    • Amazing Picture and features
Size: 65 Inches Style: TV Only
Super nice TV. I got this to replace my LCD TCL and I do not regret it. Color saturation and blacks are amazing and super clear. Can't recommend this one enough. And if you use an Apple TV it integrates seamlessly - Magic Remote worked without configuration, and there are new options in the ATV picture setting for Dolby Vision, aspect correction, and a few other things I did not have previously. One feature I love is the screen off function - you can just listen with the screen turned off. Of course you get the whole LG WebOS built-in too. ... show more

    • Another great LG OLED
Size: 65 Inches Style: TV Only
I have been a LG OLED owner for 10 years now. Our first one did have a board failure but it was the 1st Gen and curved. Our 2nd LG OLED was slightly curved and is going strong for over 6 years. I bought this one because of the huge price decrease. When I bought my 2nd OLED in 2019 the 55" was $1600 and the 65" was $2400, this got down to less than $1k and it was a no brainer to buy, even though I didn't really need it. This one is not as bright as the C series (or G series) but all the features are there, I don't need the high refresh rates as I'm not a huge gamer but more of a movie watcher. OLED is the best TV you can get now for picture quality and the blackest blacks. Smart TV features are good and work well (better than an AppleTV) and I'm actually one that likes the magic remote function that works like an air mouse. Inputs and outputs on the back of the TV are well placed and offer just about everything you will need including an optical audio output, which is a must for me. ... show more

    • Hard to believe this is entry level OLED!
Size: 65 Inches Style: TV Only
Review Image by michaelb1968 michaelb1968
This is my first OLED TV and I almost didn't buy it because of all the "entry level" chatter. I watched a few detailed reviews though and they all said the same things, which is that the TV is awesome, but there are others that are extra awesome and a lot of extra money. I am so glad I went with this. For starters, the picture is flat out sick. I cannot believe the difference between this and my other non-OLED 4k TVs. I am going to wind up going broke replacing them. The blacks and darker scenes are so crystal clear and perfect, no ghosting, no scaling, it is just perfect. What really knocked my socks off though were the 2 things that people were lukewarm on, and that is the sound and the remote. I included the pic to show the size of the room. I am standing 10 feet behind the sofa. This is an open floor plan with a bigger space than the picture shows and this TV fills not only the room, but the entire first floor and then some. The AI sound feature absolutely rocks! I swear it is equal to my Sonos Play 5. You can google cast to the TV too which is great. As for the remote, it is awesome. Sometimes the pointer is nice, but if you don't like it just don't activate it. The modes are seamless. Voice activation is great and you can search inside apps, not just outside. It has good weight and feels nice in hand. Total winner. LG Web OS is super fast and easy to customize. The LG Thin Q app is also nice and double as a remote. Setup was simple. I just don't know how anyone could not be happy with this TV. ... show more

    • My Experience with this OLED TV
Size: 65 Inches Style: TV Only
Pretty decent display. Only issue I have is the glare/reflections on the screen make it difficult to watch. The glare causes eye strain. I would buy a different TV with less glare/reflective screen. Other than that it works great and the picture is clear. I dislike the webOS installed on the TV when you first set it up Chanel’s start showing different content from different vendors to try to sell you their subscription service. The only way around this is to set the TV up to boot into one of your input devices. Another issue you might face is, if you are worried about the screen, being scratched slight bumps with anything that might be kind of sharp will scratch the screen due to it being some type of soft plastic. And lastly, the screen clearing function. Before the TV fully shuts down, it will go into this pixel cleaning process. It takes about 5 to 10 minutes/ using 30ish watts across that time. (No image burn in, well over 700 hours on the set) Tv operates anywhere from 100watts to 200watts based off screen brightness. Over all I do like the TV the only thing I don’t like is the eye strain from glare on the screen/lamps/windows/reflections. ... show more

    • LG B4 OLED is awesome!
Size: 65 Inches Style: TV Only
I've had this LG B4 OLED for about a week. Upgraded from a Hisense 65R6G UHD, this is my first experience with OLED. It's an amazingly better display, simply beautiful. My old tv was Roku based and this LG has webOS and I'm adjusting to and liking the change. So many more settings on this LG and lots of free channels, just like Roku. I use an indoor over-the-air antenna and it also gives me over 100 free channels. All the apps work fine and were easy to sign into. I use my Bose headphones daily and I love not having to use the Roku app on my phone to connect my headphones to the tv. The LG has Bluetooth built-in, so now, when I turn on my headphones, they automatically connect to the tv. It has built-in Alexa but I haven't enabled that. Use can just use the remote to voice control the television. My wife even admitted that this LG's picture looks way better than what we had before. That's a great endorsement in my little world. I bought the 3 year warranty (always buy a warranty, it's reimbursed my television cost, two times in a row) and with tax, I paid $1185 total. This is an entry-level OLED television and the key word here is OLED. I'm loving it so far. ... show more
