How to look for persistent OLED image shapes
You do the observing.
We provide the patterns.
- 01
Use your usual brightness. Turn off night color filters and reduce reflections in the room.
- 02
Start with the gray patterns. Look for outlines of logos, menus, or other familiar shapes.
- 03
Switch to red, green, blue, and white. Notice whether the same shape remains in place.
- 04
Take a break, then check again during normal use. Record persistence and viewing conditions.
BEFORE YOU DRAW A CONCLUSION
Your screen check questions
Can a single test prove permanent burn-in?
No. A lingering image can be temporary or persistent. Compare the same area after varied normal use and your model’s recommended care process. One short browser session cannot establish permanence.
Does 5% gray mean 5% screen brightness?
No. It means a rounded digital RGB level, here RGB 13, 13, 13. Your actual light output depends on the panel, brightness settings, color management, and other conditions. The website does not measure it.
Should I leave the test running to repair the screen?
No. These are short visual inspection patterns, not a repair or endurance routine. Move through them at your own pace and return to normal use. Follow only the panel-care instructions for your exact device.
