When it comes to choosing the perfect display for your gaming, video editing, or entertainment needs, one of the most critical factors to consider is the refresh rate. The refresh rate, measured in Hertz (Hz), refers to the number of times a display updates the image on the screen per second. Two of the most common refresh rates available in the market today are 60Hz and 120Hz. But is there a significant difference between these two, and does it really matter for your specific use case? In this article, we’ll delve into the world of refresh rates, exploring the differences between 60Hz and 120Hz, and helping you make an informed decision.
Understanding Refresh Rates
Before we dive into the differences between 60Hz and 120Hz, it’s essential to understand how refresh rates work. A display’s refresh rate is the number of times it updates the image on the screen per second. This is measured in Hertz (Hz), with higher numbers indicating more frequent updates. For example, a 60Hz display updates the image 60 times per second, while a 120Hz display updates it 120 times per second.
How Refresh Rates Affect Performance
The refresh rate of a display can significantly impact its performance, particularly in applications that require smooth motion and fast-paced action. Here are a few ways in which refresh rates can affect performance:
- Motion Blur: Lower refresh rates can cause motion blur, which is the streaking or blurring of fast-moving objects on the screen. This can be distracting and make it difficult to track objects in motion.
- Screen Tearing: Screen tearing occurs when the display shows multiple frames at once, causing a “tear” in the image. This can be particularly noticeable in fast-paced games or videos.
- Input Lag: Input lag refers to the delay between the time you input a command and the time it appears on the screen. Lower refresh rates can cause higher input lag, making it more difficult to react quickly in games or other applications.
60Hz vs. 120Hz: What’s the Difference?
Now that we’ve covered the basics of refresh rates, let’s dive into the differences between 60Hz and 120Hz.
