Solid Colors
Black, white, red, green, blue, gray, magenta, cyan, and yellow — the classic solid colors that reveal dead pixels, stuck pixels, and tint unevenness.
OLED Burn-in Test
Solid Colors, Gradients & Retention Check
Detect burn-in and image retention on your OLED or LCD screen. Cycle through solid colors, gradients, and retention check patterns with a short timer to reveal ghost images, discoloration, and uniformity issues.

Features
What This Burn-in Test Includes
Everything you need to check your screen for burn-in, retention, and uniformity.
Gradient Tests
Grayscale, RGB, and inverted gradients reveal banding, color shifts, and uneven brightness across the panel that solid colors can hide.
Retention Check Patterns
Grid and checkerboard patterns make ghost images and stuck-image areas stand out — perfect for identifying image retention before it becomes permanent.
Short Timer
Each pattern is held for a configurable time — from 3 to 20 seconds — so your eye can adapt and spot subtle defects before the pattern advances.
Auto-Advance
Automatically cycle through the full test sequence, or advance manually with taps, arrow keys, or the on-screen navigation buttons.
100% Private
Everything runs locally in your browser. No data is transmitted, stored, or shared — just a pure, private burn-in test.
How It Works
Test for Burn-in in 4 Steps
No app, no sign-up — just a clear look at your panel's health.
Prepare
Set brightness to maximum, disable True Tone and Night Mode, and clean the screen.
Start Test
Tap "Start Full-Screen Test" to enter full-screen mode with the first pattern displayed.
Cycle Patterns
The timer advances automatically, or tap/arrow keys to move manually through solid colors, gradients, and retention patterns.
Spot Defects
Look for dark patches (burn-in), ghost images (retention), or uneven tint (uniformity issues) on each pattern.
FAQ
OLED Burn-in Test — Common Questions
Everything you need to know about burn-in, retention, and testing your screen.
Open this page, tap "Start Burn-in Test", and cycle through the solid colors, gradients, and retention patterns. Look for areas that appear darker or retain a ghost image of the previous screen content — these are signs of burn-in or image retention. Use the timer to hold each test pattern for a few seconds and inspect it closely.
Image retention is a temporary ghost image that fades after some time showing different content. Burn-in is a permanent discoloration or dark spot that stays visible on the same areas of the screen. This test helps you spot both by displaying uniform colors and patterns that make any deviation obvious.
Solid gray, white, and mid-tone colors are best for spotting burn-in because they reveal subtle variations in pixel brightness. Pure red, green, and blue also help identify sub-pixel burn-in. Gradients reveal uniformity issues across the panel, and the retention patterns make ghost images stand out.
True burn-in is generally permanent and may require a panel replacement. Image retention is usually temporary and often fades on its own. Some OLED TVs and phones include a pixel refresh or panel refresh feature in their settings that can reduce the appearance of burn-in or retention.
