LG LN5700 LED TV Review

Reviewed Aug 02, 2013

The LG LN5700 LED TV has the same screen as the LN5400, but is equipped with Smart TV features and motion interpolation. The viewing angle is great, but the contrast and black level is sub-par.

7.1
Overall
  • Great viewing angle for an LED TV.
  • Average amount of motion blur for an LED.
  • Average input lag. Most gamers will not notice it.
  • Low contrast. The blacks will appear slightly gray in a dimmed room.

Dark Room

Black: 0.140 cd/m2
White: 100.2 cd/m2
Contrast: 716 : 1

The contrast on the LN5700 isn't good, which results in grayish blacks. This TV isn't the best option in this price range for a dark room (the Samsung F5500 performs a lot better).

Viewing angle: 37 °

The viewing angle on the LN5700 is really good, without any discoloration. Half the maximum contrast was present at 37°.

LG LN5700 Uniformity

The uniformity is average for an LED.

Bright Room

Reflection: 3.3 %

The LN5700 is better suited for a bright room. The amount of glare is slightly higher than average, but it shouldn't bother you unless you have a lot of windows in your room.

The details are more visible with a bright scene.

Video Games

The motion blur is slightly worse than the average LED.
It supports 24p playback without judder and it also has the option to turn on the soap opera effect.

The input lag is more than the similar LN5400, but it shouldn't be noticed by the majority of gamers.

I have a 42", how do I turn off the trumotion? It makes everything look like a soap opera.
Deactivate the option TruMotion in Picture->Picture Options.

I've tried Trumotion at various settings but the tv still shows 60hz on a channel when I press the info button on the remote. How do I get 120hz?
This is normal. The TV is displaying the input frame rate, not the interpolated frame rate. It will never display 120Hz on the input, because it doesn't accept such signal.

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.

For the LG 50LN5700, how do I reduce motion blur for gaming? Are there settings that I can use?
Not really. The TruMotion setting does help with the perceived amount of blur, but it can't be used in video games because it adds too much input lag.

I am very confused. Is this a legitimate 120hz refresh rate panel? I see contradictory information everywhere.
Yes for models 42" and higher. The 32" and 39" are only 60Hz.

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 input lag on the Samsung un40f6300 when the game mode setting is turned on? As well as what is the input lag on the LG 42ln5700? I was also wondering which provides a better picture quality because I have heard both sides.
Our measurements of input lag are with game mode turned on (62.5ms for the F6300 and 66.6ms for the LN5700). If you are sitting directly in front, the F6300 has better contrast and motion. The viewing angle is very narrow though, so if some of your viewers are at an angle, the LN5700 is a better choice.

Just bought the LG 50LN5700. I am very disappointed in the audio. I have tried the obvious online settings for different modes but none are satisfactory. Any suggestions?
We didn't test the audio on it (we will most likely start testing audio on next year models). As a rule of thumb though, most TVs nowadays don't have good audio due to their thinness. They are OK for day to day TV shows, but if you care about sound, you need to invest in an external audio system. Even basics sound bars beat most TVs.

I would like to connect the LN5700 to my modular Sony Genezi but it only has RCA audio input. If I connect it to the headphone output instead, would it be the same quality as the Digital Optical output?
It will work but it won't be the same quality.

I saw an LN5790 at BJs Wholesale. It comes with a sound bar which seems like a good deal IF the LN5790 is the same as the ln5700, with the addition of the sound bar. Can you confirm this?
Yes it is.
