GTX 1080 ti / AMD Radeon 7

This feels like a red herring to me. The images posted look fairly normal, especially the Google maps one you're looking at a low resolution compressed cubemap, yeah it's going to look blocky.

I have almost the same TV and I don't see any problems like this (I do have a Radeon VII, but I don't think that is why, I've tried the TV with my 2080 Ti as well).

One thing worth trying is a factory reset on the TV. This has solved some issues for me.

Also make sure HDR color is enabled on the TV HDMI port, the TV should be in Game Mode, and enable HDR color in Windows display settings. For Nvidia settings, let the TV handle color and set to HDMI Full.

Don't mess with the "HDR+" mode on the TV, it is junk and usually just messes up the picture. Those are the settings I use and should work.
 
What does it mean " red herring"?
HDR color is already enabled on TV HDMI port
If i enable HDR+, it looks more pronounced, the whole color bandings. Way more
And if I try to let the TV handle the color, it looks washed out, like there is way to much gamma, or something like that
Factory Reset on the TV? I did, many times
What's your TV model, cibereality?
 
Why we bustin this guys chops? He said the color looks bad on the 1080. It's his interpretation, and frankly I believe him. NV's colors have been off for years.(y)

Get yourself a Radeon 7, you will enjoy it for sure.

RMA time. Also, test with another card, just in case.
 
Sorry, I don't mean to bust any chops.

A red herrings means something that distracts attention from the real issue.

Meaning that the problem is in my opinion not an Nvidia or AMD issue and likely something else.

I have the Samsung Q7F, which should be very similar in terms of settings. I believe the settings I gave you should work.

HDR mode in Windows will look off unless the TV is in Game Mode. There is also an advanced setting on the Windows color page which will help with the washed out look.
 
Right click desktop -> Display Settings -> Windows HD Color Settings -> Change brightness for SDR content (slider)

I missed the detail that you are using HDR.

HDR is pretty busted on PC. I don't recommend using it 24/7. I only recommend turning it on for specific situations. Such as a game which supports HDR, a Blu-ray, etc. Even then, it can sometimes take a couple of tries for it to work correctly. Such as launching/re-launching a game more than once, before the HDR looks right.

try disabling HDR and see if your color issues go away.

Never used HDR? Or is it 'enabled' in your TV? Which is it? If so, its an HDMI bandwidth 2.0 limitation when HDR is enabled. Of course HDR+ is worse, lol. 4:4:4 + 60hz + 10-bit will never go through HDMI 2.0. Regular (or pseudo) HDR will have to be on 8-bit + dithering, and that will result in some visible banding in some situations. An R7 will not solve it either, since it will also use the HDMI 2.0 port. Will only be solved when HDMI 2.1 arrives or you switch to a 4k monitor with DP 1.3.

Yeah, banding in source images and video is common, and even when you have perfect gradients, display banding is also common.

Generally, in the era of digital signals, the GPU is the least likely suspect. If the picture says level 233, it sends 233 to the display. The GPU is just the middleman that should be passing info through (unless the setting were messed with).

Here is banding test:
http://www.lagom.nl/lcd-test/gradient.php

On my calibrated NEC 2490 monitor, it is smooth. On my TV it has banding.
 
I didn't find a fix, Nenu
Unfortunately...
Someone from Samsung should come, this week, maybe.
I watched Netflix ( with the Samsung app) and I see all those bandings, especially when I pause the app
With YouTube app, when I watch from a different angle, I see some magenta - green patches
Dirt Screen Effect also....
I'm just curious what the Samsung guy will say...
But some clouds ( flight sim) look pixelated, and this has nothing to do with color banding / DSE
I'm not sure, just saying
But what makes me more confused : if the panel TV have issues, I shouldn't see nothing on the printscreens.
Example, this printscreen from X-Plane 11, main menu - left side

Thats fantastic, I'm glad they are taking you seriously.
I hope the engineer has enough knowledge to understand the problem.

Thanks to you (lol) I now notice some banding where I didnt before but your issue is a lot more serious.
(for those wondering, I am using the same Q9FN TV as shadowj. Its an incredible display.).
 
He said ( Samsung guy ) he will really try to help me, that's not a cheap panel, and the older KS7500 as well
But the question remains : how comes, I see the color banding on the screenshots?
I shouldn't, actually
As I said before, that makes me more confused
2 more screenshots
I don't know if you can see it
That's awful
I never saw this in X-Plane 11. For this clouds addon I paid 39 USD, so there is nothing wrong with the clouds.
I have actually, 4 clouds addon - payware, all look the same, even the default XP 11 clouds.

I could see it on your previous screenshot, although it is mild.
But once you are sensitive to it and it is worse with a more major application, its not easy to dismiss.

I hoped you would find which device is behind it after trying your second PC/TV and swapping parts.
Please take note, it can be made worse by the OS or graphic driver version as found by contributors to the thread I linked earlier.

I also wonder if, when the problem occurred with your first TV, had that received an update when the problem started?
 
I'm not sure when I updated the KS7500, last time
But if I remember correctly, December 2018
What do you mean by " graphic driver version"?
nVidia driver or Windows WDDM?

Read the thread I linked earlier, beyond post 310.
Windows version 1903 made it bad.
Some people found earlier NVidia driver versions helped make it less bad.
An earlier WDDM version helps (the gfx driver version will change which WDDM you are using).
 
I'm not using Windows 1903
I always have backups ( Acronis )
I did test it with the latest Windows 10, as well. Same story.
Now, I have Windows OS Version 10.0.14393.693 (Win10 RS1 [1607]
Yes, I've read the link, post 310
 
Ok, I wasnt attempting to solve the issue but hoped it may help.
Its best you see what the Samsung engineer has to say.
First hand experience by a qualified engineer will hopefully get a result.
 
I could see the banding in the last screen shot as well....i would get the radeon 7 on order asap. (could always resell it if need be) that banding would drive me nutz for sure lol
 
Did you try selecting integrated graphics in BIOS, and use your 9700k's iGPU as a test?
 
I ordered the Radeon 7, it should arrive today ( 5th June )
When the Samsung engineer comes, I'll have 2 GPU's for test, although, I have a feeling, with the AMD Radeon 7, all the color banding issues will disappear
The TV panel seems to have the DSE, as well, but that's a different story
One last thing : since yesterday, something weird happen, the 8 bpc - output color depth, is greyed out.
It doesn't matter which settings I have, it remains greyed out
I tried to uninstall ( with DDU) the driver, but after I reinstall it, it's the same, as soon as I reboot the computer
I'm not an expert, but it looks like a hardware issue

You need to have display on Native screen ,otherwise it will be grey out and you will not be able to change it.Set native screen ,then use Nvidia settings and switch to 10BIT.

give us before and after pictures so we know which gives a better picture on your setup

It is NATIVE ( if you mean the resolution )
I can't switch to 10Bit, with Output Color Format - RGB
 
Okay, I'm back with the first impression, after about 10 minutes of testing.
Color banding is gone. Not 100 % but WAY better than it was
Google Earth color banding is still visible ( less ) but I don't care, maybe that's the way it looks
Colors look more vivid, I don't know how to explain
Black looks BLACK, etc... Can't believe it.
There is no Placebo. All the colors look better, more vivid.
I didn't test the temps, compared with nVidia
I'll keep testing, and I will be back, but I have some questions, guys : is there any similar software like nVidia Geforce Experience?
Recording and printscreens....nothing else.
How do I know if Dithering is enabled or disabled?
Where / how can I check?
Thank you
 
win shift s is good for screenshots. but i think taking a photo of the display is probably the best way to go in this use case.

I was curious to see how your intel integrated graphics compared as well.
 
Interesting. Well glad to hear your new video card works.

I do think the colors on AMD are better, but it's a controversial topic.
 
There are some settings which I don't really understand ( i used AMD / ATI last time in 2004 )
Could you guys, please, help me ? What should I enable or not ?
By the way, should I enable the Samsung Free Sync ? I use only the native ( 3840 x 2160 ) resolution, for games as well
Thank you

I think it has to do with his specific display....so probably not really meant as a general use
