Troubleshooting
Open the test in fullscreen and cycle solid red, green, blue, white, and black while scanning for a dot that stays in the same spot.
Pro tip
Use normal brightness and check several solid colors, then compare with different content to rule out retention.
Common symptoms
- Tiny dot stays dark
- Single pixel stays colored
- Spot stays in one place
Dead pixel test amoled is a quick way to confirm whether a tiny dot is really a pixel issue or just content. You notice a tiny dot during a dark movie scene or when a game loads into a night map. Open the test, go fullscreen, then cycle red, green, blue, white, black, and gray.
A common myth is that one bad pixel always means the whole panel is failing. The key distinction is dead vs stuck. Dead usually stays dark, stuck often stays as a colored point. On OLED and AMOLED, true black can make a dead pixel easier to spot, while uniformity near dark gray can reveal other issues. With AMOLED panels, switching between pure colors and near-gray can reveal defects you miss in normal content. If you only notice the dot in one game or one website, repeat the same fills in a different tab to rule out rendering quirks.
To get a fair result from dead pixel test amoled, keep it simple: - Wipe the screen gently with a microfiber cloth first, dust can look like a pixel defect from a distance. - If you are on a laptop, disable any auto brightness feature for the test. - Use fullscreen mode so borders and UI do not distract you. Then drag a window behind the spot. If it never moves, it is unlikely to be an app overlay.
A quick check is screenshots. If the dot shows up inside screenshots when viewed on another device, it is software or the image itself, not the panel. If it never appears in screenshots but shows on every solid fill, that points to the screen.
