Questions, answered
How do I find dead pixels?
Fill the screen with black and look for tiny bright dots. If you spot one, check it against the white, red, green, and blue screens to tell a dead pixel from a stuck one.
Can I check backlight bleed with it?
Yes. Show black in a dark room and uneven glow around the edges becomes obvious — especially on IPS panels. On OLED, black should be almost indistinguishable from the bezel.
Is it useful for saving power or hiding my desktop?
On OLED displays, black uses less power than a bright page. It is also a quick way to hide your desktop during a presentation or call.
