Comentarios que tratan de explicar PORQUE en una imágen contraste cualidad de la tecnología OLED, es importante tanto para contenidos SDR como HDR, mucho más claro niveles de negro que brillo en sí. También refrendado por Jhon (jrref)



Just want to take this opportunity to gloss over some boring, broadly related to C9 numbers regarding best case contrast ratio info using SDR brightness range of 0 black - 100 white as the base example for simplicity's sake.

If even a really good FALD set can achieve black levels of 0.05 for a contrast ratio of 4,000:1 - 60,000:1 ... OLED can achieve 0.0005, producing ludicrously higher contrast ratios in the same scene, which equates up to 6-stops of exposure difference.

Whereas each doubling of light output only accounts for 1-stop of exposure difference.

So although even the best alternative may get around twice as bright as OLED, that only accounts for 1-stop of difference in exposure per doubling of light (best case). Whereas the difference in black levels accounts for up to 6-stops (best case).

This is highly scene and content dependent and only reflects the potential of each set. For example, Arrival (2016) is intentionally graded quite dim and dull -- it lacks extreme contrast in SDR and HDR and will likely appear more similar between display technology than would something like IT (2017) or any number of the OLED store demo videos, which are produced to emphasize contrast in a way that many average real content scenes do not. Also, many video games and cheaper CGI in movies, especially older content, are rasterized in a simplistic way that leaves shadowy areas pitch black -- they don't even attempt to generate fill lighting or bounce (hence the worship of ray-tracing).

Just something to keep in mind when facing marketing hype around maximum nit numbers, because even concerning the relatively low full field white output of OLEDs, which range from 120 - 160nits in SDR, the contrast potential remains much greater. For HDR, that difference is multiplied further yet. Only when combating fairly high ambient light does extra light output begin to matter due to the perceived contrast ratio changing, given the way eyes adapt.

Sí, bueno, eso es algo que la gente no quiere aceptar. Se aferran a los nits en los LCD como algo "superior" pero olvidan que el negro base es ridículamente triste, aún usando trucos guarros (porque lo son) como el contraste dinámico y el uso de FALD en los modelos más punteros.

Lo peor del todo es leer comentarios de gente que de pronto te dice una cosa como más adelante la contraria, volviendo de nuevo a afirmar lo que antes no le valía...como algo válido. De locos.
 
Otra comparativa entre Qled 9 2019 y Oled en este caso E9 2019, no tan buena ni tan profunda como las de "Leoni", más bien es una preferencia personal.

Salud.

Tu que las ves con buenos ojos jajaja , gracias hombre :)


Yo lo he visto ahora amigo, antes no había podido verlo con voz y solo lo había pasado en imágenes aquí y allá.

Gracias por la mención que me haces en el vídeo, y recojo el guante. En cuanto pueda me acercaré a ver esas imponentes TVs, que ya sabes que de tiempo voy siempre jodidillo

Cuando quieras !!
 
Vaya, pues se moja con el tema tan candente de los mal llamados "macrobloques" que en realidad es otra cosa pero bueno, vamos a dejarlo así. Curioso que solo lo haya visto en Amazon Prime y no en el resto de fuentes.

En cualquier caso, creo que será el TV del año, en relación precio-prestaciones. Y seguirá vendiendose como churros.
 
Los problemas de macrobloques y flashes continúan siendo visibles en la generación 2019. Qué horror! Y eso que estamos ante una de las reviews por lo general más afines a ellos donde LG envía unidades inmaculadas que no tienen nada que ver con lo que los usuarios finales reciben en sus casas.

Por otra parte, Alpha no entiende de procedencias, por lo que le da igual que sea Amazon, Netflix o HBO. Simplemente mostrará macrobloques y flashes cuando se den las situaciones propicias para ello independientemente de donde venga el streaming. Estas tvs siempre han sido especialmente problemáticas con contenidos de regulera calidad.

A esperar a Panasonic...
 
Pues eso de TVs untadas, vamos que también tiene su sentido orientado no solo en LG, pero por ejemplo Vincent aclara y evita ello, tan igual como Rtings.
Pero porque no se comenta el tema interesante de Archer en C9.......HDR, si se cree a rajatabla lo de macrobloques:

I should pause here to stress that LG has achieved both these HDR improvements without substantially improving measurable peak brightness; I recorded peak light output on a 10% white HDR window of 820 nits in Standard mode. Which drops to around 780-790 nits in Cinema Home mode, and around 740-750 nits in Cinema home. All numbers which are pretty much in line with last year’s C8s.

Seeing is believing, however, and the higher brightness of small HDR peaks and higher average brightness levels with HDR content makes the OLED65C9’s HDR performance regularly (and literally!) feel like night and day compared with the C8s. Even though those 2018 models themselves greatly improved on LG’s previous HDR handling.

I should also add that we’re not talking about either peak or typical brightness levels on the OLED65C9 to rival those possible with the best LED TVs. In the context of OLED’s beautiful pixel by pixel light and color control, though, the impact of HDR on the OLED65C9 improved contrast is still dazzling. Especially in a fairly dark room.

Also important to note - though in this respect we’re not really talking about an improvement over the 2018 LG OLEDs - is the stability of the OLED65C9’s dark scenes. There are none of the subtle backlight adjustments, either localized or full screen, you get with even the best LCD TVs. Nor is there so much as a hint of the light blooming you get (especially during off axis viewing) with the vast majority of LCD TVs - even those with excellent local dimming.

Black level response has long been OLED’s star attraction, of course. So it’s not surprising to find the OLED65C9 consistently delivering incredibly inky, convincing black tones. Where the OLED65C9 does clearly improve on any previous LG OLED TV, though, is with its handling of near-black image content.
 
A ver qué ves. Y ojala te llegue perfecta, pero después de la review de Arche... :inaudito Creíamos que los problemas de la generación 2018 iban a desaparecer, pero ahí siguen según él.
Esperemos que LG con algún firmware ponga solución a este grave problema en la generación 2019.
 
A ver qué ves. Y ojala te llegue perfecta, pero después de la review de Arche... :inaudito Creíamos que los problemas de la generación 2018 iban a desaparecer, pero ahí siguen según él.

Lo que me ha dejado helado es que comenta que lo ha visto en una peli UHD.....se supone que con buen bitrate.....no es lo mismo que si lo ve en GOT por HBO.....
 
El problema NO SON los macrobloques. El BITRATE no tiene nada que ver. De nuevo volvemos a equivocarnos. No aprendemos. En fin, lo dejo.

En Interstellar, al principio en la habitación. Yo ahí tamb tenía en mi B8 q devolví macrobloques iluminados

Yo en la mía en pelis UHD lo noto un poco en el comienzo de infinitywars

Es una vergüenza de la marca LG .
Lo dije paginas atrás, los macro-bloques dirán su verdad.
Yo esperare como LEONI la E9.
 
Venga, que sí, que es una puta mierda. Sigue mostrando tu odio desde tu foro pero déjanos en paz en éste, ok?
 
Y como siempre, AVSFORUM siempre tiene respuesta técnica, sosegada y tranquila a todo esto:

A few facts:

older-generation WOLEDs likethe C6 only supported 60Hz refresh, did not support BFI, and had no issues with flashing/overshoot.

In 2018, LG introduced 120Hz refresh (only suppored through USB), introduced 50% BFI@60Hz, and late in the model year, the issue of flashing/overshoot was discovered.

LGDs development cycle for the 2019 WOLED panels was largely complete by the time the flashing/overshoot issue materialized (LGE needs final panel no later than mid--year to be ready with pre-production product prototypes by CES).

CES 2019 saw several impressive new features including 120Hz refresh now supported through HDMI2.1 as well as advanced 120Hz BFI (50%), different BFI levels @ 60Hz (25%, 50%, 75%), and 3.5ms MPRT. This capability was done, it was working, and it was even included in the review samples that were sent out just prior to release (was John Archer reporting on one of these review samples or final prouction FW?).

The FW 'fix' for the flashing/overshoot problem on the C8 was released around this time - after CES and before C9 launch and availability.

Also in this period after CES and before production release, we heard the first report from Germany that the 120Hz BFI features did not make it into the final product.

I believe the pre-production review samples were sent out after that report from Germany, so we were relieved to hear from first reviewers of the C9 review samples that the 120Hz BFI functionality was present (and appeared to perform splendidly).

Then when first C9 product samples reached early retailers like Value Electronics, we heard from jrref and others that the production FW no longer supported the 120Hz BFI features.

That's now been confirmed directly by LG and through other official 'launch' events like the one in the UK - 100/120Hz BFI features have been 'abandoned' on the 2019 WOLEDs.

And finally, we're seeing that in addition to the 2019 WOLEDs having identical BFI finctionality to the 2018 WOLEDs, the flashing/overshoot 'fix' that was released on the new C8 FW apparently addresses the flashing/overshoot problem in an identical manner to it's continued presence on the C9 (meaning the problem has been greatly reduced, but not eliminated).

Part of the flashing/overshoot 'fix' implemented in the new C8 FW appears to involve temporal ditherng, and using half of the 240Hz Effective Refresh Rate refresh cycles for temporal dithering to reduce the flashibg/overshoot problem means those same refresh cycles are not available for the insertion of black frames at 120Hz.

So the overwhelming liklihood of all of this is that the hardware cause of the flashing/overshoot problem exists on the 2019 WOLED panels identically to how it exists on the 2018 WOLED panels and LG learned of the problem too late to make any changes in hardware.

The FW 'fix' that was developed for the 2018 WOLEDs was the only option to reduce the underlying issue on the C9 prior to release (and to avoid a repeat of the embarassing 2018 uproar over this defect).

This FW 'fix' was finalized following completion of C9 development but before production release and the need to include it on the C9 production release (at the expense of 120Hz BFI) was made at the 11th hour to avoid an even larger launch fiasco.

The net-net of all this is that in the areas of BFI as well as flashing/overshoot, the C9 is identical to the C8 (and probably always will be).

If we see a repeat of these issues and limitations on the 2020 WOLEDs, it will mean it is something fundamental to the technology (or at least LGD's implementation of it).

If we see 120Hz BFI implemented on 2020 WOLEDs along with a complete elimination of the flashing/overshoot issue, it will mean LGD just needed a full WOLED panel product cycle (meaning at least 18 months prior to LGE product launch) to eliminate the issue in hardware.

The C9 appears to be a significant upgrade from the C8, especially in the area of near-black performance, but my guess is that anyone counting on ever getting 120Hz BFI on a C9 (or complete elimination of the flashing/overshoot issue) is probably in for dissapiintment...
