Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy, and expensive and you probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Excellent picture quality and graphic performance

Submitted by SraShou - 12/14/2020

Was debating between a 55 and 77 inches OLED TV. I am glad I decided to buy the 77 inches LG OLED GX and wall mounted it. The graphics performance and integration with other services viz. Netflix Amazon Prime Apple TV etc. is exceptional. Strongly recommend this product.

It fit the space better than I thought

Submitted by Longview1002 - 12/2/2020

Ok this is a new TV for a new house to me and I had to have it mounted over a gas log fireplace or at least to the side. The thing is large yes but it is really heavy guys. Dont try to do this without some significant pairs around. It took 3 guys to get this thing mounted on the swing-out mount that I bought for it. The mount that came with it looks really easier to do if you have a flat place to mount it. DO NOT SKIMP on the anchors guys or you will come home to regret it one day. Plan your space and hanging process and you will be good with strong help. Wonderful picture easy to find your way around I still cannot get it to run my cable box but I am with a runt organization and they have uncommonly used stuff I think. I hate to read manuals and the onscreen in process help is pretty good. The sound out of the TV is not what I expected. I have it hooked to a 2005 sound system that sounds richer. Go for a sound bar at least. I had too many in family expert advisors to decide on the direction to go so I slung it on the thing that was left with the house when I bought it for now. I want to have the TV remote run everything and I think I know enough now to pick. There was not enough information available to help me in advance...I am techno dumb mind you but I had some real knowledgable audio guys looking and none of the needed specifics were in the online stuff that we could see. I was not able to stay on the phone long enough for LG to give me an answer....go figure. Long and the short I like the TV a lot. Picture wise it is great. Presale info not so much. It will work better with your sound system my bet. Who needs sound for Football anyway

Simply awesome

Submitted by Belg - 12/2/2020

I owned a 65 OLED and always regretted not going to the 77. I had the opportunity to sell my older one and have loved the upgrade The picture rivals the best Color reproduction and well those blacks are just impressive. Fury Roads storm sequence is just breathtaking on this beautiful screen. I need to do a bit more setup though as I did wall mount and believe this will be a gorgeous live wall art display as well as family photos. You cant go wrong but be sure to vary that content as burn-in could still be a long term concern - dont know if theyve solved it with this display. Ive never felt Ive gone wrong with LGs OLED displays though as they simply are the best picture anywhere.

Sound quality

Submitted by BARRY 0708 - 11/30/2020

The sound quality is not acceptable for the price of the TV. Really unhappy Bought 2 of them Bedroom and family room They make a matching sound bar but for the 65 inch Have 3 LG OLEDS in the house. Looks great on the wall and the picture is exceptional. My previous LG G6 was phenomenal.

Submitted by Gina2008 - 10/20/2020

Purchased this for my bedroom and its great. Ive had it about 2 months and so far the picture quality and features are excellent. I do recommend this tv if you are looking. Like most TVs the sound is okay. I use my sonos sound bar instead of the TV sound.

Unbelievable Picture

Submitted by alan0209 - 10/6/2020

I have a OLED 65 that I bought last year. I waited for the 77 until recently and I am so glad I did. I thought the 2019 65 was as good as it gets but my 2020 arrived last week and I installed it yesterday. Images are so real you would think they are in the room with you. I would have purchased it sooner but I was waiting to see customer reviews. I finally gave up and purchased it and I am so glad I did.

Do not buy from Value Electronics

Submitted by David1984 - 8/15/2020

Do not buy from Value Electronics They do not have tvs in stock even when the website says that they do. It is a scam to get you to buy from them and their customer support is awful. The TV itself is beautiful and gorgeous and I couldnt be happier after waiting for it be back in stock and ordering it directly from lg.
