A 144 Hz monitor is a high-refresh-rate monitor that offers smooth, lag-free gaming experiences. The refresh rate is a measure of how often your monitor updates with fresh data every second. The higher the number, the more frequently the screen updates and displays new information and the smoother and less choppy images will appear. If you're a competitive gamer or just want the best possible gaming experience, a 144 Hz monitor is definitely worth considering, especially if you tend to play fast paced games with rapidly changing graphics.
Before buying a 144 Hz monitor, there are a few things to keep in mind. Firstly, make sure your graphics card can support a high refresh rate. Secondly, consider the screen size and resolution - a higher resolution will require more powerful hardware to run smoothly at high refresh rates. Finally, think about what other related features are important to you such as low input lag, response time, adaptive sync technology, and HDR support. A 144 Hz monitor will offer smoother motion clarity than a mainstream 60 Hz display but unless the other related specs such as the screen’s response time are up to scratch, you could see other performance related issues such as screen tearing, ghosting or motion blurs.
It’s also worth considering picture quality before you make a purchase. Many of the budget 144 Hz monitors use TN panels or low quality VA panels which aren’t as good at colour reproduction as other monitors. Colours can often appear washed out and faded. More expensive models handle this better but if you’re shopping on a limited budget, you need to decide what’s more important, visual quality or performance.
