Sorry for the unclear picture, it's just about the best I can get with the camera available at the moment. The circled area of this monitor has what looks like paint dripping, it is in a slightly darker grey color than the rest of the area. This abnormality shows up in other colors as well (not just grey), but I can notice it the most when grey is displayed.
What is this supposed to be? And yes I tried wiping the monitor already so it probably isn't something that's physically on top of the screen.
Thanks
