1080p HD with sharpening and reality creation on auto.

Or did I fool you and are these the 1080p? Or the UHD?

I can not tell the difference anymore watching here and that surprises me. I think I am going to get that Oppo 103D with Darbee.

This is UHD

And one pick of the Marquee not any postprocessing or sharpening.

Screen shots are somewhat useless for this, their resolution is displayed here in less than 1920x1080, so the visual difference is hardly noticable.

Youd need to take the shots at much higher than 3840x2160 and post them as such for us to see what you see.

Netflix streaming is not exactly a fair comparison either.

[redfox001]

They show exactly the details that get lost when uhd material gets downscaled to hd and then displayed on a uhd screen with sharpening. They show that it is almost the same. I know that because I see it in reality. Do not forget that my iphone is very close to the screen to reveal what I see. The assumption that uhd material would look much better is simple wrong. With demo material you might see much more difference when you compare a remastered version to an old version.

Why is netflix material not the real thing? I think the demo material is useless. This is the uhd material you will be getting the most. Also it is worth a discussion if Baraka will suffer more loss in this process. I see no reason why. Baraka or the fifth element will look better in uhd and hd that is all.

Also click the shots to get the 8 mega pixel versions.

[redfox001]

Perhaps a movie like Baraka will reveal more difference we will have to wait till they apear on uhd. I will certainly buy an uhd player when they come available.

Also I do not know if this netflix material is true uhd with colour space and all. My sony ha a huge colour space but is it used? I read that my sony is not capable of rec2020 colourspace.

I will make some shots with 8 megapix to convince the hard believers. Oh wait just click the shots and see full resolution 8 mega pixel information. The iphone does make 8 mp shots.

I am reading that netflix uhd is not true rec2020. Also the bitrate is much lower than uhd blu ray. So perhaps a lot of detail will be lost in this material anyway.

I think the demo material is the highest bitrate available with shots revealing as much detail as possible preferable cartoons.

Think I can convlude that the extra pixels on uhd streamed material do not do much. When you clicl the above shots you see some difference but on 2 meter upscaled and sharpened looks like real uhd to me. And anothe fassinating conclusion is to me that CRT 1080p material looks like thes both too while old 1080p televisions look worse. So CRT does a nice job as a natural upscaler interpolating the pixels! What I did not show is that the picture on the Marquee looks much better than on the tv. I need better screenshots for that. It is more real, more life like.

I am reading that the first uhd blu rays will not be rec2020 either. Takes a few years again.

Since when has CRT done its own upscaling without the pressence of a LIMO PRO fitted to a Barco? Im not quite sure what youre getting at with the interpolation statement, CRTs display what is sent to them as a rule...

[redfox001]

Ha I knew some would not get that

I mean that when the beam goes from a black to a white pixel the electronics make that transition from black to grey to white. A CRT can not make real pixels and what results is an interpolated grey value in between. Now that is exactly what upscaling algorithms can do. If you have 4k pixels you have to think of a value for the pixels in between. I have to admit that perhaps a very smart reality creation algorithm can do a little bit more.

As for your other point that Netflix is not blu ray. Ok we wait and see what uhd blu ray material looks like in difference. From all the users experiences I read most people think that the difference is not so much in the bitrate but more in the way the movie is made. Some movies look fantastic on blu ray. A lot look bad even with high bitrates. Most do not see much difference between uhd and hd on present material.

[redfox001]

The current Moome supports 10bit and 12 bit deep colour. Could this be used for the HDR signal in UHD blu ray? Also Netflix is coming with HDR material soon. Anyone knows? I know that it is ment for digital displays with excess light but a CRT stack might benefit too? HDR is there because current displays can produce so much light that it becomes fun to distinguish between light and extra light to make it simple.

The difference between 1080p and UHD is clearly visible on large screens.

@ a home theater dealer.

With movie material (1080p) upscaled with a Sony VW520 and JVC X5000 and native 4K material on both of them.

Screen was a cinemascope in 4m width.

[redfox001]

Ok. 4m is big indeed.

I will really be convinced when I see the same uhd in 2060p and downscaled to 1080p and then sharpened to 2060p. Especially that last step is important for the question if uhd holds more sharpness or detail that we can not get otherwise.

[redfox001]

This might also be interesting.

The first UHD Blu-rays will probable use rec709 This is because they have to pay license costs for using rec2020 and there are practical no displays supporting it yet. The UHD Blu-ray spec allows for rec709. Likely it is not going to be rec2020 at all but p3 in the future.
