OLED Burn In Test For LG C3 TV

Gray screens are useful for catching vertical banding and dirty screen effect, while white and red can expose burn-in from channel logos or gaming HUDs. You get a much cleaner inspection than you would from ordinary video content.

Keep the room dim and let the panel warm up for a few minutes before you judge subtle marks near the center or corners.

The homepage gives you a repeatable set of full-screen colors that make before-and-after comparisons easy. That is especially useful when checking a used LG C3 before purchase or after running the built-in pixel refresh process.

If the same marks remain visible on multiple patterns, document them and compare again later rather than relying on memory.

Persistent shapes that appear in the same location across gray, white, and red screens are more likely to be permanent panel wear than temporary retention. A one-off shadow that disappears after mixed playback is usually less concerning.

Use the homepage again after a rest period so your decision is based on consistent evidence.
