Minor variation is common, especially at very dark gray. Judge the panel at normal brightness and distance, and focus on whether it distracts in real content.

LIMITS

Limits of a browser test

Viewing angle, local dimming, warm-up time, room reflections and brightness strongly affect uniformity. Photos often exaggerate or hide the issue.

FAQ

Frequently asked questions

01What is dirty-screen effect?

DSE is visible non-uniformity that can resemble smudges or bands, often most noticeable during camera pans over flat colours.

02How long should the display warm up?

For a careful comparison, use the display normally for roughly 20–30 minutes and keep your usual picture settings.
