Yesterday I got my TV and immediately I've noticed quite a severe backlight bleed, especially in the top right corner. I've switched from 2016 6 series, so I expected pretty much the same quality, but that is significantly worse.
Is it normal for this series, or I just got a bad panel?
It is possible that when viewing dark contents or when ambient lighting is insufficient, clear cloud-shaped tasks appear on the screen. This effect does not represent a defect of the device or the screen, but is due to the operating mode of the LCD screens and appears on all devices, regardless of the manufacturer.
To reduce brightness irregularities, make the following changes:
Picture Mode: Movie
Games Mode: Disabled
Gamma (under "Advanced Settings"): +1
Black shade: Darker
You can also change these values depending on the environmental conditions to optimize the illumination of the LCD screen.
