windows 10 says 4k tv native resolution is 1080p

[jimmywhite73]

I just bought a Sony XBR65X750D 4k tv to use with my PC. The problem is that both win 10 and nvidia control panel are saying that the native resolution is 1080p and also that the refresh rate is 60hz instead of 120....I'm very confused!
I have it set to 3840 x 2160 but in games the refresh rate is still 60hz?

Well you have to realize that TVs are build differently than monitors. Also what video card do you have

 

[atomicWAR]

Couple of other questions. As mentioned what GPU are you running? Are you running a HDMI 2.0a/b cable? I run an a Samsung 55" Curved UHDTV with HDR for my gaming setup and have a fair bit of experience. If your GPU is not a GTX 900 or newer series or your running not using HDMI 2.0a/b then you can't get 4K though 120Hz @ 1080P should still be available. Also want to make sure you enable HDR and 4:4:4 sub-sampling if you want the best image. Last make sure your input on you TV is labeled in your settings as PC and the HDMI is plugged into the PC/DVI named port on your TV.

I have it set to 3840 x 2160 but in games the refresh rate is still 60hz?

This is list of supported video formats for your TV:

• 
  4096 × 2160p (60 Hz) *1, *2, 4096 × 2160p (24 Hz) *1
  , 3840 × 2160p (60 Hz) *2,
  3840 × 2160p (24, 30 Hz), 1080p (30, 60 Hz),
  1080/24p, 1080i (60 Hz), 720p (30, 60 Hz),
  720/24p, 480p, 480i, PC Formats
  
  *1 3840 × 2160p is displayed when 4096 × 2160p is input
  *2 HDMI IN 2 / 3 only.

So - everything seems to be in order.

TV's only accept up to 60Hz input (excluding 3D), the refresh rate of the screen is something completely different. Unlike monitors the 2 are not the same.

Completely forgot about the HDMI 2.0b. That is true that 4K will be locked at 60hz otherwise.

I have been trying, and trying to reply to you guys but could not.... As soon as I would L/click in the "your answer" box, it would disappear and all that would be there is "add a solution" - VERY frustrating! It finally dawned on my to switch browsers... is this a known issue with firefox?

OK, I have 2 x gtx 1080's so it can't be the gpu's and yes I use hdmi cables...I assume they are 2.0b?

Just read the user manual of your TV.
You're trying to achieve settings, that are not supported by your TV hardware and getting confused/frustrated about it.

I guess that just about says it! Dumb consumer(me) listens to sales guy telling him that he really needs 120hz for PC gaming...points to this TV that doesn't actually support 120hz @4k

 

[atomicWAR]

60hz is fine for PC gaming...120hz is better but hard to find even 1080P TV sets that do 120hz native (a few sonys do but not all) and not just auto-motion (ie 60 hz from your PC/video source then the other 60hz/fps are calculated by TV's CPU to make 120hz which adds a ton of lag). And for 4K, 60hz is all there is for TVs right now again not including auto-motion which you want off for gaming. As long as you have good pixel response time your should be fine @60hz.

Question from jimmywhite73 : "Is 60HZ terrible for 4k gaming?"

I just bought the Sony XBR65X750D 65" TV assuming it being 120hz refresh rate it would offer 120hz refresh rate on my PC for gaming...I was wrong! I only get 60hz!
I guess I'm trying to decide if it's worth the hassle of returning said TV and losing restocking fee's etc + my time and effort of disassembling and repackaging the thing, then trying to fit it all into my small car(corolla) again.
Bottom line....is 4k gaming a waste @60hz? or does the 4k part make up for it?

no 60hz is fine I posted in your other thread. I use it myself on a 55" 4K. as long as you have good pixel response time it shouldn't be a problem. In fact it is tough to even get a monitor that does >60hz for 4K though some are just now starting to hit the market. anyways rtings.com did a good review of your TV. I looked at it myself but choose the samsung un55ju7500 because at the time it was considered the best UHDTV for gaming. anyways here's a link below to yours reviewed. Blur test (pixel response) was good which is ideal for gaming.

You just put a smile on a very worried face!

I really should have gone with a smaller TV with better features but the problems was this...I have a very good 60 inch plasma 600hz(subfield - whatever that means)1080p That is barely 2 years old. I couldn't go with a smaller TV then I was using, so I guess my thinking was, in order to justify getting a new TV when the one I currently had was still working great was to have it 1. bigger & 2. For it to be 4K.

Anyways, next question.... Win 10 and NVidia control panel both say the TV is native 1080p so in order to get the ycbcr444 working It had to be set @ 1080p so I did that. So for 4k gaming I guess I just change it in each game to 3840x2160? Then what am I supposed to do if I want to watch HD movies that I've downloaded to my PC...watch them in 1080p instead of 4k?

To be completely honest, when I had the win 10 and control panel set to 3840x2160 I was still able to apply HDR. The ycbcr444 @ 12bpc was not available but everything looked really good and I wasn't playing around in 1080p, everything was 4k.
Am I doing this all wrong?

Well it depends on the set. Mine for example is a 8bpc that is compatible with HDR10. So obviously mine is one of the faux HDR sets only being 8bpc. It doesn't quite reach full HDR spec but it is so close to pulling it off it still looks awesome compared to a non-hdr10 capable TV. Anyways a lot of manufactures are selling 8bpc that are HDR10 "ready/capable". So you may try setting 8bpc with ycbcr444 and see if you can get 4K to work then. My PS4 for example sees my set as HDR even if it is a bit shy on bright/darks as do my PC games that have HDR. Like i said even then it's night and day compared to a standard LED/LCD panel without HDR.

The other thing you can do is try running RGB mode but instead of limited...use full dynamic range. This is popular with people who think ycbcr444's red are to bright or off color. Also I have helped some other folks getting 4K with HDR working with PC. One guy actually had to reprogram his set using my TVs EDID to get it working which may be worth looking into for you.Basically you can program a TVs resolution and refresh rate with an EDID manager/editor. It won't allow your TV to use settings the panel is not capable of but it can be used as a work around when things just aren't working right using windows/nvidia software settings. Though using such hacks are at your own risk. Might be worth googling EDID and trying some things out. Anyways I hope this helps. Keep me in the loop. I'll do my best to help you get it running smooth. Have a good one!

4k gaming at 60Hz has been great for me. You would need 1080 Ti(or 2) if looking for average FPS well above 60 in modern titles with maxed settings. I'm using an OC'd 1080 myself.

 

[jimmywhite73]

AtomicWAR - So after tinkering around I figured out what you knew all along lol....I set native resolution to 1080p, enabled HDR, set the bpc to 12 and used ycbcr444. Everything looks really nice but honestly not $2100+(cdn) better. Honestly these are things that I had to figure out for myself, but if you hadn't replied to my posts I wouldn't be using HDR(12bpc & ycbcr444), I would have it set to 3840x2160 and be missing out on some nice visuals...so thanks bro!

I really wanted 120hz though, and actually thought I had it... that's false advertising man! I wouldn't have spent the money if I knew I wasn't going to be gaming @120hz, I guess I'll wait for 8k @120hz, of course I'll need a new PC for that lol
Thanks again for all your help, you've been invaluable this past couple of days!

I am glad you got hdr working but we should be able to get 4K with hdr 4:4:4 working as well. Have you made any head way with that at all?

Well essentially it is, isn't it? I have my games set to 3840x2160, it's just that the resolution on desktop that's 1080p or should I be trying to make the 4k desktop stick?? Cuz I did at 1 point have the desktop set to 3840x2160 with hdr 444 but the bpc was forced to 8 so I wasn't sure what to do....

So just messing around here and changed the res to 3840x2160 in NVidia control panel and it auto changed bpc to 8 and 444 to ycbr420 which is still HDR right? I haven't restarted my pc to see if it sticks yet, but is this essentially what we want to achieve?

 

[atomicWAR]

you can run the desktop at 1080P if you like and games at 4K; however, the desktop looks very nice at 4K with scaling set to 200. Icons look sharper and all that. The other thing is you want to/should be able to get 4k with at least 8bpc ycbcr 444 if not 10/12bpc. Having it drop you down to ycbcr420 does come at a picture quality cost compared to 444 though input lag is sometimes better on 420 but on your set I believe the 444 is actually a little bit better. In the end it is a question of what you can tolerate, whether its the input lag, picture quality, text scaling etc.

So if I change the res to anything above 1080p I lose 12bpc & 444, but the hdmi signal format is set to enhanced(HDR) on the TV and that doesn't change no matter what setting I use on my PC. FYI, when I set 3840x2160 on the PC, windows auto sets the scaling to 300% which is fine with me as my vision isn't very good. Setting it to 200% is much too small for me, even with the 65 inch TV not even 6 feet away.

I'm curious about win 10 advanced display settings, specifically color profile/color management. Should I possibly be looking for my solution there, instead of in NVidia control panel? What do you have/should I have this set to? Right now its set to - sRGB display profile with display hardware configuration data derived from...calibrateddisplayprofile-4icc
Are there color profiles I can download and install? All these profiles on my PC are rgb...Am I missing something?

 

[jimmywhite73]

OK, so you in fact were right again! I was able to get 444@ 12bpc on 3840x2160 and it all boiled down to me having the hdmi cable plugged into the wrong port! Turns pout port 3 is the right one lol who knew? Funny because I tried switching between both ports 1 & 2.
I wonder if this major win 10 update we got today might have something to do with it?
Either way I would not have gotten this far if it wasn't for you, Thank you!

 

[atomicWAR]

glad you got there!!

 

[jimmywhite73]

glad you got there!!

Out of curiousity...is it normal when using HDR that the win10 calibration tool will no longer function?
The only things I can change are nvidia control panel setting & TV settings.
I guess I'm asking you how I should have things set using HDR? In nvidia control panel should I have it set to 1. other applications control color settings? or 2. use NVidia settings? I think I should be using #1 and then using the tv setting to make adjustments, is that how you do it?

 

[atomicWAR]

I have access to both but I use the nvidia settings because they are neutral. I calibrated my TV first. That rtings.com site I gave you usually has color accurate calibration settings if you don't have the equipment to do it yourself or you do it by eye. Their settings are spot on in my experience or very close.

The only thing you need to do, is go into your NVIDIA Settings, by a right-clic on the desktop. And activate the Dynamic Super Resolution "DSR" in the 3D options. Cheked after the resolution multiplicator up to 4X to get 4k.

(If not, install your Graphic Card Software by looking at your Graphic Card model in the "Device Manager").

If you have an AMD Graphic Card, open AMD Control Center and apply DSR as well. AMD 970 and older only support 1440p.

Hope it helped someone.

The only problem with that is it doesn't work. What happens if you do as described it the DSR function will render the video game at 4K so your right there. But because the GPU, regardless of vendor, thinks the panel is 1080P60hz it will then down sample the image to that resolution just like DSR would if the panel was native 1080P. While the OP would get a small benefit in image quality they do not get their full 120hz 4K image, just a juiced up 1080P at 60hz. It basically will look like they ran mid range levels of anti-aliasing (4x-8x roughly) when in fact it is not on.
