Best uses

A black screen reduces light and creates a clean visual space. It is useful during breaks, audio work or display checks.

It can also help reveal backlight bleed or bright stuck pixels in a dim room.

How to inspect

Open fullscreen, reduce reflections, and look around the edges and corners. This is a visual check, not a hardware repair tool.
