Clear Motion Rate (CMR) vs Refresh Rate
Whether or not people understand the rationale behind the refresh rates of LCD monitors, they believe or think that higher refresh rates mean more clarity in pictures or sharpness of picture on the screen. The refresh rates of an LCD explain how many times an image is drawn on the monitor every second. We have TV’s with refresh rates of 60Hz, 120Hz and even 240Hz. So does it really mean that higher the refresh rates of a TV, the sharper or clearer it is? And now there is another term called Clear Motion Rate to confuse the consumers further. This is a recent term that has been introduced by electronics giant Samsung. There are not many who understand the difference between Clear Motion Rate and Refresh Rate, and this article attempts to explain this difference.
Refresh Rate (Hertz)
All display monitors need to be refreshed many number of times every second. This refresh rate is expressed in hertz, and the number implies that the image is redrawn that many times in a second. The old industry standard was 60 Hertz, but there has been advancement in technology and now it is common to have TV’s with refresh rates of 120Hz and even 240Hz. TV’s with higher refresh rates flicker much less than TV’s with low refresh rates; also, the images are often sharper and clearer with TV’s of higher refresh rate. The human eye cannot detect a blur as the image is redrawn too quickly. This difference is all the more visible in programs where objects move at a fast rate such as sports or car racing. However, with most TV companies switching over to 120Hz refresh rate, this motion blur has more or less been controlled.
Clear Motion Rate (CMR)
CMR or Clear Motion Rate is a new concept introduced by Samsung that measures the capacity of an LCD to display fast moving objects smoothly. While there was only the refresh rate that decided the smoothness of images in a fast paced program, Samsung’s CMR takes into account backlight technology and image processor speed in addition to the refresh rate to decide motion clarity. This motion clarity means that a viewer can clearly see the name of the player and his jersey number, even when he is moving at a high speed, during NFL matches.

What is the difference between Refresh Rate and Clear Motion Rate (CMR)? • Refresh rate is the industry standard for judging the motion clarity of an LCD monitor, and higher the refresh rate, the sharper and clearer are the images as the image is redrawn 120 times per second if the refresh rate is 120 Hz • CMR is the measure of motion clarity that takes into account backlight technology and image processor speed in addition to refresh rate • While refresh rate is a factor in deciding motion clarity, it is not the only factor, and this has been proved with CMR. |
Thank you!!! This makes explaining this to my customers much more credible than just saying “It’s just marketting jargon”
Much appreciated.
So, just to be clear, there’s no way to “translate” Hz to Clear Motion Rate???
Like, if a TV has a clear motion rate of 120, could that be considered as being 120 Hz?
from what i know they double the frames n few more things,,, so roughly 120 CMR will be 60 Hz refresh rate..
Wrong!!!it’s 240!!!Because now they have 1200 cmr,hence the clarity and the price of the new cmr TVS!!!
So many “!”s. It makes you look mean and ignorant
MY 85 INCH sAMSUNG IS THE BEST tv out there and the cmr AND motion rate is incredible,you see no blur on anything,I hate people that don’t do any research.4KUHD IS THE FUTURE OF TV WITH UPDATES TO THE TV EVERY YEAR,3D IS GREAT,YOU CAN’T GO WRONG.
That was… A really good comment. Idk exactly which TV you have but Samsung TVs are really good. I have a personal policy of not early adopting TVs but when the technology has been out there for a few more years with more content being made, then I’ll b on that bandwagon
tHAT’S ONE THING ABOUT THIS TV you can upgrade,sadly you have to pay for it but it is a 4kUHD tv,I got it on sale and for a great price,you would like it,the picture quality is unlike I have ever seen.
Yes, but mine is still bigger than yours!. and my dad can beat your dad up!. so there.
Hey d bag my Dad passed away your lucky punk,payback grow the f up!!!!!!!!!!i’M a state employee and idiot’s like you have no class or a life and certainly no MONEY OR A JOB,LOSER!!!!!!!!!!!Go pop your dad)))))
DAN, you forgot to mention that I do not have a LITTLE tv like you have! LOL. that and the grandiosity as you pretend to have about your life and yourself.
I think he was joking around son. He also could have looked at your pic and seen how damn old you look and then guessed that he’s passed away.
Ooohhh my! I have a 110″ and it is truly the best than everybody put together tv, and its much better than Daniels tv, and I hate you for thinking that yours is the best.
Putting WHAT THE CMR is in your post would have been helpful, without that your useless.
What a load… this is just marketing jargon. “Clear Motion 120” means it’s 60hz. Otherwise, they would call it “Clear Motion 120hz”. Samsung is multiplying the true refresh rate by other non-refresh rate factors, for example the number of processors or the LED backlight.
They also include other stuff that they use to try to mask the issues of a low refresh rate, like motion blurring, or (insert latest image processing term here). Then they make some guesses and say, “you know what, it kind of looks like it’s 120hz, right? Lets call it Clear Motion 120 then.”
The true refresh rate is still the most important spec. And the backlight dimming has to be the same speed as the refresh rate, so no, you can’t multiply 60*2 to get 120hz… the picture and backlight are in sync, so it’s still 60hz. Image processing also doesn’t change the refresh rate of the screen. It only applies different filters or algorithms to the image to cover up any flaws like blocking, stuttering, latency, ghosting, etc.
Thank you, and actual answer to the original question.
