Question Monitor MSI optix mag27c - Help

[Sornclc]

I bought this monitor just a few days ago and the first time I turn it on I noticed something like transparents small lines at the edges of the screen, in black backgrounds these lines are not noticeable, but in gray or blue backgrounds they are super annoying. Is my new monitor damaged?. Should I change it?. Or is there a way to fix this problem?.

Note: these lines were notorious in black backgrounds before too, but they disappeared when I touch something in the Nvidia control panel.

Try this way to verify the problem first, switch another refresh rate, resolution, response time, and free sync.
It maybe related to the display configuration. Try to reset monitor setting to factory default to fix it.
