LG 55LN5400 Review

55 Inch 1080p LED edge Lit LCD HDTV 120Hz

by , Reviewer

LG 55LN5400 LED TVThe 55 inch TV is a very popular size. The 55LN5400 will be quite the hit for those not interested in have a TV with 3D capabilities. To take it one step further, it has no Smart TV features either. What it does have is a full HD resolution picture with a 120Hz refresh rate. That should be music to the ears for people not jumping on the internet and 3D wagons. It resides at the top of the heap of TVs that forgo these extras, so it will be quite competitive with TVs from other manufacturers that leave these features off as well.


  • Ecxellent value offering for screen space and picture quality compared to competition
  • Direct LED backlighting creates bright colors and strong contrast
  • USB media player can read many different formats for playing content on the TV
  • Thin bezels make this an attractive TV


  • Only 2 HDMI inputs may not be enough for some
  • Smart TV and Magic Remote are left out on this one
  • Off center viewing leads to loss of color and contrast at 25 degrees
  • 120Hz Trumotion should be disabled for shows and movies


  • Glossy black plastic stand
  • No cinema screen design – wider bezels and profile
  • Sound quality provides room filling volume but somewhat flat sound

    Picture Quality Rating: 8.3/10

    Direct LED Backlighting - Very Bright

    The LN5400 series, like the 5300 below it, is a direct lit LED TV. This keeps the cabinet to from being very thin like a lot of the top tier LEDs from LG. This type of backlighting still produces the same bright and colorful images as the edge-lit variety. Screen uniformity performance can be better with this style of lighting as well, even if it is minimal. Like all LED TVs, backlight levels are key to getting the best screen uniformity. A simple adjustment to reduce the back light brightness should take care of any uneven uniformity issues.

    Side Viewing Angles

    This is yet another stigma consumers have to deal with when it comes to LED and LCD TVs. Historically off angle viewing has been rather bad, but we can see slight improvements. The LG 55LN5400 starts to see contrast and color degradation around the 25 to 30 degree off center mark. This is nowhere near as wide as some of the top tier models or plasma TVs, but it is more than acceptable in our book for an LED TV.

    Trumotion 120Hz Refresh Rate

    It is nice to see a 120Hz panel on the lower end of the lineup. This feature excels at reducing motion blur and has been a solid performer on past LG TVs. In the LG 55LN5400 it works just as well. Motion blur and judder have always been known to be a problem for LED and LCD TVs. When this feature is enabled it does a decent job of keeping the two in check, though not eliminating the issue completely. Trumotion can also be turned off if any unwanted effects arise from the feature being enabled.


    If gaming is a major concern on your list while TV shopping, the 55LN5400 may not be what you are looking for. This one did not receive the upgraded GPU and dual core processor that the Smart TVs of the lineup got. This is going to be an issue for motion blur and judder. We even saw those problems on higher tier models. The Gaming picture mode is extremely handy for taking care of input lag. This is going to be the biggest concern, and the LN5400 delivers. If judder and motion blur are not problems, than this is going to be a decent choice. The rating for gaming is a 7 out of 10.

    Features Rating: 7.5/10

    Connectivity Features – Digital Libraries have a New Home

    The LN5400 may only have 2 HDMI inputs, but it has a few connectivity options for playing back content from other sources. The single USB port is located on the side of the TV and accepts a large variety of formats to cover just about any digital movie, show, photo, or music you can throw at it. The accepted formats are: DivX HD, JPEG, JPG, MPO, AC3 (Dolby Digital), EAC3, HAAC, AAC, MPEG, MP3, PCM, DTS.

    There is also the MHL (Mobile High Definition Link) option for connecting smartphones. This requires a special cable that is able to transfer data at high rates for playing back high definition audio and video.

    Appearance - Very Simple

    The 55LN5400 series does not implement the Cinema Screen design, so it misses out on invisible bezels and an extremely thin profile. The direct LED lighting adds some depth to the TV, so keep that in mind for wall mounting. The depth without the stand is right above 3 inches. The black plastic bezels measure in at half an inch. They have a brushed texture that give off the appearance that they are metal. This one manages to keep a nice subdued look without grabbing too much attention.

    Sound Quality

    The lower end LG LED TVs don't have the same great speaker system as TVs like the LA7400. We think those TVs have some of the best on-board speakers on the market right now. The 55LN5400 features 2 one-way 10 watt speakers instead of 2 three-way 12 watt speakers. That makes a big difference. Volume is good on this TV, but the range of sound is empty in comparison. LG's different sound modes and Clear Voice II feature really helps round out the sound to make is more than tolerable. Sound quality scores a 6 out of 10 on the 60LN5400.

    Value – Bang for the Buck Rating: 9.3/10

    The 55LN5400 occupies a very unique spot in the 2013 TV lineup. There aren't any direct competitors for the 55 inch size class that offer the same feature set. This one can be found for less than $900. This makes it a very strong value offering for the size. Similar TVs include the Samsung UN55F6300 and the Vizio E551i. Those both feature internet connectivity.

    Overall Rating: 8.4/10
