Prepare the testing environment
Clean the screen first and raise brightness to a level that makes defects easier to see without introducing too much glare. A darker room helps reveal gray uniformity and black-level issues.
Disable vivid or adaptive color modes if you want a more neutral read on panel behavior. Then load the homepage and switch through different fullscreen patterns.
What to look for on each test color
Black helps reveal glow, crushed shadow detail, and retention. White helps identify color tint and dust-like defects. Red, green, and blue help expose stuck subpixels and color imbalance.
Gray is useful for spotting uneven brightness bands, dirty-screen effect, or subtle panel blotches that may not appear on stronger colors.
How to record your findings
Compare the center and edges of the display, then check common UI areas where static elements usually sit. If a defect remains visible on several patterns, it is more likely to be hardware-related.
Use the same device settings every time so your comparisons stay consistent. Repeating the homepage test over time makes gradual changes easier to notice.
FAQ
Do I need special equipment to test OLED quality?
No. A clean screen, controlled lighting, and fullscreen browser-based color patterns are enough for a strong first-pass inspection.
Which screen colors are most useful?
Black, white, gray, red, green, and blue reveal most common OLED defects including tint, retention, and dead pixels.
Should I test at maximum brightness?
High brightness can help reveal issues, but use a stable level that avoids heavy glare so you can compare results more consistently.
