Of course, but at least with an HDR set you are watching "the HDR grading" correctly...

I will use this analogy: a Blu-ray 2D will look different from a Blu-ray 3D with 3D disabled on the remote....

Says who? All sets use diffrent tech and would have diffrent results.

You could capture the stream

Great, we are all waiting for you to post some.

There is that, yeah. I drone on and on and on about the SDR transform but the salient point is that the sets with HDR compatibility don't all conform to the base specs (1000 nits, 90% minimum of P3, 10-bit, IIRC), and what they're actually displaying is the HDR version 'tuned' to the particulars of that display via the reading of the metadata (static metadata it may be, at least it's something!) so it's not like every single HDR owner out there will experience the exact same "grading" anyway. In other words: this whole dealio is a crapshoot as to what it "should" look like, no matter what TV you have, and with the particulars of pro HDR calibration still up in the air maybe I really should Learn To Stop Worrying And Love UHD Blu-ray.

Hell, you're in a pretty good position with your Sony, mike. I know you're not sold on HDR but seeing as your set can kick out, what, 300-odd nits at maximum you're not seeing the HDR version in all of its retina-searing capability regardless, which might be a good halfway house in lieu of any other option. Me, I got 90% of P3, 466 nits at the last measurement and what appears to be a 10-bit capable panel, but the set can only recognise & process 100-nit SDR 709 signals. As Billy Cole said: Ain't life a b*tch?

The HDR stuff I have played on it just looks like some curry's employee has set it up

It's upside-down and on fire?

But imagine how much worse it would be if you had all them other nits!

May as well be

I don't have nits I have a special comb

Yeah, but at least the TV can "decode" the original HDR encode without needing an SDR conversion....

The problem with "capturing the stream" is: is there a PC HDMI capture card that does 10 bit/HDR?

I am interested in the encode not the colouring in personally

If he wants movies only with 4K DI he has a long wait.

There a quite a few...

Sorry, but those photos taken with a camera in front of the TV are nonsense and completely unreliable.

I really don't get your logic. If you play a DVD with VLC in Full Screen mode of course it is upscaled - unless you have only an SD monitor. A 1080p monitor or TV can only display 1080p resolution, everything else has to be scaled or it is not Full Screen but only a small picture with a lot of black on all four sides.

Upscaling a Blu-ray 1080p screenshot to UHD to compare it with a native 2160p screenshot is the same as comparing an NTSC DVD screenshot upscaled to 1080p with a Blu-ray 1080p screenshots.

Of course the Blu-ray is less sharp when you look at it in 4x magnification. But keep in mind that you are probably very close to your monitor when you sit at your computer. If you look at an Blu-ray screenshot upscaled to 2160p on a 1080p monitor it is the same as it would be to look at the same screenshot on an UHD display four times the size of your monitor at the same distance. No one would sit so close to it.

I also don't get the logic that the Blu-ray screenshot looks sharper if you scale it back down to 1080p. Of course it does, because it's smaller. If you would play a DVD on an UHD TV without upscaling it, it would be a tiny picture in the middle of the screen but it would look very sharp. That doesn't mean that resizing it to the screen's resolution would degrade the quality. It would just be bigger and therefore you could see the flaws in the picture.

Or look at the upscaled 1080p screenshot on your monitor, but from 15 feet away. Now it is not blurry anymore.

They were taken to show color and contrast differences shown on a 4K TV without HDR, not for resolution.

Upscaling a Blu-ray 1080p screenshot to UHD to compare it with a native 2160p screenshot is the same as comparing an NTSC DVD screenshot upscaled to 1080p with a Blu-ray 1080p screenshots.

UHD Kingsmen is from a 2K DI. There is no native 2160 resolution in the movie.

This one shows a pretty big difference. Much improved black levels which help detail pop and it's sharper too.

Could be from the high bit rate or could be another factor.

Even with the 2 2k upscales I've watched the difference In sharpness is obvious from 13 ft awag.

Yeah, better highs/lows. Maybe it's some of that HDR leaking through.

Hard to believe the picture would be so much improved just from bit rate.

Makes me want to get an HDR set, but I have to be patient and wait until next year.

heres a scene in the martian where i found the resolution increase to make a pretty big impact. The UHD version here is pretty obviously sharper. I also lowered the color down almost 10 points. IMO there really is no comparison, especially when your seeing this on a 65" tv and not just a computer screen.

by the way, anybody is more than welcome to share these pictures because these pictures are 100% indisputable that a UHD disc from a "2k DI" can have a great impact on PQ with resolution alone.

Which is which?

[ray0414]

heres another couple of pix.

1st pic is SDR with color at 55

2nd pic is HDR with color at 43 (lowered the color to simulate the SDR version closer)

3rd pic is HDR with color at 55

to me, its again obvious that the arm/leg and everything is sharper.

you might need to save them and put them side by side
