Refresh rates are mostly relevant to PC gaming. The refresh rate is the number of times a monitor refreshes the screen per second. 60Hz is fine for casual gamers, but if you're into fast-paced action titles, we recommend a monitor with a 144Hz refresh rate. This will ensure your monitor never bottlenecks the frame rates generated by your PC. You probably don't need a 240Hz (or higher) refresh rate unless you're a professional gamer. Personally, I use a 60Hz monitor, which is fine for me because the games I play are slower-paced.
