You must have heard about the TV refresh rate, 60Hz or 120Hz. But do you know what does it mean and how does it affect the picture on your television? Well, if you don’t and are curious to know, we can help. This article has deep insights regarding the TV refresh rate and related information.
You’ll learn about what TV refresh rate is and what refresh rate is good for a TV. You can use this information whenever you’re buying a new television and make a better choice. If you’re interested, read this article in full.
What is a TV Refresh Rate?
The TV refresh rate is the measure of how many times the TV redraws the image on the screen in a second. The unit of its measurement is Hertz. It is abbreviated as “Hz”. Most of the TVs have 60 as refresh rate.
But TV manufacturers do not list this number on the television. Many manufacturers use different techniques and technologies such as the black frame insertion and claim a higher number. Most of the time, they do not even justify the claims, and sometimes they do.
Movies are generally filmed at 24 Hertz or 24 frames per second. Live shows are filmed at 30 or 60 frames per second. The reason for higher frames per second is to minimize the motion blur in TV technologies. Motion blur is when the image gets softened when the object is moving or is in motion.
What is a good refresh rate for a TV?
Theoretically speaking, 120Hz means that the image will be displayed double the times as compared to the refresh rate of 60Hz. This is why many people believe that a television with a good refresh rate of 120 Hz is better than the one with 60 frames per second.
According to the research, a television with a frequency of 120 Hz doesn’t mean that the motion blur will be lesser than its 60 Hz counterparts. This means that a normal rate of 60 Hz is good for televisions. The refresh rate depends on the type of content you are watching on the television.
If you play many games on your TV and watch high and fast-paced movies, you might need a 120Hz TV for better picture quality. If you are not into gaming, then it’s better to stick to a 60 Hz model. It would also save you money.
Video Frame Rate vs. TV refresh rate
While video frame rates and TV refresh rates sound almost the same, here are some points that make them different from each other.
A video frame rate is represented and measured in frame per second (FPS).
A TV refresh rate is measured in Hertz (Hz)
Frame rate – A higher frame rate helps in reducing choppiness, especially while watching fast-paced movies or series or while playing video games. FPS will determine how smoothly the picture is getting displayed on the screen.
Refresh rate – A high refresh rate will improve motion rendering, i.e., motion blurring.
Frame rate – Most of the movies are shot in 30 FPS or even lower than that. This means that a frame rate of 60FPS is going to be of no use.
Refresh rate – Most of the time, refresh rates aren’t even noticeable.
When displaying 120 FPS content
Content at 120FPS or frames per second is quite hard to find unless it’s a AAA game title. If your TV supports 120Hz input and you have connected a console with a similar configuration, the performance can be impeccable.
The picture at 120fps will be clearer. It remains on the screen for less time than that of a 60fps picture. This causes a phenomenon known as persistence blur, which delivers a better image and prevents it from blending.
Different refresh rates from different sources
Different TV brands and companies have different use different technology to increase or enhance the refresh rate. Let’s have a look at them:
LG – Tru Motion
Nowadays, LG represents its refresh rates in this manner.
Tru Motion 240 (with 120Hz refresh rate)
Tru Motion 120 (with 60Hz refresh rate)
Motion Rate – Samsung
Motion rate is the term that Samsung uses specifically for it’s 4K TVs. It is two times the native refresh rate. This means that a Motion rate of 240 will be a good refresh rate of 120 Hz. In the case of low-priced televisions, Samsung has a Motion-rate of sixty for a 60Hz native refresh rate.
Slow Motion XR – Sony
In the latest models, Sony doesn’t indicate some number with the term Slow Motion XR. In its older models, slow-motion XR 240 will indicate a 60Hz native refresh rate. Motion flow-XR 1440 indicates it has a 120Hz refresh rate (native)
Clear Frame – Toshiba
High-end Toshiba TVs have a 120Hz refresh rate. Other TVs represent a lower refresh rate of 60Hz.
Sharp – AquoMotion
AquoMotion is the term that Sharp uses for its refresh rates and is not greater than a 60Hz.
Clear Motion Index – TCL
All the TVs by TCL have a 60Hz refresh rate except for its highest-priced model.
The 75 inches 6 series TCL television has a refresh rate of 120Hz.
All the TV manufacturers used these terms as a marketing gimmick. They use them, especially for those people who don’t understand these terms.
How to get the best results
To get the best results in terms of refresh rates, you need to tweak some settings. It may differ with TV brands, but you can follow the below settings. These settings will help you achieve a judder-free or shake-free image.
For Samsung TV: Usually, in Samsung TVs, this setting is automatically enabled. However, a 24 FPS video can shake via 60i and 60p. And for 1080i or 480i video content, you can:
- Visit the menu settings
- Then go to the picture
- Go to picture options and then enable Film Mode
For Sony TV:
- Visit the Menu Settings
- Go to Picture and Display
- Find Picture Adjustment
- Now tweak the ‘MotionFlow’ setting to ‘True Cinema.’
- Also, set ‘Cinemotion’ setting to high.
For LG TV:
- Visit the menu settings.
- Then find picture
- Then go to picture mode settings.
- You now have to set the ‘Real Cinema’ setting to ‘On.’
For Other TVs:
- You need to find settings.
- Then go to ‘Auto Motion Plus.’
- You need to change the ‘Auto Motion Plus’ to ‘Custom.’ You can do it by moving both sliders towards 0
Following the above steps in most TVs, you can achieve a shake-free image.
You can think of the refresh rate as the factor determining how well the picture is displayed on the screen. Usually, the more it is, the better is the image quality. Now, as you know what refresh rate is and what’s ideal for a good TV, you can make a good informed decision while buying one.
