LG LN5400 LED TV Review

Reviewed Jul 10, 2013 By Cedric Demers
This television has been discontinued.
It was replaced by the LG LB5800

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 stay 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.

Black: 0.132 cd/m2
White: 102 cd/m2
Contrast: 773 : 1

The LN5400 does not perform well in a dark room. The blacks are gray due to the poor contrast. If you want an LED TV for a dark room, you will be better served by a Samsung like the F5500.

Viewing angle: 37 °

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.

LG LN5400 Uniformity

The backlight uniformity is average for an LED.

Bright Room

Reflection: 3.4 %

It performs a lot better in a bright room where you can't notice its poor blacks. The reflection is slightly more than average for an LED.

Max white: 212 cd/m2

The brighter the scene, the better it performs.

Like most LG TVs, there is slightly more blur than average. Most people won't notice it though.
It supports 24p playback for movies. It doesn't have motion interpolation (the soap opera effect).

LG LN5400 Input lag
Input lag: 33.3 ms

The input lag is very low on this TV.

If you don't have a dark room, buy this TV. Its only major downside is its poor blacks when you have the lights closed. With the lights on, it is a solid TV with an impressive viewing angle. It also has a very low input lag which is perfect for gaming. It is also significantly cheaper than the competition.

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
Gamma: 2.2
Backlight: 35
Brightness: 50
Contrast: 80
Color: 54
Tint: 0
Sharpness: 0
White balance:
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.

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.

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).

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.
Jul 11, 2013
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.
Nov 11, 2013
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.
Dec 18, 2013
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 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.
Feb 20, 2014
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).
Mar 17, 2014
Can this LED connect to the Hi-Fi system?
Yes, via the Digital Optical Audio Out.
Nov 23, 2013
Does the LG 55LN5400 actually have a headphone jack?
No it doesn't.
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.
Sep 12, 2014
Can I use a Wi-Fi dongle to convert these TVs into smart tv?
No, but you can buy a ChromeCast or Roku Stick.
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.
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.
Feb 26, 2014
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.
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.
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?
No it doesn't. The 42LN5700 does though.
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 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.
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
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.
Feb 09, 2014
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.
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.
Nov 25, 2013
42LN575S is the same as 42LN5700?
Yes, it is equivalent, but for a different country.
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 30, 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.
Jan 07, 2014
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 07, 2014
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.
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.

Mar 26, 2014
What energy saving setting should I use? Auto, off, minimum, medium or maximum?
The energy saving setting changes the luminosity of the backlight depending on the amount of light in the room. If you want full control of the luminosity, you need to disable that setting. Otherwise, set it to highest you can without diminishing your experience.
Jul 20, 2014
I just bought LG 50LN5400, when plug in the usb, not all pictures can be view on the tv, although they all are in the same jpeg format. Could you help me?
There are probably not actually in the same jpeg format. There is not a single jpeg format, even if they all have the same extension. It is probably because some of them are encoded in progressive. Check your files encoding and see if there is any differences.
Aug 17, 2014
What year was the LN5400 manufactured?
Sep 23, 2014
I have a 60LN5400 and I think there's a problem with it. When the picture is moving horizontally, I see many dark vertical lines. The best way to see it is when watching a hockey game. When the camera is moving from a side of the ice to the other I can see the vertical lines. I don't really see them when the image is not moving. Do you think it's normal or I should call LG?
This issue is very common and is called the dirty screen effect. Unfortunately, there is nothing you can do about it... It is especially present on a lot of low end LG TVs.
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 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.
Jan 01, 2014
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).
Jan 06, 2014
Is it the same input lag for the 42LN5400 and 50LN5400?
Yes, size is not a factor in input lag.
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.
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.
Mar 11, 2014
How good is it to watch sports/football/soccer on this tv? Some people claim that TruMotion cannot be turned off?
This TV has slightly more blur than the average LED. On the unit that we tested, the TruMotion settings was grayed and always off.
Mar 25, 2014
To be clear my Xbox one and PS4 running through hdmi will play at 120hz or is it as needed by the game?
No it won't. Xbox One and PS4 games are either at 30fps or 60fps (depending on the game).
Mar 29, 2014
Which TV is better and how much is the difference (50LN5400 vs 50ln5310)?
The picture quality is about the same.
Mar 30, 2014
Would you recommend using dynamic contrast for gaming?
Dynamic contrast changes the backlight luminosity depending on the content of the picture. We personally always disable this option, especially for direct-lit TVs like the LN5400. It doesn't really improve the picture quality.
Apr 01, 2014
I'm curious about what you do with the tv after you get done testing it and if you think the question is to personal or what ever you ain't got to answer it I have just been wondering.
Usually, we resell them as used.
Apr 08, 2014
Can this LG be calibrated to a good representation of rec 709?
Unfortunately, we do not test for this. We only do a simple 2 points gray scale calibration with a basic colorimeter. Most people don't get their set calibrated (especially in this price range), so we try to represent that, but still do a basic calibration to have valid photos.
Apr 14, 2014
The LN5310 model is it identical to the model LN5400?
It is closer to the LN5300.
Apr 28, 2014
Is this TV able to connect to Apple TV? I cannot seem to get Apple TV to be recognized when plugged in through HDMI.
Yes, all TVs with HDMI can connect to an Apple TV. Make sure to select the correct HDMI input with the remote.
May 10, 2014
I have the 47" ln5400 and just moved to Germany from the US, however I can't seem to get the TV to switch to PAL. Any suggestions?
Most US models don't support it (we haven't test it on the LN5400 though).

Can I connect my HTC one phone to this tv wirelessly and playback video?
Jun 09, 2014
If the LN5400 is 120hz and the LN5300 is 60hz, why did they score the same in "Motion Blur"?
The refresh rate is not an indication of motion blur, especially for console video games where the frame rate is the same on both.
Jun 12, 2014
Thanks for the review. You made it clear that the LN5400 has considerably lower contrast than the other brands. So if I will be watching TV mostly with lights on (and possibly dimmed), the lower contrast will be less of an issue? Based on your test results the LN5400 has like 3x less contrast than say Samsung, which seems to be a big deal. Thanks in advance for your advice!
With a few lights on, the contrast is not an issue. However, keep in mind that it also reflects more lights than other LEDs.
Jun 17, 2014
I just bought LG 42ln5400, is there an optical sound output available?
Yes it has that output.
Jul 17, 2014
The LN5400 is it a digital tv?
Yes, all TVs nowadays are digital. Only old CRTs are analog.
Jul 21, 2014
Regarding the 120hz, if I hook up my PC to this and play, say Battlefield 4, will I get the 120hz? It's an unusual setup but it is deciding for me between the LN5300 and LN5400. Btw my PC can take me up to 120fps so it does matter. If you also have any useful info that could have me choose between them that'd be great.
No, it won't work, at least officially. No TV officially accepts 120fps, even the high end ones. Unofficially is a different story, but we can't help with that because we didn't try it.
Aug 13, 2014
I too am in the market for a new TV. I have my decisions down to two. Both LG. First the LG 50LN5400 and the second is the LG 50LB6000. My questions are what are the differences between these two models as I only see the LN5400 model on your site. Another question I have is what is the input lag difference between the two models? I understand this site is busy but I appreciate any help and advice you can give me. Thank you for your time and information.
We haven't tested the 50LB6000 so we don't know its input lag. But we don't actually expect a big picture difference between the two. The only differences that we expect is a different bezel. Note that for the 50LB6000 has the same price currently as the better equipped 50LB6300.
Aug 17, 2014
I have an LG 47LN5400. I cannot figure out if I can hook an HD antenna to this television w/o a box...
Yes you can.

Walmart has the 55LN5400 advertised on for $598. When I went there they pulled out a 55LB5900 and told me that is the 55" LG they have - same price and SKU number. Which is better, LN5400 or LB5900?
Picture quality should be very similar, so just get whichever one is cheaper.
Sep 09, 2014
It seems that stores are carrying less and less of these. Should I not buy the ln5400 now, in case I need it replaced by warranty in six months and it is no longer in stock anywhere? Is this a risk I should be considering before purchasing this model?
That model is indeed discontinued. Don't worry though. If you need a replacement through the warranty, they will give you an equivalent and more recent model instead.
Sep 09, 2014
Is this TV 3d?
No it isn't.
Sep 19, 2014
What black level and backlight setting do you recommend for gaming on ps4 in a dark room?
Don't touch the black level setting. This is just a remapping of the range of the HDMI. It doesn't affect the real black level. The backlight setting is really a personal preference. We calibrate for 100 cd/m2, which is good in a dark room, and the resulting backlight value that we got was 35.
Sep 27, 2014
What does the motion eye care setting do? I saw another question about the black level setting. I know it don't change the black level the tv outputs but should it be set to high or low for gaming? When it's on low, it blacks out some objects that can be easily seen on high.
Motion eye care change the algorithm of the backlight flickering. Set the black level to low. If you want to improve the visibility of the shadows, change the gamma setting.

I have an old nvidia graphics card quadro fx4600. How can I connect to my lg ln5400 because the card doesn't have any hdmi input, it only has a dvi input.
Get a DVI to HDMI converter.
