Windows 10: videos appear color-shifted and vertical band on left side

hello,
I'm encountering a problem when playing any kind of video on my windows 10 laptop. I've tried to look in the film&TV settings but couldn't find anything that addressed the issue. Whenever I play videos, wether on browser or from mediaplayer the colours appear shifted with a red or blue "halo" around shapes, as if the colour channels were displaced, and I have a vertical band on the left side of my media player that shows the right edge of the video. Strangely enough I found that pressing the windows key on my keyboard toggles this shift on and off, but of course it is not a fix as part of my screen is occupied by the start menu, and as soon as I close it the issues shows up again. Is there a way or update that fixes this problem?
Thank you in advance,
Andrea

Little bubbles appearing in vertical line on screen

These small round "bubbles" appear on my screen. They move around a vertical band slightly left of centre and activate apps they touch. Cursor vibrates and disappears. Computer is basically useless.

What have I got and what can I do.

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....
