Customer Ratings & Reviews

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.

I had been researching OLED TV's for the past few months, and ended up purchasing the LG B4 OLED 83" model on Black Friday. Amazing TV!! So when I saw this 48" LG B4 OLED model go on sale for $599 I decided to purchase two, to upgrade a couple of 5 year old Samsung TV's in my bedrooms. The picture quality is superb. Has Dolby Vision, and Dolby Atmos, and 4 HDMI ports - perfect for gaming. The TV sound is adequate, but I usually attach a sound bar for more bass and depth. I was worried about the Operating System after seeing mixed reviews, but the Smart WebOS system is intuitive and easy to navigate, although a little ad-heavy for my liking. All in all, the value can't be beat. No better TV at this price point. Super happy with my recent purchases. Would recommend to anyone looking for a quality TV that won't break the bank

First off, the TV itself looks amazing. Compared to my C3 I really can't tell much difference...the C3 is slightly brighter at max brightness but I never have either that bright. Gaming performance is excellent. It supports 120hz and VRR on all 4 HDMI ports. Pixel response is good, particularly in low latency mode. It also does support G-Sync and works great as a monitor. I've got mine hooked up to my gaming PC and it's been working flawlessly. The only thing that I don't like is it seems to have a bit of coil whine at high brightness levels. LG support told me it's likely coming from the power supply of the unit and it should quiet down over time. To be fair I am very sensitive to that type of high pitch noise so a normal person might not hear it at all. I'll update my review if it ends up quieting down or if I end up having the TV replaced. Overall I'm pretty happy with the B4, especially on sale for the price I paid. If it's on sale again I'd recommend it. If not, I'd wait until it is. At it's normal price you'd be better off going with a C4 for a little bit more.

**Review of the LG B4 48" 4K 120Hz OLED as a Computer Monitor and Gaming Display** The LG B4 48" 4K 120Hz OLED (OLED48B4PUA) is a stellar entry-level OLED TV that doubles as an exceptional computer monitor and gaming display, particularly for my setup. As someone who values vibrant visuals, smooth performance, and immersive gaming, this display has transformed my desk into a powerhouse for both productivity and entertainment. Below, I’ll break down its performance, features, and how it integrates into my gaming and computing environment, drawing on its technical strengths and my personal experience. ### Picture Quality: A Visual Masterpiece The LG B4’s OLED panel delivers the deep blacks, infinite contrast, and vibrant colors that OLED technology is renowned for. With a native 4K resolution (3840x2160), every detail in games, movies, and desktop applications pops with stunning clarity. The WOLED panel ensures perfect black levels, eliminating blooming or haloing around bright objects, which is a game-changer for dark scenes in games like *Elden Ring* or *Cyberpunk 2077*. The B4’s color accuracy is impressive, covering 97.32% of the DCI-P3 color gamut, making it ideal for both gaming and creative tasks like photo editing. However, its peak HDR brightness (655 nits on a 10% window) is slightly lower than the LG C4, which might be noticeable in very bright rooms. For my dimly lit setup, this is a non-issue, as the display still looks phenomenal with HDR content.[](https://www.pcgamer.com/lg-oled48cx-tv-review/)[](https://www.techradar.com/televisions/i-tested-a-cheap-lg-oled-tv-heres-how-it-compares-to-a-more-expensive-oled-tv) The 48-inch size feels like having two ultrawide monitors stacked vertically, offering immense screen real estate for multitasking. Whether I’m gaming, coding, or browsing, the pixel density (around 91 PPI) is sufficient when seated about 32 inches away, though text clarity could be sharper for prolonged reading compared to smaller, high-PPI monitors. The anti-reflective coating helps mitigate glare, but the glossy finish can still reflect in bright environments, so I keep my room lighting controlled.[](https://jahed.dev/2025/03/12/lg-b4-oled-tv-pc-monitor/) ### Gaming Performance: A Dream for Console and PC Gamers For gaming, the LG B4 is a beast. Its four HDMI 2.1 ports support 4K at 120Hz, Variable Refresh Rate (VRR) with Nvidia G-Sync and AMD FreeSync, and Auto Low Latency Mode (ALLM), ensuring buttery-smooth gameplay with minimal tearing or stuttering. The input lag, measured at 9.1ms in Game Optimizer mode with Boost enabled, is exceptionally low for a TV, rivaling dedicated gaming monitors. I’ve tested it with my PS5 and PC (equipped with an Nvidia RTX 3080), and games like *God of War Ragnarök* and *Forza Horizon 5* run flawlessly at 4K 120Hz, with vivid colors and no noticeable motion blur thanks to the OLED’s near-instantaneous 0.03ms response time.[](https://www.techradar.com/televisions/lg-b4-review)[](https://www.tomsguide.com/tvs/lg-b4-oled-review)[](https://www.techradar.com/televisions/i-tested-a-cheap-lg-oled-tv-heres-how-it-compares-to-a-more-expensive-oled-tv) The Game Optimizer dashboard and Game Bar are intuitive, allowing quick adjustments to settings like VRR status, frame rate, and dark area adjustments without pausing gameplay. For PC gaming, the lack of 144Hz support (available on the C4) is a minor drawback, but 120Hz feels plenty smooth for most titles, and console gamers won’t notice the difference since the PS5 and Xbox Series X max out at 120Hz. The B4 also supports cloud gaming platforms like GeForce Now and Amazon Luna, which I’ve used for streaming games with excellent results.[](https://www.techradar.com/televisions/lg-b4-review)[](https://www.rtings.com/tv/reviews/lg/c4-oled)[](https://www.techradar.com/televisions/i-tested-a-cheap-lg-oled-tv-heres-how-it-compares-to-a-more-expensive-oled-tv) ### Integration into My Setup As a computer monitor, the LG B4 has been a game-changer for my desk setup. Mounted on a V-shaped stand (or wall-mounted in some configurations), it fits well on my deep L-shaped desk, though it requires a bit of space management compared to smaller monitors. I use Microsoft PowerToys’ FancyZones to create a 4x4 grid for window management, allowing me to snap multiple applications—like code editors, browsers, and Discord—into precise zones. This setup feels like a true digital workspace, akin to a 120x70cm desk, making multitasking effortless.[](https://www.theverge.com/2022/5/25/23141765/lg-48gq900-oled-tv-gaming-monitor-pc)[](https://jahed.dev/2025/03/12/lg-b4-oled-tv-pc-monitor/) For gaming, I connect my PC via an HDMI 2.1 cable to ensure full 4K 120Hz VRR support, and I’ve enabled Game Optimizer mode to minimize latency. The ability to switch inputs easily (e.g., between my PC and PS5) using the LG Magic Remote is a nice touch, though I mostly stick to PC mode for consistency. The only tweak I made was disabling Auto Brightness Limiter (ABL) using a service remote, as suggested in online forums, to prevent dimming during prolonged static desktop use. This has worked well, and I haven’t noticed any burn-in issues, though I’m mindful of static elements and use screen savers when idle.[](https://jahed.dev/2025/03/12/lg-b4-oled-tv-pc-monitor/)[](https://www.lg.com/hk_en/tv-soundbars/oled/oled48b4pca/)[](https://linustechtips.com/topic/1588791-lg-c4-oled-as-monitor-tips/) Audio is a weak point, with the B4’s 2.0-channel 20W speakers lacking punch for immersive gaming or movies. I’ve paired it with a Dolby Atmos soundbar via HDMI eARC, which elevates the experience significantly. For desk use, I also use a USB-powered DAC with 2.1 speakers connected via the TV’s optical out, which is a cost-effective solution.[](https://www.yahoo.com/tech/lg-b4-oled-review-210027897.html)[](https://jahed.dev/2025/03/12/lg-b4-oled-tv-pc-monitor/) ### Value and Drawbacks Priced at around $799.99 (down from a $1,500 MSRP), the 48-inch B4 is a steal for an OLED, especially compared to the pricier LG C4 ($1,199 for 48 inches). Its value is unmatched in the OLED market, with few competitors like the Sansui 55-inch OLED coming close in price but lacking the B4’s gaming features and brand reliability. The main compromises are its lower brightness compared to the C4, lack of 144Hz for PC gaming, and a reflective screen that requires careful room lighting. The built-in power cord can also be a hassle during setup.[](https://www.ign.com/articles/save-800-off-the-2024-48-lg-b4-4k-oled-smart-tv-doubles-as-a-gaming-monitor)[](https://www.tomsguide.com/tvs/lg-b4-oled-review)[](https://www.yahoo.com/tech/lg-b4-oled-review-210027897.html) ### Conclusion The LG B4 48" 4K 120Hz OLED is a phenomenal choice for my gaming and computing setup. Its OLED panel delivers jaw-dropping visuals, and the 120Hz refresh rate with VRR ensures silky-smooth gaming on both PC and consoles. As a monitor, its massive screen real estate enhances productivity, though it demands a spacious desk and some settings tweaks for optimal use. For the price, it’s hard to beat, offering premium OLED performance without breaking the bank. If you’re looking for an all-in-one display for gaming, work, and media consumption, the B4 is a near-perfect fit—just be ready to invest in a good audio solution and manage its size. **Rating: 5 /5 *Pros*: Stunning OLED visuals, excellent gaming performance (120Hz, VRR, low input lag), great value, versatile for productivity. slightly reflective screen, no 144Hz support, requires desk

Last TV I purchased was a 1080P Vizio in 2011 but I recently picked up a Samsung G6 OLED and experience the colors for the first time. It was such a great experience I decided to move that Vizio in the play room and purchase a new TV for the living room. This thing does not disappoint and also works well with the new consoles at a fraction of the cost of the C4 or C series in general. I'm not a big TV guy but when family comes over they've frequently commented on the colors, especially when football is on because they are vibrant while also not bleeding out which is what makes the OLED tech so interesting.

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!

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.

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 my first time owning a OLED I have to say it's been probably the best tv i ever bought I never seen so much color and perfect blacks mini led tv's come close but it's not this good my gaming and movie experience upgrade with this tv my Xbox series X is perfect for this OLED with Dolby vision gaming the only con is the brightness but everything else outweighs it.

Big gaming monitors are expensive. If you need high refresh rates and large real estate for your FPS games, you may need to spend more money. But for those of us that enjoy RPGs, Sims, and the occasional action game, this was a real no brainer! I've had my eye on LGs OLED televisions for quite a while. I've had this particular one in my cart since it was released. I am very happy I finally purchased. The colors are vibrant and very accurate. The text is always readable. Videos, of course, are gorgeous. I've used TVs before, but this one is the most "monitor like" yet. The size is truly acceptable, and I don't miss my dual 32" curved MSI screens at all. Now, there are some setup issues. We all want the 120hz goodness when playing video games. To do this, I had to enable Dolby Vision. I also loaded an LG OLED profile on my PC, which causes screen timeout fairly quickly if you aren't actively interacting with the screen. There are some acceptable cons. Since I am using this as a monitor, there is a dedicated Hisense TV in the room. The remotes send the same codes and interfere with each other. More care is required when operating either screen with the remote. Dolby Vision can be glitchy with my 4070 card after an extended sleep. It's better to shut down the PC if you aren't going to use it for a couple hours. TBH, I should do this more often as it saves energy. I used a 32" HD monitor mounted vertically for Discord and browser info. If you have a 27" HD, it would probably fit better. I also like the fact that I actually gained usable desk space. Those of you with curved screens know the pain. Best value monitor of 2025. Maybe not the FPS shooter monster, but for all other games, A++++ Do not let the size intimidate you!

I recently purchased the LG 48" Class B4 Series OLED 4K UHD Smart webOS TV (2024) and am highly impressed. The OLED display delivers stunning visuals with vibrant colors and deep blacks, perfect for both movies and gaming. The smart webOS interface is user-friendly, and the Magic Remote makes navigation a breeze. The picture quality is sharp, and the sound is surprisingly rich for a flat-screen TV. Overall, it’s a fantastic addition to my home theater setup, and I’m extremely satisfied with my purchase. Highly recommend!

I’ve tried nearly every TV out there, but LG OLED is in a league of its own. The picture quality is unreal—vibrant colors, perfect blacks, and everything looks so lifelike. The sleek design is a bonus, and it’s super easy to use. If you’re a gamer, it’s smooth and responsive. Once you experience LG OLED, you won’t go back!

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 .

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.

Amazing deal! I bought this tv to mostly game on and its been an amazing experience. Picture is extremely sharp and vivid! Would definitely recommend this tv to anyone gaming looking for a budget friendly OLED! Best tv ive ever owned!

It's a really great picture and offers tons of user friendly features. I really like the built-in Ai systems for image and sound quality. You can have a standard definition TV channel running for a few minutes and then image enhancement makes them look like HD channels, that was pretty wild to me. The brightness also really helps counter any light glare on the screen which is really nice too. These ultimately made understand better why 4kHD TVs are becoming less expensive, the OLED really is a next level, mind blowing experience compared to them. It's night and day, I'm glad I was able to catch the Labor Day discount sale at $750, I've been wanting one for some time but couldn't find what I want for under $1000. The only down side is getting the thing out of the box without breaking the screen. The screen is very very thin, like I'm talking iPad thickness here. (I measured and it's actually 3/8 inch thick!) It's pretty heavy and there's almost no way you can pick it up without leaning it over entirely on one side to get a grip that won't damage the screen. (not a fan of that when it's a $1000 tv)

Beautiful OLED TV. Responsive interface, love the magic remote and glad LG has been sticking with it. Deep colors and brightness is very good (ignore the ppl saying this tv does not have good brightness) Paired with my PS5 pro it's a amazing gaming experience and movies look fantastic. No reason to pay more for the c series (which in some instances the B4 is actually better then the c series for gaming better colors) and def not reason to upgrade to the new g series. I've seen these all in stores and the differences are minimal! No lag lots of options. Vrr, hdr, 120hrtz, 4 2.1 HDMI inputs, 2 USB, and digital optical out! For $550 to $600 this a amazing tv and tbh shines just as good as the newer models! Also the sound is actually really good especially when you turn on ai sound mode! Wow!! Huge difference! Sound bar will always be better but it's not bad at all if you want to save some money right now and not get a soundbar. Must buy and the 48" is perfect for sitting about 5-6ft away!

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!

For the sale price of 600 bucks I don't see any other oled tvs matching this one for picture quality and brightness. 600 for a 48in was definitely easier to swallow than the 1000 for the c4. I'm only planning to stream using apps so it'll do that just fine.

This a really good tv for the price. Great for video games and movies. The blacks are good. The picture is bright and colorful. I highly recommend this tv for your bedroom if you are on a budget.
