Update 2017/08/10: With the transition to the 1.1 test bench we have changed the way we are measuring response time, to more accurately represent perceived blur.

Motion blur that you see on TVs influences how blurry fast movement appears to be on the screen. For the most part, motion blur manifests as a trail on moving objects and is of particular importance for sports and video games. If you enjoy watching either of those things, it’s important to get a TV with minimal blur.

When evaluating motion blur, we photograph the appearance of blur on the TV and then test for pixel response time.

When it matters

For the majority of TVs, motion blur is really only a potential problem with sports and video games, because of the quick movement inherent to both. With movies and regular TV, you will almost never perceive motion blur other than that which is included in the video, due to the low frame rate and the slow shutter speed of the camera.

Too much motion blur is very noticeable, and can ruin the look of movement on a TV – nobody wants a long trail following a moving object. Beyond those TVs that clearly have way too much blur, the amount of blur that a person will find acceptable is subjective. Some people are much more sensitive than others. 

Our tests

Pursuit Camera TestMotion blur picture setup

To provide an idea of the way motion looks on the TV, we use a rail-mounted pursuit camera to take a photo of our logo while it moves across the screen. The resulting photo represents what you can expect your eye would see while watching a moving object, and while it’s not a perfect representation, it’s at least a fairly useful example.

In the test, our logo moves across the screen at a speed of 960px per second, and at a frame rate of 60 fps. We slide our camera along the rail at the same speed as the logo, and take a picture with a shutter speed of 1/15 of a second, to capture all artifacts.

To validate that our camera goes at exactly the same speed as our logo, we are using temporal tick marks placed just below the logo. This technique was invented and proposed to us by Mark Rejhon of Blur Busters, a website dedicated to the reduction of motion blur.

You can test your own screen using our test pattern. If you follow our logo with your eyes, you will be able to compare it to our test results. Alternatively, you can find a wide variety of motion tests over at TestUFO.com.

Score distribution

Response time is the amount of time it takes a TV’s panel to change from one color to another, and it’s a pretty big part of the blur we see on TVs. With a long response time, the pixels can’t quite keep up with moving objects, and so you can see a lengthy trail of blur following behind them. Above, you can compare a long response time (left) to a short response time (right), and you can see that the difference is a pretty big one.

To test for response time, we use an array of photodiodes connected to an Arduino Due board, which is itself connected to a computer through USB, to record how quickly a TV is able to make transitions between different shades of gray.  Every shade corresponds to a different level of luminance output, and so when a TV switches from one shade to another, the screen’s luminosity must also change. The amount of time it takes a TV to make this change in luminosity is the response time, which is measured in milliseconds.

Once we have performed this evaluation for each of the transitions we test, we take the times for each completed transition and average them out, which gets us our global response time number. Note that some transitions may have a lower response time than the average we list, meaning less blur for those changes, and others might take a good deal more time, creating more blur in those cases.

TV response time - transition between 20% gray and 80% gray

80% Response Time

What it is: How quickly pixels can reach 80% of a full transition from one color to another.
When it matters: Fast movement.
Good value: < 8 ms
Noticeable difference: 4 ms
Score distribution

The methodology used to determine the 80% Response Time is the same as for the 100% Response Time, as described in the previous paragraphs.

In the chart above, a transition between 20% gray (dark gray) and 80% gray (light gray) begins at the vertical red line and is complete at the vertical green line. The vertical orange line represents the moment when screen luminosity has completed 80% of the transition to its target state, which in this case represents a 68% gray level (20% + 0.8*(80%-20%) = 68%). The luminosity level of 20% gray is represented by the horizontal red line at the left, the luminosity level of 68% gray is represented by the horizontal orange line, and that of 80% gray by the horizontal green line at the right. The time it takes the luminosity to change from the red to the orange line represents the duration of the 80% response time, and from the red to the green line represents the length of the 100% response time. The 80% response time is a good indication of the smoothness of movement, with shorter response times making movement clearer and longer response times making movement smoother, while also adding short but apparent trails to moving objects. The 100% response time is a good indication of how long the faint trails following moving objects will appear.

You can see that the transition between shades/luminosities surpasses the level required by the 100% response sooner than our response time measurement would indicate. However, this is a temporary overshoot, and the transition is only considered complete when the luminosity is stable at the new level. Tests done prior to 2017 considered this overshoot separately from the response time, but overshoot is perceptually very similar to a transition being incomplete, with both phenomena adding visible trails behind moving objects. Overshoot shows trails that are lighter than the background behind moving objects, while a slow transition adds trails that are darker than the background.

Additional information

Elements of motion blur

Motion blur is created by several things:

  • Response times, which represent how long it takes a TV’s pixels to change from one color to another. Longer times equate to longer blur trails on moving objects.
  • Frame time, which represents the amount of time for which a frame is displayed on the screen. The longer the frame time, the more blur you will see. See more information about this manifestation of motion blur here.
  • Blur within the video itself. This results from the on-camera action outpacing the camera’s shutter speed. Cinematographers usually keep this kind of blur in mind and will account for it when planning shots for the movie or show. The result will usually be that you don’t even register that the blur is there.

How to get the best results

Most elements of motion handling are static. For example, response times can’t be changed through settings, and so those elements of motion blur cannot be improved.

If you have the option to do so, watching media with a higher frame rate will help you avoid blur. Some TVs may also have a couple of settings that can improve other elements of the motion blur, though you should be aware that they each have their own downsides. We list those settings below.

Related settings

  • Motion interpolation enhances the frame rate of video by creating and inserting transitional frames between the original video’s existing frames. This reduces frame time and creates a smoother look overall, but some find the result undesirably similar to the look of a soap opera. What’s more, since there is no improvement to the response time of the pixels, the length of the trail on moving objects doesn’t change. We talk more about the pros and cons of motion interpolation here.
  • Some TVs have the option to introduce backlight flickering, or insert black frames, in order to shorten frame time and clarify movement. This also has the effect of dimming the maximum luminosity, though. As with motion interpolation, this does not affect response time, so the length of the trail on moving objects does not change. See more information about the effects of flicker here.

Other notes

  • By nature of the technologies, LCD panels (LCD and LED TVs) have relatively long response times, and OLED panels have much shorter ones.
  • A video with a higher frame rate will only have less blur than an identical video with fewer frames if the TV’s refresh rate is capable of matching that frame rate (ex: a 120 hz video on a 120 hz TV, not on a 60 hz TV).
  • Similarly, a TV with a 120 hz refresh rate will not have less blur than a 60 hz TV if the video’s frame rate is not also higher than 60 hz. With 60 hz video on a 120 hz TV, the video signal will still only be 60 fps, which means the frame time has not changed. The same applies for 24 hz and 30 hz on TVs with higher maximum frame rates.
  • Refresh rate also does not have any effect on response time.
  • It’s impossible to compare response times listed by different manufacturers and reviewers without knowing the testing methodology. We test several gray-to-gray transitions and present an average, but some manufacturers and reviewers will only list the shortest response time the screen is capable of, or they might test the time it takes to go from one shade to another, and then back. Unless you can compare the entire methodology, the results won’t match up in a fair way.


Motion blur makes fast movements look less clear, which can be an annoyance for sports fans and gamers. If you watch either of those things, it’s important to get a TV with minimal blur. To get a good idea of how much blur TVs have, we test them for their pixel response and overshoot times.

Your best bet for getting a TV with little blur is to find a model with low response time. You can also help reduce the amount of blur you perceive by watching higher-frame-rate videos, or by enabling motion interpolation or backlight flickering features. Just remember that enabling these sorts of extra features can introduce other issues to the video.

Questions & Answers

I would just like to say thank you. I have been fixated on the issue of motion blur in game mode for some time and this site is just awesome. As you say, most review sites simply state the motion performance with "smooth motion" engaged. Separately, they list the input lag, which is measured in game mode with motion interpolation disabled. I have seen so many sites say one TV or another is great for gaming because it has low input lag. That's great, but if the motion blur is there, it makes for a bad experience to me. Anyways, I appreciate it. Keep up the good work!
Thanks for the feedback! We are glad you find it useful.
Hey I have a question. I'm looking to purchase a new TV for when the PS4 comes out. I am not a hardcore gamer. Anyway, the two models that I'm considering are either the Panasonic S60 or Samsung F5300. I read your comparisons, but I'm not sure if anyone like me will notice those differences in input lag and things. Anyway, would you recommend one over the other? I usually play games like Call of Duty and Battlefield.
They are very similar, and you will be happy with both. Picture quality-wise, the S60 is better than the F5300 (except for motion blur). The blacks are deeper and there is less reflection. Also, the input lag is better. It cannot get as bright, though. I would go for the S60 if you can find one; they are mostly out of stock now, and they won't get back in stock because Panasonic are ceasing production of plasma TVs. If you can't find one, the F5300 is still a great TV and won't disappoint you.
We purchased a Samsung UN60H7150 240hZ TV and are very disappointed in the way sports, specifically football looks. The fast motion looks blurred, and we even noticed the ball would disappear while it was in the air! Is there any way to make this watchable, or are we going to have to live with this?
If you have Auto Motion Plus enabled, try disabling that and seeing if that helps. This is the feature that is making the ball disappear in midair. If that doesn't get the result you want, try setting Auto Motion Plus to "Custom" and then enabling LED Motion and turning deblurrer/dejudder off. Keep in mind that LED TVs having a little bit of motion blur is normal.
Really cool site, but i have to reply to the above comment. I couldn't disagree more. I used to own plasma TVs and I loved it. I then went with projector for a while and then decided it was time for something else. First I had this Toshiba LED, and while the picture quality was amazing, the blur made it impossible for gaming. Right now I have the Sony W829B and motion blur-wise it is probably the best an LED will get, and picture quality-wise... outstanding. I have directly compared it on the spot to a Panasonic VT60, and for me, the Sony clearly won in every way. The VT60 also looked dim, while the Sony was incredibly bright but still very VERY nice to look at. So I have to kindly disagree with that what you said. :)
No problem, and thanks for sharing your opinion. The VT60 is indeed very dim compared to any LED TV.
I want a new 55' TV, mainly for playing PS4. I don't notice input lag much, but if it is awful I do notice it. The thing is, I really hate motion blur, so I don't know which TV will be the best for me, The Samsung H7150, the Sony W800B with the Impulse mode, or the LG LB6300. I have had a bad experience with LG and motion blur in the past. I hope you can help me with this issue?
The Sony W800B with Impulse mode is the best you can get in terms of motion blur. You need a somewhat dark room, though, because it doesn't get very bright. Flickering can also be an issue for some people.
It seems like you have changed many of the 2015 tv's motion blur ratings with some sort of new system, would you mind giving us a layman's type explanation of the new ratings and how it affects watching sports on all the tv's? Thanks for the good work. I really like checking out all the reviews.
We will update our article soon to explain it in-depth. In short, the new score is now only based on the response time and overshoot of the pixels. Basically, we now measure how long it takes a pixel to transition from one color to another (how fast they can switch). You can click on the response time numbers to see the actual data that we measured, and see all transitions.
As for how it translates to what you actually see, it is basically the length of the trail. In our pictures, the trail on the left side of our logo correspond mostly to the 0% to 80% transition in our charts. The other transitions can be seen in our pictures, but it takes a trained eye. We probably need to update our motion blur pattern to have one that shows better more transitions than just the 0 to 80.
In my thorough shopping experience, I discovered the higher-end Sony TVs handle motion much better than any other LED I have seen. I also discovered via CNET that they have the lowest input lag for gamers. How come you have not reviewed the W802 or W900 LEDs, which more accurately compare to the Samsung 7000 and 8000 versus that real cheap R400?
Unfortunately, we had difficulty getting our hands on them, which is why we didn't test them.
What's the difference between Led Motion Mode and Sony Impulse Mode?
Functionally, it is the same. It is named differently because the Impulse mode is a sub setting of MotionFlow, something that isn't available in cheaper models.
I am interested in purchasing a 240 hz 4k LED TV. I am going back and forth on the Samsung 7100 or Samsung 8500. I usually watch Sports and Movies on the TV. Besides for the cost, are there any real differences between the two? Also, is there any brand TV I can look into. I am looking only to purchase a 48-50" size model.
The differences are mostly going to be noticeable for videophiles. The average person will be fine with the JU7100.
Note that no TVs this year are really 240 hz - the numbers listed with TVs are deliberately misleading, and most 4k TVs are really 120 hz.
Other brands to look into are Sony (priced similarly to Samsung) and Vizio (cheaper, but with good picture quality).
Regarding Samsung LCDs, can you explain how "Blur Reduction" "Judder Reduction" and "LED Clear Motion" settings affect the picture displayed and the differences between them? Also, when I turn LED clear motion ON, the other two settings are grayed out. Does the set apply blur reduction and/or judder reduction with LED clear motion ON, and to what degree?
'LED Clear Motion' is the equivalent of Sony's Impulse mode. It looks very similar. However, you can't turn that ON in game mode, so the input lag is high if you want to use it. It indeed disables both 'Blur Reduction' and 'Judder Reduction'. 'Blur Reduction' is the motion interpolation feature (the creation of new frames). 'Judder Reduction' is the TV trying to make uniform the display time of each frame.
Thank you for the detailed answer. Refresh rates and motion blur make a lot more sense to me now. So based on the reviews from the Vizio E Series, W800B, and Samsung H6350, it sounds like they all handle motion blur pretty well (with the edge going to Vizio and Sony for reduced input lag). I'm not necessarily interested in 3D or smart features. I play PS4 games, watch Netflix (from console) and ripped movies from my HTPC. But a balance of gameplay AND picture quality are desired. Also, my level of gameplay is "enthusiast," not hard core. It's the motion blur that bothers me. I don't notice the lag so much. That being said, would the W800B still be the better purchase, even though it's priced higher than the Vizio? or Would the Samsung be the better overall TV for good gaming experience while maintaining picture quality in movies? Thank you so much for your advice! Your site rocks.
Like you mentioned, all three of those TVs are great. The difference in terms of motion blur between them isn't big. Do you have a dark room? If so, you will probably like the W800B's Impulse mode, which reduces even further the perceived amount of blur (although it doesn't change the length of the motion blur trail). The Sony also has better screen uniformity than the Vizio, so it is worth the higher price if you really care about picture quality. The Samsung H6350 is great, but because you will be gaming most of the time, stick to the Sony.
Are you testing motion blur with the TVs smoothing effect turned off?
Yes. It doesn't make a difference for the pixel response time measurements (which is the basis for the score), but it does affect the clarity of the motion blur image we use in the review.
Since a lot of people prefer uninterpolated video, we display that image alongside the motion blur score, and present the interpolated image in the 'Judder' category instead.
I am looking to get a 55" or a 60" LED TV to go with my Xbox One. I am a huge Samsung fan, but I will get a Sony. I'm getting confused between the motion blur and the input lag. Which one do I need to consider more for gaming and movies? I currently have a Samsung plasma, but since they are not making plasmas anymore, I want to save it for when I get a house. I can just use it for gaming and not my main TV. So which LED can come close to that?
Input lag is a hit or miss thing; if you notice it you will hate your TV, and if you don't, a lag that is 10 ms better will look the same for you. Usually, the limit is 50 ms for most people. It doesn't matter at all for movies. Motion blur is something that can never be perfect. It doesn't really matter for movies either, because they are only 24 fps anyway, and most of the blur is from the actual footage for artistic reasons.
If you are picky, no LED TV will come close to the picture quality of a plasma. That said, they are good enough for almost everyone. The Samsung H6350 is the safest bet for an LED in the mid-tier.
I'm still really confused and on the hunt for a definitive answer to a very simple question. For mostly console/PS4 gaming, is native 120hz better for motion blur? I've heard yes, I've heard no, I've heard yes, but only if you enable "Gaming Mode". So lay it on me, real simple; is it worth paying the extra $$ for a 120Hz TV when the content is only 30fps anyway? And what is "gaming mode" doing to a 120hz signal? Is it "dumbing it down" to 60hz? I've been really satisfied with my 42" Samsung plasma for years, but it was only 720p. Just recently had the urge to step into full 1080p, mostly because of these high-detail PS4 games coming out. So I picked up a Samsung UN50EH5000FXZA (60Hz) on sale for $499. Took it home, calibrated it, and started playing Destiny. I IMMEDIATELY noticed the motion blur. It's horrible and almost non-enjoyable to play on. Now I have less than 30 days to take the TV back, but really need a solid idea what to go to market for.
No. The motion blur is not dependent on the TV's refresh rate, given the same frame rate as an input. The response time of the pixels (what creates most of the blur), is independent of the refresh rate. With that said, there is a correlation, but that's because manufacturers put better panels on their higher-end models, which also happen to be 120Hz TVs. So yes, it is worth spending more to get a 120Hz TV, but not because of the refresh rate.
Can you explain the judder ratings you perform? For example: 24p: Yes, 24p via 60p: No, 24p via 60i: No, Motion Interpolation (30 fps): Yes, Motion Interpolation (60 fps): Yes
Does 24p via 60i/p indicate whether a TV can identify 24p content in a 60p or 60i signal and properly reverse telecine it back to 24p and then display it? What do the motion interpolation ratings mean?
Yes, that's exactly it. 'Yes' indicated that a TV could play 24 fps content over that kind of signal, judder-free. The motion interpolation ratings mean that the TV can interpolate that kind of signal.
We've updated the section to make it a bit more clear what the judder ratings mean.
FYI, there is a problem on your test results/viewing angles page. Explorer keeps having to recover the page.
It's likely because of the number of YouTube videos on the page. Thanks for letting us know. We'll investigate further to try and find a solution.
I'm stuck between picking the Vizio M, Samsung JU7500, or JS9000. I am a gamer who loves movies, television shows, boxing, and football, so I need an all-around television. I recently purchased the Vizio, but the upscaling isn't as good as the others, according to your reviews and my observations. Which TV would be my best choice?
Overall, the JS9000 is the best TV we have seen this year, with great picture quality, some nice extra features (HDR, wider range of colors), and low input lag. That's the one we recommend.
Hi! I just purchased the vizio m50-c1 and immediately noticed the motion blur while gaming, my question is would the vizio 2015 e50 set be much of an improvement? I got great deal on the m50 and would only be saving $70 if "downgraded' to the e50 but the blur is a lil more than use to, my older vizio's seem to handle motion blur better than the m50. At this moment not too concerned bout 4k, I just want the best gaming experience I can get within my budget $500-$600. Thanks.
The Vizio E will have noticeably less motion blur. If 4k isn't something you are looking for, don't hesitate to get the Vizio E. Gaming will be better on it.
I just got the LG B6 last week. I've noticed very distracting stutter during panning scenes. I've tried disabling everything,and many other remedies, to no avail. The only thing that has seemed to help is adjusting the de-judder, but even slightly gives me the SOE, which I hate even more. Is this a bug in the software that would hopefully recieve an update, or maybe just certain frame rate content? I've seen alot of posts from people with the same issue. I love the quality otherwise, and really don't want to return it, especially since you've rated it the best in response time against all other TV's. I'd hate to go thru that trouble to get a different TV with the same, or even worse problem. Any ideas of a solution?
Stuttering in panning shots occurs because of the movie's framerate. This is a side effect of the TV's exceptional response time, as the frames do not blend together. You can solve this by setting the de-judder option to a low setting, 3 or 4 should suffice. This should only appear on low framerate content, and 30 or 60hz video should look very smooth. Unfortunately, even with this low of a setting, you will see some mild soap opera effect. If you're not a fan, it unfortunately isn't an ideal solution.
I've bought a LG LB6300 a month ago mainly for PS4 gaming. Lately, I've tried it on a very dark game, lights turned off and right at the first 30sec, I started to feel a headache as the TV seems to leaves trails of duplicated images (exactly like the duplicated RTINGS letters from your test). Even when turning slowly in game, in-game lights judder from left to right. I don't know if it's caused by the high contrast between the light source vs the dark corridors, but it's absolutely unplayable! It breaks my line of sight and turns my attention to the stuttering effect. I tried with the recommended game picture mode, and I've changed my icon to PC and changed HDMI2 name to PC. Now, I'm seriously planning to exchange it for a Sony W800B, but I'm also watching movies, sometimes from external drive, but you said it takes 15min to access the external device. Is it that bad, really? Also, I would like to know how your motion blur rating works? Because to me, the duplicated RTINGS letter from the LB6300 test seems much more annoying to my eyes than the blur trails from the motion blur test of the Sony W800B, but you still gave the LB6300 8.0/10 instead of the 7.5/10 on the W800B. Thank you for clarifying this for me. Your website and reviews are amazing!
I am assuming your PS4 game outputs at 30fps? This creates even more shuttering compared to a 60fps game. Subjectively, when you look at our motion blur pictures, most people would say that the duplicated logo has less blur because you can actually see the letters distinctly. Of course, this is a personal preference. We are considering changing our score to reflect the length of the trail instead. Concerning the W800B's slow USB drives, someone mentioned to us that there was a software update that fixed that issue if you list the files by folder. We couldn't confirm it though, because we don't have any Sony TVs with us anymore.
I have the UN55H7150. Is there a way to turn off the "soap opera" look?
Turn off 'Auto Motion Plus' under 'Picture Options'.
Do you have plans to measure color gamut of TV display panels outside of Rec 709? It would be interesting to see how 2015 flagship TVs actually handle P3 and Rec 2020 signals.
We are waiting to receive a new spectrophotometer before we begin testing the color gamut of our TVs on the Rec 2020 standard, but yes, that is in the works.
Hello. I'm a big movie lover and hate the "soap opera effect" on movies. Is there a TV you recommend that has "bad" or no motion control?
The soap opera effect is optional, and can be disabled in a TV's menu. If you love movies, just make sure you get something with judder-free 24 fps playback and you'll be all set.
Which 65" TV is better for watching movies and sports, the Vizio M-series or the E-series?
I don't want to buy Samsung. I had a bad experience.
The M-series is a bit better. The blacks are more uniform, and there are fewer darker patches on the screen. You also get the option to watch 4k.
If you don't plan on watching any 4k, though, get the E-series. The picture is nearly as good, and it's cheaper.
I'm sorry if this should be clear, but I just want to be clear. Were all of these tests done with the different motion blur correction modes turned off? So if I hate the soap opera effect and also want as little motion blur as possible, but done naturally, the first one listed (LG EG9100) would be my best bet?
And thanks for this great website! I've forwarded it to all of my buddies.
Yes, we do test the TVs' 'natural' abilities, without corrective modes enabled. And yes, the EG9100 is the best choice overall for motion blur, though the other OLED sets we've reviewed are about as good.
I was wondering when if ever HDTV's will come with native Refresh Rates over 120hz? This seems to be the highest "native" rate out now no matter what the cost or brand of the TV. Also, in all your testing has a native 60hz ever looked better than a native 120hz?
Some of the native 60Hz TVs do have very good motion handling, such as some of the Samsung IPS TVs (JU6400 and JS7000) or the 2016 Vizio D. A refresh rate over 120Hz may not be a priority unless it increases the motion handling significantly, which is unlikely.
Do you have any plans to test the Samsung UN55HU6840 or the 6950? These were on sale on Black Friday and there is some intense debate on the refresh rate of these TVs. Some say 60Hz, others say 120 Hz. Can you have 120 Hz at 1080p and 60 Hz at 4K? Trying the testufo site doesn't work on the TV's web browser, because it is a linux browser.
Unfortunately, no, we won't have time for them this year. You can verify the refresh rate yourself if you want. Look for the 'Auto Motion Plus' setting under 'Picture Options'. If it isn't there, or if it doesn't work, it is a 60Hz TV.
I'm in the market for a gaming TV that has motion interpolation aka (soap opera) that works with gaming (the Xbox One and PlayStation 4), something that works well and has average to low input lag So my question is, is there a TV that was built for gamers?
-Amazing picture
-Low input lag
-Motion Interpolation - Can be turned on for gaming
-Looking at about $1,000 to spend
-TV can be any size.
I love how the soap opera effect looks, and I'm really trying to find a TV that will let me use use that effect with gaming. Thank you so much.
There aren't any TVs that have low input lag while using their motion interpolation feature. We don't test for input lag while interpolation is running, so we can't make any recommendation for that kind of scenario.
The Sony KDL55W800B has great picture quality, low input lag, and also has motion interpolation for when you want to use it. Overall, it's the best fit for what you are looking for. You might also want to check out the Samsung UN55H6350, which costs about the same. It also has great picture quality and can do motion interpolation, but has higher input lag than the Sony.
How do you test for judder?
We use a special test pattern. It's a grid of 24 black squares that flash white, one by one, with all 24 flashing once each second. We then photograph the TV while it is displaying this pattern, using one second of exposure. If all of the squares are a uniform grayish color, then there is no judder.
If you would like to test a TV yourself, you can find the pattern here.
In terms of motion blur, since there is a new testing methodology being used for 2015 television sets, is it safe to compare motion blur ratings on a 2014 set to a 2015 set?
2014 was a subjective score, and 2015 is objective, so they're not properly comparable. Consider our 2014 scores for motion blur more like a general idea of what to expect.
My primary TV usage revolves around watching sports. Being used to a Samsung plasma for the last six years (it recently went bust), I am having a hard time finding something with good motion blur. Which one would you recommend given a budget of say under $1,500?
It depends on which size of TV you'd like to get. We list our favorite TVs for watching sports here, and several of them will fit the bill at different sizes. For example, you could get a 65" Samsung J6200 for about as much as it would cost to get a 50" Samsung JU7100.
Pick a size you would like (we suggest the largest size you can fit/afford), and then choose the best TV on that list that comes in at your target price.
I'm trying to decide between the JU7100 and JS8500 (65"), with primary uses being sports, cable TV, and video games. My main concern is motion blur. Coming from years of viewing a plasma and a CRT projection, I'm wondering if any LED TVs won't bug me, even good ones for motion blur, like these. Second, do both of these TVs have the same Auto Motion Plus settings for reducing blur without SOE? And lastly, do you think the better motion blur on the JS8500 is noticeably different to the naked eye? I'm not overly concerned with the contrast and black uniformity differences in these TVs as I'll be watching them in a relatively bright room, so trying to determine if the motion blur difference is worth the price? Thanks, this is an incredible site!
It all depends on how picky you are. Motion on any LED TVs will look different than on CRTs or plasma TVs (different, not necessarily better or worse, depending on your preference).
If you set 'Auto Motion Plus' to 'Custom', turn off both sliders and enable 'LED Motion Mode', it will reduce the apparent blur (via backlight strobing), but at the cost of a darker screen and flickering (also, it can't be used under the low input lag of game mode).
If you think you are really picky about motion blur, a Sony TV with 'Motionflow' set to 'Custom' and 'Clearness' of 5 will get you closer to a CRT/Plasma feeling (works the same way as Samsung's 'LED Motion Mode' described above, but can be used in game mode and is even more aggressive).
Most people won't notice the difference of motion blur between the JU7100 and the JS8500. It is there, but if you are not too picky you won't really see it.
We have a Sony 46w950a which is similar to a Sony w900a sold in US. Strangely i have noticed something very peculiar when watching football matches that the pitch on one half of the screen looks pale compared to the same pitch on the other half of the screen. Is this a lighting issue/screen uniformity issue or an issue in the source itself. This happens in all the football matches but when watching anything else (soaps or movies) its not noticeable or i cant find any un-uniformity in colors then. Your expert advice is urgently needed.
If the problem is always showing on the same side of the screen then it is probably a uniformity issue. To make sure, try to watch a different source on the TV showing the same kind of picture, like a computer with a football field filling the screen. If you can see the same problem then there is a uniformity issue with the TV. This kind of problem is really more noticeable in sports with playing fields of uniform colors. It is not uncommon but it shouldn't be real bad either. If you still have time to do so and you can't stand it, return the TV and get another one of the same model. Unfortunately, there is no guarantee that you will get better.
