HDR Discussion Thread

[LordoftheRings]

And you're right Penton; streaming is becoming the mainstream and physical medium a useless expenditure to decor our walls and get mold on them over time. ...All that toxic plastic and rotten cardboards.

Thank-you that's interesting, although a huge step in the wrong direction IMHO. Consumers won't know that unless they max out those two things, the TV won't track PQ or tone-map correctly.
And it won't look as good.
And the "wow" factor won't be there.
etc.

Silly Samsung.

Good show! Again, congrats to the contributors…..https://forum.blu-ray.com/misc.php?d...osted&t=276605

I’m informed we tallied a tad over 1,000 views from 5 P.M PST to midnight PST, so for better precision we’ll innumerate it as -

1,381,041

"Standard" and "Movie" aren't "non-HDR modes". They are modes which auto-switch, and store two sets of values. They are effectively two modes of each, like Movie-SDR and Movie-HDR, but the TV does not tell you which it is in. It just calls both of them by the main name, eg "Movie".

To tell if the TV has switched to HDR, go to the Expert Settings and if it's switched to Backlight=20 Contrast=100 then it's in its HDR set of settings for that mode. You can, and should, set the other things to your taste (eg dynamic contrast, etc).

Also, if it's an HDMI input, the Info banner tells you if it's HDR - see picture below. So, use the remote to get to the Info banner. It's a single key-press on the proper remote with all the keys; buried in a sub-menu somewhere on the so-called "smart" remote.

But that only works for external sources: if it's USB or an internal app, you have to use the "look at the backlight number in Expert settings, and work it out" method.



On the Samsung TV end, colour space is a setting which selects between Native (panel native, auto (rec709 vs rec2020). So I will assume on the Oppo it's a setting to select which kind of chroma sub-sampling you want, if I were you I would leave it at 4:4:4, so that for movies it can use the 4K24 4:4:4 mode (plenty of HDMI bandwidth available at 24Hz, and lets the Oppo to the up-sampling).

Unfortunately on the TV end it refuses to tell you what bit-rate and chroma sub-sampling it's displaying.

This picture illustrates both these things:

I am not seeing that "banner" anywhere on my screen, even when it displays resolution and selected input...

But I should definitely leave the OPPO's Color Space to 4:4:4?

Created a new thread for the inquiry below before seeing this one. Figured it fit best here:

I some questions regarding the various HDR formats, and Dolby Vision in particular. I'll bring up the recent Avengers Infinity War release as an example to lead with. If one streams the movie on VUDU, one can watch it with Dolby Vision applied. Yet the word is that the physical disk copy will be HDR10, not DV.

My question then is who/what applies/decides the DV vs. HDR10 on a given video release? Does VUDU play a part in ensuring its version has DV applied? Or does the studio send them a separate master of the film that has DV applied already just for them? If not, is VUDU's application of DV potentially changing the studio's/director's intended look of the film? Forgive me if these are stupid questions, but I don't understand the process at all. Thanks.

So I'm pretty much ****ed with the TV I just bought?

"uniformity max elite". This sounds like something Samsung would pull. It's sad seeing so many people have to box up flagship tvs and play the return game due to banding and DSE. And it can't be good for profit/sales for these companies.


Some guy pushes you in the river, then he throws you a life jacket and wants you to thank him for saving your life.

But hey if they market and demo this correctly, people will buy it without realizing the above.

Thanks Ray & Robert!

I have to say that I've been very impressed with the uniformity of my 65ZD9 (my first one was a well-worn shop-floor unit and was awful, so that went straight back). Some faint vertical banding (which always gets worse if I have to move the TV) which I hear that direct LED backlighting can be prone to, but apart from that there are no darker blobs or patches with different colour temperatures, I loved my previous edge-lit Sony 4K set but the colour temperature went a bit squinky at the edges of the screen due to the backlighting.

Would lowering the backlighting setting reduce the flashlighting/blooming I'm experiencing? By default, this is cranked up almost to maximum...

You’re just playing SDR, MAXIMUM should only be used with HDR content.

The descriptors are different with each brand, but on my Sony my brightness is 15 for SDR and 100 (max) for HDR.

That’s Rich! As if 120 volts a.c. can’t find it’s way down the wires.

Btw, did you mean July in the accounting post?

You're talking about backlighting settings, not brightness, right?

No clue on The Samsung.

note to Geoff: regarding recent comments on another thread floating somewhere around the movies forums, even if the appearance of all the scenes is not the result of the principal photography, rather than so-called ‘DNR’ or defocus during finishing,

since the time of that ^ hyperlinked post in 2008, beauty work has become more refined with newer software like Mocha and Mocha Pro, e.g. - https://www.youtube.com/watch?v=3zCN1Wz9gJk#t=31m07s

Backlighting is backlighting, is it not?

Brightness is the black level control.

Were you referring to the panel's general overall brightness, as in the backlighting?
