Screen burn-in checks across emissive display types.

How this test works

Use low gray and muted fields to inspect persistent shapes across emissive display types. For OLED-specific near-black and tint checks, use the OLED burn-in test.

1. Prepare the display using the checklist below.
2. Select Start test and allow fullscreen mode if your browser asks.
3. Use the arrow keys, on-screen controls, or click the pattern to move through the test.
4. Exit the runner and save a local observation if useful.

Before you begin

• Lower display brightness
• Hide static desktop elements
• Use each pattern only briefly

What to look for

• Persistent logos or interface outlines
• Uneven gray or color fields
• Shapes that remain in the same location

Use this for a broad emissive-screen retention check

The screen burn-in runner uses low and middle gray plus muted colors to reveal a shape that remains after the original content changes. This general page applies to emissive displays such as OLED and plasma; the separate OLED page focuses more specifically on OLED near-black behavior, tint, and retention. Keep brightness moderate and display each field only briefly. Look for a recognizable interface outline, logo, or region of uneven wear that stays in the same physical location across more than one pattern.

A visible shape does not automatically prove permanent burn-in. Temporary image retention can fade, while broad uniformity variation can be unrelated to a previously displayed image. Note which colors and gray levels reveal the mark, what content was shown before the test, and whether you also see it during ordinary use. The browser cannot measure panel age, determine how long a mark will last, or distinguish every mechanism of persistence. It can only help you make a controlled visual observation.

Avoid turning the check into more static exposure

Do not leave the runner open on one field for minutes while you inspect a photo or discuss the result. A few seconds per pattern at a comfortable brightness is usually enough to see an obvious outline. Afterward, return to varied normal content. Follow the manufacturer’s instructions for any built-in compensation or panel-care cycle rather than repeatedly starting maintenance because a web page shows a faint image. The test does not repair burn-in, and aggressive flashing or pixel-refresh loops are not part of this tool.

On LCDs, persistence and dark-screen variation have different causes from wear on emissive pixels, so do not assume this page provides a universal diagnosis. If the suspected issue is a bright LCD corner, use the backlight bleed page; if it is a broad gray patch without the shape of prior content, use uniformity. A tiny fixed point belongs in the dead pixel check. Choosing a pattern by the shape and display technology makes the observation more informative than labeling every dark-screen difference as burn-in.

Document persistence without claiming certainty

If a logo-shaped mark remains visible, record the display type, brightness, picture mode, pattern, location, and how recently the original content was displayed. Repeat a short check after a period of varied normal use if the maker’s guidance permits it. A mark that becomes less visible may have involved temporary retention; a shape that remains warrants discussion with the maker or retailer. Even then, a short browser check cannot establish an exact level of uneven aging or predict future panel life.

Phone photos can exaggerate subtle low-gray variation through exposure and processing, so begin with what you can see at normal distance. A photo may document location but not quantify severity. If the shape distracts during everyday content, check the current service and return terms for your model. This page is a safe visual screening aid for a broad burn-in question. For an OLED-specific workflow, use the OLED burn-in page, and for objective panel assessment seek a suitable professional method.
