The JU6400 is a mixed bag. It is an excellent option for gaming, great for sports and well-suited for a well-lit family room. Unfortunately, it won't be as good for movie lovers who like to watch TV in a dim room, as the TV has poor blacks and suffers from judder. Depending on your viewing habits it can be great, or bad.

Additional Review Notes

Differences between sizes

The 55" Samsung UN55JU6400 that we reviewed has a PLS panel (version FD05), which is a sub-category of the IPS family, and which produces grayish blacks, and has a wide viewing angle. If someone comes across a different type of panel used, let us know and we will update our review. Thank you in advance.

Some of our visitors reported that the 40", 43" and 48" version of the JU6400 has VA panels with better contrast ratios and worse viewing angles.

38
What's the difference between ju6400 and ju6500?
The JU6400 doesn't support 4k @ 60hz @ 4:4:4 and has 1 less HDMI input. Also, some JU6400 have worse blacks/better viewing angle than the same size in JU6500 (the 55" for example).

I was just about to buy this TV today! Thanks for saving me a huge headache of returning it. Going with the XBR55X810C instead.
We are happy to help. Enjoy your new TV!

Trying to hook up a Samsung Bluetooth soundbar to this TV but cannot figure out how to get to the Soundshare feature. Any help?

The JU6400 doesn't have Bluetooth, so you'll need to connect the soundbar via HDMI ARC or digital audio (optical).

Update 2017/02/10: To the best of our knowledge none of the US models have bluetooth but some models in other countries do, such as the UA55JU6400K.

I am debating between the J6300 and JU6400. Cost is not a concern, and 4K is not a deal breaker. I just want the best TV for broadcast sports and video gaming. Any suggestions?
The JU6400 has less blur and lower input lag, so it's better for gaming and for sports, but the blacks are much worse. If you want good contrast and black uniformity, get the J6300. Its picture and gaming performance are both still very good, and it's more well-rounded.
10
Is this the same as the UN48JU640DFXZA, which Costco is offering at $270 off with its Black Friday sale?
Yes, although we haven't yet confirm if the 48" size also has the same type of panel as the 55" we reviewed (IPS), so it is possible that the viewing angle and the contrast ratio could be different.

The JU6400 rates higher than the J6300 series (7.7 vs 7.5), yet you have noted as not having good PQ. Is that in relation to other UHD TV's? My living room is very bright, so this looks like a good match from that standpoint. Given equal sizes, is it better to stick with the J6300 or pay only a little more to get into 4k land? We never watch Blu Rays or DVD's. We generally watch TV, but will watch the occasional streaming movie. TIA.
You make a good point. We made some adjustments in the review to put more emphasis on the fact that this TV is great in a well lit environment (it's poor blacks and contrast won't be as apparent). Since you have a bright room, the JU6400 will serve you better than the J6300.

I have the UK version of this 55" tv and it does full chroma 4:4:4 at 4k@60hz but only in hdmi port 1. Needs to turn on uhd color then set the hdmi port function to pc and full 4:4:4 chroma is achieved. Beware of the quality of the cable though, i had a high quality cable but it was a little short for my pc so i bought a 1m extension, thought that was high quality as well but it wasn't. Had to move my pc case closer to my tv so the high quality cable alone was connected and voila, full chroma, 4k@60hz. Couldn't tell you how relieved i was, i read your review about the tv, was put off, did a bit more research and found the work around. Hope this helps, thanks.
Unfortunately, it doesn't work on the U.S. model. We just updated the firmware to 1440 and the 'UHD Color' option is still nowhere to be found in the TV menu. Thank you for the information though, it could surely help others in the U.K.

Mine doesn't have an IPS panel since the blacks are black and the viewing angle is narrow. I just got the 43" JU640D, which is the equivalent of the JU6400, from CostCo. Hope this helps. I guess I can't use your picture settings, since they are different panels.
Very helpful. Thanks! If you would be willing to take and email us a closeup photo of the pixels, that would be really great.
Use our settings for the Samsung JU6500. They should work well.

What is the difference between the JU6400 and the JU640D? I've seen the JU640D in Black Friday ads. Is it a cheaper derivative?
They're the same, just numbered differently to make them more difficult to price match.

Hello, would you recommend the JU6400 vs. the J6200? Costco has them for about the same price ($429 vs. $499) The JU6400 is a 40" and the J6200 a 55", but I honestly don't care about size, because we have a small living room. Also, the living room is not very bright. Thanks!
Get the J6200. It has better overall picture quality (particularly for contrast), and the larger size really will make a pretty big difference, too.

I was wondering if you have reviewed the Samsung un43ju640D? I'm looking for a 40"-43" tv with a good picture, don't really need 3D and all the apps. I saw that u reviewed the ju6400. I wasn't sure if it was the same tv. I noticed the un43ju640d is 120hz and the ju6400 is 60hz. Thanks.
The un43ju640d is 'Motion Rate 120' but has a real refresh rate of 60Hz, not 120Hz. It is the same TV as the JU6400 that we reviewed but it might have a different panel (VA) with better blacks and contrast.

I recently purchased this TV due to the significant price reduction of the 40" over black Friday and the generally positive reviews. The TV looks nice, and I'm happy, but I'm having problems with the smart apps. Can you tell me which version of the apps you are using? Mine says 1.0 (and firmware is 1431 I believe).
I cannot access the UHD content of Amazon, though I do have a prime account I am logged into. Neither Amazon nor Samsung is able to figure out why. It would be great if you could post pictures of what your interface looks like so we can see if ours match (in case there are different firmwares floating around).
Samsung confirmed for me that the TV's will sometimes fail to see new software and not update automatically (you have to update it manually via USB in this case). Amazon also told me they have heard of other cases of users of Samsung TVs having different apps available on the identical 2015 TV, and are unsure of why. I believe my TV has an old Amazon app that is not UHD compatible, but I don't know how that could be and I don't know how to confirm this or update it.
Our Amazon app is v. 4.40003, which is the latest version (IMG). Our firmware is v. 1422, which is also the latest available for the 55" JU6400 (IMG).
We haven't had this problem with any of our TVs, so our only recommendation for now is to try resetting the Smart Hub, and then to perform a factory reset on the TV. If that doesn't fix the problem, you should contact Samsung for assistance in updating the TV via USB.

My TV has a UD03 panel. Is the FD05 better, or should I keep my current panel?
The UD-03 is from Samsung, and Samsung panels are generally considered to be slightly better than those from other brands. Keep your current panel.

I was looking at buying the UN40JU640D at Costco. Do either of these models have the RVU technology that DirecTV uses to wirelessly connect to a Genie DVR receiver?
I'm been reading conflicting information where someone mentioned this could only be used via Ethernet and not transmitted wirelessly. This makes a difference, as I wanted to use this as a "roaming" TV that I could use out on my deck outside, and so I'd rather not connect via Ethernet.
Both models should work wirelessly with your DirecTV setup, but since this is not something we test and there is conflicting information out there (much of it appearing to be outdated), you should contact DirecTV to see if they can confirm for you.

After purchasing the 640D 48" and comparing in my own living room with the 6400 40", Samsung finally cleared up the difference. "Visitor: Could you tell me what type of panel is in the UN48JU640DFXZA. I know that it is led, but is it a TN? Kate: The "panel variance" that you may have been reading about refers to the type of panel that is installed in our Samsung TVs. All panels, regardless of the code, have been verified and meet the manufacturing requirements that have been set forth by Samsung. The code only signifies which factory the panel was manufactured at. All Samsung TVs for US distribution are assembled and tested in the United States with our stringent Samsung quality standards before being released for purchase. Visitor: is it a TN or an IPS? Kate: It is a TN." This was our conversation. The proof was in the comparison of the two right in front of me. I returned the 640D. I do NOT recommend that tv.
Thank you for the clarification. We added the information in the Q&A.

How does this have a 9.5 on games? It has a 26.4 input lag and you gave it a 6.0 as a monitor? The JU6500 was only an 8.4 for games but it has 26.5 input lag (same) and 8.0 as a monitor. The JS7000 was a 9.3 for games with a 27.4 input lag (highest) and a 8.0 as a monitor. You would think the JU6500 is the best. Please help me understand this. Thanks, Roby
Our scoring system is explained here. PC Monitor only weight for 6% of the overall 'Video Games' score while 'Motion Blur' also weight in for 63%. The TVs mentioned here have about the same input lag but the JU6400 have near perfect motion blur/fastest pixel response time (score 9.9 for Motion Blur). This result in a clearer picture in about all games. This explains why it managed to score higher in the 'Video Games' category.

On the Samsung website, it doesn't list this TV series as having an IPS panel. Are you sure the JU6400 series uses an IPS panel? Can you direct me to where this can be confirmed? I'm looking for an IPS panel with great viewing angles and that will still have great color from straight on.
You almost never see the panel type listed. The unit we reviewed is definitely IPS. You can see the order of the colored sub-pixels is different than VA TVs (compare the JU6400 to the JU6500), and you can also see in this video that the panel retains its quality up to a wider angle (compare to the JU6500).

Looking for a tv between 40-49 inches that has the best soap opera effect. Price is not an issue. I love the soap opera effect and just want the best, which tv do you guys recommend?
As a rule of thumb, for the soap opera effect, Sony > Samsung > LG. In that size range though, you don't have a lot of choices. The Sony 49" X830C would be good. Set 'MotionFlow' to 'Smooth', and 'CineMotion' to 'High' and you will get a strong soap opera effect on it. Keep in mind that this TV has worse blacks, but better color accuracy at an angle than average.

When you guys measure the ju6400 on motion is that with the auto motion or soap opera effect turned on or off? Also how come the all black screen above that shows the clouding and flashlighting looks so bad but cant be seen on the other pictures with black on the tops and bottoms of the movie playing? It looks so bad. I've seen Walmart LG and Vizio that were a quarter of the price that seemed to look better on all black screen from what i remember? Love the site. Thanks
We do both for motion blur. The picture under the 'Motion Blur' box is without interpolation (Auto Motion Plus). You can find a picture with motion interpolation under the 'Judder' section just beside 'Motion Interpolation (30 fps)'. If the TV is able to interpolate a 60 fps signal, then the picture would be posted in that same section too. For the black uniformity picture, we set the camera with a longer exposure so issues can be seen. The picture from the James Bond movie has a shorter exposure so issues aren't that much apparent. On a pitch dark room with an all black screen, you would still see the problems. In store, for the same reasons (too much lights), you don't really see screen uniformity problems.

I have the ju6400 and is it possible to connect a pc and use this as a second monitor? I have a DVI to HDMI cable that I have used on HDTVs in the past but when connecting to this one I get "unsuported" error message. I tried using the Samsung software but that was a waste of time. Thanks.
Yes it is possible, but it depends on your graphic cards. DVI to HDMI cable won't work at 4k, so select 1080p instead and that should fix your issue. Also, change the type of the input to 'PC'. If you want 4k, especially at 60hz and 4:4:4, you will need a graphic card that supports HDMI 2.0 (a DisplayPort converter won't work).

I guess my question isn't really a question, but more of a comment.
I own the Costco version of this television. UN65JU639D. Granted I will agree that this TV has contrast, black level and color problems, there are several things that you can do to minimize these issues that aren't mentioned here.
First there is a setting on this TV labeled black level, with 3 options: dark, darker and darkest, I have found if you set this to darker it takes care of a lot of the black level problems.
Secondly, to take care of the color problems there is a setting under white balance, color space, with 3 options: auto, native and custom. If you set this to native, I have found that you're probably not going to get the color much closer. Hope someone will find this useful.
Thanks for writing in with your suggestions. We find enabling the 'Black tone' setting removes some of the detail from darker portions of an image, and using the 'Native' color space doesn't really help make the color more accurate, but rather oversaturates them, making them 'pop.' Still, both could be worth trying if people want a vivid look with darker blacks, and don't mind the downsides.

I bought this model for the home and did not see any way to skip past internet connection in the setup. Not a problem for the home, but if I were to buy this model or any smart TV model for a summer cottage for broadcast viewing where there is zero internet access, can one skip smart TV setup and use it as a standard TV? Is internet access required to go through the first-time setup?
When you reach that part of the setup, press the right arrow button on the remote, and you'll be prompted to skip connecting to a network.

Do you know what the major difference is between the JU6400 series and the JU6401 series?
This is the same series. Slight variation in model numbers usually mean a change in design or a store exclusivity (so it cannot be price matched). In this case, from the specs, the JU6401 has one more HDMI port. Expect them to be pretty much the same.

I'm looking to buy a new TV that will become my office/man cave display. This TV will be used for gaming, sports, and possibly as an external monitor. Factoring in the quality and the prices of the following options, which do you suggest I should go with? Samsung UN60JU6400 ($249), UN55JU6700 ($449), UN50JU6500 ($399), or the Vizio D50u-D1 ($154). Is there a clear winner in this group based on my usage and price? How about a clear winner out of this group based on price and general TV usage (gaming, streaming, TV & movies)?
Go with the Samsung UN60JU6400. It is one of the TV tested that had the least motion blur and the input lag is also very good, so for sport and video game it will perform really well. For the price that you can have the UN60JU6400, it is very hard to beat and you will have a bigger TV.

Note that in our reviews, we tested the 55" version that have an IPS panel, all the other size use a VA panel who has better black and better contrast ratio. So the UN60JU6400 would have had a better score in the Movie usage rating.

Which input is the HDCP 2.2 compliant? I'm trying to hook up a 4k player, but I need the 2.2 correct?
Yes, to watch the latest UHD Blu-ray movies, you will need an HDCP compliant HDMI port and all 3 ports should be HDCP 2.2 compliant.

Dell offers a great deal for Balck Friday, UN65JU6400FXZA. On their page it says the TV has a 120 hz Motion Refresh Rate. Your review shows 60 Hz. Am I wrong, or are these TVs different? If it's 120 judder problem would be solved right?
They're the same. Dell is listing the 'Motion Rate,' which in this case is equal to twice the real refresh rate of 60 hz. The judder problem will still be there.

I was just googling for settings and just realized I bought this TV. I got the JU640D. I wish I had known because I'm using this TV for dark room movie viewing. Awesome. I'm too lazy to return I think. At least for now. But maybe update this review to include the SAM's model.
That's a good suggestion. We'll look into making that more clear in the future.

How can we confirm if the panel is ips or va. Mine is (ua55ju6400k). Also does the panel you tested has light bleed problem from the bottom right corner. My tv also comes with Bluetooth which i have confirmed by searching on my mobile Bluetooth. My tv has a yellowish tint on the picture is there any way to correct it?
The JU6400 we reviewed has an IPS panel but it could be different for you since your TV isn't from the U.S.. It is easier to tell on LG TVs from a close up picture of the pixels but for Samsung TVs the IPS pixels look very similar to their VA counterpart. The general rule is that IPS TV have good viewing angle and grayish blacks in the dark. Also, if you watch the TV up-close and move your head around, the blacks 'move' on the screen. On our JU6400, we have light bleed at about 3/4 of the top right edge (see it here). It is possible that your TV has bluetooth and not ours since they come from different countries. Is the yellow tint from our settings? This come from the warm settings we use. You can try to change the 'Color Tone' to something cooler.

Surprised to see 6400 better than 6500 in almost all the segments except for 6400 low light movie watching. But, on paper, 6500 looks strong. Can someone tell me if you have tried the 6400?
This come from our measurements and hours of testing on both TVs. The overall score of the JU6400 is higher because it scored better in more categories but if we just talk about picture quality, the JU6500 has better blacks and contrast that makes it's picture look more vibrant. Also, those two TVs use different kind of panels inside. The JU6400 55" that we reviewed has an IPS panel and the 55" JU6500 a VA panel. It would be interesting to see how a JU6400 with a VA panel measure up to the JU6500. Unfortunately for now, we only review one size of each TV models.

First time for a large flat screen to be used in my living room. I don't care about sports or video games but do care about living room and sound. Which would you recommend: Samsung 60 JU6400 OR Samsung 60JU7100? Thanks for this great site. It is so informative.
We are not sure yet if the 60" JU6400 use an IPS panel like the 55" we reviewed but if it does, it won't have great blacks and contrast but a wide viewing angle that might be good for wide living room with seating on the side of the TV. The JU6400 is also good to fight reflections but the JU7100 is even better. Any viewing on the side of the JU7100 won't be great though but the picture will be better than the JU6400 if you watch TV from front or in a dark room. The final choice depend on your room setup and viewing habits but the JU7100 is generally considered to offer a better picture in most situations.

Where can one find out what WIFI speed is in a TV? Have a Samsung that is great on WIFI. Returned a 49" that could not get above 10MBs when internet WIFI is at 64MBS. I'm hopping that the JU6400FXZA will work.
It is hard to tell. The TV speed rating shouldn't be a problem but it is directly dependent on your home setup. A TV wireless adapter could perform better than another and unfortunately, there is not much clue to get before trying it out. Assuming there is not much interference or walls between the router and TV (and from a technical standpoint), this TV shouldn't have problem streaming ultra HD contents from services like Netflix on most 802.11n networks.

Should I go for the Vizio 55" E series Tv 1080p or a 48" 4k ultra hd samsung. Both will be around the same price. Want to be able to play video games, watch sports and movies at night. Thanks.
Unless you plan on watching 4k contents in the future and that you don't sit any farther than 8' from the TV, the bigger size of the Vizio 55" is more worth it. It will be good for your usage.

If the price for the JU6400 and J6300 were the same for 65", which TV would be best? This would be in an average lit setting and 11 feet away from the couch. The TV would be used for TV shows on HD channels, Netflix, Hulu, and sports.
At that distance, the JU6400 wouldn't have the advantage even if 4k. Because the J6300 doesn't have judder in 24p movies and that it has better motion interpolation, this would be the better choice.

Awesome site! Very useful information. My family just ordered a UN65JU6400. I'm a little concerned because you are rating it has a bad TV for movie watching. Is it bad for reality TV shows as well? We have a sectional sofa so people will be sitting perpendicular to each other. So some people will be watching the TV at a wider angle, which you say this TV is good for. But we do like to have family movie nights where we won't necessary dim out the lights but lower the brightness just a tad. Do you think we should cancel our order on this TV? And if so, what other TV would suit us better? Thanks in advance.
We expect the 65" JU6400 to have a different panel (VA) than the 55" we reviewed (IPS) so expect better blacks and contrast. The picture quality stays the same for all contents you watch on the TV. Unfortunately, the 65" won't have as wide viewing angle but you can't have that and the best picture quality at the same time. Try the TV in your room first and decide afterward if a wider viewing angle would be more suitable. The 65" Sony x810c would be a good option for a wider viewing angle.

With the Samsung JU6400 the picture mode "MOVIE" did not seem to look good in a bright room. Do you suggest staying with MOVIE mode and then make very large adjustments, or using STANDARD mode and doing small adjustments? With audio, in any sound mode selected, a spoken "S" sound often sizzles. I cannot find a simple Treble +/- or Base +/- audio adjustment in the menus. Does it exist?
Try movie mode, but increase 'Backlight' to the max. If you still doesn't like it, try changing 'Color Tone' to something colder. If you are still not happy, then use Standard mode.
As for the sound, you can play with the bass via the equalizer. There is no treble option though.

How are you guys? Thanks for all the info. Well, my question is, I bought the 55JU6400 and when I turn it off it makes a crackling sound for about 10 seconds, then goes to a low buzzing sound that you can only hear if you go behind the TV. The sound goes away if I unplug it. Should I be concerned? I have until November 15th to take it back. What should I do guys? Thanks, and have a great day.
The same thing happens with all Samsung TVs, so it's nothing to worry about. It's just a component that is powering down.

Awesome site, great information, keep it up you're helping so many people. My question(s) is are your best settings listed the same for all sizes in the 6400 series and for game mode do you use those same settings as well (aside from movie mode) I have a 48 inch 6400 in game mode and can't change all the settings you have here, I seem to be unable to change the 10 point settings which is grayed out. How big of an impact does this have on overall picture quality? Any other input on optimal picture quality in game mode is appreciated. Thanks.
That's correct, the settings have to be changed with game mode disabled. The 10 point settings are more fine calibration, however this will differ depending on manufacturing differences with each TV. As such, we do not recommend you copy our calibration settings, however you can try the 2 point settings to see if you prefer the picture and otherwise you can revert to default. For gaming ensure 'Game mode' is enabled for lowest input lag, and disable all other settings (Dynamic contrast, Digital clean view, MPEG noise filter, etc.) Adjust the color temperature and backlight to your preference.

I wanted to verify is the above review is on UN55JU6400 and not the UN55JU6400FXZA ? If so, is the UN55JU6400FXZA a better contender from the UN55JU6400 ?
The unit reviewed is the UN55JU6400FXZA, with version number FD05. This refers to the same TV, including the FXZA is just the full model number and indicates it is for the US market. Other sizes of the JU6400 have a different type of panel (VA) which may result in better picture quality but a more narrow viewing angle.

Given that you say the UN60JU6400 has a better panel and picture than the UN55JU6400 that was originally tested, why haven't y'all done an updated review? I'd be interested to know what the ratings are for the 60" version as opposed to the 55".
We don't have enough resources to buy multiple sizes per TV models, so we buy the most popular size, in that case the 55 inch. So we did not have this specific model in our lab to do more testing unfortunately. But we know for a fact that VA panel have better contrast ratio resulting in deeper black. In that case, it would certainly score better than 5.4 in contrast. You can see here to understand the picture quality rating system.
We are not taking any more questions for this product because we no longer have it in our lab.
