4k TV ( 55 inches but not only )

[Lenux]

Does anyone here using a TV 4k LED, QLED, LCD ( 55 inches but not only ) with DCS World ???

I have some questions about

Doesn't matter if it's Samsung, Sony, LG or whatever ( no OLED )

Thank you

[MrReynolds]

I'm on a 43" Samsung.

Everything's fine frankly. Also got a 4k monitor and won't go back.

 

I do have to play on game mode as the screen doesn't look right if it swaps to another profile.

 

It's not as if my system can go >60fps at the moment anyway !!!

 

Any questions fire away.

[Lenux]

So, you play DCS right now, on the 43" Samsung ?

[streakeagle]

I play on a 49-inch TCL 4K TV. It looks and plays fantastic.

4k TV ( 55 inches but not only )

 

Playing DCS while sitting next to a large screen TV with a perfectly calibrated TrackIR is pretty hard to beat. Make sure to enable Vsync or Gsync if your TV supports it for super smooth gameplay, great framerate even at 4K on my system.

What's your TV, Supmua?

Size, resolution, etc

I uploaded here a very short video, please have a look

You better download the file, it's only 119 MB

Make sure you're watching it on a larger display, and please tell me if you can see something around the clouds

Some weird banding and posterisation

I'm 95 % sure, the issue it's from the game itself not from the TV / monitor ...

I looked at your video. I do not see any banding or posterization, so your TV needs calibration. Make sure it's properly calibrated, especially the gamma and black level setting.

 

Test your TV here

I'm using LG 4K OLED 55 inch.

Thank you

I attached a screenshot now

Are you sure you can't see this ??

No banding on my TV.

[streakeagle]

Limitations of the color palette being used cause that type of banding. i.e. in the old days of CRTs, 16-bit color tended to have that kind of banding compared to playing in 32-bit color. Different TVs have different color capabilities... especially over an HDMI cable with a 4K signal. When you start reading up on it, you will find it a little confusing as there are several different standards depending on available bandwidth and hardware capabilities. Depending on the model of TV, it can also matter which HMDI port you use to get the maximum quality signal possible for PC purposes and you may have to manually specify the color format being used rather than relying on the gpu/windows drivers to pick what is best for you. Some TVs may not support the highest quality formats over an HDMI cable to a PC.

 

My old (2006) 46-inch 1080p Mitsubishi LCD TV had one of the best color ranges you could get back then on the relatively new large panel TVs. It had a even dedicated VGA port to guarantee PC compatibility. Yet it tended to have banding issues on blue skies.

[Lenux]

streakeagle, did you see the video ( and printscreen ) I attached on this thread ?

Can you see this banding ? I'm not even sure if it's color banding or posterisation or even from the game itself.

But when I fly very close to the clouds, they look weird.

I will upload here, another short video

Please make sure you watch it on some large display, and tell me if you see this, on the right side, near the cockpit.

After I've read tons of stuff about this, I came to the conclusion, nVidia software is the culprit.

No dithering, compared to AMD drivers

Right now I have at home 4 different Tv's, 3 Samsung, different models, and 1 Panasonic. All 4K

I can't believe that all 4 TV's suffer from the same issue.

I tried a lot of nVidia CP settings, TV settings, the issue is still present

Maybe the DCS engine is old, I don't know.

I'm running Windows 10 x64, latest version, but I tried with some older versions as well

I also tried with more than 10 different nVidia drivers

When I watch the same video, on my TV, from the USB stick, right on the TV , with Windows turned off, it looks a bit better.

Right now I have an Samsung Q90R - 55 inches as PC monitor, everything else looks amazing. Even DCS World. But not near the clouds :)

Only through the clouds, very very close to them

I can't see some color banding when I watch the sky, or at night, the Moon, etc

 

 

" Limitations of the color palette being used cause that type of banding "

Where is the limitations coming from ? From my GPU software ? From my display ? From DCS engine ?

Color limitations can be from the TV not supporting the wider color spectrum or it can be from the particular color format being selected by windows/gpu driver over the HDMI cable. The 4K signal pushed the limits of HDMI bandwidth, so some hardware needs to either keep the refresh rate down to 30 Hz or sacrifices color capacity to hit 60 Hz. But even if your TV's HDMI port and HDMI cable supports the full color format at 60 Hz, Windows/gpu driver might not have automatically chosen to use it. I haven't messed with this in a while, so I would have to look up the exact settings you need to look at. I had studied it before choosing a TV and played with it when I first got my 4K TV.

[streakeagle]

Here is someone asking about it for their nVidia gpu/tv combination. Use this discussion to search the internet for more info on 4:4:4, because if you aren't already using 4:4:4, you should be.

Your pic looks the same on all my TVs and monitors, as well as iPads (i.e. no banding). That Samsung model is supposed to be an excellent TV so I don't think it's the display itself, perhaps it's the way you set it up either via TV setting or NVIDIA control panel or DCS gamma setting? Does your TV show any banding or color crushes on those TV test websites (you may have a white crush if it only happens in the bright area)?

[Lenux]

I already have 4:4:4

HDMI 1 - as PC, on the TV

Supmua, can you please tell me, on the http://www.lagom.nl/lcd-test/

Which test I should try, for the color crushes ?

I did try the color banding test, I'm not sure but for me it looks okay.

Should I try to make a photo, with my mobile phone ? So you can see exactly how I see it

By the way, this Samsung, Q90R is one of the best from the Samsung TV's, and I even own the Q9FN, a lot of people say, it's the best Samsung TV, in the history of Samsung, and hard to match

I could try with another cable, I have one DP to HDMI ( adapter )

I made a picture with my mobile phone ( banding test )

Please have a look and tell me what you think

Did another test, this time with ReShade - Debanding

The issue is 60 - 70 % gone but with the loss of quality - clouds

I'm not sure if my ReShade - Debanding setting are ok, I attached a printscreen

If anyone has more experience with ReShade - Debanding, please give me some advices.

So, that's a software issue, 100 %

No TV hardware

I'll keep testing

 

Thank you

I recommend looking at the contrast, gradient, black level, and white saturation pages (without using Reshade), and make adjustments from your TV settings. Just follow the instructions, they’re fairly intuitive. Then you can start going into color and white balance, if needed.

 

Making sure that you have a corrected calibration is the most important step (not just for TVs, any peripherals), do that from TV’s own settings before using an external software to change the TV’s behavior—because you want to fix the cause of the problem first rather than treating the symptoms that resulted from the problem.

Would a calibrator help, for a TV as PC monitor ?

Something like this

Yes, but only if your TV is to be strictly used with your PC. Imagine using the same TV with a PlayStation or Blu-ray player, then your PC software calibration will not apply. So it is better to calibrate via the TV setting first.

[Lenux]

I tried to calibrate with the TV settings, but it's very hard, because one setting breaks the previous one

I use the TV 100 % for PC monitor

[Supmua]

Unfortunately I don't know enough about Samsung TVs to tell you what to do since I never own one, and TV calibration can get complicated but it is still not rocket science.

 

For LG TVs I typically start with BT.1886 gamma setting, then go to calibrating websites mentioned in earlier post and adjust contrast, brightness, sharpness, black level according to those pages to get optimal images. Then white balance and color balance. If you don't know what I'm talking about then don't worry about it, maybe start with Windows built-in software calibration and go from there.

[Lenux]

Supmua, do you fly with Dynamic Weather ??

 

LE : I forgot to mention something.

About 7-8 months ago, I purchased the AMD Radeon VII but I sent it back because of the poor performance.

I did some testing, but mostly on X-Plane 11 and the banding was almost gone.

Same with DCS World

That's why I said before, a lot of people blame nVidia ( software ) and some of them say, Windows 10 updates, starting last year May - June, added some banding as well
