OLED screen test
Use an oled screen test to compare visible patches or persistent shapes across controlled fields. Keep the run brief and follow the display manufacturer's maintenance instructions instead of treating browser colours as panel repair.
Also known as: oled screen test, oled test, oled burn in test, pixel refresher, burn in test, image retention test. Free, online, and no download required.

What the OLED screen test checks
| Check | How it is measured | Fails when |
|---|---|---|
| Colour sweep | The fullscreen controller advances through the registered OLED fields. | A field cannot cover the active viewport. |
| Cycle timer | performance.now records uninterrupted active time. | The tab hides or the cycle is interrupted. |
| Pattern navigation | Arrow keys and the cycle control share one pattern index. | Manual and timed state diverge. |
How to run the OLED screen test
- Prepare the device and close any application that could reserve the same input or media stream.
- Start the oled screen test, follow the live prompt and complete every named control or direction.
- Finish the run, record the verdict and repeat once before changing one setting or connection.
If something failed
Use the existing fullscreen control and check the exposed area. Browser bars or system scaling can change what is visible. Record an incomplete view rather than treating a hidden edge as a passed check.
It cannot prove permanent wear, predict recovery or run panel maintenance. It also cannot calibrate brightness or establish warranty eligibility. The oled screen test supplies fields and a timer; the monitor check guide helps organise a support record without promising a repair.

How to read the result
OLED test patterns for near black uniformity
Compare the same shape. An oled test shows controlled colour fields that can make uneven areas easier to describe. Record brightness, room light and the visible location. A near-black pattern is a comparison surface, not a calibrated luminance measurement or a diagnosis of pixel wear.
Does the shape disappear after ordinary varied content or the manufacturer's documented maintenance? Record the before and after observation rather than declaring temporary retention or permanent burn-in from one sweep. An oled burn in test cannot run firmware compensation or predict whether a visible trace will recover.
The name pixel refresher can refer to browser colour patterns or to a display's own maintenance function. They are not interchangeable. This image retention test only displays fields. Use the screen test for a separate point check, and consult the exact model's instructions before choosing a maintenance step.
How the oled screen test works
The OLED sequence advances a fullscreen pattern index from an animation-frame clock. Elapsed time is based on performance.now rather than interval counts, so delayed frames do not lengthen the reported duration. Manual arrows update the same index, and leaving fullscreen stops the active cycle while retaining the elapsed value. Follow the how to test monitor when you need a complete troubleshooting sequence.
Use the oled screen test in a visible foreground tab and keep the device, connection and duration unchanged. Repeat the same action enough times to separate one missed browser event from a persistent pattern. Record the displayed value before changing one setting, then run the same sequence again.
During OLED screen test, the live readouts update from bounded counters and recent samples. Complete every requested direction, key, channel or phase before finishing. Reset between devices so events from an earlier run cannot alter the next verdict, and keep the tab focused whenever timing or event frequency is part of the result.
What the result can establish
Observe at comfortable normal brightness without leaving static controls over the field. Record any repeated trace, then compare normal varied content. Stop if the manufacturer's operating guidance differs; the page timer does not define a safe or effective repair duration.
Use the oled screen test in a visible foreground tab and keep the device, connection and duration unchanged. Repeat the same action enough times to separate one missed browser event from a persistent pattern. Record the displayed value before changing one setting, then run the same sequence again.
Read pass as confirmation of the collected sample, warn as a repeatable concern that needs comparison, fail as a missing or abnormal signal with a direct next action, and inconclusive as too little valid input. The number in the detail explains which threshold or count produced the status for OLED screen test.
Measurement limits
A browser pattern cannot run panel firmware maintenance or guarantee that persistent image retention will change. The tool only provides controlled fields and an accurate page-run timer.
The OLED screen test reads only signals that the operating system and browser expose to this page. It cannot inspect physical wear, firmware queues, electrical contacts, analogue circuitry or another application's private processing. A clean run confirms the observed sample, while an intermittent fault may require a longer repeat under the same conditions.
Browser scheduling, power saving, wireless transport, display timing and background work can alter the values shown by OLED screen test. Compare results only when those conditions match. Do not treat a small difference as a hardware change unless it repeats across several controlled runs.

OLED screen test questions
What is the difference between burn-in and image retention?
Temporary image retention can change after other content or documented maintenance, while a persistent trace may need support evaluation. A single colour sweep cannot establish permanence. Record whether the shape remains under the same conditions over separate observations. This browser cannot inspect pixel wear or determine the correct service action.
Can this pixel refresher remove OLED burn-in?
No. The browser pattern cannot run the panel's firmware compensation or restore worn emitters. A pixel refresher in the display menu is a different function and must be used according to that model's instructions. Do not assume prolonged browser colour cycling is an approved repair or substitute for support.
How long should I run the OLED burn in test?
Use the selected duration only as a page-run timer, not as a repair prescription. Keep brightness comfortable and stop if the display manufacturer's guidance requires it. The OLED burn in test does not define how long a panel should run maintenance or guarantee that a visible trace will change.
Which OLED test pattern shows near black uniformity best?
A near-black field can help compare a repeated patch under fixed room light and brightness. Record the same location from the same angle on more than one field. The page cannot measure uniformity numerically or identify a physical cause from the appearance, so avoid a universal normality threshold.
How can I reduce the risk of OLED burn-in?
Use the exact display model's current instructions for brightness, static content and built-in maintenance. This page cannot inspect whether those protections are enabled. The oled screen test should document a symptom, not replace the manufacturer's routine or promise that a particular habit prevents every persistent trace.
How should I repeat the oled screen test fairly?
Use the same display, actual brightness, room light and viewing angle. Record the shape before changing one condition, and compare ordinary content separately from the test fields. Keep the page duration labelled as elapsed observation time. Repeated runs do not make the browser a firmware maintenance tool.
What can the oled screen test not prove?
It cannot prove permanent wear, predict recovery or run panel maintenance. It also cannot calibrate brightness or establish warranty eligibility. The oled screen test supplies fields and a timer; the monitor check guide helps organise a support record without promising a repair.
