    The LG OLED B4 series is an impressive TV for its price, offering fantastic picture quality and a few standout features, though it’s not without its drawbacks. Picture Quality The TV's OLED panel shines with exceptionally bright HDR performance and incredibly deep blacks, creating a level of contrast that surpasses standard 4K TVs and even slightly edges out QLED technology. Whether watching movies, gaming, or streaming, the visual experience is immersive and vibrant. Build and Design The build quality is solid, albeit slightly heavy. However, this heft translates to durability and a sense of sturdiness. Mounted on the wall with bias lighting, the TV looks stunning and adds a premium touch to any room. Installation is straightforward, and the design feels more robust compared to many competitors. I use mine in a 12x12 room, where it fits perfectly. Additionally, I’ve noticed very little glare, even in bright daytime conditions, making it suitable for a variety of lighting setups. Performance and Gaming While the resolution and refresh rate are impressive on paper, the gaming features fall short in practice. Game Mode and AMD FreeSync didn’t work properly with my AMD RX 6800M GPU, causing the screen to flicker black or shut off entirely. As a result, gaming performance can be hit-or-miss. That said, the TV can function as a decent monitor when it works. I’ve had enjoyable gaming sessions, but the refresh rate never feels quite right, regardless of adjustments. Turning off TruMotion improves performance significantly. Smart Features The TV offers a wide range of apps and integrates seamlessly with Alexa. However, the AI features are underwhelming—I’ve noticed minimal benefits beyond slight sound optimization. Sound Quality One of the standout aspects is the built-in speakers. The sound quality is exceptional, delivering loud and clear audio that eliminates the need for an external sound system. It’s rare to find a TV with speakers this good. The Magic Remote The Magic Remote is functional but frustrating. The cursor behaves inconsistently—if you point the remote away from the screen, it gets stuck on the edge and moves prematurely when you bring it back. For comparison, a Wii Remote re-centers seamlessly, making the LG remote feel clunky and counterintuitive. Customer Service Perhaps the biggest downside is LG’s customer service, which is a nightmare to deal with. They make you jump through hoops to prove the TV has a malfunction before approving warranty service. You’re required to take photos and videos to document the issue, but the pictures often fail to send via text, requiring multiple attempts. Afterward, they may demand a video, but since you can’t record while on a call, they frequently deny warranty claims. This creates a frustrating and time-consuming process that undermines an otherwise excellent product. Despite the TV's strengths, purchasing it comes with the risk of poor support if anything goes wrong. Final Thoughts The LG OLED B4 series offers stunning picture quality, robust sound, and a beautiful design that fits well in most spaces. However, gaming performance can be inconsistent, and the customer service experience leaves much to be desired. While it’s a good TV overall, buyers should weigh the risks of potential support challenges.

    When trying to look for a TV for my bedroom, I was a bit spoiled by the giant OLED I already had in the living room. Looking for the smallest OLED, I came upon the B4. While it has the older A8 processor vs the A9 that is in the higher end C4, the UI is still quick and responsive with only the occasional pause. The speakers are decent and usable, though I did end up getting a soundbar as I found the vocals to sound a bit on the muffled side. The picture itself is as glorious as OLEDs can be - rich vibrant color with amazing contrast, and gets plenty bright in my bedroom. I am not a fan of the remote's gyroscopic pointer feature, but it proves to be only a minor annoyance. Lastly, the fact that all of the HDMI ports are 2.1 is a bonus. The smart TV interface is plenty usable and snappy. The only minor annoyance I have is that when I turn it on, if I immediately go to one of the apps, such as YouTube, sometimes it will not load the content, as if it has to connect to the WiFi first. I have to wait about 5-10 seconds and then the content will load. There is a fast boot option that I haven't tried yet that probably will fix that. At the bargain price of just 599, it was larger AND cheaper than the 42" C4 I was comparing it to. I didn't need anything fancy for gaming - just for watching Netflix, YouTube ,and Apple TV. Slam dunk.

    Got this on sale for $499. An incredible value and perfectly sized for my small living room. The 48" size is available exclusively from Best Buy. I have a 65" C1 LG OLED I bought about 4 years ago (also from Best Buy) and this smaller TV's quality is pretty darn close. The blacks are inky black and the image when playing 120 FPS video games is GREAT. This is an incredible value for the money. The 4 x HDMI 2.1 inputs is a huge plus. People say the speaker in the TV is not great, but I beg to differ. The sound is more than sufficient in my living room and I usually keep the volume at 1/5 max. My only gripe is the remote control (which is the same as my c1) - i've never been the biggest fan of LG remotes, but that is probably just a personal preference.

    Okay, I don't usually write reviews, but I had to share my thoughts on this TV. It's seriously impressive! From the moment I turned it on, I was blown away by the picture quality. The colors are vibrant and realistic, and the clarity is just stunning. Here's what I loved: Picture Quality: Like I said, it's amazing. Sharp, detailed, and the HDR really makes a difference. Whether I'm watching movies, sports, or playing video games, everything looks incredible. Sound: The built-in speakers are surprisingly good. They're not going to replace a dedicated sound system, but they definitely get the job done for everyday viewing. Smart Features: Navigating the menus is a breeze, and the smart features are super responsive. I love having all my streaming apps built-in. Design: The TV itself is sleek and modern. It looks great in my living room. Why not 5 stars? Honestly, it's nitpicking. The only thing that keeps this TV from a perfect score is the remote. It's a little clunky and not as intuitive as I'd like. But seriously, that's it! Overall: This TV is an absolute winner. If you're looking for a fantastic viewing experience without breaking the bank, look no further. Highly recommended!

    Great OLED for the money

    I have had this LG OLED for about a month now and couldn’t be happier. I already had a 55” C series that has been an excellent TV, with the exception of the LG Magic Remote that is very finicky about powering the TV on and off (seems to be just the power button that is the issue) so I have to turn the TV off manually. This 48” IKED is primarily used for gaming with my Xbox Series S console and I am very pleased with how well it performs. Colors are bright, blacks are deep, virtually no lag. The Magic Remote for this TV has worked fine so far and we’ll see how it holds up over time. Because the TV powers on and off with my Xbox (via my controller) I inly use the remote if I watch TV or stream shows so it will probably hold up longer. Be sure the stand you plan to place the TV on is wide enough to accommodate it, the TVs feet are spread pretty far apart. All in all I am loving the new TV.

    Nice TV, Bad remote

    As others have stated the picture is very good. I have an older LG TV that I though the picture was very good until I got this. Some complain about the sound level, I have mine in a fairly good size room and I have never needed the sound level over 40. Some complain about the magic remote, I would be one of those. Maybe if I use it more I might find it OK, but until then I just use the remote from my older LG TV. I know where all the buttons are without looking and can get to some of the TV features that you can not get with the magic one. I would buy this TV again.

    The tv was everything i expected out of an Oled. My issues with it were the size. For me personally it was too big to be a monitor and too small to be a main tv. Other than that, i hated the remote. I strongly suggest getting a better remote for it. The magic mouse is permanently on the screen with their lg remote. I would highly recommend this tv if you like the size, everything you watch on it will be absolutely gorgeous even older shows.

    Watching this thing is a delight. I cannot comment on the smart features as I use Chromecast and Roku but the picture is beautiful. I use a soundbar but the speakers are better than expected. It's in a room which is usually pretty dark except for 2 hours a day when it's insanely bright and it looks good either way. I do not like the magic remote but I have another LG TV so I knew what to expect. Legacy media is not bad, streaming in 1080p is pretty decent and 4K HDR is so good I'm getting spoiled. So far I'm happy with the purchase.

    Love the picture. First OLED tv and i don’t know if ill go back to LED. Hate the remote though. There is a little trackball that you can use to navigate but also HAVE to use as the selection button. Pushing down to select an app often activates the trackball and cursor on the tv, overlaying an annoying pointer on the screeen and dimming it. Awful design.

    Absolutely beautiful picture. Love this tv overall. Remote is annoying with its mouse like feature. It’s extremely responsive but almost too sensitive. Hopefully I can figure out how to disable the mouse feature. For me it actually makes it harder to use.

    Excellent TV so far. I've had for a month or so now and picture quality is great. Very bright even with eye care on. So make sure your sitting area is space out enough from the TV so you don't hurt your eyes. The sound is great as well. I have a sound bar but I dont even use it due to the A.i sound settings it has. My only complaint is the remote. The okay button is a rubber ball that doesn't read all the time at the first click. I definitely had to get use to it.

    The TV picture quality and sound are excellent, but the remote needs to be more user friendly (and needs a better instruction booklet). Most importantly, LG needs to include a PBS app. The web OS can be a bit sluggish sometimes.

    Performing well so far Only annoying issue is the pointer on the remote is automatically connected when turning on the TV. Have to manually deactivate it by pressing an up/down/left or right click. otherwise it will randomly initiate a home screen app.

    I suffer from tremors so using this remote is near impossible. The pointer seems to be motion activated so it is constantly switching to that. Seems they would have thought of people with this issue when designing the remote. I can only use the it when it is sitting on a hard surface. The webOS system is cluttered and doesn't seem user friendly especially when trying to navigate with the remote issues. The picture and sound are great which is the only redeeming things about this TV which I suppose is the main purpose of a TV. I ended up installing my 4K FireStick to make things easier for me. As long as the remote stays the same, I don't see myself purchasing another LG TV.

      Posted .

      Hi, Mike. Thank you for sharing your detailed experience with the LG TV (OLED48B4PUA) model. We’re glad you’re enjoying the exceptional picture and sound quality, but we understand how the Magic Remote and webOS system might be challenging to navigate, especially with tremors. We strive to provide a seamless and user-friendly experience with our products and ensure a smooth experience.

      For an easier experience, you can disable the motion-activated pointer feature by navigating to Settings > All Settings > General > Accessibility > Pointer Options and adjusting or turning off the pointer speed or motion settings. Additionally, LG offers an optional Universal Remote or recommends pairing compatible third-party remotes that may better meet your needs.

      We’re always looking to improve our designs, and your feedback is valuable to us. Please send us a private message on social media @LGUSSupport if you’d like further assistance with settings or exploring alternate remote options. ^Juvy LG

    This was a gift for my Son to replace his current LG LED and he loves it, Buying an extended warranty was a no brainer since the OLED was a great price, I wanted to make sure it lasted him for years. The only thing I will say is that it will take a while to get used to the remote.
