Windows 10: Second Monitor color banding after KB4551762

I'm getting tons of color banding on my second monitor after today's update. Is anyone else having this issue?

I tried the whole "WindowsColorSystem" solution people had used a few months ago but it does nothing.

Update: uninstalling the update does nothing.

The color on my second screen is very dark and I want to lighten this.

Hi,

Thank you for contacting Microsoft Community.

• Are you using second monitor as computer or TV?

If you are using computer as second monitor then I suggest you to change the color of the screen through the buttons that are on right side of the monitor.

If you are facing the brightness issue with both the monitors then the issue might be due to display, please do let us know with more information regarding this issue.

Hope this information is helpful and do let us know if you need further assistance. We will be glad to assist.

 

S2716DG color banding.

I've been using S2716DG for 19 months now, and while I love this monitor so much color banding has always been an issue for me, and many users reported it as well. It is most prominently visible in videos, and I watch a ton of them every day on youtube. I tried everything ppl say should alleviate the problem:
-custom icc profiles
-adjusting with contrast/brightness/colors in OSD
-adjusting gamma and vibrance in nvcp
and while they did help a little with color reproduction, the banding issue was still very pronounced.
Then,just today,I stumbled upon a trick that apparently works, don't know how and why, but the banding in videos in almost gone like with a snap of a finger. My monitor brightness was at 40% in OSD, and the brigtness setting in nvcp is default 50%. Terrible banding in some videos. Now just today,totally by chance, I discovered that putting the brightness in nvcp at 22% eliminates 99% of the banding for me, to the extent I can't see it anymore unless I squint and try to pick up very tiny details. Then I used the monitor's OSD to raise the brightness and the brightess is back to the same level it used to be before and banding is gone. This puzzles me a lot. Why does adjusting brightness in OSD not remove it, but adjusting it in nvcp works wonders?

Like in this video,before the brightness adjustments in nvcp, banding on the black backround and around the red album cover was clearly visible from 2 metes away, now it's almost completely gone even if I'm sitting close.


Not only banding on colors is greatly reduced, white looks a lot less "dirty" than it used to be before,colors are more vibrant. Quite frankly I'm stunned, the the monitor has never looked that good..... It's been 19 months I've been using it with banding and sort of greyish white color....
