The LG LF6100 LED TV has great contrast and black uniformity, so it is a good TV for movies or TV shows. However, its motion blur and high input lag prevent it from being a good gaming TV.
- Great contrast ratio.
- Minimal reflection.
- High input lag.
- More motion blur than average.
- Limited viewing angle.
You will need a wide table to accommodate this TV, because the stand has a foot on either end. Our 50" had a footprint of 40.5" x 10".
2.04" (5.2 cm)
The native contrast ratio is really great - the best we've tested so far this year.
SDR Peak 2% Window
SDR Peak 50% Window
Unfortunately, the gray uniformity isn't as good as the black. The corners are darker and the screen has a few small dark patches all across the screen.
This LG has a VA panel, which means the color shifts when you watch the TV at an angle. The blacks are also not as great off-axis.
Update 01/06/2017: We have changed the methodology of testing. Since this is an old TV which we don't have anymore, we extrapolated the results from 2016 TVs.
The black uniformity is great on this TV. No clouding or flashlighting at all.
This TV has no problem upscaling DVDs. The picture stays sharp, even when 'Noise Reduction' is turned on.
Cable TV after upscaling looks good.
Blu-rays and other 1080p content looks great.
The reflection on this LG LF6100 is average. You can have a few lights on without problem.
It doesn't get very bright, so it isn't the best TV if you have a lot of windows in your room.
The length of the motion blur trail is long. It isn't an issue for movies or TV shows, but it could be for sports or playing video games.

This TV doesn't get loud, but the low-end cut off is decent. The frequency response is good at lower volumes, but it suffers as the volume increases. Pumping may be present.
Total Harmonic Distortion
Acceptable distortion level throughout the range, but the TV doesn't get loud.
The basic remote isn't great for using the smart features, but it does the job.
Power Consumption (Max)
The LG LF6100 LED TV has about the same picture quality as the cheaper LF6000, but it adds motion interpolation (up to 60Hz) and smart features. The contrast ratio and black uniformity are great, but it has too much motion blur and high input lag. It is a good TV for movies and TV shows, though.

Is the 50LF6100
the same TV as the 50LF6090.
Yes. The LF6090 is just the Costco version.
Hello, I purchased the lg lf6100
55" and I have confirmed I have the ips display and not the VA display. I have noticed motion blur during regular tv/movie watching. Would the VA display handle the motion blur any better? P.s I love your site and ratings and have passed a lot of time here. I have bought the following TVs: Visio m50-c1
liked it for movies not for TV watching, Samsung un50ju6500
liked it but had judder in movies. What would you recommend for movie/TV cable 1080i under $1000.00? Thanks you very very much. I was thinking the lg 49UF6700 found at target, any info?
Our 50" VA also had a lot of motion blur, so switching to that one probably won't solve your issue. We haven't tested the 49UF6700. It has an IPS panel, so it will probably score close to the UF7600
we tested. In your price range, you don't have a lot of choice. You could get the J6300
, but it isn't 4k. Other than that, you could spend slightly more for the UN50JU7100
, which would be as good as your previous UN50JU6500
but without the judder in movies.
Will an LG magic remote work with this TV?
No. It only works with the WebOS TVs.
I have an LF6100
. It seems very similar to the LF6000
quality-wise, great black levels, and good gaming performance, but not so great grey uniformity.
That's right in line with what we expect to see when we review it. Thanks for sharing your experience with it.
You say this is a VA panel, but Reviewed says it's IPS and gives it a horrible contrast score. Both of you reviewed the 50". I saw one in Best Buy and I was sure it was VA and seemed like a pretty nice TV for the money. Is it possible that LG is playing the panel lottery with this set and you might get either a VA or IPS panel?
Yes, it looks like there are both IPS and VA versions of the 50LF6100
. We got ours at Best Buy. You can always make an exchange if you wind up with an IPS TV and don't want it.
I just purchased the LG 55" LF6100
one week ago, I view the TV from about eight feet away. I was considering exchanging it for the Vizio M55-C2
, which is about $200 more. 1080p vs 4K. Is it worth it, picture vs price? I mostly watch movies, Cox HD, Netflix, HBO, and some sports.
At that distance and TV size, you'll have difficulty noticing the full benefit of 4k, so you might as well stick with a 1080p set. If you want a better TV for your needs, the Vizio E-series
would be a good buy, as would be the Samsung J6300
I am not able to decide between the Vizio E50-C1
($499) and LG 50LF6100
( $399). The LG is cheap.
I use the TV mostly for TV and online streaming. Is it worth the extra $100 to go for the Vizio TV?
Also which one has easy to use smart features?
The Vizio has less blur, can get a good deal brighter, and has good smart features, so we recommend getting the E50-C1
How can we tell if it's a VA panel or IPS panel on the LF6100
? I purchased the 55 inch because it was in my price range, but I would like the best quality for the price.
The easiest way is to display a white screen on your TV and take a photo from very close. If the pixels look like rectangles, your TV is VA. If they look like arrows, your TV is IPS.
I'm confused, because I am looking elsewhere and this models refresh rate is showing 120hz and here it is showing 60hz. What gives?
LG advertise this TV as 'TruMotion 120Hz' which means a true refresh rate of 60Hz. We agree this is misleading. You can learn more about advertised/fake refresh rate in our article here
When you did the gaming lag test, did you do it with the Truemotion 120 turned off? From its description and experience with other CPU assisted 120 TVs, it tends to cause a lot of gaming lag. I'm looking at getting one of these and would have to return it if I felt the lag in a FPS game.
We take three measurements: one with game mode, one with interpolation on, and one with neither. With game mode, the input lag is 49.7 ms. That's on the higher end of average, so if you're fairly competitive, you may want to pick a different TV. The Vizio E-series
would be a good choice.
Do you have anything to say about the Lg 60lf6090? This is the model carried at Costco and your reviews are for the LF6000
It looks like it is the exact same TV, just with a different model number. This sometimes happens with TVs being sold by club stores like Costco or Sam's Club.
Is there a way to bypass the dimming issues with this model? I heard all LGs do it with dark scenes, and it is commonly referred to as global dimming. The only way I found to get somewhat past it was to set HDMI level to high, which washes out the screen. I know the Samsung J6200
series does this too, but can be bypassed on movie setting.
Labeling the input as PC would help limit the dimming as much as can be done, but we don't think it's possible to get rid of the global dimming altogether.
Would you recommend this LG LF6100
/LF6090, since they are the same or the Vizio E-series
C1? What are the main differences, and overall, what would be a preference? I wish to know which one has the best picture quality.
It depends on what you need to do. The LG has more uniform blacks and better upscaling, so it's a slightly better choice for movies and TV. The E-series
has less blur and lower input lag, so it's a better option for gamers and sports fans. Overall, the E-series is better for more people, but if you only watch movies and TV, the LG is a good option.
Will these 2015 models be eligible for a WebOS update in the future?
Only the ones that originally comes with WebOS, so not this LF6100
I plan to buy the LG 55EC9300
for the living room and I'm buying another set for my office. This after hesitating because the EC9300
will be wall hung in an alcove built for a TV that's 4-5 inches deep. I hope that won't look too strange.
If I get the LG 49LF6300
, then I'll have the same OS and remote, which strikes me as convenient, but that would be at the cost of poor contrast. The specifications of picture provided by the 50LF6100
strike me as better for my purposes, and I can accept the narrower viewing angle. Am I likely to be annoyed by the more primitive OS of the 6100 after using the EC9300? And what about switching between the OS for the LG EC 9300 and those of the Vizio or Samsung you recommend over the LG LF6300
Yes, you might get annoyed by the LF6100
if you use the smart features a lot. Vizio's isn't much better than the 6100, but the Samsung smart OS is really good. For the higher-end TVs, it's almost as good as LG's WebOS, and the smart remote is really good. The lower-end TVs use the same app platform, but the remote is just a basic one.
I just purchased a 55" LG LF6100
TV. How do you get surround sound when watching Netflix on the app mode?
Connect your speaker system, either via HDMI ARC or Optical cable. Open the 'Settings' menu and go to 'Sound' -> 'Sound Out.' Choose 'External Speaker.' All of your TV's audio will now be played through the external speakers.
I purchased a lg lg6100 55" and overall I am very happy with this purchase (although I still miss my plasma). Anything I can do calibration wise to increase the performance of sports viewing?
There isn't much you can do to improve motion blur, but you might want to try the settings that we used here
I received this LF6100
TV with IPS panel (arrow pixels). Is the VA panel better? Should I request to change for a VA panel? Thanks.
It depends on what you want. The VA version will have deeper blacks and a narrower viewing angle, so it's better for people who sit directly in front. If you need to watch from far off to the side, the IPS version will be better. Pick according to your habits.
Does it have a headphone jack?
We are not taking any more questions for this product because we no longer have it in our lab.
