TBH, I thoroughly enjoyed watching a movie on the EC9300. I've seen excessive NR in displays, and I did not see it here.
OLED TV technology isn’t exactly new—we tested the first set, Sony’s 11-inch XEL-1, back in 2008, and Samsung’s KN55SC9 set last year. (The Sony's black levels were so deep we had to buy new test equipment.)But LG’s latest OLED TV, the 55-inch 55EC9300 is notable for two reasons: One, it’s priced at just $3,500—about $5,500 less than last year’s models—and it’s the first OLED TV to make it into our TV Ratings. On certain key aspects of display performance, it was unparalleled. But unlike some other reviewers, we can't say that it's the best all-around TV we've ever tested.
The 55EC9300 is a visually attractive set, with a super-thin profile—thinner than even the sleekest LCD TV in our labs—and a gently curved 55-inch screen. OLED is an energy-efficient technology, and the LG model used less energy than any TV its size in our Ratings. Overall picture quality was excellent, and its sound was good but not great, which was not unexpected given the cabinet's shallow depth. The television's overall score placed it only fifth in its size category in our Ratings
Still, it's clear that in some ways the 55EC9300 has no rivals. This is especially true in the areas of black levels and contrast, which are deeper than anything produced by even the best plasmas. While it has a few flaws, it's certainly a harbinger of even better things to come, especially when the first OLED TVs with Ultra HD resolutions(3840x2160) arrive.
Black levels and contrast were superb with our test patterns and movie clips that often emphasize the performance limitations of LCD TVs, which use a separate backlight. For example, in scenes from the movie "Gravity," white objects—such as Sandra Bullock’s spacesuit, the spaceship, or stars—are brightly illuminated, while the deep black of space is, well, deep black, not gray like we see with most LCD TVs. Also, the depth of black did not vary with the viewing angle, another issue with LCD sets. The same was true with scenes from "Star Wars."
If you’re watching a football game, the OLED will look great, though it may not stand out from the better LCD TVs available. But if you switch to a dark scene in a movie such as "Batman" or "Harry Potter," the difference in black levels will jump out at you, delivering contrast unlike any other display. And there is no clouding or haziness, like we see with many LCD TVs. In our labs, every visitor was able to pick out the OLED TV from the LCD TVs in the room without a problem.
Many TV experts, including our own, feel that contrast—the difference between the darkest and brightest images a TV can reproduce—is among the most important elements of a TV’s picture quality. We have seen excellent black levels on some LCD sets, especially on those helped along by an effective local dimming feature. But while this feature can help improve contrast on darker scenes, it does little for brighter scenes, and can often introduce some unusual side effects, such as the unexpected illumination of areas that are supposed to be black. This is especially visible when the TV is viewed from off angles.) OLED is an emissive technology, meaning it produces its own light, so it doesn't need a separate backlight, and therefore doesn't need to resort to these tricks. Simply put, black levels and contrast are better on this set than any other TV we’ve ever tested, except perhaps the Samsung OLED set we had in our labs last year. (That TV never made it into our Ratings because it was rented from the manufacturer, not purchased at retail.)
Prueba OLED
Finalmente llegó a mis manos un OLED de LG. Es el modelo del año pasado, el 55EA9800. Estas son algunas de mis impresiones.
En primer lugar, en cuanto a la uniformidad la mala noticia es que no es muy buena. La buena noticia es que esto sólo es visible con los patrones de prueba. Yo no podía ver en absoluto con el material de programa normal.
En cuanto a color, con la gama establecida en BT709, el color realmente no necesita ninguna calibración. Una calibración LUT en esta pantalla sería una pérdida de tiempo. valores de DE en todo el espacio de color son alrededor de 1,0, con unos pocos valores atípicos de 2.
La escala de grises 20pt tampoco era necesario. El uso de la 2 puntos dado muy buenos resultados. Pellizqué 10% y el 30% un poco usando el Lumagen. Gamma es consistentemente en el rango de 02/02 a 02/03.
El LG reemplaza la pantalla de mi referencia personal, la novena generación de Pioneer Kuro. El LG es más nítida con los niveles de negro de calidad superior y una mejor profundidad. En su estado sin calibrar el color de la LG es un enorme paso hacia arriba desde el Pioneer, que requiere una calibración LUT para mirar realmente bueno.
Sure.
This is what I ended up with, calibrated by eye and am happy with;

White Balance. My display had what looked like a green bias, which on skin tones especially was not satisfactory. I found Warm 1 easier to dial in than Warm 2. Firstly I adjusted 2 point then refined with 20 point settings.
