    No issues here picture looks great the price was good the remote works great you get free LG channels the only thing that scares me about OLED televisions is they are fragile... just don't hit the screen this is my second one the first one was a beautiful 65 inch- OLED my daughter threw something at it at some point when I wasn't home and it left very small small mark on the panel which destroyed the entire TV so be careful I recommend highly good TVs

    I bought this to replace a 2010 42” LG TV in my bedroom. I wanted a larger size and had been considering a 55”, but couldn’t find something to fit the quality I was looking for on my sub $800 budget. Purchased this below that price point on-sale. This doesn’t have the brightness of the higher models, but that’s not necessary for my usage where it’s typically morning or night. Plus I can control the light if I’m having a lazy day. I have a 2 year old budget LG in my office. Web OS is a much better experience on the B4, I have to admit I almost didn’t purchase this due to my experience with that underpowered processor. There was some initial slowness in Web OS when I first got the TV, which is probably due to it updating apps and software in the background. Over the next month I have not experienced that with the B4. Mine is in a corner of a 13.5’ x 12.5 bedroom. Audio from the tv speakers is decent, but I’m glad to have a Denon soundbar as I wouldn’t be happy with only the tv audio. This is my first OLED TV and the colors/ blacks are simply gorgeous. I ended up rewatching several episodes of Foundation on Apple TV, which looked phenomenal. The 65” Samsung Frame in my den doesn’t have the same punch in comparison! I’m very happy with this purchase. For my application the model and size is absolutely perfect.

    Amazing visuals - I use it with my PS5 and Nintendo Switch 2 and both look absolutely stunning on this screen. This is the perfect screen for gaming with vivid colors and high refresh rate. The built in speakers actually sound pretty good. I use a sound bar but you could only use the TV sound and still have respectable audio.

    Great TV, it’s OLED so you already know of the nice inky blacks and near perfect color accuracy. Build quality is also very nice, speakers are surprisingly good. All at an affordable price! My only small nitpick is that the power cable is not removable (easily) from the TV itself. Other than that it’s great!

    My 2008 Samsung tv I bought from Best Buy died so after researching televisions I picked this one. I can't believe 17 years ago my old samsung TV cost $1200 compared to the latest and greatest lg oled tv was half the price. I'm not a tv expert by any means I'm just an average joe who appreciates how easy it was to set up, literally plug it in, follow the steps on the screen, connect to wifi automatically and bam your good to go. Every time I would go to best buy and look at tvs over the years I always wanted an lg oled it always looked the best compared to all the others on display. I can't believe I finally got one and I would highly recommend this TV over all the other brands out there as lg has made there name well known for oleds. The picture is crystal clear and the sound is really good. I believe this TV is the best bang for your money.

    This is Big Upgrade from and Led Tv I previously had, This is perfect for my xbox the 120hz and Dolby vision and Dolby Atlmos are features i can now use. I would have gave it a 4.5 review only because if you want to install the tv on the wall as close as you can and use the HDMI Arc Port you can’t, unless you buy a 90 degree HDMI adapter or cable, also you could use the spacers provided in your tv mount which i ended up doing .

    Playing videogames on this TV is such an amazing experience! The 120hz display gives me an advantage in online games, and makes offline games look incredible! The color vibrancy definitely helps as well.

    I picked this up at the $749 price, which is a steal for an OLED TV. I’ve been impressed so far. True blacks, vivid colors. Gets plenty bright, even with my overhead lights on. HDMI 2.1 on all ports and 120hz refresh rate. Movies and games both look fantastic. I highly recommend it. At this price, you can’t go wrong.

    Very good OLED for its price

    I would highly recommend this tv to anyone looking for a OLED. For its price point it’s pretty good quality. It has a really good picture with pretty good colors, it has decent sound for it being a tv and for what I’m using it for it’s a good size. But there’s a few things that I would hit off of it which are the TV being hardwired in so you can’t take out the power cable if it gets damaged or anything and the software is alright. Both are minor things for me as I use an Apple TV on this tv. But I would highly recommend and this tv would not disappoint and make it where you only get OLEDs from here and on out.

    I've had this TV for a few weeks (48" model) and is perfect for my set-up. While the B4 display is not as bright as the more expensive C4 or G4 (based on hardware review sites and when I compared them at the store) it is more than enough for my room. Normally I external device like the PS5 or Nvidia Shield TV for streaming media but the TV software worked better than expected with minimum lag. When playing, games look fantastic and I was able to take advantage of the 120hz mode. Sound quality is good and loud enough but since this is for my bedroom instead of a living room, your milage may vary. The only reason it's not getting 5 stars is the interface and settings does take getting used to and I'm not a fan of remote going into mouse mode like a Wiimote.

    I'm thoroughly impressed with the LG OLED AI TV! The applications run incredibly fast, and the remote's mouse feature is a game-changer - it makes navigating and controlling the TV ridiculously easy. The software is also really cool and powerful. The picture quality is stunning, and the sound quality is impressive too. Overall, this TV is a powerhouse and I'm loving every minute of it!

    I recently purchased the LG OLED Class B4 TV, and it has exceeded all my expectations! The picture quality is nothing short of breathtaking, with deep, inky blacks and vibrant colors that bring every scene to life. Whether I'm watching movies, sports, or playing video games, the clarity and detail are incredible. The OLED technology really makes a difference, especially in darker scenes where other TVs might struggle. The design is sleek and modern, fitting perfectly in my living room, and the smart features are intuitive and easy to use. The webOS platform offers a seamless experience, with all my favorite streaming apps readily accessible. The sound quality is surprisingly good for a TV, but I paired it with a soundbar for an even more immersive experience. Overall, this TV has transformed my viewing experience. It's worth every penny, and I couldn't be happier with my purchase. Highly recommend!

    The Best Value in OLED

    I got a great deal on a Samsung 77" S89C Quantum OLED TV last Christmas, so I was all set for my main TV. But when I saw this deal, I couldn't pass it up. It makes for a perfect bedroom/den/secondary TV. The brightness is lacking, nowhere near the Samsung, nowhere near the G4, and not as bright as the C4, but what you get is an unbelievable value. $600 for the 48" version is unreal. Picture quality is very impressive, the sound quality is actually pretty good. I love that it has Dolby Vision, which the Samsung lacks. I have included a photo of today's game. Happy Thanksgiving, everyone!

    Got this tv to use as a computer monitor. Hands down best purchase ive made. It is a little too big for the distance i sit. But i would have never expected an oled to make video game cut scenes to look like an imax movie experience. I run a 3060 12gb gpu and i know 4k is pushing it past its limits but keeping it at 60fps in game settings i get less screen tearing with this 48 inch LG OLED than i did with a 32 inch Samsung QLED. I will be buying more of these tvs in the future to replace the other tvs and monitors.

    Needed a new flat screen ahead of our kitchen renovation and the LG fit our needs exactly. It’s fast, sharp and bright even against our large windows in afternoon sun. The sound is surprisingly good-better than expected! The remote is easy to work with and is much like the one on our 65” LG in our great room. Software isn’t wonky and there’s so much programming that we probably will never get through. Well worth spending a little more for an upgraded unit. Very pleased. Also very happy to purchase from Best Buy.
