And today it's very hard to find curved screens in movie theaters anymore and I don't think many people miss them.

One of the questions the owners of 4K cameras are often asked is 'Why 4K when I don't have a 4K display?'. The answer is simple and related to your comment above. Taking an original 4K piece of footage and down-sampling it to 2K, results in a far better HD image which is partly the result of the increased color sampling that occurs in the down sampled video.

Put simply, it is highly unlikely that any consumer will buy an HD camcorder that will produce nearly as good results as a 4K camcorder down rez'd to 2K. Additionally, that 4K original footage can be archived for the time that the buyer actually does have a UHD TV. At that point it becomes a real piece of eye candy.

Plenty of information provided so that people can make up their own minds. I read nothing that would convince me that I should want to own a curved panel at any size. The slight advantages they provide under limited conditions, would not compensate for the cumbersome depth problems they will cause at the larger sizes.



I'd say curved TV's will do astounding well in the future. The quite distant future actually, when human beings evolve with an extra set of eyes at the sides of our craniums...

According to this article by Carlton Bale you'd have to sit three and a half feet away from a 55 inch set to see an improvement with 4K, and five and a half feet from an 84 inch set. This assumes 20/20 vision.

He's basing his calculations on the work of Bernard Lechner of RCA Laboratories.

http://s3.carltonbale.com/resolution_chart.html

I saw the 65" 4K from 7-9 feet away.

And anyway, non-controversial is probably the correct word.
All that chart ever did was confuse the crap out of people, and it in no way matches what I saw in person.

Lambda expressions are a horrible idea. Gentlemen: the goal isn't to make code readable for a competent mid-level engineer. The goal is to make code readable for a competent mid-level engineer exhausted and hopped up on caffeine at 3 am. What a disaster Java 8 is!

Out here the "super-premium" theatres still use them. But then, the screen is also 30' x 70'. At that extreme size, it actually makes some sense to bend the screen some. It really is a rather impressive experience, but I've been to plenty of movies on the flat screens and enjoyed them just as much even though they were on screens only 1/2 - 2/3 the size and not curved.

That's one point of view. But it does match what I saw.

And I don't see how the chart is confusing at all. You may not agree with the concepts, observations or facts upon which it was based, but it is hardly confusing.

Out here the "super-premium" auditoriums still have curved screens. Of course, those screens are also 30' x 70'. At that size, it makes sense to have a bit of a curve to the screen. It really is quite impressive. On the other hand, I've seen tons of movies one auditorium over on a completely flat screen that was only about 2/3 the size and it looked amazing. It seems no one around here is really bothered by the lack of curve, that's for sure.

Unfortunately, without ever seeing the benefits of curved screen, today's viewers don't know what they're missing.

That is so true. Recently they revived some Cinerama films, and Los Angeles is lucky enough to have prserved its curved screen (thank you preservationists) in the Cinerama Dome.

It's possible to feel more immersed with the peripheral information presented than with 3D.

But not on a 50-65 inch TV.

Given what we've been discussing on this forum, the following article is incredibly interesting and relevant. It discusses the presumed merits of both curved screens and 4K, based on the reviewer living with a 65 inch set for a month.

This flies against against extensive tests by renowned expert. So either your "normal" viewing distance is not generally recognized as normal or you have a guy named Bald Eagle in your genealogy .

Placebo is a wonderful thing. It's 4K therefore it must be better. Who cares about the charts.

In all seriousness, when you compare 4K and 2K TVs you're typically comparing panels that differ in other ways beyond just resolution. So it's never a valid comparison.

One would need to take the 4K TV and dynamically cut its resolution to 2K via pixel doubling and see if you notice the difference from typical seating distance. All the other settings would have to stay the same. Even that test has some margin for error since you're getting some extra inter-pixel spacing that would not be there on a 2K TV.

Not this again... A bunch of people who never tried 4K display properly make a comment about 4K. This is EXACTLY the same reaction when HD was first introduced nearly two decades ago. Thsi is EXACTLY the same reaction given by many LaserDisc owners when DVD was introduced about 15 years ago.

I've long appreciated your valuable, and knowledgeable input on this forum. That being said, the posted article was written by someone with real experience with displays, who lived with the 65 inch set for a month.

And in response to the previous poster, the writer did appreciate the excellent contrast, blacks, etc. of the Samsung, while at the same time commenting on what he felt were the other possible differences between 2K and 4K sets.

And lastly, I could see the difference between Laserdisc and DVD, immediately.

I'm looking forward to 4K, and will purchase when affordable, larger emissive display options become available.

Taichi4, thank you for the time to explain your view. However, although I do agree with virtually everything you mentioned, I find that resolution chart to be wrong and this is have also been confirmed by two of my clients. One is an optometrist and another is an opthalmology professor.

As my stance in purchasing 4K technology in general, quite honestly I'm rather disappointed. I'd rather the studios come out with HD markII (so to speak) with 16-bit, 4:4:4 colours as opposed to yet another 8 bit solution.

Hey, David.

When you have a chance, perhaps you could share what the two gentleman think about the resolution charts. I'm always eager for more information.

Did you read the posted article?

Cheers.

Curved TVS are dumb. But as long as there is AVS there will be the sales force here trying to sell whatever the industry is producing.

110-inch Flat 4K OLED...now that makes sense...how many years til the Chinese can produce that for 3K?

I still think though that a great deal of the allure that some have for this has to do with it being different. We're conditioned to become bored for evolutionary reasons, and when I sat in front of a curved Samsung tv for a while I did notice the "this is soothing because it's different" effect (to completely fabricate a term).

It's a well-established fact that a neuroscientist will say anything for a nice dinner and a 2008 Merlot.

Putting that aside for a moment, the article takes a narrow, myopic point of view. It may be true that curved objects make us happy, but they may simultaneously produce difficulty or frustration in certain contexts.
.
A curved tablet might make me happy, but it will not be as easy to carry around as a flat one, and I wouldn't like to try handwriting on it with a stylus.

A rose might make my girlfriend happy, but it won't substitute for a good breakfast.

Sure, and a curved tv might make you happy until you drop one on your foot. So what?

No. What's incredible is that someone would take a comment written in jest as a serious critique.

If I was serious I wouldn't have made a joke about it. I would have seriously criticized "scientists" for hire. I did not.

I do not believe anyone would sell out for a 2008 Merlot.

The very use of the expression "it's a well established fact" is obviously not meant seriously as it's an impossible, unprovable, and intentionally ludicrous statement.
