This Free online OLED Burn-in Test uses full-screen color patterns and grayscale steps so you can spot burn-in, dead/stuck pixels, and uneven brightness in seconds. The image below shows what a typical test view looks like.
Comprehensive Guide to OLED Burn-in Check
“Burn-in is the permanent discoloration of a display caused by uneven usage of pixels. Our MONITOR TEST tool helps you identify these issues early.”
Welcome to the most advanced Free online tool for checking display health. Whether you just bought a new OLED TV or want to verify the condition of a used monitor, our OLED Burn-in Test provides a comprehensive suite of patterns to detect every common display defect.
Why Use Our OLED Burn-in Check?
Modern displays, especially OLEDs (Organic Light Emitting Diodes), are susceptible to a phenomenon known as burn-in. This happens when static elements like TV channel logos, game HUDs, or taskbars are displayed for extended periods. The organic compounds in the pixels degrade unevenly, leaving a "ghost" image behind.
- Full-Screen Colors: Pure Red, Green, Blue, White, and Black backgrounds to isolate sub-pixel defects.
- Grayscale Uniformity: Check for banding and "dirty screen effect" (DSE) common in large panels.
- Dead Pixel Finder: Easily spot stuck or dead pixels that stay black or light up permanently.
How to Perform a Monitor Test
Using our tool is simple and effective. Follow these steps to perform a complete OLED Burn-in Check:
- Clean Your Screen: Ensure your display is free of dust and smudges to avoid false positives.
- Dim the Lights: Perform the test in a dimly lit room to spot subtle defects.
- Enter Fullscreen: Click the "Start Auto Test" button or select a specific color.
- Inspect Carefully: Look for dark spots (dead pixels), bright spots (stuck pixels), or faint shadows of previous images (burn-in).
- Check Uniformity: Use the gray patterns to see if the brightness is even across the entire panel.
Important Note on Image Retention
Not all "ghosting" is permanent burn-in. Temporary image retention is common on IPS and some OLED panels and usually fades after a few minutes of watching varied content. If the image persists after running our color cycle or a "pixel refresher", it might be permanent burn-in.
Understanding Display Technologies
While our tool is named for OLEDs, it is equally effective for all display types:
OLED / QD-OLED
Prone to permanent burn-in. Check for logo shadows and uneven color wear.
LCD / IPS / VA
Prone to stuck pixels and backlight bleeding. Check using the Black pattern.
Regularly using a MONITOR TEST tool can help you claim warranty service before your coverage expires. Manufacturers often have specific policies regarding dead pixels and burn-in, so having photographic proof using our tool can be vital.
