Very good SDR peak brightness for the LG OLED E8. Slightly lower than the levels measured for the B8 and the C8. The brightness level remains relatively constant regardless of the window size, except when almost the entire screen is lit, at which point the brightness level drops due to Automatic Brightness Limiter(ABL). This is not noticeable to most people during normal use.

The menu option that controls the luminance on this LG E8 is called OLED Light.
