Burn-in test: steps through solid full-screen colors so you can spot faint ghost images or discoloration left behind by a static element. Use the arrow keys or spacebar to change colors, and press Esc to exit. Burn-in fixer: rapidly cycles colors to help exercise stuck sub-pixels and reduce temporary image retention on OLED and LCD screens.

What is Screen Burn-In?

Screen burn-in happens when a static image — like a taskbar, logo, or news ticker — stays on screen so long that it leaves a permanent ghost. OLED panels are the most vulnerable because each pixel makes its own light and ages individually, but LCD and LED screens can show temporary image retention too.

How to use the burn-in test

  1. Click Start Burn-In Test to go full screen.
  2. Step through each solid color with your arrow keys, spacebar, or a tap.
  3. Watch for faint shapes or discoloration that appear in the same spot on every color — that is burn-in or retention.

How to use the burn-in fixer

If you spotted mild retention, click Start Burn-In Fixer. It rapidly cycles colors to exercise your sub-pixels, which can clear temporary retention over 10 to 30 minutes. Set a slower fixer speed for a gentler cycle or a faster one for a more aggressive refresh.

Burn-in is often confused with stuck pixels. If you see a single fixed dot rather than a ghost image, try our dead pixel fixer or run a dead pixel test instead. You can also check your monitor’s refresh rate or see the full monitor test suite for overall display health.

Frequently Asked Questions

Click Start Burn-In Test to fill your screen with solid colors one at a time. Look carefully for faint ghost images, text outlines, or patches of discoloration that stay in the same place across different colors. Those persistent marks are signs of burn-in or image retention.

The burn-in fixer rapidly cycles through colors to exercise your pixels, which can clear temporary image retention on OLED and LCD panels. Permanent burn-in, where the panel is physically worn, usually cannot be fully reversed, but running the fixer for 10 to 30 minutes often reduces mild retention.

Image retention is temporary — a faint leftover image that fades on its own or after cycling colors. Burn-in is permanent damage where a static element has aged part of the panel unevenly. This burn-in checker helps you tell them apart: if the ghost image clears after running the fixer, it was retention, not true burn-in.
