It’s interesting how the black levels suffer with any ambient light. Hopefully they’ll fix that with the next model (and have bigger sizes too).

So basically the a90j rebooted with a panel upgrade? Not bad. Still curious what it looks like against the S95B in filmmaker.

I really wish Sony would change how static-logo-detection works or allow us to disable it when necessary. There's no need to dim the entire picture when it's clearly a small element that is static.

Surprised to read that they watch a 55" from 3.5m away though

3.5m from 55 is way too far for a good 4K HDR experience.

I sit 8 - 8.5ft away from my 77A80J and 7ft away from 65ZD9.

I hope from 2023, Sony can push the QD-OLED panel and offer higher peak brightness on windows between 11 - 50%.

When will we see Samsung’s blue phosphorescent oled Tech?

[nick4Knight]

The blue phosphorescent is coming in 2-4 years. Its on the roadmap for many display makers.

DanBa, you still around? This news from last night - https://abc7.com/inglewood-world-cup...eles/11966381/
got my synapses firing with a Friday flashback from back in the day of a group of us having been fortunate enough to have watched up close and personal the Brazilian world cup team of ’94 practice at Cal State Fullerton, Roberto’s miss seen around the world – https://forum.blu-ray.com/showthread...e#post18921757
and now especially with the Filipina reporter’s line from abc7 news - ‘since the 90’s, camera technology has improved a lot’.

In that ^ regard, did you register for the myCANAL beta program for testing Dolby Vision 8.4 and how have you found it? There was a report to the developers from somebody watching the Champions League final last month with 8.4 that the HDR colors seemed washed out and I was wondering if you have been experiencing the same or if that was an anomalous situation with that particular live feed or perhaps the viewer’s TV. Granted, it is far, far more difficult to shoot and deliver HDR content for live linear workflows than it is for file-based post produced approaches, e.g. movies.

Merci beaucoup for the link, audio/commentary issue with Dolby Atmos aside, your comment “the incredible Dolby Vision picture quality” and this from Numerama is encouraging at to the picture quality outcome – “This is not the first time that a football match has been broadcast in HDR. beIN Sports had experimented with the technology for the 2018 World Cup. The rendering was disastrous, especially in terms of colorimetry (the lawn was fluorescent green…). So there was some apprehension. The doubts were quickly lifted: from the first seconds, we understood that we didn't want to go back.

The flow offered by Canal+ was close to perfection: dizzying sharpness (the details on the faces, etc.), wide shots of irreproachable sharpness, colors of bewildering accuracy, ideal fluidity, luminous peaks of stunning realism (the few flames during the opening ceremony with Camila Cabello). It's simple, we had never seen such a striking sporting spectacle, galvanized by the impression of literally being in the stadium.
It was enough to switch to the other streams to be convinced: the Full HD rendering was bland, when that in simple 4K UHD lost a little in naturalness. The gain in nuance is real with Dolby Vision, which guarantees a dynamic image that is all you need, by playing on the small details. It's really stunning and we would dream of seeing all the matches in these conditions..."

I think with the 8.4 variant, there has been substantial evolution for the good in Dolby Vision profile and potentially universal usage (beyond that involving only iPhone owners - https://www.youtube.com/watch?v=XmZMyLOXB28#t=10m33s and those exporting Dolby Vision videos from Compressor and Final Cut Pro) since 8.1 - https://forum.blu-ray.com/showthread...s#post15768174

Now only if somebody, someday would produce Le Tour in HDR - https://www.freewheelingfrance.com/t...022-route.html

BMD in action.

WEAK POINTS

Blooming still visible.
Limited native contrast (due to filter).

Contrast measured |2170:1
Black | 0.06 cd/m² |

Another site reported 7000:1 native Contrast.

2170:1 would be the contrast with local dimming OFF

I don't think any sane person would use this TV without local dimming anyway.

Yep and another site measured 7000:1 (native) probably using a different pattern with LD off.

The bad reviews seems to be more on the 65 and partly the 75. 85 seems to be liked by owners including ZD9 owners.

[Geoff D]

I doubt you'd get 7000:1 with local dimming off on even the bestest Sony LCD.

Yeah, my 2017 X90E without wide-angle filter was 5500:1 native and it was one of the best in that department. But its peak brightness was under OLED range so not a fair comparison.

7000:1 with LD off is impossibile

Look at the X95J figures:

Native: 2300:1
Local Dimming ON: 4050:1

Now with Mini-LED instead of standard LED they can reach 7000:1, quite an upgrade

I'm sure the Z9K will be even better

[lgans316]

I am only quoting what the publications say. 2 sites reporting different contrast ratios. That's it.

I believe Sony ZD9's native contrast with LD off was around 4500:1 and the 940e close to 5000:1 which I believe is the highest for a Sony LCD.

[Geoff D]

As the ZD9 is damned near 8000:1 (with local dimming ON, lol) already it's kinda depressing that Sony LCDs six years later are still only nibbling at its heels, even with the addition of miniLED for the backlight. But then that's the point: with great brightness comes great responsibility, it can be bright as fook but if the contrast is poor and/or the backlight control is hamstrung then it doesn't count for much.

Agree but it is all about the brightness and nothing else matters these days.

Probably because for people that prefer contrast to brightness there's OLED technology

LCDs are now used to push brightness because it's much easier than implementing a perfect local dimming algorithm (with good viewing angles on top of that)

If you want BOTH perfect contrast and super peak brightness, then you will have to wait for Micro-LED probably...

What this ^ means is that in addition to final distribution for home delivery in PQ with Dolby Vision – https://tech.ebu.ch/publications/pre...r_nbc_workflow



there is now another end solution available for streaming TV watchers, that of HLG vis-à-vis Dolby Profile 8.4 which is less critical for the need for consumers to control their ambient lighting in their family or living rooms. Given that advantage, should be interesting to see which workflow Fox Sports (Kevin C.) chooses for the 2022 FIFA World Cup starting this November.

[avs commenter]

what would be the magic contrast number that would make it almost indistinguishable from Oled? 10,000:1?

Given that HLG is a relative luminance system whereby the end display already has the responsibility of applying the OOTF, instead of PQ’s absolute assumption of OOTF, then what does the DV metadata that’s present in 8.4 do that the HLG rendering does not?
