When buying television I just found out that some of you often care about the frequency at which a television scans. Here, you along with you to find out about the true frequency of scan on TV? What do they mean? What is the effect? Through this article for reference offline!
1. What is the actual refresh rate on the television?
Before I learn about the actual scan frequency, I will briefly introduce the frequency on TV for you to understand better.
The TV’s refresh rate (also known as its motion ratio) is the speed at which the TV displays a new image (calculated within 1 second). The unit of frequency sweep is called Hz.

In the same firm, the higher the scan frequency, the smoother and smoother the moving images.
The TV’s actual refresh rate is the number of frames per second controlled by the TV’s background. Put simply, this is the number of characteristic frames that your eyes can see in a second.
For example, a television with a real refresh rate of 120 Hz means that it can project 120 “different” frames within 1 second.
The number of frames the eye can perceive in 1 second
– Unit of measurement of actual sweep frequency
Similarly, the actual refresh rate also has a measurement unit of Hz based on the number of frames per second that the human eye can see displayed on the screen.
2. What is the actual refresh rate on the television?
This refresh rate will boost when you watch fast-moving scenes on TV (action movies, sports, racing games, …).
At this time, the higher the frequency of a television set, the smoother the view will be, the more “eyesight” will be.
Real refresh rate helps improve the smooth quality of the picture
In fact, with most flat-screen TVs currently available on the market, the lowest true frequency is found 50Hz, higher lines are about 100Hz, 120Hz or 200Hz.
3. Scanning frequency parameters on popular TV today
Television companies often avoid referring to the actual frequency of the scan, but instead use separate names for the frequency at which they are scanned (Example: Motionflow ™ XR 1200Hz), which are called “virtual sweep frequency”.
So, instead of using the actual scan frequency, each TV brand has a very attractive sounding name for its own virtual sweep frequency (image index): Samsung calls Motion Rate technology, LG called TruMotion, Sony called Motionflow, Panasonic called Image Motion, …

The results of these technologies do not change the actual scanning frequency of the television, but change the “feel” of the user when looking.
