I solved it, I uninstalled bitdefender and then it worked

Hello. Today, when i opened my PC i found out that i have "No internet connection". The last time i used it was last night, and it worked like a charm. The problem is from the software itself I guess...

Thanks, this got my problem fixed.

As the title said, I can't find my native resolution, 1920x1080 on Windows 10. I don't know how to fix this and I'm waiting for answers. Thanks.
