Try setting your PS4 to limited and seeing if things look the same. Auto should be the way to go, but it seems your TV/PS4 is fucking up when it gets given the chance to decide for itself. Crushed blacks are always an indicator either the TV or PS4 or both are mismatching signals.
Can you confirm if you have your Samsung HDMI UHD Color to ON? I assume this is what the setting will be called on all Samsung TVs. This needs to be at ON for 4K signals, especially for proper RGB/HDR.
As per the post on the previous page its Enhanched HDMI on Bravia TVs
My post discovered on Samsung it seems to be HDMI UHD Color
edit: Just noticed you have said normal PS4. I assume HDMI UHD color may still need to be set to ON. I'm not sure how Sony do HDR on the normal PS4 given it's HDMI 1.4, but try this setting anyway.
We had some discussion in the KS8000 thread yesterday on this exact topic. Currently, we believe auto is possibly bugged for Samsung, as boot sequence can determine if auto = normal or auto = low... additionally, if one flips from auto to any other setting and back, it will 'snap' to limited.
So auto/auto with the Samsung typically results in low/limited RGB video at 8-bit RGB 2160p! So there is no mismatch, but...anyway, for now it may be easier and better advice to force the settings on the Samsung and PS4, which would be normal on TV and full on PS4.
When an HDR game is enabled, it should automatically go into limited YUV and the the video range will be "greyed out" indicating it is still functioning properly.
The PS4 Pro setting is ignored, if left at full, and only outputs limited anyway.
Correct, UHD color must be enabled.

My brain is boiling, I'm lost beyond salvation.
Could any of you tell me what setting I should use for a Samsung 65KS7000(which has HDR 10)? RGB or YUV420?

Auto RGB PS4
Auto RGB TV
TV HDMI UHD COLOR set to ON
TV set to GAME mode when using PS4.
This will work, yes, but...
Some Samsung TV are having a bug with auto in that it will cause RGB limited instead of RGB full when used with Pro. See my post above for more information.
If you are asking if 8-bit RGB or 10-bit YUV is better for SDR content, 8-bit RGB has a higher bandwidth over the HDMI, but I can see that both have advantages and disadvantage.

With HDMI black level on "auto" or "low" on TV and PS4 set to full, I get crushed blacks. This goes away if I set the HDMI black level on the TV to "normal".
In this case, what setting would you go for? RGB or YUV420 for games with HDR like Uncharted or Ratchet and Clank?
So if you have the PS4 Pro in full and the TV in auto, and restart the TV, the TV auto will now match full, I.e. Normal, but if you then change it, it will snap into low... it's a bad situation.
Games with HDR enabled on the Pro will never be in RGB, no matter your preset in PS4 settings, they will always be YUV422 or YUV420 (limited).
So really this question only applies to non-HDR games, at which point I am undecided, but I typically go RGB.

One notable exception seems to be The Witness which does require forcing YUV420 for HDR to avoid color banding, auto doesn't seem to work here.
It may be that the witness is outputting 12-bit 4:2:2 with auto, and some sets cannot handle the extra bits properly resulting in banding. I hope to test this out on my X800D on Sunday, I haven't had banding yet on a 4:2:2 12-but yet.

What should I be using for an LG B6?
I'd love to know too! And which hdmi slot
Kind of lost here.
The TV enables HDR bright mode automatically.
On the start screen of first light everything seems crushed no matter if I choose limited or full rgb (resolution set to automatic)

I cant wait to hear your thoughts, I bought the same tv after the Gaf thread and everything looks great except the dark scenes in the witness. The outside area on the island look stunning btw
Well damn, if you have the X800D and are seeing banding in dark regions that is a bummer. I'll do some testing for bit rates and such and report back on Sunday, but from what I am hearing, auto is resulting in banding, leading me to think it is outputting in 8-bit in HDR, which sucks and is not correct.
You have it right for auto.

Just go auto, your system will take care of everything. Some TV's do require you to check enhanced mode under HDMI Function, so perhaps without that your HDR functionality won't work, but if you have covered all the settings on your TV, then auto is just what you need to check on PS4.Pro....
In essence, you boot infamous, it will tell you that you have an HDR capable TV, do you want to switch to HDR etc...the same applies for TLOUR and pretty much all the pro patched games.
No doubt some sets will have issues dithering at 12-bit 422, which is what the Pro outputs by default for some TV's. 10-bit YUV420 should be used in this case.
If you read my post about The Witness, that HDR banding is occurring at seemingly all bit- depths and resolution combinations for me.

Does anyone know if x.v.colour has any place in the 4K HDR future?

I wonder if there is a way to fix this in the PS4's save mode...
Crystal ball shows a focus on Rec2020 for HDR content. Displays should start to get near 90% of it maybe next year...
So after much research and testing, I've found the following with my Sony X850C.
(This is set up through an Onkyo).
Automatic (for non HDR games):
4:4:4 8-bit RGB
Automatic for (most) HDR games:
4:2:2 8-bit YCBCR
I cannot get it to 10-bit YCBCR 4:2:2 for HDR, so have no choice but to force 4:2:0 to get 10-bit.
TV flickers (goes black for a short moment) presumably due to Onkyo switching, when changing between HDR and non-HDR.

i admit, i did not read all the posts, but as a one day owner of a 4k hdr capable tv (lg65c6) if i choose rgb the blacks are crushed in battlefield. just no detail in the shadows (argone forest). yuv on the other hand, you can see everything, same shadow, same area.
4k hdr yuv.

Whats your RBG setting? Full or Limited? maybe the corresponding TV setting isnt matching.
I have a 55 C6 and don't get black crush in RGB full.
Do you have the black level set to high on the TV?

Question: can I enjoy 10 bit colour depth on my hdr enabled tv but with standard range of brightness? With hdr pumping backlight at full level I lose black level and I don't like it.
It's the black level you need to be checking. I imagine the rtings settings would be set incorrectly for Pro RGB full.
I have the same tv, adjusting the black level gave an incorrect picture, in your tv settings try adjusting your gamma under advanced controls to low, this fixed the crush for me.

right. set it to rgb again, left it to full rgb and went and looked for this black level setting you speak of.
found it, it was on low, set it to high and even though the game looks a bit more washed out the crushed blacks are gone. just played a round on argonne forest and the sky was all white, but i dont think that was from the setting but from the fog and all that.
kinda in love with my blacks right now so every time i see grays or lighter darks i assume something is wrong. gotta learn to get used to the fact that if the settings are correct my eyes should get used to them.
le:
i effin knew it!
lle:
ok, i think i got it. rgb and rgb full on the pro. on the tv black level high AND gamma set to high 1 and no crushed blacks, no washed out blacks.
thx guys, cookies for all of you!
Yup those are the exact settings I'm running with too. I had gamma at medium for a while but I switched to High 1 and I think it's perfect.
The backlight should be adjusted in HDR so that the average picture level of your set in HDR = the average picture level of the set in SDR.
Obvious don't adjust this in an area with blinding sun, snow or sand, but someplace pretty neutral.
HDR and SDR should ideally look the same below 100 nits with the only exceptions being some very dark blacks that your set most likely cannot even display and some color saturations if the content supports wide color gamut, which most do not.
What TV and AVR? The resultant HDR output seems to be a function of the EDID, so if you are only getting 8-bit, force YUV420 at 10-bit it's much better.
SONY X850C and Onkyo 646.
I have been manually changing between RGB and YUV420, just a bit of a nuisance is all
I presume YUV 422 is no better than YUV 420 in regards to PS4 though?

Same here. But only with FF XV with HDR Enabled. The blue sky is a color banding fest!! damn

I got some braided silver ones off amazon they are slick
Link? No problems running 60?
This will eliminate the color banding in the Witness.

No thats not the case.
At 4K, non-HDR games 8-bit RGB can be best (not always) , HDR games you want 10-bit YUV420 as a rule of thumb. Or you can just choose limited 2160p YUV420 for everything and be done with it... unless you experience banding.
Why not check? Ratings uses auto which is fine for black level.
Because Game Mode doesn't allow auto black level on the C6

Yea no problems, works well with HDR and 4k60.
Here's the link for 10 foot:
https://www.amazon.com/dp/B01CRA11IU/?tag=neogaf0e-20
There's other lengths too.
The regular price was certainly not 25 dollars before so you're not actually getting 50% off, but I think it's a few bucks cheaper than when I bought it.
Actually just checked it's exactly the same price I paid for it, $12.99 for the 10 foot.
At 2160p, all HDR will be sent as YUV420 or YUV422, no matter what you try to force. The PS4 will switch signal resolutions without really telling you. Your set should be able to accept a 10-bit signal.
