best tv ever

Alycia H 6/20/2024

We had an older model 55 inch smart tv and we upgraded to this LG B4 77 inch TV It was a necessary upgrade to our living room tv This TV has blown us away from the lightning fast tv easy connectivity and the image on it is indescribable. I think Ive seen colors on this TV so clear that I will never be able to see another way. All the details are hit with this LG TV its sound is impeccable that it doesnt even need a sound bar. I call it a TV that can turn your living room into an at home movie theatre. The always ready mode is something I wasnt expecting and is a phenomenal touch It can show pictures and do white noise at the same time and you can customize it however you like. From the picture processor sound and features you get with this TV it is more than the bang for your buck and If I could give it 10 stars I would cause it is the TV your living room needs Review submitted as part of a program that provides a purchase discount

Best TV I now own

Ruben V 6/5/2024

I bought this TV about a week ago and its honestly awesome. The sound and picture quality is amazing and its got this AI thing that adjusts how everything looks and sounds to make it even better. I was blown away by the fact that I can play video games straight on it without any extra console. My first time having an OLED TV and the difference is huge the colors are so vivid and everythings super clear. It runs on WebOS24 and Im still figuring out all it can do but its been a fun journey. After getting used to this I dont think I can go back to regular TVs. If youre thinking about switching to OLED Id totally recommend this LG TV. Its changed how I enjoy my movies and games big time.

An absolute must have

Taylor C 6/3/2024

This was my first TV upgrade in years. I went with the 77-Inch Class OLED B4 Series TV I loved that it had webOS 24. It was super easy to set up with the stands but I also have the option to mount it. The point and click remote makes browsing apps and shows a breeze. I couldnt believe how thin it was when I set it up I didnt think it was possible to have a tv be this slim. The picture quality and audio is top of the line and for the price its bang for your buck. It looks super chic in my living space and I get so many comments when people see it in action.Review submitted as part of a program that provides a purchase discount.

Better then going to the movie theater

Stephanie D. 5/18/2024

This tv has the best picture quality I have ever seen Its even better than watching a movie at the movie theater I was worried because I have so many windows in my living room that it can be hard to see any details with our old tv but everything looks so crisp and clear on those dark scenes with this amazing tv.

literally have a cinema at home

Priscila F. 5/16/2024

Im here today to give my review of my new 77-Inch Class OLED B4 Series TV because Im in love. I loved most is how convenient it is to control the point system and scrolling moves the cursor on the TV instead of having to click every individual thing I was very impressed with the quality of the image and how the colors become so real truly incredible. Now we literally have a cinema at home we paid a great price for the quality of the TV. I was surprised at how thin and light it is compared to other TVs of this size The TV came with feet which made it very easy to install in our living room and fit perfectly. definitely 10 out of 10 very happy with my purchase
