Windows 10: Incredibly vague weird grey outlines on my dekstop

Sinds some time I have a kind of outlines on my screen whenever playing videogames, watching movies via mediaplayers or browser, or just plain desktop. I have an LGC7 TV connected to a receiver. W 10 x64 1809

This "line' seems to change constantly. Sometimes it is just top, sometimes just right, sometimes just bottom.
But NEVER left.
And sometimes the lines comebine. Like top + right or bottom + right. While other times it is just Top Or bottom or right solo line.

Incredibly weird. So I hope people know what this could be since it is so vague.
And so these lines keep coming and going.. just when I think the problem is gone. It quickly returns.

I tied.
1. changing windows theme
2. changing windows user
3. nvidia driver uninstall +clear settings and re-install


Nothing seems to help so far.

To make a photo is somewhat challenging, but here is one to get a basic idea of the problem.

Weird text outlining- Windows 10

Hi,

Before we proceed, I need more information to help you better.

• 
  What is the exact issue that you’re facing with Windows 10?
  
• 
  What exactly do you mean by weird text outlining?
  
• 
  Are you facing any issue with applications?
  

In the screenshot, I am unable to see any weird outlining. But if you are seeing any issue with the display then I suggest you to try installing all the pending Windows Updates and check for the issue. If the issue still persists then try changing
the resolution and check.

Thanks and regards.
