Do not look at the refresh rate of a TV. Not only is the advertised number false, but a 120Hz+ TV does not reduce the amount of motion blur in console games. Fake Refresh Rate Conversion Samsung Clear Motion Rate vs Sony MotionFlow vs LG Motion Clarity Index. With 120Hz, 240Hz, and even 600Hz, refresh rate gets a lot of attention in the marketing of new HDTVs. What it is and how it works is interesting, but why.
Samsung Clear Motion Rate vs Sony Motion. Flow vs LG Motion Clarity Index. ANSWERED QUESTIONS. What is the real refresh rate for Samsung UE3. F5. 50. 0? Could you add the refresh rates for the Panasonic TV models to the table?
We updated the tables in the main article to include them. LG is now advertising the refresh rate in terms of "Motion Clarity Index" and the TV show values of 2.
Hz and 4. 00 Hz for both 2. D and 3. D TVs. Is this an inflated number/marketing trick?
What is the real refresh rate present in LG TVs? Here is a table for you. Hz. 50. 10. 02. 00.
Hz. 40. 02. 00 Hz. What is the true refresh rate of a Samsung 7. CMR? The panel refresh rate of a 7.
CMR is 2. 40. Hz. We added a table above to do the conversion from Samsung's CMR to the real panel refresh rate. The table seems to have changed, LG 2.
Even high-end 4K TVs, like this Samsung JS8500, have a true refresh rate of at most 120Hz. Sarah Tew/CNET There's a. About Pogomix.net PC Gaming on an OLED TV Nick Bertke on December 10th, 2014.

This was an error that has been corrected. All of the series 6 from LG are 1. Hz. Could you please add a table for Toshiba as well?
I have a 4. 0TL9. G with a 2. 00. Mhz AMR.
I'd really like to see the refresh rate of the panel. The TV is fine for me - just wanna know if it's something better for a similar price, as I need to buy a new one soon : ). For clarification, the refresh rates listed, even if they are only of the 1. Hz variety are still misleading. Here's why. First off, there is no "LED" panel. All panels are LCD.
LCD/LED refers to backlight only. All consumer LCD TVs have a fixed maximum refresh rate of 5. Hz depending on whether or not they are PAL or NTSC systems respectively.
The 1. 20/2. 40 Hz specification is not the *panel* refresh rate, but instead the CPU's frame processing rate. That is, a 1. 20 Hz TV can process 1. Hz TV can process 2.
This internal refresh rate (I hate using that term for CPU processing) is of use only for frame interpolation on modern sets. Frame interpolation is where elements of at least two successive frames are received and analyzed by the TV's CPU for processing. On a 1. 20 Hz TV, the frame interpolation will work fairly well for 2.
FPS and 3. 0 FPS material as both fit into 1. For 6. 0 FPS material such as console games, computer display signals from a GPU, and certain broadcast signals, the frame interpolation used for motion blur reduction suffers from "hiccups". It is often referred to as the "hurry up and wait" effect where the motion smoothing will appear OK for a few frames, then suddenly de- sync for a couple of frames, and repeat the cycle. This is because there is no time to process the two key frames needed to go along with the third interpolated frame.
At 6. 0 FPS, on a 1. Hz TV, the TV can process two frames per refresh cycle, which does not leave enough time to inject an interpolated frame every other frame, which is necessary for motion smoothing to work properly. That is why TVs need processing at least three times the panel's refresh rate so that it can inject the interpolated frame in the time of each frame cycle. In order to avoid the de- sync issue, a TV would have to have internal processing of at least 1. Hz for 6. 0 FPS material to be displayed smoothly.
However, there are only 1. Hz and 2. 40 Hz TVs on the market (I ignore all those specifying higher Hz ratings because past 2. Hz there are no gains for frame interpolation). While a 1. 20 Hz TV can perform proper motion smoothing on 2. FPS material with virtually no de- sync problems, a 2. Hz TV is needed to perform motion smoothing without de- syncing.
In the case of a 2. Hz TV, the CPU in the TV has time to create three key frames and one interpolated frame from that data each cycle. In fact, true 2. 40 FPS (Hz) internal processing leaves headroom in case of any signal issues or errata in a frame. This is why the soap opera effect is so much more pronounce on a 2. Hz TVs than 1. 20 Hz TVs - with more time to process the key frames and interpolate a frame internally and headroom on top of that, the effect is much smoother and more consistent.
As for computer use, the reason the TVs won't accept a 1. Hz signal is because the panels are 6.
Hz maximum. The only possibility of that changing is if the TV is 3. D capable and accepts dual field 6. Hz stereoscopic 3.
D signals from the GPU or if the panel is upgraded to be a true 1. Hz (8. 3. 35ms) response time display. Samsung is unfortunately leading the market once again with its disengeuous specifications on its 4k UHD TVs.
Those TVs can process 1. Hz/FPS, but can only process 4. K (3. 84. 0x. 21. Hz/FPS. Despite Samsung's claims of HDMI 2. H6. 95. 0 TVs do not use true 4: 4: 4 chroma signaling. Instead they use 4: 2: 0 chroma subsampling, a method that is not an official HDMI 2.
HDMI 2. 0 as an "unsupported" spec. This is to allow the TV to receive 3. HDMI 1. 4 systems. It is no coincidence that n. Vidia used the same trick with their Kepler GPU drivers, which also send only 4: 2: 0 chroma signals to the TV/monitor instead of 4: 4: 4 chroma signals.
This is to reduce the bandwidth needed so an HDMI 2. Sadly, even the GTX 9. Vidia can still only net you a 4: 2: 0 signal into Samsung's H6. TVs even though those cards have true HDMI 2.
Hz. This is why nearly every review of the Samsung H6. It can display 1. Such is the misleading way of Samsung.
At the time of this post only Panasonic has a true 2. Display. Port 1. 2 port.
If you are intending to get a 4. K TV to use as a computer monitor, be aware that you will most likely need to wait until they start putting Display. Port 1. 2 connections onto their sets as that is the only way to guarantee a proper connection and color reproduction.
Anyway, bottom line is this: If you need motion smoothing for only 2. FPS (Blu- Ray) and 3.
FPS (DVD/OTA Broadcast), or 6. FPS Interlaced (DTV) material, a 1. Hz TV will suffice. If you intend to use 6. FPS (progressive scan) material with motion smoothing, you will need a 2.
Hz TV to avoid de- sync issues. For PAL regions, substitute 1. Hz/2. 00 Hz TVs for the 1. Hz and 2. 40 Hz specified for NTSC respectively. Thanks for this clarification! We agree with everything you said.
Could you add Philips PMR in the refresh rate conversion table? We did not add it in the main table because our majority of our visitors are coming from the United States and Philips does not use PMR here. But here it is. 5. Hz. 10. 02. 00. 10. Hz. 40. 08. 00. 20.

CMR, but is it 2. Hz or 3. 00. Hz? Could you please add a table for Sharp LCD TVs? It is only one producer of LCD panels with real 1. Hz, no motion interpolation.
Sharp does list the native panel refresh rate in their specs. It also lists the Aquo. Motion number separately. I have noticed the table above states that the LG motion clarity index rating of 2. Is there a way of verifying the figures with certainty?
This was an error in our table, and it is now fixed (thank you for pointing it out). The only way to be 1. TV and see if there is any soap opera effect (assuming that setting is turned on). What is the LG LED TV 3. D 5. 5UB8. 50. V refresh rate? What is Toshiba's Active Motion Rate? How much is 1. 00 Hz Active Motion Rate?
Toshiba's Active Motion Rate is not in the table because Toshiba's TVs for North America do not have that technology. Here are the Toshiba Active Motion Rate to real panel refresh rate conversions: 1.

Hz CMR in term of picture sharpness and clearness? Both a 2. 00. Hz CMR and 4. Hz CMR have a real panel refresh rate of 1. Hz, so their quality is about the same.
The larger CMR of 4. Hz is just a marketing gimmick that includes the video processing rate and backlight rate. What is the refresh rate for the lg lb. Please excuse the apparent impertinence of this question, but are you sure your table of refresh rate values for Panasonic in the "rest of the world" section is correct for 2.
Panasonic don't seem to have ever offered a 3. Hz backlight scan (ie equiv. Hz backlight scan. Is it possible that they do not understand the requirements for active 3. D, or has there been some sort of typo in your table perhaps? The WT6. 0/WT6. 5 is indeed listed as a 4.
Hz/3. 60. 0Hz backlight scan, so the table is correct. The store that you are looking at might not have that model though, or the country that you live in. From a quick search, it is available in the UK at least. Panasonic LED TVs do not use active 3. D, but passive 3. D; so there is no refresh rate requirement for 3. D. Are the new Toshiba Clear.
Scan refresh rates actual refresh rates? Clear. Scan is Toshiba's name for its motion interpolation technology, so yes. What does Samsung mean by having a tv like the UN6. F6. 30. 0 with a 1. Clear Motion of 2. Also the 6. 40. 0 is listed at 1.
Clear Motion of 4. This is confusing to me. All the 6 series have 1.
The truth about Ultra HD 4. K TV refresh rates. Even high- end 4. K TVs, like this Samsung JS8. Hz. Sarah Tew/CNET. There's a simple rule of thumb for companies that market electronics: When it comes to specs, a higher number is usually preferred. Sure, there are exceptions - - you want things like response time, load times and mobile device weight to be low - - but generally, more equals better.
It comes down to the "speeds and feeds" aspect that still dominates a lot of tech shopping: When you line up a bunch of similar TVs, phones, laptops or tablets, the ones with the higher numbers get the edge. Think about battery life, display resolution, screen size, processor speed, memory and storage capacity, to name just a few. Of course, the quoted number is often only half the story.
Consider the megapixel myth of digital cameras: a 1. Nor is a 4. K Ultra HD TV - - with a resolution of 3,8. HDTV with 1,9. 20x. K screen's resolution. Plenty of other factors, including color accuracy and contrast ratio (not to mention the quality of the video source) will affect the picture quality to a normal eye.
Then there's refresh rate. This spec refers to the number of times per second that a video screen is updated, with a higher number yielding a smoother, more natural- looking motion (up to a point). The baseline for this number was set back in the last century, with movie projectors hitting 2. Hertz, or Hz), and old standard- definition TVs set at 6. Hz in the US or 5.
Hz in many other countries. In the HD era, though, TV manufacturers started an arms race of sorts, ramping up refresh rates in increasing multiples to 1. Hz, and even eventually 2.
Hz. There was even a time where some plasma TVs were claiming, somewhat dubiously, a 6. Hz refresh rate of sorts: the "more equals better" situation again. So, now that we're in the post- HD 4. K TV era, we're clearly up to 4.
Hz, right? Or possibly 9. Hz? Not exactly. The fact is that nearly all of these new 4.
K TVs - - which now make up the increasing majority of all TVs priced over $1,0. US - - have, at best, a 1.
Hz refresh rate. Actually, many of the least expensive 4. K sets are 6. 0Hz, and none that we know about are 2. Hz. You may be asking yourself, what's with all the 4. K TV marketing that claims numbers of 2.
Well, they're fluff. Very carefully worded marketing fluff, in most cases. But does that mean those of you trading in a recent 2. Hz 1. 08. 0p TV for a bigger, sub- 2. Hz 4. K Ultra HD TV are actually downgrading your picture quality?
The answer, as always, isn't so cut and dry. What's refresh rate?
To recap: Refresh rate is how often a TV changes the image (also known as a "frame") on screen. With traditional televisions, this was 6. Hz." Some modern TVs can refresh at much higher rates, most commonly 1. Hz (1. 20 frames per second) and 2. Hz. We've covered this before, with 1. HDTVs, but it's the same idea.
But is this just yet another "more is better!" marketing ploy? Do the bigger numbers matter? Actually, they can: Higher refresh rates on LCDs and OLED TVs - - which, post- plasma, are pretty much the only two mainstream TV technologies left - - can help decrease motion blur. What's motion blur?
Glad you asked.. Your brain on blur All LCD and current OLED models suffer from "motion blur." This is where anything in motion, either an object moving on screen or the entire image (like when the camera pans), blurs and looks softer than if it was stationary. Geoffrey Morrison/CNET. Interestingly, this blur is largely created by your brain. Basically, your brain notices the motion, and makes assumptions as to where that object (or overall image) is going to be in the next fraction of a second. The problem with LCD and current OLED TVs is that they hold that image there for the full 6.
It's actually quite fascinating, but the details are beyond the scope of this article. I recommend checking out Blur.
Buster's great article for more info. The motion blur we're talking about here is caused by the television, on top of whatever blur the camera itself creates. Some people aren't bothered by motion blur.
Some don't even notice it. Others, like me, do notice it and are bothered by it. Refresh rate and beyond. Refresh rate itself is really only part of the solution. Just doubling (or quadrupling) the same frames doesn't actually do much for reducing motion blur.
Something else is needed. There are two main methods. The first is frame interpolation, where the TV itself creates brand new frames that are sort of hybrids of the frame that came before, and the one that comes after. This can fool your brain enough that it doesn't blur the image. Depending how aggressive the interpolation is, however, it can lead to the soap opera effect, which makes movies look like ultra- smooth reality TV. Some viewers like the effect, but it's generally hated by film buffs and others who pay close attention to image quality. The other is black frame insertion (BFI), or a scanning backlight.
This is where all or part of the backlight of the TV turns off (goes black). This effectively means the image doesn't "hold" in place, so your brain doesn't blur it. Do it poorly, however, and many people will see the image flicker.
The light output of the TV also drops as it's basically not outputting any light much of the time. Why 2. 40. Hz matters At a minimum, to do motion interpolation or black frame insertion, you need 1. Hz. Trying to do this with a 6. Hz TV means with a lot of content, the TV would be throwing away information.
Also, the backlight flashing would be visible to most people. Hz is better, as you can flash the backlight much faster (so it's less noticeable), and you can have more finesse with how you create the new frames (given that you have three new frames to create, as opposed to just one with 1. Hz). But at the very least, you need 1. Hz to really combat motion blur, which is good, because right now, that's the most you can get with a 4. K TV. All 4. K TVs on the market today (as of this writing), are 6. Hz or 1. 20. Hz. If that's surprising to you, and it likely is if you've shopped for a 4. K TV, it's because many manufacturers are being, shall we say, "creative" with their refresh rate claims (well, still being creative, this was and is common with 1.
TVs too). Sarah Tew / CNET. Ah, marketing Misleading specifications are a fact of life in the tech world, but that doesn't make them OK. Refresh rate is a real, measurable thing. If a company says "1. Hz" refresh, there's an expectation in my (and I assume, your) mind that the TV shows 1. Or at least, is capable of that. If it doesn't, if it's a 6.
Hz TV with black frame insertion for example, it may have similar motion resolution to some true 1. Hz TVs, but it's not actually 1. Hz. So many (most?) of the refresh claims you see on 4. K TVs are likely somewhat misleading. None are more than 1. Hz, despite what their numbers claim, and many are just 6. Hz. Here's the best way to read refresh specs: If it uses any sort of modifier ("Tru.
Motion 2. 40. Hz"), or doesn't explicitly say it's the panel refresh, it's probably not. The few companies that disclose the actual panel refresh information on their websites are quite clear what the panel is doing, and what the backlight and processing assistance does.

Motion LG, like several other brands, uses "Hz" but qualifies it with "Tru. Motion," which it describes as: "Tru. Motion reflects the benefits of our detailed backlight scanning and enhanced frame rates to reduce blur and yields (sic) crisper details." So it's all the methods above. It doesn't list just the panel framerate in Hertz anywhere, unfortunately. So we asked. According to LG, the UF7.
Hz, while the UF7. UF8. 50. 0, UF9. 50. Hz. Panasonic: Image Motion or Backlight Scanning Most of Panasonic's models feature some kind of BFI or scanning, but its top 4. K models are listed in the specs as actually having 2. Hz refresh. Elsewhere, however, it describes it thus: "Image Motion Technology uses high quality frame creation and advanced back light scanning to ensure fast action scenes are always clear." Panasonic has updated its website to list accurate refresh rates, and confirmed to us the CX6. Hz refresh, while the CX6.
CX8. 00, CX8. 50 series have 1. Hz. Sharp: Aquo. Motion Sharp gets multiple bonus points here for listing the "Aquo. Motion" rate, and the panel's native refresh and clearly describes how it works: "Aquo. Motion, Sharp's backlight scanning technology, multiplies the effective refresh rate to hit you with all the power that fast- moving sports and movies can deliver." Most of its 4. K models are 1. 20. Hz natively, whereas some of the smaller and less expensive models are 6. Hz. Samsung: Motion Rate Samsung is more upfront than it used to be about this.
Its 4. K TVs feature "Motion Rate 2. Hz") which it describes thus: "Enjoy our best moving picture resolution at Motion Rate 2. Here's a diagram.
Samsung. As it explains, "Clear Motion Rate is a motion clarity standard put forth by Samsung Televisions in order to replace what is commonly known as the 'refresh rate' associated with many televisions." It includes motion processing and backlight scanning into one number that might allow you to compare Samsung models with each other, but is meaningless compared to other TVs. As far as Motion Rate 2.
K TVs, it's a 1. 20. Hz refresh rate panel with some sort of backlight scanning or BFI.
