Windows 10: video playback only in black/white

All video playback, from Youtube to zoom to PPT files, originally recorded in color, now only replay in B/W. This just seems to occur in the last week or so of the new year 2021. I'm using Windows 10 ver 1.4.9200.22589, HP ENVY 360 laptop.

Video playback Black and white and TWICE the size

I am gaving problems with the video playback on my computer. No matter what video playback I use, (Except VLC player which plays all videos fine)the video comes out Black and white and DOUBLE the size! This started happening after the last windows update.
Can anyone tell me how to get it back to it's normal state. Some way in my settings? I don't know the exact day it started happening so I can't go back to a restore point..... and before anyone asks it is NOT happening on YouTube, BUT it is happening on the
Netflix app, and the HULU app. Any help?

 

video playback becomes black and white

my windows version is the 1803 and my video files when played are all black and white. Driver update says latest version is already installed. One time i thought a program was causing it since when i closed it the video turned normal now it's gone permanently
black and white. I also tried them in windows media player same problem black and white result.

 

Videos playing in black and white when my laptop is charging

Any suggestions for solving this same problem in Windows 8? I tried the above method by after Step 3 there's no Video playback option as suggested in Step 4.

Thanks!
