This Galaxy S20 guide explains the role of the display refresh rate on Galaxy S20, how to change the refresh rate on Galaxy S20, the limitations of the 120Hz refresh rate on Galaxy S20. Some questions you may have on this feature are also addressed.
The display refresh rate feature on three Galaxy S20 phones are identical. So, S20 in this refers to Galaxy S20, S20+, and S20 Ultra.
What are the 60Hz and 120Hz display refresh rate on Galaxy S20?
The display refresh rate measures the number of times per second the display can redraw the whole screen. So, the unit of the refresh rate is Hertz (Hz, 1/s).
For most smartphones, the display refresh rate is 60Hz. And it is good enough for most users.
Most videos have a frame rate of 24~30 fps (frames per second). Loosely, you can think one frame means one static image on the screen.
So, as long as the refresh rate is higher than the fps of the video, we say the display can handle the video. You can watch the video on such a display.
In reality, the 60Hz display refresh rate allows you to watch the video smoothly.
But some users, mainly gamers, may prefer a higher refresh rate to enjoy more realistic gaming experiences.
The hardware and the software on Galaxy S20 are capable of generating graphic output at very high speed, far higher than 60fps even at the full WQHD resolution.
So, some games can benefit from the high fps if the display can handle the output smoothly.
Galaxy S20 answers such demands with the 120Hz refresh rate display.
As mentioned, the 120Hz refresh rate is not for everyone. You will see the difference if:
- You are playing 60fps (or higher) videos.
- You are playing a few games that can handle/generate output at a rate higher than 60fps. Most games do NOT benefit from a high frame rate.
Anyway, as a new feature of Galaxy S20, the 120Hz refresh rate display (motion smoothness) may improve your experiences with a few games and videos.
How to set the Galaxy S20 display refresh rate?
