Dynamic motion rate 120 (DMR 120) is a term used by some television manufacturers to describe the 120Hz processing capabilities of their HDTVs. DMR 120 is designed to reduce motion blur and improve picture quality during fast-action scenes.
Some manufacturers use other terms to describe their 120Hz HDTVs such as TruMotion 120Hz from LG and Clear Motion Rate 120 from Samsung.
How DMR 120 Works
DMR 120 works by doubling the number of frames per second that are displayed on the screen. Most movies and television shows are filmed at 24 frames per second so DMR 120 effectively doubles that to 48 frames per second.
Some manufacturers use other terms to describe their 120Hz HDTVs such as TruMotion 120Hz from LG and Clear Motion Rate 120 from Samsung.
The DMR 120 technology is designed to reduce motion blur and improve picture quality during fast-action scenes.
To understand how DMR 120 works it is first necessary to understand how the human eye perceives motion.
The human eye is relatively slow at perceiving motion. This is why movies and television shows are displayed at a rate of 24 frames per second – it is the minimum frame rate that the human eye can perceive as smooth motion.
However the human eye can perceive a limited amount of blur during fast-motion scenes. This is why DMR 120 is designed to display each frame on the screen for a shorter period of time than traditional HDTVs.
In other words DMR 120 uses a higher frame rate to reduce the amount of motion blur that is perceived by the human eye.
The Benefits of DMR 120
The primary benefit of DMR 120 is that it can improve the clarity of fast-action scenes. This is especially true for sports broadcasts and action movies.
Another benefit of DMR 120 is that it can reduce the amount of image tearing that is seen on traditional HDTVs. Image tearing occurs when the video signal is not in sync with the refresh rate of the HDTV. This can cause the image to appear “torn” or “jagged” around the edges of objects in fast-motion scenes.
DMR 120 is designed to reduce image tearing by using a higher frame rate and shorter frame times. This allows the HDTV to better keep up with the video signal which can lead to a smoother image.
Not all 120Hz HDTVs are Created Equal
It is important to note that not all 120Hz HDTVs are created equal. Some HDTVs use lower-quality panel types that are not capable of displaying the full 120 frames per second.
Other HDTVs use lower-quality image processing that can introduce artifacts into the image. These artifacts can degrade the overall picture quality even if the HDTV is capable of displaying a higher frame rate.
When shopping for a 120Hz HDTV it is important to look for a model that uses a high-quality panel and high-quality image processing. This will help to ensure that you get the best possible picture quality.
DMR 120 vs. Motion interpolation
It is also important to note that DMR 120 is not the same thing as motion interpolation. Motion interpolation is a processing technique that is used to insert artificial frames into the video signal.
This can cause the image to appear “smoother” but can also introduce artifacts into the image. Motion interpolation is sometimes also called ” frame insertion” or ” Soap Opera Effect.”
DMR 120 does not use motion interpolation. Instead it doubles the frame rate of the video signal to reduce motion blur.
Should You Use DMR 120?
The decision of whether or not to use DMR 120 depends on your personal preferences. If you watch a lot of action movies or sports then you may appreciate the improved clarity that DMR 120 can offer.
If you are watching a lot of movies or TV shows that are filmed at 24 frames per second then you may not notice a significant difference with DMR 120.
It is also important to note that DMR 120 can introduce some image artifacts depending on the quality of the HDTV.
If you are concerned about image quality then you may want to disable DMR 120. You can usually do this through the menu system of your HDTV.
Ultimately the decision of whether or not to use DMR 120 is a matter of personal preference. If you watch a lot of action-packed content then you may benefit from the use of DMR 120.
If you are more concerned about image quality then you may want to disable DMR 120.
What is the difference between a 120 Hz refresh rate and a standard 60 Hz refresh rate?
A 120 Hz refresh rate means that the display refreshes 120 times per second while a standard 60 Hz refresh rate only refreshes 60 times per second.
This means that 120 Hz displays can show twice as many frames per second as 60 Hz displays.
How does a 120 Hz refresh rate improve motion resolution?
A 120 Hz refresh rate improves motion resolution by reducing motion blur.
This is because the display refreshes more quickly so each frame is displayed for a shorter period of time.
This reduces the amount of time that a given frame is displayed on the screen which reduces motion blur.
How does a 120 Hz refresh rate improve image quality?
A 120 Hz refresh rate improves image quality by reducing image artifacts.
This is because the display refreshes more quickly so each frame is displayed for a shorter period of time.
This reduces the amount of time that a given pixel is displayed on the screen which reduces image artifacts.
