Hard to believe this is entry level OLED!
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.

Awesomeness
Beats the socks off my Oder 10 year old LED top of line tv in the day. Only reason I upgraded is that my eyes needed upgraded too. Much more visible and larger picture, backlight viewing is incredible! The Dolby Vision/Atmos effect is awesome! Looking forward to watching sports in 4k. I havenât even touched the surface on what this thing can do, but I will soon. Love the five year software updates it receives, one of the main reasons I bought it. Super easy to wall install using my 15 year old universal wall mounts but needs two people to carefully hang it. Lightweight and amazing to get this kind of picture with such a thin screen? Sound is pretty good, still would be better with a theater addition soundbar or theater surround system that I already have I just havenât hooked it all up yet.

Crisp and cool
This tv is technically amazing and its minimalist look fits perfectly into our living room. We have been avoiding a living room tv for over 20 years but this sharp well designed 4K met all our criteria at a really affordable price.We found the Home Screen and preloaded apps confusing and a bit jumbled graphically but we installed an Apple TV and a small soundbar and this LG songs and shines. Our neighbors recommended an LG TV and we are pleasantly surprised by the quality and simplicity of.

Good picture, fast to change channels and apps.
So far all is working. Remote is good. Hope it will last us years to come. Only time will tell.

Great Picture Quality
sometimes the most expensive tv isnât what you need. Sometimes you just need a really high quality tv that has everything you need and a massive screen. This is what this tv is for. Itâs perfect for us. As a gaming monitor for ps5 adventure games itâs perfect. Obviously if you play a game that needs a higher frame rate you may want to look elsewhere. That being said the ps5 picture quality is amazing on this.

Simply gorgeous and amazingly convenient
This TV is special. In fact, every OLED tv that Iâve come across is special in that the black levels are so incredibly inky-black and this LG B4 is no different. The model letter denotes the level of TV (higher the better, generally) and the number is the year, so this would be 2024âs model. I can directly compare this to the C4 and Iâll say the picture quality is slightly less distinct but itâs still amazing. Itâs a lot brighter than my B8 that I had for over 5 years, one that didnât have any burn in but it did have some dead pixels around the outside edge. They updated the software for a long time and still update the apps, which gives me a lot of confidence in this TVâs longevity. Some other TVâs donât update apps to keep them running smoothly for as long (looking at you Sony) but the OS is amazing. The web browser is outstanding and it blocks a good number of ads that pop up natively. There is so much to love about this TV if you can find it for a good value.What I love:120 Hz native refresh panel that appears to go to 144 for variable refresh. This is outstanding for gamingInput lag is RIDICULOUSLY low (again, great for gaming)Beautiful picture out of the box, pretty calibratedLots of options for picture quality, including an AI option to adjust it based on some pictures you like. Cool setupThe Operating System (OS). So easy to use, laid out smartly, so many options for entertainment whether itâs LG channels to watch tons of content or use the included web browser for a LOT more options.So many options to adjust the picture. Lots of control and advanced options.The magic remote pointer is so helpful and great to use.Setup was a snap, super easy and Iâm getting used to it a lot more than some other brands.Colorâ¦this TV has some amazing color and the picture pops. Itâs beautiful, simply beautiful and I enjoy watching tv just to see how great it looks. Itâs spoiled me when watching in other places, however.2.1 HDMI ports, all 4 are that new standard and can do 4K at 60Hz. Awesome valueThings Iâm not sure about:The stand is made of 2 parts and itâs seemingly got some options regarding how itâs set up (but I mounted mine).You used to be able to bring up an app menu while still watching content. Now you have to go to the Home Screen. A minor annoyance.Things I do not like:The new remote doesnât stand up like the old one. I LOVED that. It took up a lot less space but I get why they did it.They removed the play and pause buttons from the remote and itâs just got the wheel to pause and play. I get why they did it but I preferred a pause/play button.2 out of the 4 HDMI ports are on the back. This is fine for putting the TV on the stand but itâs an awful design for mounting it on the wall. The C4 does not have this issue as all 4 are on the side.This is a great quality TV, itâs got good sound, seamless wifi, and all of the above.Overall, I think this is an amazing TV and itâs their new âentry levelâ OLED but itâs nowhere near an entry level TV. Itâs absolutely amazing if you like deep blacks, the lack of blooming, saving some electricity (individual pixels turn off to make black, unlike traditional or QLED TVâs), love variable refresh rates, low lag for gaming, and want a beautifully operational OS, this is an excellent choice. The B4 and C4 (and even the B8 for that matter) are gorgeous and Iâll never go back to non-OLED if I can ever avoid it. Highly recommend, 9.5 out of 10.

Good entry level OLED TV
This is my first OLED TV, and I am pretty impressed with the great picture quality. However, Iâd probably consider to spend a bit more money to choose C4 instead if I can do it again. B4âs processor is a bit slower, so loading the app or switching the channel is not as responsive as I would like to see.
