Backlight bleed and IPS glow explained

LCD screens use a backlight behind the panel. Light that leaks around the edges is backlight bleed. IPS glow is a sheen that changes with viewing angle. Test in a dim room with the black screen above.

Kroki

  1. 1

    Test at your normal brightness

    Maximum brightness in a pitch-black room exaggerates bleed far beyond normal use. Use your everyday settings.

  2. 2

    Move your head

    If a glow shifts or changes as you move, it's IPS glow, a property of the panel type. If it stays fixed at the edges, it's bleed.

  3. 3

    Check with real content

    Watch a dark film scene or play a dark game. If you don't notice it then, it's within normal variation.

  4. 4

    Return or claim if it's severe

    Bleed that's obvious in normal use may qualify for a return within your retailer's window or a warranty claim.

  • OLED screens have no backlight, so they can't bleed. Look for uneven dark greys instead.
