Let’s understand what lies behind the numbers, how to check the hertz on your device and whether to believe marketing statements.

Many people mistakenly believe that high screen refresh rates automatically mean better quality, and it really depends on the task: for reading and watching videos, the difference between 60 Hz and 90 Hz may not be noticeable, whereas in dynamic games or scrolling through social media, it manifests itself brighter. Redmi Note 9 is a budget smartphone, and its screen characteristics are optimized for the balance of price and performance. But what exactly does this mean for the user?

To keep our heads around the coffee grounds, we've collected all the technical data, run tests, and prepared a checklist to check the frequency on your device, and we've also compared the Redmi Note 9 to other Xiaomi models on this parameter so you can make an informed decision when buying or setting up the gadget.
