Inspiring design with great features.

Submitted by Brasilcat - 5/20/2018

I have had this LG TV for 4 years now. I love the features and functions of my TV. However a flawed power supply is not representative of a quality product. Power supply are simple and have been mastered for many years by electronic manufacturers

Best TV of 2017

Submitted by DT45 - 12/12/2017

LGs 2017 OLED models are brighter with clearer pictures better sonics and improved designs. The E7 occupies the sweet spot in the lineup and IMO you can spend more for different design features e.g. the G7 or the W7 but why would you? Im especially impressed with the way this TV upscales ordinary HD broadcasts - sharp and clear with no artifacts I dont have access to 4K streaming - Im sure it would look even better. I use the sets Active HDR with DolbyVision feature to improve the HD picture even more - it really works. Theres more detail in darker areas of the picture compared with previous years models. And the Dolby Atmos sound is terrific - I dont feel the need for an extra sound bar. I also appreciate the way in which LG improved the E7s design to make it easier to move around and position. Cant think of any real negatives at all. And with the year-end sale pricing from LG I dont think you could go wrong. Buy this one

Expensive TV that wont pair a set of headphones.

Submitted by Vjohn - 11/26/2017

I cannot believe I spent this much money and the LG TV will not pair to a new bluetooth headphone set. I called support and they said it may or may not. Well it did not pair. Unbelievable. I will not recommend nor buy another LG TV.

2 Year Lifespan

Submitted by TVSadness - 11/9/2017

I purchased the LG 55EC9300 OLED in October 2015. In the beginning of October 2017 it began displaying wide vertical band and partial screen freezing. A week later it powered itself off during operation and never came on again. Research into this problem revealed it to be a fairly common one. A television at this tier should last longer than 2 years. I am extremely disappointed in this product and regret my purchase.

OLED can suffer from burn-in screen damage

Submitted by NeverCNN - 10/17/2017

During the period of the last Presidential Election season I had my set tuned into CNN for long hours each day. Due to CNNs practice of constantly except during commercials displaying their large CNN banner across the bottom of the screen I discovered that now many many months later I still have that banner burned into my screen. There is no cure for this damage. I was aware of this problem with CRT monitors and TVs but I failed to notice the cautionary mention of this issue in the Manual provided with my set. I ca see why gamers would be well advised to steer clear of this tech if they plan on using it to play hours of video games in lengthy sessions. I failed to realize until it was too late that any programing practices like those of CNN could cause irreparable harm to my investment. As a result this set is no longer EVER tuned into any live or used to play any DVR programming from CNN. I will forever have a pale yellow ghost of that image with all my viewing.

Life is really good with LG

Submitted by Sathiesh stanley - 9/22/2017

I got this oled tv a year ago. Within 2 months the tv stopped working and i was disappointed and had a thought if i made a wrong decision. Thats when LG service came and ensured that everything was taken care.They changed the oled panel and fixed the issue. From then on i always felt with LG i m in safe hands. Now about the tv. DesignAmazing picture quality easy connectivity. Now the cons of the product sound quality is not good with internal speakers webos interface is slow power button could have been made simple rather than having a joystick kinda module. Store executives and installation people need to know that 3d works with glasses post removing the plastics from the screen when its new. This is just a feedback bcos i was told that 3d is not supported and that some module is faulty later a senior lg tech removed the plastics and got it working. Overall lg is awesome and i feel happy and proud to be its family member. Thank you Sathiesh stanley
