120Hz is a refresh rate that refers to the number of times per second that an image on a display is refreshed. A refresh rate of 120Hz means that the image is refreshed 120 times per second, which results in a smoother and more fluid image.

High refresh rate displays are often used in gaming monitors and TVs, as they can provide a more immersive and realistic gaming experience. 120Hz is also becoming increasingly common in laptop displays, as it can improve the overall user experience for tasks such as scrolling through web pages and watching videos.

Here are some of the benefits of a 120Hz display:

• Smoother and more fluid image
• Reduced motion blur
• Improved response time
• More immersive and realistic gaming experience

Here are some of the drawbacks of a 120Hz display:

• Increased power consumption
• Higher cost
• May not be necessary for all users

Overall, 120Hz displays offer a number of benefits over traditional 60Hz displays. They can provide a smoother and more fluid image, reduced motion blur, and an improved response time. This makes them ideal for gaming and other tasks where a smooth and responsive image is important. However, they also consume more power and are more expensive.

If you are looking for a display that can provide the best possible gaming experience, then a 120Hz display is a great option. However, if you are on a budget or don’t need the extra performance, then a 60Hz display may be sufficient.
