Believe me, I understand your affinity to HDR (https://forum.blu-ray.com/showthread...ar#post9754213).

Hopefully, after being introduced into grading suites, eventually a home version of the Gargantuan - https://forum.blu-ray.com/showthread...d#post16674000 will become available when years from now, you’re feeling your Z9D has become long in the tooth.

As I think you’ll agree on this that one can’t have too much luminance display capability, at least to show highlights –

I'm sure one day the ZD9 is going to be looked upon like a wheezing old grandpa but it's crazy that a full three years after it came out there are still precious few consumer sets that can do ~1800 nits with such excellent blacks. Sony's new 8K can hit close to 4000 nits but the poorer backlight control is a major no-no for me. If I get the opportunity to willingly replace the ZD9 - that is, if it doesn't break down first and force the issue - then it's going to have to be a world-beater of a TV as I've been spoiled rotten with the ZD9, and I don't even have the best version of it!

@Penton-Man, we'll also have Sony's 77" A9G on the same wall for comparison with the three 8K TVs.

Without going on one of my Z9D fanboy rants again, I absolutely agree with you!

I wouldn't pay $30,000.00 for a TV if I was a multi-millionaire. That's outrageous!

Yes, the ZD9 has been in a class by itself in this way. A hell of a lot of value for what you pay to get this much mileage out of it.

[Geoff D]

And for all the talk about improved gradations on the 8K panels the 14-bit processing on the ZD9 is still incredibly effective i.e. I don't see banding unless it's there in the source.

And for some, the advantages to the 8K version, 7th down (VHF1-3)….https://www.idw.or.jp/award18.html

excellent, also would be good to learn the distance from the screen(s) to the viewing couch, etc. in your store in front of the 4K/8K set up

I missed that ^ upon first reading, sorry to learn. PeterTHX, I assume you still have unimpaired hearing, ergo f.y.i.- https://www.mixsoundforfilm.com/2019/home

...And if you can find an old Z9D (75" or 100" Class) to compare with.

I too have one in the place we keep down in SD, (in fact, I think I revealed that somewhere on this forum years ago when someone asked me about my device ownership), but my TV fanboyism is long over since my Qualia days.

Interesting.

I had never heard of this. But perhaps not entirely surprising, since I'm from Europe. Guess 005 and 006 would be something I would have like to have at the time...if only I could afford them then.

[Geoff D]

I'm from Europe, I've heard of Qualia but then I was selling these things at the time.

Wasn't this how SXRD came about?

You mean the 006 (as opposed to the 005 - TV: $14,999.99, with a SUXFQ005- Floor Stand $2999.99, SUXWQ005 - Wall Mount $799.99, SUXTQ005- Table Top Stand $499.99),

yes, the 006 was a precursor to the SXRD XBR2 –

[HeavyHitter]

I bought the final SXRD RPTV model (60" A3000) in 2007. I really wanted a 70", but they no longer made them.

I had a very active conversation with Joel Silver about some other advantages of 8K resolution and one item that Joel spoke about was that you can see at the normal viewing distance; how much better the higher resolution of an 8K display can reproduce curves and circles as it literally looks more detailed without jagged edges as a result of the smaller pixels and more dense pixel array.

I posted this video before, please take a look at the 8K panel discussion I participated in at CE Week.
https://youtu.be/fXIrE0rNnHo

Yet Robert, I read recently that a 4k UHD Blu-ray disc can actually look better, and be more faithful to how the cinematographer and director intended the movie to look, if that 4k disc is played on a high quality 4k display, rather than being played on an 8k display. And the reason for that is that the pixel grid presented by the signal from a 4k disc is an EXACT match for the pixel grid of a 4k TV, which gives you a situation that's just like overlaying an exact copy of an 8 x 10 photo right on top of the original 8 x 10 photo, with the match lining up so precisely, that each particular part of the picture on the copy is exactly directly on top of the corresponding part of the picture on the original photo.

But in the case of a 4k disc being played on an 8k TV, obviously the TV must perform scaling to make 4k information fill an 8k grid, and its likely that the result will not look as good, since obviously 4k resolution being manipulated to fit an 8k grid, simply can't be as precise of a match as playing a 4k signal on a TV that has a 4k grid.

And these claims that an 8k TV can significantly upconvert a 4k signal into something approaching 8k quality are pure BS, since extra resolution that never existed in the original signal on the 4k disc, simply can't be arbitrarily created, without changing the intended look that the cinematographer and the director actually had for their movie, when they did its photography.

Anyhow, long story short, though I can't remember exactly where I read it, an article I read last week warned folks not to be disappointed if they discover that the 4k material that they've been enjoying does not look as good on 8k TVs.

[Penton-Man]

scaling up to a non-integer factor would be problematic, traditional upscaling is pretty good, machine learning upscaling has the potential to be even better - https://arxiv.org/abs/1706.09077

Some 4K material is 2K native upscaled to 4K.

Which brings us to the question of a 2K DI UHD BD being so much better on a 8K displays versus a 4K display?

So Robert use Pacific Rim UHD BD for a comparison as one example. This title while HDR really shined the level of detail increase was more subtle.
