Скачать или смотреть OLED Uniformity and Greyscale Test - Check your TV for Burn In and Banding

This video is a short test to check for OLED burn-in, colour uniformity and banding.

For me the red gave me clear indications of burn in on a LG 65C6 OLED, newer OLED TV's are definitely much better at resisting burn in and I also checked on an LG 55CX OLED and an LG 77C1 OLED which were perfect.

What is burn-in?
Burn-in occurs when I leave static images on my OLED screen for too long. This can permanently damage the pixels, resulting in ghosting or image retention. To prevent burn-in, I should avoid displaying static elements like logos for extended periods and make use of features like pixel shifting or screensavers.


What is banding?
Banding refers to visible lines or bands that appear during color gradients. It happens due to slight manufacturing variations, causing uneven color reproduction. While OLED technology has improved, banding may still be noticeable in some cases, especially in lower-quality panels, but this is very rare in 2023 as OLED is becoming ever more popular.


What is colour uniformity?
Color uniformity is about how consistent the colors appear across the entire screen. OLED panels can have slight variations in color and brightness, leading to certain areas looking different from others. This issue may be more apparent in large areas of solid color or when viewing the screen from different angles.

You can help to prevent burn-in by avoiding static images and using features like pixel refresh and screensavers if using as a monitor.
