Check for existing burn-in or image retention on your OLED, AMOLED, or plasma display. Displays solid colors to reveal ghostly outlines of previously static images. Also useful for detecting uniformity issues on LCD panels.
A burn-in test fills your entire display with solid colors to reveal any existing burn-in or image retention. Ghost outlines of previously static elements — taskbars, logos, game overlays, status bars — become visible against uniform colored backgrounds that they would be hidden on during normal content viewing. This test is especially useful for OLED and AMOLED displays, which are susceptible to pixel-level organic degradation from static content.
Each pixel is an organic emitter that degrades with use. Static bright content causes uneven aging, resulting in permanent burn-in. Mitigation: pixel shift, screen savers, panel refresh cycles.
Same organic technology as OLED. Phone status bars and game overlays are common burn-in sources. Always-on display features accelerate degradation.
Cannot experience true burn-in. May develop temporary image retention with extreme static content, but this clears with normal use. Long-term backlight LEDs may show slight dimming variation.
Same as IPS/VA — no organic compounds to degrade. Very fast response times mean image retention is essentially non-existent on TN panels.

Bright dot on your display? Learn the difference between dead vs. stuck pixels and use our free Stuck Pixel Fixer to flash them back to life without leaving your browser.
Found a bright dot on screen? Use our free Screen Test to locate stuck pixels, try safe fixes, and know when to claim warranty.
Corners glowing or bright patches? Use our Screen Test to tell IPS glow from backlight bleed and decide if you should RMA.
A black dot on white is usually a dead pixel. A bright colored dot on black is usually a stuck pixel. Here is how to check before you try a fix or ask for a return.
