The LG LN5400 LED TV has a good viewing angle and low input lag. However, its contrast is very low and it suffers from some noticeable motion blur. This TV is more suitable for a bright room due to its poor blacks.
Very good viewing angle. The colors stays true wherever you sit.
Low input lag. It is great for a gaming TV.
Average amount of motion blur.
Only 2 HDMI inputs.
Poor contrast ratio. The blacks will appear gray when you have the lights off. This isn't an issue in a bright room.
This is the LN5400 strongest point. The colors stays about the same at any angle. We measured a drop of half the contrast at 37°, which is really good for an LED. This makes the LN5400 a great choice for a living room with multiple seats.

Compare the LG LN5400 picture quality to other TVs
Should i go for the LG 47ln5400 or the Samsung 46f5000?
It depends what you prefer. If you want better blacks, go for the Samsung F5000. If you want a wider viewing angle, get the LN5400.

For the LN5400 can you recommend some calibration settings? I have looked on avs, not sure if its because this TV is new or unpopular.
Our calibration that we used:
All settings disabled
Picture mode: Expert 1
Color Temperature: Warm 2
Red offset: 0 Red gain: -4
Green offset: 0 Green gain: 0
Blue offset: 0 Blue gain: 18
Don't forget that the calibration depends on your room and actual panel, so you might need to tweak it.

Is it a real 120Hz refresh rate TV?
Yes, however it does not have motion interpolation. It does support true 24p playback though.

I just bought this model last night. The picture (both gaming on an xbox 360 and regular tv broadcast) seemed very dark. I could not figure out how to brighten even after trying multiple variations (gaming, cinema, etc.). Any advice?
The max calibrated luminance that we got was 212 cd/m2, which is definitely bright. First off, disable the Energy Saving option (ECO Mode). This features will change the brightness of the screen depending on the luminosity sensor. You will have full control after you disable that. Then, set the backlight setting to the max. Contrary to the brightness setting which affects the picture quality, the backlight setting only controls the luminosity of the light behind the LCD screen, which is what you want.

I just bought the 60LN5400 and I'm noticing input lag, even with game mode on. What size did you run the input lag test on? (would that make a difference?) I'm trying to fix this because I love the picture, just need lower input lag for FPS games.
42", but that shouldn't matter. Did you try disabling all options? You might also want to try using the other HMDI input (if I remember correctly, we used HDMI 1 on this model).
Jul 22 2013
How bad is the motion blur? I mainly plan on using this tv for gaming.
As shown in our video, it is average for an LED. However, because of its very low input lag, this makes a good gaming TV.
Sep 11 2013
Is it possible to update the 5400 since it does not have an internet connection? Can you upload the update to a usb?
No, the LN5400 cannot be updated, even by USB. Even if it was possible for this model, LG rarely puts out firmware updates for released TVs.
Aug 07 2013
Which one should i go for among LG LN5400 42 inch or Sony R450 40 inch?
If you are viewing it alone and directly in front, the R450 has a better picture quality. But as soon as you are watching it from an angle, the LN5400 wins.

I cannot locate anything in my 50LN5400 settings to control Trumotion on or off. The sales literature says it has the feature but I can't find it.
That's because it doesn't have it. There is no Motion Interpolation (aka Soap Opera Effect) feature on the LN5400.
Nov 10 2013
I saw a 32LA6200 on display at a local shop, picture seemed 'live' and a far cry from a 32la613B right beside it, I assume this is the soap opera effect and I loved it! Now my question is, I currently don't need smart or 3D yet so I am willing to trade them off for a bigger sized TV, will the 42LN5400 have the same soap opera effect as the LA6200? If not, what are my other options?
Why does it say 1080i 60hz everytime I push the info button? It's on a 42ln5400 LG. It has 1080p 120hz.
This is normal. The info button displays the input signal resolution and frame rate, not the one of TV native panel. This means you are using a 1080i source.
Jul 21 2013
Is the panel and true motion equivalent to 47LN5700? I am not interested in the "smart" features of the 5700 but if the image/motion control was better I would probably justify the price difference.
Yes they are the same except for the smart TV interface.
Jul 24 2013
Kinda of a dumb question but do you guys know which tv has the best blacks the M2350D or the LN5400?
We did not test the LG M2350D monitor, so cannot say. I would guess in the same ballpark though.
Sep 01 2013
Does the graphics of video games may suffer because of its low contrast? Or it doesn't really matter when it comes to gaming?
Compared to movies, most video games are fairly bright. They usually do not have a lot of dark scenes. Therefore, the contrast is not the primary factor when choosing a gaming TV.
Oct 21 2013
So for Xbox 360 and occasional movies and tv shows from hdd, would you recommend this 42LN5400 over the Samsung 42F5000?
It depends on your room. If you need a wide viewing angle, get the LN5400. Otherwise, get the F5000, which has better contrast and less reflections.
Oct 24 2013
Can you turn off true motion in this model?
It doesn't have the motion interpolation setting, so it is always off.
Nov 19 2013
I am curious, you answered a person telling them to try HDMI 1 for gaming - I plan on getting Xbox one and PS4. If I have them both plug in will one suffer from input lag because it's in HDMI 2?
No, you shouldn't have problem with this. We just mentioned it to make sure he had the exact same setup as us. We actually followed up in email and he said disabling all settings fixed his issue.
Nov 24 2013
Does the LG 55LN5400 actually have a headphone jack?
No it doesn't.
Dec 26 2013
How do I disable all settings on an ln5400 to get the best input lag time?
You need to go through all the picture settings in the menus and disable them one by one.
Dec 31 2013
When plugging in a USB flash drive I only see options for Pictures and Music, but not Video playback. Is this normal? I can't seem to get it play any video files at all of numerous different formats
Yes it is normal, this TV doesn't support video playback via USB.

I live in the country and currently have an aerial antenna. I am looking at the 55ln5400 or 60ln5400. Will this tv work well with this setup?
Yes, it does have an antenna input.

I have recently purchased an Xbox One and have the LG LN5400. I'm struggling to find the optimum picture settings for my gaming. What settings do you guys recommend for this purpose?
The settings that we used (as described in another answer) are great for gaming because all options are disabled so it has minimum input lag. The picture quality will also closely match the monitors of the game developers (they also get calibrated to the same color temperature as us).
Nov 07 2013
What do you think is a better TV for gaming? The LG 42LN5400 or the Sony KDL-40R450A? I ask this because I have the 42LN5400 and when I play a fast game like NHL, I notice motion blur, is it better on the Sony or about the same?
The KDL-40R450A has slightly less blur but the difference isn't big. Check out both our videos of motion blur. Note that due to the low frame rate of the current generation of console (30 fps), there will always be perceptible blur on all TVs.
Yes, it is equivalent, but for a different country.
Dec 19 2013
Is the 60ln5400 worth the price difference against the e601i?
We haven't test the Vizio E601i, but they probably have the same panel inside so a very similar picture quality.
Dec 19 2013
What is the difference between the ln5400 and ln5420?
The LN5420 is an international variant of the US model LN5400. Besides adhering to different country specific regulations, it also features a built-in DVR feature.
Dec 31 2013
After some time of being on, the screen goes gray and has lines through it. I have to shut it off for like a half hour before it goes back normal. Common issue? Easy fix?
This is not normal. Return it or call LG to get it repaired/replaced.
Dec 31 2013
How do I get movies to play from my memory stick? I load it but there is no video option, just picture and music?
You can't play video files with this TV.
Dec 31 2013
I have a 55LN5400 and there is no mention of TruMotion in any of the TV's settings. Is it enabled by the input source? Unfortunately I only have a cable box outputting at 1080i and 60hz, so I don't have a higher quality source to test against.
Ours also didn't have that setting, although we didn't tried a wide range of input sources.

I just brought 47LN5400 model yesterday. I was bit disappointed about the USB feature, as it does not play any movies/videos. So, could you please suggest me the best option to play movies by using USB on this model. And also what would be the best option to convert my LN5400 to a smart TV?
Roku is probably your best bet to convert your TV to a smart TV which also supports USB playback of video files, assuming you don't already have a device that does this (like the PS3).
There are reports that even disabling TruMotion that this doesn't eliminate the "soap opera effect" from the LN5400. Was that true in your testing?
No it wasn't the case in our testing. As you can see in our motion video, there is absolutely no soap opera effect created and we couldn't turned it on. May be the soap opera effect is present in other picture modes, but it wasn't present in the 'Expert 1' mode that we used for testing.
Jan 10 2014
About motion blur, which TV is better and how much is the difference (LN5400 vs Samsung F5000)?
We haven't tested the F5000, but we expect it to have slightly less blur than the LN5400 due to the panel technology (IPS panels usually have slightly more blur than their counterparts). The difference can't be seen on TV shows and movies though, its mostly on video games.
Jan 25 2014
About your claim that the TV doesn't support video playback via USB, I have a 32LN5400 and it play well all sort of movies.
About everything else in your review, I'm impressed, very good and accurate review.
Picture of pixels is a great idea. When I was buying tv set I didn't know about your site, so I was taking magnifier 15x to store with me to figure out what tv have what panel.
Also, about sound, it's on low end.
Thanks for the feedback. Which country is your 32LN5400 from? Sometimes these features are country specific.
Update: We followed up on email and it was the Central European version. Another person also mentioned the Philippines version does play movie files. So it does appear to be a country specific feature.

I have an LN5400 and when I change HDMI 1 to HDMi 2, I see in information over the screen: "16:9 1080p 60hz". Shouldn't it be 1980 and 100Hz?
No, 1080p 60Hz is correct. It displays the input signal, not the refresh rate of the screen. This is normal.
Feb 21 2014
I just purchased a LN5400 and I'll be receiving it in a few days. I enjoyed reading your assessment of this model; also, the calibration settings you used in your testing of it. My question is about powering up the TV. I have a power strip surge suppressor I had planned to use, but I noticed on the max load rating that it is only 60 HZ. Does this mean I can't or should not use this power strip for the LN5400? In general, I don't know that much about electricity and even less about the internal workings of a TV. If I can't use my present power strip, could you recommend one that I should use?
Do not worry about this, you can use your power strip with your TV without problem. The 60Hz written on it refer to the frequency of the alternating current as an input (what runs in your house), not the refresh rate of the TV.

Is one of the HDMI an HDMI ARC (audio return channel) as I would like to be able to transfer audio from the TV back to a home theater receiver to listen to the TV's audio through it.
Unfortunately, no. But the LN5700 does have HDMI ARC.

If you were to pick a tv for gaming on an Xbox, would you go with the LN5400 or LN5700? Would an input lag under 75ms be noticeable? Also, besides the smart interface, does the LN5700 offer anything that would make it a better buy over the LN5700 (in terms of gaming and occasional movies)?
I would go for the LN5400. The smart TV features on the LN5700 are mostly redundant if you have a console, because a lot of them can be also found on a console (like netflix). An input lag under 50 ms is not noticeable for the majority of people, but hardcore gamers will appreciate the lower input lag on the LN5400. Save your money and go for the LN5400.
My house is an open floor plan design with the TV in the center. The sun rise on the back side which I has several average size windows and the sun sets on the front, which has tall long windows that beams sunlight. What TV is the best for this room situation?
You probably need a TV with a wide viewing angle and low reflections. Check out the LG LN5400.
LG 47LN5400 shows "TruMotion 120Hz" on LG website, no reference to actual refresh rate, and no reference at all to this feature in the box or manual. In the stores (Bestbuy, Futureshop, Costco, etc.) they are advertising as native 120 Hz and TruMotion 120 Hz. From your table, it looks like trumotion 120 hz is actually 120 hz but reading over your article it seems like it could be 60 hz or 120 hz and remains a hidden fact.
The LN5400 does not have motion interpolation, but it does have 24p playback. The actual refresh rate number does not matter. The motion blur is the same as the LA5700 or the LA6200 (check out our slow motion videos).
I would like to get this over the LN5400. Does interpolation make a difference in video games? Also, is there a way to reduce the input lag to make it comparable to the LN5400?
Interpolation need to be turned off when gaming because it increase the input lag too much. In our tests, the lowest input lag that we got for the LN5700 was 67ms. We only spend around 5-10 min reducing it though, so it is possible (but not very likely) that you get a lower one if you try harder than us.
Which model would be better for watching sports (NHL hockey) or playing games, the LN5400 or LN5700? I really like the low input lag of the LN5400, but I am curious how a model with the same panel and a better dual core processor can not at least match the same low input lag?
If you do not want Smart TV features, just get the LN5400. The problem for the input lag is most likely the Smart TV features. While the processor is faster, it has a whole lot more of stuff to do.
What is the best TV to buy for an entertainment joint ie a club? 40" plasma or LED and from what company, LG, Sony or Samsung?
Go for an entry level LG LED TV. Plasmas are more prone to image retention, which could be a problem for a business that display static images like ads. Also, there are very few plasmas of this size, and most of them are 720p only. An important constraint for a business is the viewing angle. LG TVs have a considerably larger viewing angle than Sony or Samsung TVs. The downside is a lower contrast ratio, but it is less important than viewing angle for a club. Check out the LG 42LN5400. It is a basic TV with no superfluous features and a great viewing angle.
I'm pondering over two different LED TV's the Samsung UN46F6300 and the LG 47LN5700 both are smart TV's and slightly different cost. Which is better?
It depends what you prefer. The UN46F6300 has an overall better picture quality, especially the contrast. However, the viewing angle is less than the 47LN5400. If you don't care about the viewing angle, go for the Samsung.
Looking for a TV for our living room. It has four windows (two have blinds, the other two are 10-15 feet high without blinds) which makes me think a LED would be best. However, given that the room is awkwardly configured, i'm worried about the viewing angles of an LED. Will mostly be watching TV, sports, and the odd movie. Looking to spend around $500-700 Any advice?
If you need a wide viewing angle and have a bright room, check out the LN5400.
If I am primarily watching sports, would there be much difference between the LN5400 and the R450? Also, if I were with a group of people, which would be the better TV?
There is less motion blur on the R450, making it better for sports. However, the viewing angle is a lot better on the LN5400, which is useful with a group of people watching. Therefore, it is a trade off and it depends on which factor you value more.
I heard highly conflicting reviews about this tv. One saying the picture quality is the worse there is and the other review says the quality is quite good. I don't need wide angle, I need good picture quality, good colors, contrast and lower motion blur. So which tv is best? F5000 or ln5400? I am confused because they say that the f5000 is like a lottery, you may get the s-pva panel or a horrid panel.
All models, especially the lower end ones, are a lottery of panels. Samsung is worse than LG for this variance. You will be better of with the F5000 than the LN5400 if you do not need a wide viewing angle, so hope that you don't get a bad one or return it if you do.
I'm getting ready to buy my first flat screen TV but I'm pretty limited on space as my house is pretty small. I figure the ideal size would be 35"-40" for the space I have because there's no way I could fit anything larger. I definitely want a TV that has a great picture, but it needs a great price to go along with it.
There is no plasma of that size so it simplifies the problem for you. Do you sit directly in front of it or at an angle? If you sit in front, go for an LED like the UN40FH6030. Otherwise, go for the 42LN5400 because it has a wider viewing angle (at the cost of a lower contrast though).
I want to buy a TV to my parents house! About 50" or 55". They are old and can't see very well, also, they like to watch TV on Sundays mornings, and every night with the lights on. A LED tv is a better option right? Which led has a good wide angle to watch as well?
Yes, go for an LED. If you want a wide viewing angle, go for an LG TV, like the LN5400. It has a considerably wider viewing angle than average and its main downside, the poor contrast, won't be an issue if they watch it in a bright room.
