How to Check an OLED for Burn-In
What Is OLED Burn-In?
OLED burn-in, also known as image retention, happens when a static image is displayed for a long time, leaving a faint ghost of that image permanently visible on the screen. It's a common concern for OLED owners.
How to Test for Burn-In
You can check for burn-in by displaying solid colors that will make any ghost images visible. Here's how:
- Display a solid gray screen (around 50% brightness).
- Look closely at the screen from a normal viewing distance.
- If you see any faint outlines or shapes that shouldn't be there, you may have burn-in.
- Repeat with other colors like white, black, and red to confirm.
What to Look For
Burn-in often appears as a faint, yellowish or bluish tint in the shape of a logo, a news ticker, or a game's HUD. It's most visible on a uniform gray background.
Prevention and Mitigation
To reduce the risk of burn-in, avoid displaying static images for long periods. Use the TV's built-in screen saver or pixel-refresh feature. If you already have burn-in, some tools use flashing colors to try to reduce it, but results vary.
