Question :

I feel that screen is darker or screen color is different compared to 60Hz when I set the Motion smoothness for screen refresh rate to 120Hz.

Answer :

The refresh rate is the number of times the screen is refreshed every second.

You can use a higher refresh rate when you watch super high-quality animations or to prevent the screen from flickering when switching between things.

The screen will be refreshed more times every second so it will scroll more smoothly.

When you select a lower refresh rate, you can use the battery longer.

Like this, concepts between each refresh rate modes are different and each mode has different display tuning method.

Also as OLED display refresh rate is changed depending on the screen refresh rate, you may feel a slight color differences by refresh rate.

Especially because eyes react more sensitive in dark images or screen, so you may feel more precisely the color differences between refresh rates when you see the dark images or screen.

However this does not affect to the device�s lifespan or performance and is in the device�s normal range of operation.

All Samsung smartphones undergo rigorous internal inspection test, and are always being controlled under Samsung�s high level of quality standards internally.
