When it comes to buying a new TV, there are several factors to consider, from screen size and resolution to smart features and connectivity options. However, one often-overlooked aspect that can greatly impact your viewing experience is the refresh rate. In this article, we’ll delve into the world of refresh rates, exploring what they are, how they work, and why they matter.
What is Refresh Rate on TV?
The refresh rate of a TV refers to the number of times the screen updates the image per second. It’s measured in Hertz (Hz) and is usually expressed in values such as 60Hz, 120Hz, or 240Hz. A higher refresh rate means that the TV can display more frames per second, resulting in a smoother and more realistic image.
To understand how refresh rates work, let’s take a step back and look at how TVs display images. A TV screen is made up of millions of tiny pixels, which are arranged in a grid to form the images you see. When you watch a movie or TV show, the TV is actually displaying a series of still images, known as frames, in rapid succession. The refresh rate determines how often these frames are updated.
How Does Refresh Rate Affect Picture Quality?
A higher refresh rate can greatly improve picture quality, especially in fast-paced content such as sports, action movies, and video games. Here are a few ways that refresh rate can impact your viewing experience:
- Reduced motion blur: When a TV has a low refresh rate, fast-moving objects can appear blurry or streaked. This is because the TV is not updating the image quickly enough to keep up with the motion. A higher refresh rate can reduce motion blur, making it easier to follow the action.
- Improved clarity: A higher refresh rate can also improve the overall clarity of the image. By updating the image more frequently, the TV can reduce artifacts such as judder and stutter, resulting in a smoother and more realistic picture.
- Enhanced gaming performance: For gamers, a high refresh rate is essential for a responsive and immersive experience. A TV with a high refresh rate can reduce input lag and improve motion clarity, making it easier to react to fast-paced action.
Types of Refresh Rates
There are several types of refresh rates available on modern TVs, each with its own strengths and weaknesses. Here are a few of the most common types of refresh rates:
- 60Hz: This is the most common refresh rate found on budget TVs. While it’s sufficient for casual viewing, it can struggle with fast-paced content.
- 120Hz: This is a mid-range refresh rate that offers improved motion clarity and reduced motion blur. It’s a good option for those who want a smoother picture without breaking the bank.
- 240Hz: This is a high-end refresh rate that offers exceptional motion clarity and reduced motion blur. It’s ideal for gamers and those who want the best possible picture quality.
- Black Frame Insertion (BFI): Some TVs use a technology called Black Frame Insertion (BFI) to improve motion clarity. BFI works by inserting black frames between the regular frames, which can help to reduce motion blur and improve the overall picture quality.
Refresh Rate Technologies
In addition to the types of refresh rates mentioned above, there are also several refresh rate technologies that can enhance picture quality. Here are a few examples:
- Motion Rate: This is a technology developed by Samsung that uses a combination of backlight blinking and image processing to improve motion clarity.
- MotionFlow: This is a technology developed by Sony that uses a combination of backlight blinking and image processing to improve motion clarity.
- Clear Motion Rate: This is a technology developed by Vizio that uses a combination of backlight blinking and image processing to improve motion clarity.
How to Choose the Right Refresh Rate for Your TV

Is a Higher Refresh Rate Always Better?
While a higher refresh rate can offer several benefits, it’s not always better. For example, if the content being watched is not optimized for a higher refresh rate, the benefits may not be noticeable. Additionally, a higher refresh rate can also increase the power consumption of the TV, which may be a concern for those who are environmentally conscious or have limited power supply.
Furthermore, some TVs may use motion interpolation to create additional frames, which can sometimes result in the “soap opera effect.” This can make the image look unnatural and overly smooth, which may not be desirable for some viewers. Therefore, it’s essential to consider the specific needs and preferences when choosing a TV with a higher refresh rate.
Can I Upgrade My TV’s Refresh Rate?
In most cases, it’s not possible to upgrade a TV’s refresh rate. The refresh rate is usually determined by the TV’s hardware and is fixed at the time of manufacture. However, some TVs may offer features such as motion interpolation, which can create additional frames to simulate a higher refresh rate.
It’s also worth noting that some TVs may offer a “motion rate” or “effective refresh rate” that is higher than the actual refresh rate. This is usually achieved through motion interpolation or other technologies that create additional frames. However, the actual refresh rate remains the same, and the benefits of a higher refresh rate may not be fully realized.
What is Motion Interpolation, and How Does it Relate to Refresh Rate?
Motion interpolation is a technology used in some TVs to create additional frames between the actual frames displayed on the screen. This can help to simulate a higher refresh rate and reduce motion blur. However, motion interpolation can sometimes result in the “soap opera effect,” which can make the image look unnatural and overly smooth.
In terms of refresh rate, motion interpolation can help to create a smoother viewing experience, but it’s not a substitute for a higher actual refresh rate. While motion interpolation can create additional frames, it’s not the same as displaying more actual frames per second. Therefore, when choosing a TV, it’s essential to consider the actual refresh rate rather than relying solely on motion interpolation.
How Important is Refresh Rate When Choosing a TV?
The refresh rate is an important factor to consider when choosing a TV, but it’s not the only factor. Other aspects such as resolution, contrast ratio, color accuracy, and smart TV features should also be taken into account.
