Question 1

What is a black screen test?

A black screen test displays a completely black image on your screen. This is essential for checking backlight bleed (on LCD/LED screens) and verifying true blacks (on OLED screens). It also helps identify stuck pixels that appear as colored dots against the black background.

Question 2

How do I perform a screen bleeding test?

To perform a screen bleeding test (or backlight bleed test), use our black screen tool in a dark room. Set your screen brightness to 100% and look for any light leaking from the edges or corners of the display. This is common in IPS panels but should not happen on OLED screens.
