Why near-black is different from full black
Full black tests retention and dark cleanliness, but near-black is better for revealing whether the panel transitions smoothly through shadow detail.
This matters in movies, games, and dark interfaces where slight inconsistencies become visible in motion.
How to inspect shadow consistency
Use dark gray or near-black patterns in a dim room and let your eyes adjust before scanning the panel slowly.
Look for blotches, patchy edges, or vertical structure that seems stronger than the rest of the screen.
How to judge whether it matters
Mild shadow variation may not bother casual users, but obvious dark-scene patchiness can be distracting in films and games.
Test with both patterns and real dark content to decide whether the issue affects your actual use.
FAQ
Is near-black better than full black for shadow checks?

What viewing conditions are best?
A dim room with low reflection helps you see subtle dark-scene inconsistency more clearly.
Can near-black reveal banding?
Yes. Some OLED banding and patchiness become more visible on near-black backgrounds.
