  • The switch receives too much light

    The switch receives too much light

    In this helpful guide, you'll discover: ► Quick steps to manually adjust your Nintendo Switch screen brightness. ► Understanding the impact of automatic brightness settings and how to manage them. What digital foundry said, was that it doesn't have ABL, which is different. ABL will limit brightness and whites on certain sections of screens to reduce. The Switch is unique amongst popular consoles like the PlayStation or Xbox in that it is portable, and (for some models) also convertible. LCD screens such as the one in the regular Switch (es) also flicker, although the PWM of LCD screens tends to be around 1000 Hz or more — higher frequency, so more difficult.
