Typically, a higher frame rate requires a better graphics card and processing speed, suitable screen resolution, refresh rate, etc. At its most basic level, a display screen works by showing you a series of images, or “frames”. To make a video, the display needs to show a series of frames, one after another. This is called refresh rate. A 60Hz display refreshes its image 60 times a second.
This all becomes important when more people are using their smartphone to view videos while phone manufacturers are touting phones with high refresh rates in their screens. The Google Pixel 4 comes with a 90Hz screen, while the newest Samsung goes up to 120Hz.
For the best viewing experience, refresh rates and frame rates need to work in tandem - if the two are out of sync, things can get pretty ugly pretty quickly. Taking the VIOFO as an example again, viewing a 120fps footage video on a standard 60HZ screen might produce a nasty effect called “screen tearing.” Currently, most laptops, smartphones, and tablet screens have 60HZ refresh rate. Of course, gaming laptops and the latest high-end smartphones can go up to blazing-fast 90Hz and even 120Hz.
