Bought a new monitor and want to test if your new display has backlight bleed? Well, you shouldn’t worry about backlight bleeding that much if you don’t notice it. Most people actually don’t notice backlight bleed or simply don’t care. Backlight bleed is simply a defect where some of the screen backlight leaks a bit extra light around the edges, mostly corners. This defect is noticeable at any angle on a dark scene and is the same color as the backlight, which is white. Backlight bleed is also often referred to as lightbleed.
