Why uniformity matters
Uneven panels can show darker patches, vertical bands, or color tint differences that become distracting during movies, gaming, or reading. These issues are easier to notice on smooth backgrounds.
Even high-quality OLED panels can vary slightly, so the goal is to identify visible inconsistency rather than chase perfect laboratory results.
Patterns that reveal issues fastest
Gray screens are ideal for spotting dirty-screen effect and vertical banding. White screens help uncover pink or green tint. Black screens can show retention or edge glow behavior.
Use the available fullscreen tests from the homepage and keep reflections low. Reflections can hide the exact non-uniform areas you want to inspect.
How to interpret what you see
Minor variation is common and may not affect real use. Strong bands, obvious blotches, or persistent edge tint are the issues most likely to impact daily viewing.
Repeat the same test after the panel warms up. Some OLED behavior changes slightly after a few minutes of normal operation.
FAQ
Which pattern is best for a uniformity test?
Gray is usually the fastest way to reveal banding, dirty-screen effect, and uneven brightness on OLED panels.
Is minor uniformity variation normal?
Yes. Small differences are common, but strong bands, blotches, or obvious tint shifts are more likely to affect daily use.
Should I test the screen when it is cold or warmed up?
Check both if possible. Some OLED behavior changes slightly after the panel has been running for several minutes.
