PS4 PRO: for best IQ (Native 4k + HDR + 60 HZ + 4:4:4) 2160p-YUV420 or 2160p-RGB?

Everything on auto is a good idea. As far as your other questions, the HDR10 'standard' for UHD Blu-ray alliance specs YUV420 10-bit. As you know, these are games, not UHD blu-rays, and not all chroma subsampling from the Pro is in YUV 420, you will also see some YUV422. But you will not see 2160p RGB 4:4:4 (full) with HDR, as the bandwidth required is too high for the current HDMI 2.0a specification.

I agree people are having all kinds of incorrect settings. Most people should just leave everything in auto, unless they are having issues. And like you guessed, HDR shouldn't wash anything out. In an scene of average luminance, SDR and HDR should look identical. It isn't until you move into a high contrast scene, like some part of the image has very bright or the sun shining into it should you see a difference.

If PS4 Pro is in auto, for standard games it will output 2160p RGB 4:4:4 (full). In an HDR enabled game, it will automatically switch to limited, and then YUV420 or 422, with a bit depth greater than 10-bits (unless your set has an EDID issue with the Pro).

Thanks, that makes a lot more sense. I fired up UC4 chapter 8 which starts in Scotland outside, so yeah, bright area with snow reflecting light. It doesn't look washed out on auto with HDR on/off, just some lighting changes, which are expected between normal and HDR mode, even on my TV set which has pretty low-end HDR. However as I said if I force the TV to full, and the PS4 Pro to full, it appears washed out when UC4 turns on HDR. I assume this is some sort of inverse of crushed blacks, where blacks still aren't reporting correctly and the on-screen image appears incorrectly.

I decided to unplug my Nvidia Shield TV from my audio receiver and plug it directly into my TV. Most content I view on it just has DD 5.1 or DTS 5.1 so my TVs ARC can supply that to the sound system. The Shield TV supports HDR as well which I hadn't noticed, and until I get an HDR passthrough audio receiver it's wasting some of these devices potentials. I've put the Shield TV on auto now as well, as I was running it on full RGB in it's settings, and on the TV HDMI settings. Probably should have had it like this from the start considering I watch movies and TV shows on the shield, not play games. Tbh I've set ALL HDMI inputs on the TV to auto now. I'll just let it do it's own thing depending on the signal sent through the HDMI cable from whatever source I'm using.

I see where the confusion is now.

Here is the thing: it is literally impossible to force the PS4 to 'full' during HDR gameplay. It ignores whatever setting you have. The TV, which you can force to full, is then creating am video range mismatch.

You can test this yourself. Flip back and forth between RGB video range with a non-HDR game (or no game) playing. You will see the TV turn blank for a moment while it changes settings. Then fire up an HDR game. go back to the Pro settings and flip back and forth... you will see there is no delay at all, as no setting is being changed.

Ideally, theyy should have greyed this out while HDR is enabled as there is literally no change (because it only outputs limited).

Yeah I think a big problem was my TV setting more than anything. HDMI settings on the TV for my 4 HDMI outputs with RGB are

Automatic
Full
Limited

I was forcing all TV HDMI settings to FULL. So even if the PS4 can get its settings to change as needed having my TV always want to accept a signal as full would presumably be causing a mismatch when the source wants to transmit as limited. In reality the TV settings should probably always be auto and then whatever source you are connecting can switch as it needs, or be forced as needed.

The more I think about it the more I wonder why the TV (Bravia) even lets you force the HDMI inputs. Unless it's just there for an additional option and the rare cases of compatibility issues. As I said putting it to auto should mean the source can make its own mind up. At least that is what auto suggests and how things now seem to be working with the PS4 pro.

Such is the wonderful world of various HDMI standards, 4K/HDR standards and devices and TVs all supporting different things...

In one sense its good in case there is a compatibility issue, you can 'fix' it yourself, but on the other hand, it if there is confusion, it will cause a mismatch when set improperly.

My Sony allows the user to switch as well. IIRC, the Samsung KS8000 'greys' out this option during HDR mode...

I take it you just set yours on auto as well? Ah well the more you know. I'm always learning more about the world of TVs. I'm sure when I buy my next set we'll be on HDMI 3.0 or something :p

Yes, I do leave it at auto, it works perfectly with the Pro.

What is your exact model number? Sony typically requires either HDMI inputs 2 or 3 with Enhanced HDMI signal format (4K/60 Hz). HDMI 1 may not offer full support.

I've set all inputs to Enhanced HDMI. 1 and 2 are the Pro and Shield TV. 3 has nothing. 4 is ARC which goes to my 4K receiver (no HDR on this, just 4k passthrough). Connected to it is the Xbox One/Wii U and PS3.

There was nothing to suggest HDMI 1 couldn't do everything okay. It has the enhanced option and my PS4 pro reports back fine

Sounds like your set supports all HDMI inputs. Looks good.
 
Probably been answered but my friend has a similar Sony TV (850C), its HDR Compatible, not Capable. What does that mean for him exactly? That it supports the input but doesn't output an actual HDR image right?

What should he choose based on that, Auto/RGB or YUV420?

Same model as mine if so. It does HDR but it's an edge lit panel so can't really do HDR "properly". You can still benefit but it's the lowest end HDR you'll get. The good sets will do local dimming I think it's called.

I'm not sure where you or him have plucked the compatible and capable words from. It simply supports and outputs an HDR image, it's just not going to be on the level of more modern or expensive HDR set. This range is 2015 Sony, and at that it was mid-range when it launched.

As I've found out tell him to put everything on auto. The PS4 will jump between the required settings for HDR and normal gaming.

for YUV 'anything' that this set will put out, then its going to be limited.

Honestly, i think enough GAFers have confirmed both the X800D and the KS8000 can be set to all auto without any issues.

If you chose all auto on the pro, it will default to the highest bit rate capable for a given output.

I just want to confirm so I am 100% sure, If I am auto or 4K RGB, SDR content will be 4:4:4, correct?

Xbox 1 s. Is 8 bit used for 4k hdr or 10 bit. It auto set to 8 bit color depth. Is this correct?

Is the KS8000 automatically switching to Limited, during HDR content, when the option is grayed out? Should I manually change it to Limited before switching the PS4 to YUV?

Is there any point going RGB + Full, or should I leave it on YUV420 + Limited all the time? I heard RGB + Full will yield slightly better image quality. I sit close to the TV, so anything helps.

I suppose I can go full auto on everything, if people are indicating it works. I have trouble trusting it though.

Auto on PS4 will give 2160p 8-bit 4:4:4 (full) for non-HDR enabled game.

I responded in other thread. For SDR, its kind of a non-issue, but ten bit is fine. It may give a slightly better response in dark areas of the image.

Yes, it is automatically switched to 'limited'. Full RGB at 8-bit vs. YUV420, I think each one will have an application where it may produce the better result. For now, I think it is a bit of a wash, but for certain, 8-bit RGB 4:4:4 is much higher bandwidth over the HDMI cable than the 10-bit YUV420.

I sit very close to the TV as well, ~ 2 feet from a 43", so I usually set all to auto, and get 2160p 8-bit RGB 4:4:4 for SDR.

Auto is working properly on the X800D, and from various reports in this thread, it appears to be working properly on the KS8000.

I am getting bad color banding in The Witness. Has not been an issue in Deus Ex or Uncharted.

I have all my PS4 Pro video options set to auto - which seems to default it to RGB for non HDR mode and YUV422 for HDR.

Manually forcing YUV420 seems to reduce but not eliminate banding.

Turning off HDR eliminates banding.

I see lots of posts about these banding issues - what's the best solution?

Thanks. I changed everything to auto and it seems to work other than using YUV422 rather than YUV420 for HDR content, at least with Uncharted 4. I manually changed it to YUV420 and don't think I noticed any difference, but only compared for about a minute or so.
 
OK you have an Xbox S?

So you just leave it on 10 bit? I didn't see an auto. I can't imagine we need to keep changing it for SDR content.
There is no Auto. Really, you should match the Xbox One S to your HDTV. If I remember from your posting, you have a newer UHDTV. Some owners of last year's models, and some this year, are only 8-bit panels.

The idea here is you don't want your TV do any processing it doesn't have to.

OK. Yeah I have a 10 bit panel. I played forza last night and it looked great but nothing like the ps stuff. I'll try 10 bit and see if it looks any better now.

Its true some games output YUV422 and YUV420, and users have reported everything from 8-10-12 bit depths with an HDR enabled game.

I don't have The Witness, although I plan to pick it up Black Friday.

Do you have an AVR in the chain? What is the exact model number of your TV?

There should be little difference between the two. YUV422 has less chroma subsampling and ideally should produce a better image. The other player in the game is bit depth, and that can be difficult to identify without an AVR.

Thanks, man. JS9100. No AVR involved at all.

What confuses me most is why The Witness is affected but not other HDR games I've tested. Do different games output different bit depths, without disclosing it? I don't even fully understand what produces the banding in this game, so I have no idea where to begin trying to address it.

Does the TV have an auto setting instead of normal? If so change to auto, also put the PS4 rgb range to auto.

I used to run full on TV and full on PS4 but it causes issues now that I have a pro when a game uses HDR. HDR mode in games as I've been educated in here wants to run in limited so forcing the PS4 and TV to expect full will cause issues.

HDMI black at normal is probably limited as well by the way, so right now you technically have a mismatch with the TV on limited and PS4 on full. Although someone can correct me if I'm wrong for that set. As I said normal just suggests limited to me. My bravia actually states full, limited and auto so it is much clearer than stating "normal" and whatever other options you have.

Got it! Will set both an automatic when I get home in that case. Actually now that I think about it, I'm almost certain the TV (ks8000) doesn't have an auto setting for HDMI Black.... only normal or low.

In the case that I do not have an auto setting, would it be better to set the tv and ps4 pro to limited?

I remember there was an issue with setting the PS4 to automatic before as it didn't read the TV settings correctly before. Wasn't sure if this was still an issue.

Thank you so much for your reply. I'm sure this stuff gets redundant around here, but I just wanted to be certain.

Especially after reading that HDR games need to be set to limited on the PS4 and the TV. If the ks8000 has an auto setting, that's perfect.

I was just afraid of setting the TV to full, and the PS4 to auto because it could potentially mismatch the settings on both :p

While that works as it is the equivalent of what I ran my PS4/TV at the issue came when I tried to use HDR. Even if your TV supports full from what I've discovered it needs to be able to switch over to limited for HDR. Unless your TV has the ability to know this where mine doesn't then you'll end up with a mismatch. For me it made HDR look washed out.

Auto just seems the best way to go. When I do that normal gaming still plays in RGB full and only when I turn on HDR does it switch to limited.

This is exactly what I was wondering in my post above. It seems like you should either set both to limited or both to Auto (for HDR capable TV sets). If you switch both to full, when an HDR game kicks in you will get a bad picture.

Seems like the ks8000 is smart enough to run automatic and switch between these settings appropriately.

Which TV do you have if you don't mind.

Just wanted to post an update.

Changed the setting on my KS8000 for HDMI Black Level to Auto, and did the same for the PS4 Pro. Seems to work flawlessly, so I am happy with that.

I did notice however that the PS4, even when set to auto seems to default to Limited RGB Range and not Full... even though my TV is fully capable to running Full.

Not sure why that is... but I am now wondering if there is any benefit to running Full vs Limited? Wouldn't there be a better range of colors, blacks, brightness....etc with a range set to full?

Either way, going to leave them both an auto... it does what it's supposed to.

How did you test this? When on the PS4 OS menu did you change to full and the screen flickered? If it's in full it shouldn't do anything when changing from auto to full, but flicker if you select limited.

If the screen is flickering when changing to full are you in GAME mode on the TV? I run in GAME mode with the PS4 to reduce input lag. I wonder if me running in this means it defaults to full as games are created using "full RGB".

Your other settings can effect this as well, such as if you are forcing YUV420. Then, you will always get limited.

If EVERYTHING in video output settings is set to Pro, then PS4 Pro should normally output 2160p RGB 4:4:4 (full) when playing an non-HDR game. when playing an HDR enabled game, it will auto switch to limited YUV422 or YUV420.

The Pro will attempt to output the highest bandwidth signal possible for the given content.

in terms of BW, and not necessarily image quality:

RGB 8-bit >YUV422 10-bit >YUV420 10-bit

Do different games output different bit depths, without disclosing it? I don't even fully understand what produces the banding in this game, so I have no idea where to begin trying to address it.

Yes, currently different games + TV combinations are resulting in different outputs. For HDR enabled content (games) users are reporting: YUV422 8, 10, 12-bit and YUV420 8, 10 , 12-bit.

So its a bit of a wild west currently, but it is likely that it is the EDID (smart HDMI handshake) that occurs between the Pro and your set, and then the Pro decides how much chroma subsampling and bit depth your set can handle. It seems as if it errs on the optimistic side, which is great if your set can handle it, not so great if it can't.

Color banding can occur if you are receiving 8-bit 'HDR', or 12-bit and your set cannot properly dither the extra 2 bits... You may also be seeing luminance banding, I am just not sure. I hope to pick this game up on Friday flash sale, so maybe we can compare notes with some screenshots to see if we can get the banding worked out, or at least whats causing it.

I've set all inputs to Enhanced HDMI. 1 and 2 are the Pro and Shield TV. 3 has nothing. 4 is ARC which goes to my 4K receiver (no HDR on this, just 4k passthrough). Connected to it is the Xbox One/Wii U and PS3.

There was nothing to suggest HDMI 1 couldn't do everything okay. It has the enhanced option and my PS4 pro reports back fine

The way I tested it was by setting the PS4 Pro to Automatic (the tv as well), when I would switch to limited the screen would not flicker. When I switched to Full the screen would then go black for a second. This is how I know that the PS4 defaults to limited if it is set to auto.

Yes I am in game-mode with my tv settings, also have hdmi black level set to auto. Hopefully is does what it is supposed to...

Your other settings can effect this as well, such as if you are forcing YUV420. Then, you will always get limited.

If EVERYTHING in video output settings is set to Pro, then PS4 Pro should normally output 2160p RGB 4:4:4 (full) when playing an non-HDR game. when playing an HDR enabled game, it will auto switch to limited YUV422 or YUV420.

The Pro will attempt to output the highest bandwidth signal possible for the given content.

in terms of BW, and not necessarily image quality:

RGB 8-bit >YUV422 10-bit >YUV420 10-bit

I have every setting set to automatic, I will test this with a non HDR game and see if the ps4/tv set it to full.

It is required for 4K/60Hz.

Enhanced HDMI Signal Format in settings:
SETTINGS > EXTERNAL INPUTS > HDMI SIGNAL FORMAT > ENHANCED

Realize as well, not all HDMI input may support this feature.

Oh, I see. Thanks!

Will test it tonight.

Same model as mine if so. It does HDR but it's an edge lit panel so can't really do HDR "properly". You can still benefit but it's the lowest end HDR you'll get. The good sets will do local dimming I think it's called.

I'm not sure where you or him have plucked the compatible and capable words from. It simply supports and outputs an HDR image, it's just not going to be on the level of more modern or expensive HDR set. This range is 2015 Sony, and at that it was mid-range when it launched.

As I've found out tell him to put everything on auto. The PS4 will jump between the required settings for HDR and normal gaming.

Just to note, only the 55'' is edge lit on the X850C, the 65'' and 75'' have local dimming.

I have the same model but I didn't get RGB, just YUV420. Sorry for my ignorance, but what is this Enhanced HDMI? How do I set this?

Yeah as III-V has said. He is hauling ass to educate in here lol. All the HDMI inputs on our set support this setting, so we're all good.

If you don't turn on enhanced HDMI then 4K won't work in RGB.

The way I tested it was by setting the PS4 Pro to Automatic (the tv as well), when I would switch to limited the screen would not flicker. When I switched to Full the screen would then go black for a second. This is how I know that the PS4 defaults to limited if it is set to auto.

Hmm, yeah, your TV/PS4 is defaulting to limited. What model is it if you don't mind me asking?

As I said to the poster above check if you have some sort of enhanced HDMI setting. PS4 defaults to a 4K resolution on a 4K TV (on OS menu and in-game, it upscales) so for RGB support on some sets like mine enhanced HDMI needs to be turned on.

Just to note, only the 55'' is edge lit on the X850C, the 65'' and 75'' have local dimming.

Really? That's good for those models. Must just be the 55" is viewed as the cheaper/entry model for this line. They are all 2015 sets so HDR isn't going to be anywhere near as good as it is on newer sets. Local dimming is a must though, so likes of this set being edge lit HDR takes a further hit into mediocrity.

I stress that for anyone buying late 2015 set/2016 set. Make sure you can get local dimming within your budget. Optimally go OLED, but they are still rather expensive. My next TV will be OLED in a year or two.

Yeah I think a big problem was my TV setting more than anything. HDMI settings on the TV for my 4 HDMI outputs with RGB are

Automatic
Full
Limited

I was forcing all TV HDMI settings to FULL. So even if the PS4 can get its settings to change as needed having my TV always want to accept a signal as full would presumably be causing a mismatch when the source wants to transmit as limited. In reality the TV settings should probably always be auto and then whatever source you are connecting can switch as it needs, or be forced as needed.

The more I think about it the more I wonder why the TV (Bravia) even lets you force the HDMI inputs. Unless it's just there for an additional option and the rare cases of compatibility issues. As I said putting it to auto should mean the source can make its own mind up. At least that is what auto suggests and how things now seem to be working with the PS4 pro.

Such is the wonderful world of various HDMI standards, 4K/HDR standards and devices and TVs all supporting different things...

I too was forcing all to full and thought everything was ok. While HDR content looked very good, it wasn't a true wow effect or anything. I figured it's because my TV (sony xd85 = x850d) apparently doesn't have the best implementation of HDR, or so rtings.com said.

But then I switched the input settings to auto both on TV and PS4, and WOW. The difference is quite remarkable, at least in Ratchet & Clank. So thanks a lot for the info!

Thank the poster III-V, I came in here asking why my HDR looked crummy in UC4 and he educated me :p

I currently have HDMI Black Level on the TV set to Auto, and RGB Range on the PS4 Pro set to Auto as well.

I'll have a look online but I'm going to guess even a Samsung set will have some sort of "enhanced HDMI" setting. It's my understanding such a setting exists to prevent non-4K source equipment having any compatibility problems.

So "standard HDMI" would be used if you just had a 1080p device, "enhanced HDMI" for 4K.

You need to turn HDMI UHD Color to ON.

An HDMI connection with HDMI UHD Color set to Off supports up to UHD 50P/60P 4:2:0 input signals, while an HDMI connection with HDMI UHD Color set to On supports up to UHD 50P/60P 4:4:4 and 4:2:2 input signals.

4K at RGB full is 4:4:4 IIRC. If your HDMI UHD Color setting is at off then it cannot run 4K at RGB full correctly, hence, is defaulting to limited.

I appreciate your help spreading the word it's a full time job keeping up with a this thread.

Also wishing OP could issue an update so people don't even have to post confused.

Either that or maybe we should start a new thread with all FAQ answered.

Well thanks to you :) Really is hard to keep up with all the info, but I think now I've settled with the "perfect" settings with my tv, with both HDR and non-HDR content.

Is it confirmed that auto is the way to go?

I have a Samsung JS8500 and a standard PS4 - previously I had the console and tv rgb both set to auto. When I tried HDR for the first time I noticed that blacks were crushed and I could barely see a thing.

So I went ahead and changed the PS4 to "full" and the tv's hdmi black level from auto to normal. Now things look as expected - good blacks and no washed out image.

But based on what I'm reading - this is incorrect? The PS4 forces limited?
