    • 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
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

    • OLED TV is not worth 3x cost of QLED
Size: 65 Inches Style: TV Only
I bought the 65-inch version of this LG OLED TV at the exact same time I bought a second 65-inch TV. Both were going into a newly purchased home. The second TV was a TCL QLED TV. Both TVs are excellent. Only difference is in the cost. After much research, wife and I had decided the picture quality on the OLED TV would be far better, so we paid three times more for it vs. the QLED. The former went in the living room, the latter in the bedroom. In hindsight, we wish we had bought two of the TCL QLED TV. It was $800 less than the OLED yet Its picture quality is just as good. No complaints with the LG OLED TV-- other than the fat price tag. ... show more

    • LG OLED TV Has Good Picture Quality
Size: 65 Inches Style: TV Only
I like the picture quality of this LG OLED B4 Smart TV. This is a smart TV. It has about 100 apps that you can install. I don't like the YouTube app. It doesn't keep a history of the videos that you've watched. If you stopped watching in the middle of the video and you turn off the TV, when you turn on the TV again, you can't continue watching that YouTube video where you left off. Most of the time, you can't even find that video again unless you do a search for the name of the video. There's another annoyance with a News app. Sometimes the picture turns a shade darker when you can see the Play/Pause button. ... show more

    • 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
