120Hz with 1080p or 60Hz with 1440p. How do I decide when I should use each?

Hello 😊

As per the title, is there a list of recommendations or application list that gives me a notion when its best to use each combination?

Am looking to use Bixby Routines to switch depending on which application I start. But I don't know enough about it to make the decision.

(Am coming from the Apple ecosystem where I don't have to think for my self, so not sure how to do it! 🤣)

Many Thanks!

@Cuchillo: I'd recommend simply heading to Settings > Display > Motion Smoothness, and settings this to Adaptive. This will give you smoother animations and scrolling by automatically adjusting your screen refresh rate up to 120 Hz where available.

True, but that then sets the resolution to 1080.

Was wondering if some apps would be better at a lower refresh rate and higher resolution?

And other are better at a higher refresh but lower resolution.

1440p will give you a sharper image.
Higher refresh rate will give you less motion blur with fast moving objects on screen.

When you choose to prioritise one over the other will depend on what your doing at the time and how much it matters to you.
For example if you're watching a movie, then 1440p will provide you with a better image.
If you're playing a fast paced shooter game like fornite, then you may want a higher refresh rate so you get less blur when making fast motions on screen.

Ultimately its down to your personal preference and whether or not you can even tell the difference between 60Hz and 120Hz under normal use, in which case it would be best to stay with the higher resolution by default.
