the Low or (default) Medium setting for its adaptive backlight system then the overall mark attached to this review would read seven, not eight.
Fortunately, switching the adaptive backlight up to its maximum level greatly reduces the impact of the haloing during extreme contrast sequences. However, it doesn’t completely solve the problem, and it can also lead to some details being crushed out of dark areas – a price you just have to pay.
If you think that turning off the adaptive local dimming feature could solve the haloing problem, then you’d be right. But this option reduces the image’s black level response so much so that it’s hard to imagine many users feeling comfortable with it.
While the TX-65DX902’s problems with HDR are mostly restricted to dark scenes, I did also see slight signs of shadowy backlight bands during camera pans over very bright areas. There was also occasional momentary backlight instability in some shadowy and mid-colour tone areas, such as the shadiest areas of some of the pillars in the Pharoah’s palace in
Exodus.
On paper, the TX-65DX902 appears to be the HDR screen, but it fails to fully solve LCD’s inherent issues with delivering local light control in scenes where bright HDR objects appear against dark backgrounds.
