It's also completely unusable on stuff shot on film as it misinterprets the film grain. I own both the UK version and the DE version of Dune (1984). Same transfer, same HDR grade but different encodes meaning slightly different grain fields.
Without DTM: Identical brightness throughout.
With DTM: Different brightness between the exact same scenes.

I would recommend turning it off.

The film grain has nothing to do with Dynamic Tone Mapping. All the function does is analyzes the picture and based on that either lowers or heightens the brightness/contrast. This is like Dolby Vision but without the metadata. Yes, it's not always accurate but it does a decent job at acting like Dolby Vision for 4K UHD Discs that just have HDR10 and not Dolby Vision.

You may have one of the processing functions on like Noise Reduction, MPEG Noise Reduction or Smooth Gradiation. That will do something with the grain fields. But I have never had issues with film grain when using Dynamic Tone Mapping on my LG C9. My set is also professionally calibrated so that might be a factor also.

I find this statement to be completely false.

If it's not accurate, it's doing the complete opposite of one of the things that Dolby Vision is supposed to do. Maintain artistic intent.

Have you even tried to compare any Dolby Vision content to HDR10 with Dynamic Tone Mapping set to "On"?? I've done this numerous times and have found it to be pretty dare close to what Dolby Vision does. I would encourage you to take a look.

I’m not saying it’s 100% Dolby Vision. It is just an attempt, like Sony and Panasonic TVs have their own DTM, to tone map HDR content that doesn’t contain Dolby Vision, like HDR10. It may not be prefect, but it’s something. If you are just watching HDR10 content without any dynamic tone mapping, then it’s just not going to look like what the director wants you to see.

Will be an interesting observation with reviewers chiming in their thoughts on 2022 OLEDs using QD & deleting the white sub pixel.

The durability of these panels remains to be seen but am sure a ton of R&D went into this during the Deuterium phase.

Welcome aboard Samsung. Let’s see your “No Burn in 10-year Promise” stickers on your OLEDs.

Signaling this could finally be a TV (by bringing back backlight master drive) to meet the standard the ZD9 did in all areas of PQ; and compete with the now evo OLED. Instead of just brightness alone, step-down local dimming and muddied specs using early implementation of things like xtreme wide angle in previous years of non-OLED Sony sets.

Been nearly a week owning the 77A80J. In terms of absolute picture quality for movies, the A80J easily wins over the ZD9 at least for HDR. Where the ZD9 shines is very bright high APL scenes. Sadly there are only few movies offering this and even then the scenes don't last for more than few seconds. No wonder many say contrast performance is key. I thought upgrade from 65 to 77 would be massive but it wasn't the case.

If I have the money and mood, I wouldn't mind trying a 85X95K provided it's done well and priced reasonably although I am a big fan of 'Z' series.

There he is! Normal service has been resumed.

Damn! The77A80J and the ZD9. Nice gear. Best of both worlds so to say.

QD OLED.. hmm let me guess. More colour saturation.

Not so much more color saturation, the samsung definition, but much less color washout in bright scenes that occur with current WRGB panels due to the white pixel.

[Geoff D]

It's called colour volume, just FYI.

Interesting, every year one can always rave about the TV with the best picture quality (note that the Bravia XR A95Kwill come in 65-inch and 55-inch sizes only) and assume therefore that carries over into being the best TV there is for one’s home; however, given the boundaries of the visual field of a human (over 100 degrees horizontally), unless you live alone (which sadly means you will likely die alone) and watch TV alone, a 65” TV is simply too small to achieve the immersive experience that serious videophiles strive for, especially those who rarely go out to a cinema anymore because the quality of their home setup is equivalent to, or exceeds the PQ of their local movie theater.

I just can’t see going smaller than a 70” TV for home entertainment with others. If one can not afford this year’s 83” A90J, I think the sweet spot for fulfilling the immersive viewing angle of the HVS and price point for those who live and watch TV with a family, or even just with one partner remains the 77” Sony A80J.
