OLED screens are more prone to pixel defects than LCD panels. Our OLED pixel test helps you identify dead pixels, stuck pixels, and other pixel-level issues quickly and easily.

What Our OLED Pixel Test Checks

  • Dead pixels — Permanently black dots that never light up
  • Stuck pixels — Pixels stuck on one color (red, green, blue, or white)
  • Sub-pixel defects — Issues with individual red, green, or blue sub-pixels
  • Uniformity issues — Uneven brightness or color across the screen

How to Run an OLED Pixel Test

  1. Clean your screen — Remove dust and fingerprints.
  2. Set brightness to maximum — For accurate testing.
  3. Click "Start Full Diagnosis" — The test runs in fullscreen mode.
  4. Inspect each color — White, black, red, green, and blue.
  5. Look for dots — Any pixel that doesn't match the background.
