Screenshot Comparisons 4K

Having said that, I'm getting into UHD no matter what. Partly because I recently got rid of most of my blu-ray collection, for other reasons.

But I'm excited for the the format, actually.

Granted, these are just screenshots, but it almost looks like my theory has come true...HDR just looks like the movie is in the "Vivid" or "Dynamic" modes that purists have been deriding for all these years. I can show the exact same differences by switching "Dynamic Contrast" on and off. However, these picture modes do always introduce unwanted artifacts and graininess, so perhaps HDR accomplishes the same feat but without the nasty side effects. Just my two cents.

Honestly, every time I've seen HDR it's looked absolutely abhorrent.

Same, and have been watching more since I got a "HDR" capable TV

Any shot may have CG elements

About time more people are talking about it

I remember when 1080p was the shiznit lol.

Checked out the Kingsman UHD in SDR on a Sony 55x810c using default cinema pro picture settings.

Several scenes looked horribly overexposed. The parachute training sequence in particular did not look right at all.

I captured a few images directly from the standard BD version in which white detail can be seen in the clouds and sunrays -


In the UHD, those clouds and sunrays are absent detail replaced instead by blinding whites that obscure the picture. I really don't wanna take an ugly looking camera pic so to give a better idea of how it looks, the overexposure I saw in the Kingsman UHD looks very similar to the one in the old Leon BD - https://caps-a-holic.com/c.php?a=1&x...7&l=0&i=1&go=1

Is the HDR -> SDR downconversion causing the problem, I dunno? FWIW, I also viewed the Martian UHD in SDR and did not notice any brightness issues with that one.

Yeah, seems as if something's going wrong there with the SDR conversion. Have you tried changing the HDMI dynamic range from Limited to Full? It's separate from the 'Enhanced' setting which allows the 18 Gb/s throughput.

I have it on auto. I honestly had no idea that setting was for 18gbs throughput, I thought it was for RGB color format, or something I'll switch it to full and report back.

HDR seems to be a technical nightmare.... So confusing even for big time nerds on this forum... Imagine for an average user....

Just watched Hitman Agent 47 and had the same with the contrast being too high (SDR tv here) Using the players picture menu and changing the contrast down on the user setting helped a lot (the movie mode still too high contrast, the dynamic mode was laughably high)
Here's a couple of closeups of a closeup of the UHD and the Blu played on the samsung player.

The brighter one is the UHD (although it's not as bright when not amateurishly photographed; the headrest edges are clearly defined) and unless I screwed up something in my setup and not getting UHD even though the TV tells me I'm getting the right resolution, there appears to be no extra details here.

Maybe I can convince my wife the three dead pixels on the TV is grounds for an upgrade to a nice new HDR tv.

Basically it's that amount of bandwidth which allows the set to then accept the "High Quality HDMI formats", as it calls them. Without it any 4K 60p signal would be restricted to 8-bit 4:2:0 (though 4K 24p could still go up to 12-bit 4:2:2, as even HDMI 1.4 allowed that!!).

[vincentric]

I did not know high dynamic range did that, I thought it was the signal format setting that did the trick which I already have set to enhanced. In any case, changed high dynamic range from auto to full and, no change. Kingsman UHD is still overexposed like a mutha. Here's a quick and crappy camera pic -

Yep, same issue here with Kingsman. And good luck with the convincing.

[Geoff D]

That setting isn't to do with 'high dynamic range' specifically, just switching between PC/Full levels and Video/Limited levels, I know it gets very confusing with all these things called lots of different names by each manufacturer! Sorry it didn't help you none, I still think the HDR firmware update might be borked.

[JJ]

I think the interplay of the dozens of different possible displays with the one 4K player we have to date is quite fascinating.

Or, terrifying, if you can't get yours to work properly.

[Geoff D]

It's quite the cluster**** indeed.

[vincentric]

Haha, no worries, am actually having fun experimenting with all this crap even though it is all seemingly one big charlie foxtrot at the moment.

From that article:

"Even then, with three competing optional HDR standards, there’s no guarantee that the HDR decoder built into any given Ultra HD Premium set will be able to decode the HDR format on a specific Ultra HD Blu-ray disc. What a disaster!"


I thought that wasn't true (I asked in this forum!). I thougt you only need to make sure your tv and player agree on the same kind of HDR, and somehow they'll get to the HDR 10 information (except for Dolby Vision). Is this is so, I guess someone should point out the mistake in the article.
