DELL S2417DG/S2716DG Banding Fix? Sort of...Enabling Dithering

Recommended Posts

Posted · Original PosterOP

Other than the bug with is disabling after screen turn off I haven't really had much trouble with it on 1809

Some people say it would stop working during playing games. It differs. I've read the 23 pages of that crazy odyssey at geforce forum today and people are struggling a lot with this shit.

I can't downgrade my windows anyway. They say one should set the color range to limited and then tweak the color vibrance to save those washed colors. I haven't tried it, but limited colors should be not a good idea. 

 

I hope they will implement dithering in the driver someday. But there is almost no hope :(

I couldn't deal with the limited color range I tried that too. Honestly if it gets broken for good I'll probably make an attempt to sell this monitor and look for something else because it literally makes everything look so horrible I deem it unplayable or maybe I'll switch to team red which don't have these issue.

I used to think it's okay for tn panels until i found out these threads. I have a slight problem when i play quake champions, in the menu there is a black background with mild lights and grey smoke, and that looks terrible. but that's the only thing i noticed over the years. i'm not sure if other monitors would work better and if i can sell it for a decent price.

Ok there might be a fix for that 1903 dithering problem. You gotta try to disable windows color manager calibration loader in the windows task scheduler.

In task scheduler not in the WCM I outlined right?

I hope I'm not too late to the party. Short overview: After playing GTA V, I noticed some odd colors in the sky and dark areas, after checking online I noticed this thing called color banding so luckily I have an extra monitor to test the colors out. I saw something like this:

 

What it should look like

What I get on s2716dg

I found out that it is because of something called dithering. This is because the mix NVIDIA + WINDOWS. Is it a driver problem? Could be. But after installing PopOS thanks to the recommendation youtube video on LTT's channel, I discovered this:


DITHERING OFF

DITHERING ON

This was a breakthrough for me because now I know that this isn't just some random monitor problem, although I cannot seem to get windows to replicated the same gradient smoothing. So I will perform more tests and update the post.

GTA was horrible about it. Especially at night, everything dark looked all washed out and horrible.

So far this is still working for me, granted I'm still on 1809. I've seen a lot more issues with it on the newer Windows versions. Its I guess still known monitors sleeping breaks it.

Could not agree more regarding GTA V but I also noticed it recently whilst playing Hellblade Senua's Sacrifice and it's starting to become annoying. I have a good mind to revert and test this case. I never put my PC to sleep. Only Shutdown and turning back on again. Thanks to M.2 :) Ill do more tests on version 1809, I just wish I had an AMD card to make the last batch of tests and then shove this all in NVIDIA's face.

OK, so I reverted back to version 1809 via the Windows October 2018 ISO update form the Microsoft site. I installed the latest Nvidia drivers 436.30 and got to testing. I checked if I had any color profile activated, none. So I took a picture of the Dark Souls 3 image and then added the Dithering Key in the registry and took another picture.

 

VERY IMPORTANT: I did not notice any difference at first because apparently this monitor has a very high gamma setting. I lowered it to 0.600 and you can definitely see the difference. If i set the gamma higher on my second monitor I can actuality replicate a similar result there too. So definitely lower the gamma.

After

Now after getting this work, I was wondering why it does not work on version of 1903 and I did notice that on version 1809 I have both folders:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\nvlddmkm\State\DisplayDatabase\

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\nvlddmkm\DisplayDatabase\

 

Whereas on the 1903 there is only one of these folders:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\nvlddmkm\State\DisplayDatabase\

Perhaps something is missing on the registry entirely.

 

Thank you very much Rawrso for putting all this together.

Have you tried lowering the gamma? at 1.000 i noticed its too high and you will not see a difference, for me it was 0.600 perfect but some can see this as too dark so maybe tryi 0.700?
