Next-generation gamers demand the best graphics and the most awesome experience. LG Gaming TV puts the game up on the big screen where it belongs, in 2D and now 3D, with up to 1080p/240Hz quality and features like Dual Play, which gives two players a different full-screen view at the same time in 2D.

*For a small percentage of the population, the viewing of stereoscopic 3D video technology may cause discomfort such as headaches, dizziness or nausea. If you experience any symptoms, discontinue using the 3D functionality and contact your health care provider.



Sized just right for the bedroom, this LG TV delivers an exceptional HD viewing experience. And features like Clear Voice II for clear dialogue even at low volume plus a customizable Sleep Timer make LG Bedroom TVs a perfect fit.

What People Are Saying

Rated 1 out of 5 by from Panel Failure Like all the other posts, we had the TV for just over a year and it went black. Warrantee or not, if LG knows these TV's are failing like this, they should do something to compensate.

Rated 1 out of 5 by from Loved it until the HDMI ports failed The picture quality is great and we were very very happy but after less than two years of little use (it is in our vacation home) neither of the HDMI connections work. HDMI 1 stopped working and less than a month later HDMI 2 died as well.

Rated 1 out of 5 by from LED Backlight died after 14 months LED Backlight went out 14 months after a purchased it. This is the second LG TV in last years that died on me. Luckily, I purchased a extended warranty.

Rated 5 out of 5 by from Great quality at great price Picture is bright and clear, very sharp. I have an antenna for local stations that is run through my computer and Dish satellite service. So, I have to use 2 of the inputs and both work beautifully and are easy to switch between. I wanted a 42" screen and they were hard to find. LG had one and I will go to them first the next time I buy this or any electronics or appliances. Pricing is very competitive and reasonable.

I have a 50LN5400 and the picture began to flicker in the upper left (while looking at the front of TV) and now there is no longer a picture, just sound. Is there a fix for this or not?

Asked by: Oyoklk
We regret the inconvenience you have experienced with this television. If the picture has gone out, yet the audio can still be heard, then there is likely a problem with the screen, a video driver, or another related component. The TV will likely require service.

Are there any other TV Stand Base Options that will fit/be compatible with this TV?

When I got this TV, the stand had been long discarded as it was Wall Mounted. I have found the correct stand for this model online, but I don't like the look of it. What other LG TV Stand/Bases will fit this TV? Thanks

I am considering the 50LN5400 LED TV, and am wondering about the sound. It will be placed diagonally in the corner, and with the speakers in the rear of the set, I am concerned about an echo or revert effect. Should I also consider a soundbar for this TV? Recommendations?
Asked by: Ellen1961
I bought the LG soundboard and wired sub.    120 watts, sounds awesome TV volume up or not.  Nice TV though,  I love the LGs color and blacks are produced nice on this set.

Why is there no program information displayed?

I purchased this 60LN5400 to replace an older and smaller LCD Samsung. The Samsung displayed program information and the EPG on all ATSG channels. This LG does not show any program info and the reception doesn't seem to be as good as the Samsung either. They were both connected to the same coax exactly the same way. The picture is excellent and I am pleased with the television overall. Please tell me how to get the program information displayed on my LG television. Thank you, Harrel Lamkin
Asked by: MrHorsepower
Hi Mr. Lamkin. Thank you for your inquiry. Not sure how much older your previous TV was, but much has changed since the advent of Smart TVs and Cable Set Top boxes got more interactive and sophisticated. It used to be that some TVs came with Electronic Program Guides built into them, but nowadays, you will not find those on TVs like the LG 60" Class (59.5" Diagonal) 1080p LED TV, Model # 60LN5400. Electronic Program Guides are a feature that is now found on Smart TVs or from your Cable Set Top Box. If you're using an external antenna, you would have to get one that has that as a upgrade feature...^IFV
