What People Are Saying

Rated 4.8 out of 5 by 216 reviewers.
Rated 5 out of 5 by Awesome 3d smart TV! The LG 55LA7400 is an awesome set. 3D Blu-ray Discs look absolutely stunning and the 3d depth is amazing. My wife and I chose this particular set on the specs and overall picture quality, but also because it was one of the ability to convert regular shows and video games from 2d to 3d, a feature that was only available on a limited number of TVs. After watching some of the Stanley Cup playoff games in 3D, I'm hooked! This is definitely one of the most complete passive 3D Smart TVs on the market, and a great value for the price. Thanks, LG!!!

Rated 4 out of 5 by great purchase Love this tv, easy to use, awesome definition and overall quality. I wish that it wouldn't have a sticker on the screen - top left - that leaves some glue behind when you remove. May 1, 2014
Rated 5 out of 5 by Great for Movie watching! It's right up there on top with the Samsung and Sony. May 31, 2014
Rated 5 out of 5 by This product is amazing I had been looking for a new television for an upgrade. After looking at different brands I fell in love with the la7400. I was blown away with the amazing picture quality and how bright all the colors were on the screen. The 3d feature is absolutely amazing and I was blown away by how clear and life like the 3d picture quality is. The magic remote is the coolest remote I have ever owned. It's easy to use and it's sleek design allows it to fit into anyone's hand. I am really happy with my tv and pleased with its performance. Thank you LG. April 15, 2014
Rated 5 out of 5 All around Great TV Love it! Great image, the smart features work great, sound is great. Like I said, it's great so buy it if in doubt. April 14, 2014
Rated 5 out of 5 by STUNNING ! You will not regret this purchase. Everybody just can't get over the picture ! LG has yet again put out a incredible product ! I researched for a long time before I bought. This TV does so much and is very user friendly and not hard to use at all. You can shoot a youtube video from your PC right to the TV or use Smart Share and shoot your PC to the TV among many many things this TV can do. Ton of APPS all ready built in,Netflix, Hulu, etc. Also has a web browser. Just does too much to list. Very Happy Happy Happy April 14, 2014
Rated 5 out of 5 by LG continues to impress! Our first LG product we purchased was a television back in 2009. we simply loved that television I forgot the model number but it was a great tv. We purchased the 55LA7400-UD as a christmas gift to ourselves and, I must say the features along with the sleek design, picture quality, smart and 3D capability but, to me the coolest part is the smart remote. LG has indeed stepped into the realm of big name electronics manufacturers and I thank them for a great product we are definitely satisfied with our purchase. Thank you LG my TV Rocks! April 12, 2014
Rated 5 out of 5 by Great design all around - appearance and functions I am very satisfied with my LG LA7400 3D Smart TV.. The picture is great (once I set it up carefully), the audio is surprisingly good, and the set has a sleek appearance. LG's software makes it easy to calibrate the picture. The small remote with a minimum of buttons was a pleasant surprise. Connecting the smart TV to my wireless internet was a breeze. Well done, LG! May 19, 2014

MATTE or GLOSSY?

Answer: 
The screen is glossy. However, it is not as bad as a plasma TV. I have not noticed much reflection, but I have found with higher quality TV's it is better to have your lights behind the television. I would not let the gloss screen deter you from this purchase, it is a fantastic TV

Answer: 
Glossy, so I don't recommend you place this tv in direct sunlight. The glare is terrible. We just close the blinds near the tv during the day, the picture is great!

Answer: 
That number is total irrelevant as each brand creates his way of measuring the contrast ratio. As you no there is no standar to apply to all TV brands to measure that. What do you need is to go to a store a see the picture your self. Take one or more DVD/Blu-ray and play them and see for yourself.
With this TV you have so many tunings that I even had used them all.
You can tune the darks and the whites separately!

Hope this helps

Answer: 
It used to add much more to the price. I've seen it drop though in the passed year. It is a great feature when playing blurays.

Answer: 
120 hz runs around 999 for this size tv, 240 hz is 1499. It is worth the difference in price for 3d tvs.

If I have an Intel WiDi-enabled laptop, can I connect to this TV and use it as a dual screen without connecting it with a wire?

It says on intel's website that all 2013 LG TV's support WiDi. Is this true? If so, would I not need an adapter like the NETGEAR Push2TV adapter to connect with it?

Answer: 
Actually you do not need any extra equipment. I didn't realize the tv had this feature until a couple of weeks ago. Automatically reads your device.

Answer: 
Hello lgtvninja!
I happened to have the same tv and yes, you should be able to connect via WiDi ( wireless display) as long as both devices are on the same network. Open the program on your laptop and look for the device, once it finds it then a prompt will be displayed on the Tv; after you accept the laptop screen should come on. FYI image may be not as expected since most laptop has less resolution than the tv, but should be enough. Have fun!
