2K....4K, what's happening?

[SavageEvil]

Re-read what I've written. The PS4 Pro does the "upscaling" and then sends it to the TV. You're basically repeating what I've said in other words.

I did and that's why I quoted it, I should have put in bold what I was correcting.

Outputting a 4K signal and rendering at 4K are 2 completely different things.

On PS4, it renders at 1080P and your TV upscales to 4K. On PS4 Pro, it renders at 1800P (checkerboard rendering) and then upscales to 4K and then sends the signal to your TV.

This is what I was correcting, PS4 Pro renders natively at 1800p, that checkboard technique is used to reach 4K. 1800p is native and not due to checkboard rendering, if it did the end result would be bad as they are upscaling twice. Just move the checkerboard rendering to the upscale to 4K and it makes sense but as it is it's wrong.

 

[Ryan Taylor]

Your problem is that you are not plugged into an HDMI 2.0 port, HDMI 1.4 does not support 4K output bandwidth constraints. Plug your PS4 Pro into the HDMI 2.0 port for the full fat experience. This is assuming you have a 4K TV, my apologies if you do not and this response can be ignored.




Partially correct, on the Pro it renders the signal natively at 1800p then uses checkerboarding to reach 4K. Checkerboard is the temporal rendering technique using the highest image output possible natively then upscaling to your target resolution reducing artifacts that occur when rendering from lower resolutions and less strenuous on the GPU furthermore the TV isn't upscaling anything(if it's game mode is the real deal that is) and you wouldn't want it to since that creates lag in video games.

All of my ports are 2.0 compatible. That's why I'm confused as to what is wrong lol.

Check your documentation on whether you have the compatible HDR10 compliant hardware. Also you PS4 Pro can detect if you are connected to a HDMI 2.0 port by checking the connections using the software installed in it. In the Video section of the settings screen. Also check that your cables are also full bandwidth 2.0 cables as well.

My guess it's probably the cables, so look at those.

 

[Ryan Taylor]

I'm still having issues with this... After I set the screen settings it says I'm running in 4k HDR.
But then it says I'm running at 2k output mode and to prioritize frame rate. Is this a glitch??? I'm using the stock PS4 pro hdmi cable so it should work for this game at 4k HDR. And all of my HDMI ports support HDMI 2.0

 

[Ryan Taylor]

Also it won't let me change the output setting, it's stuck at 2k output.

I don't have a ps4 pro (or even the game yet) but from what I've read there are two modes. Prioritise Framerate (which you are on) and Prioritise Graphics, I think the second is the option you need to select for 4k.

It won't let me choose another option...

 

[Ryan Taylor]

The PS4 Pro is running at 4k with HDR enabled on the home screen, so I'm confused as to why the game is locked at 2k. I've never had any other issues playing my other games at 4k with HDR. Horizon Zero Dawn plays just fine...

Sorry I can't help you then. It's very hard to know what the issue is without being able to try. Maybe some full screen shots might help???

Maybe try YUV420 instead of RGB. No TV can display 4K RGB HDR, the bandwidth is too high so they either display YUV420 HDR or RGB (NO HDR). Games I've tried with HDR automatically switch down but maybe GT Sport doesn't do that. I'll play around with my system and update if I find anything.

I just tried that, didn't make a difference unfortunately lol. Thanks for the help though.

 

[SavageEvil]

Does it run 4K in quality mode? If it does according to your earlier post with the photos the there is nothing wrong when you select performance or Prioritize frame rate, this means the Pro is running it at a native resolution of 2K with unlocked frame rate. It cannot run 4K across all modes in this setting, in 4K quality mode replays are locked at 30fps. Quality mode dumps the upscale and runs replay mode unlocked but keeps native output(which is not 4K) so that's why you see the 2K prioritize frame rate.

I'm trying to change it to 4k quality mode but the game won't let me change it from 2k frame rate mode. It's bizarre...

Ok that's bizarre, did you try running the display assistant to set it to quality mode?

 

[Ryan Taylor]

Yeah I used the assistant. It set th e display mode to 4k with HDR but when I go into the display settings it's stuck at 2k.

 

[SavageEvil]

Yeah I used the assistant. It set th e display mode to 4k with HDR but when I go into the display settings it's stuck at 2k.

I think once it's set to that, just leave it in quality mode. What does the TV read out say it's getting for a signal?

Also try running a replay once you set it to Quality mode, if it's not running in 60, you're definitely in quality mode. I'm not sure but I think you should ignore the words written on the setting itself. Once the console and game detected your display you should be able to set the game to output 4K Quality and when the second option comes up select quality mode. Despite it saying 2K mode but on a 4K screen you will get 4K output.

Same issue here, both demo and release. Assistant shows 4k HDR, but can't change from prioritize frame rate to quality mode - the option is greyed out. Samsung MU8000.

That's very strange, I'm using a 1080p TV and can switch freely between quality and performance modes. I'll have to do some checking on that TV.

Do you have HDMI UHD color activated on your Samsung? Activate that if it isn't and try the setup again to see if you can get 4K@60fps. You may have to scour the settings for that, I'm not certain of it's location myself as I'm not familiar with Samsung TV's all that well.

@Ryan Taylor Do the same with your TV, from the picture menu enable HDMI UHD color. If it doesn't work both of you rename that port to PC.

This is exactly my issue as well. I'm using a Samsung ks8000. And yes my uhd color is enabled for all of my HDMI ports

 

[SavageEvil]

It's the TV that's causing the issue, Samsung for some reason won't display 4K @60fps unless the HDMI port in use is labeled as PC which gives it ability to run 4K 4:4:4 @60Hz this should let you get 4K @ 60fps but you never know. Samsung really needs to put these options as check off points for any HDMI port you wish to use for gaming related activities. Not sure that will work though since it is technology.

 

[Ice9ine]

I am having exactly the same issue Ryan. PS4 Pro on samsung 4k HDR 40" and every other game HZD etc its in 4k HDR no problems. GTS says im running 4k HDR as does my tv but settings in GTS wont let me change from 2k , prioritise frame rate (ps4 pro mode) or similar.

All i can think of is as it knows im running 4k it cant enhance graphics any more so it defaults to the 4k frame rate option which is why 1080p people seem to have the option although they would only get frame rate or gfx at 1080p option im guessing obviously.

Keep me in the loop..i would love to see it look even better if thats even possible lol.

My HDMI cable is currently plugged into the PC Slot. I've tried every port but still doesn't work.

Only thing I can think of is some communication issues with the software governing GT Sports 4K output and your Set. Have you tried disabling HDR to see if it will allow Quality mode?

Yes I've tried cutting out the HDR but 4k still won't show. I think you might be right about the software regarding the game and Samsung

 

[SavageEvil]

Sorry I haven't purchased my 4K set as yet so I can't really give you more information. I'll look up other things to see what could be workarounds for it though.

Wish I would have caught this earlier. If you got your TV hooked up right and your output from the PlayStation is going to your 4K TV has a 4K signal, the options under video output (2K output mode for PlayStation Pro console) is grayed out, that is normal....

The thing you are trying to change is if you are using a PlayStation Pro on 1080p screen. Then you could choose to do some supersampling, frame rate or other options...

When Gran Turismo sport runs on a pro to a detected 4K TV, it has one option but don't worry it's still running 60 frames per second at checkerboard 4K...

Are you sure about that? I've saw digital foundrys vid on YouTube and their option was 4k not 2k in the settings

I have a similar set up and notice the same thing within my menu. I Just read this from the GT online manual:
“2K Output Mode for PlayStation®4 Pro console: Select the mode to use for PlayStation®4 Pro console 2K output. 'Prioritise Quality' offers high picture quality using the same amount of visual information as 4K output (4K downsampling), while 'Prioritise Frame Rate' is a response-oriented mode (2K MSAA) that still offers higher picture quality than when playing on a PlayStation®4 console”
So is 2k output better for the PS4 pro??
I’m a little confused

IMO start with quality priority for the best image quality, if you suffer from frame rate issues then drop to frame rate priority.

standard ps4 is 1080P but if you have a 4k HDR tv that does up-scaling then you should get 4k I do my tv has a small box at load up telling me its showing 4K HDR

Some TVs indeed have outstanding up-scaling capabilities. I have a 65" 4K HDR TV, even when I play standard DVDs the image still looks great (depending a bit on the DVD itself as well, some have highly the movies that come on multiple DVDs like my LOTR set have the best image quality for being a DVD).

In regards to up-scaling you have 3 options on where to do it :
1) the console
2) the AV receiver / amplifier (if you have one)
3) the TV

In my case the PS4 Pro costs about 400 EUR, the amplifier is about 400 EUR as well, the TV was 4000 EUR back in 2015. So in theory the up-scaling should be better on my TV since that's high-end quality equipment, the other 2 are only mid-end so they should just put through the signal the way they get it. Then I can also see on my AV receiver info display what the source picture is.

Same issue here, both demo and release. Assistant shows 4k HDR, but can't change from prioritize frame rate to quality mode - the option is greyed out. Samsung MU8000.

I had that issue as well in the GT:Sport demo where it was set to prioritize frame rate (greyed out) and for me Horizon Zero Dawn worked as well where I could choose between quality or performance settings. Not sure what the issue here is but once my X1X Scorpio arrives early November I will revise my hardware connections. I still run some older HDMI cables now so maybe that's the issue.

Not sure if the PS4 Boost Mode could have anything to do with it, it should not affect it but have you tried switching boost mode off? (if it's on)

 

[SkylineR88]

change your colour format

there is no 4k output mode option, the option is for 1080p only, 4k output has no option other then hdr on or off

 

[Ice9ine]

So using a Pro to my 4k Samsung with HDR mine defaults to 2k frame rate option greyed out. The only way i can get the quality option is to change console display output from AUTO to 1080p. I then see Quality option in GTS but output is 1080p to my 4k screen which looks way worse than the 2k Frame Rate one. Still not sure how people allegidly get a 4k option unless they mean the set up wizard thing where it says 4k and HDR on.
