Refresh rates are the frequency with which the image on a computer monitor or similar electronic display screen is refreshed, usually expressed in hertz. Breaking this down into simpler terms with meaning, essentially refresh rates are the number of times the image being displayed on your monitor is regenerated to prevent flicker when viewed with the human eye. Naturally, this means the higher the refresh rate of the monitor, the better performance you’ll see when gaming, for example, boasting silky smoothness no matter how fast you’re moving that mouse about.
The most common refresh rate you’ll see is usually 60Hz and is plenty for the everyday user but with more advanced monitor tech entering the market, you can pick one up that has a massive 240Hz refresh rate. Higher refresh rate monitors are usually the go-to choice for gamers who normally opt for between 144Hz and 240Hz variants, predominantly leading to increased performance in multiplayer titles.
