Monitor

[Aim12]

I was just wondering if anyone knew what was on the back of my lcd Monitor? It's a circle with 2 intersecting lines and when they line up the line is green. I was playing around with my custom settings, but I cleared them and the circle and lines are still there. Thanks

You were close. I called canon and it's a leveler.
