Question Faint Horizontal line Monitor

[Suphiken]

For some reason, this faint horizontal grey line came out of nowhere as i notice. I didn't hit anything to the monitor. Do you guys know what the causes of this issue? Is it because of graphics card issue or monitor issue? Sorry about me being paranoid of this stuff. It does look normal but it's just I'm a bit worried. I'm using dell g2422hs 165hz and the gpu is AMD RX 570. I had been using this monitor around a year in the half.

Welcome to the forums, newcomer!

I doubt it's your GPU but does the panel exhibit the same line when hooked to another system? Have you tried working with another display cable? You might want to include images of the panel from a dfistance not zoomed in.
