    Reason I like this OLED is if you're not playing anything and its on it'll go into a kind of dim mode. You're not supposed to leave a OLED on static picture for long period of time. The colors are vivid and the blacks are actually black, not a dark grey when you watch movies or play games. I mostly use this to game, it does have a lot of channel features which is always a plus.

    LG B4 48” OLED TV

    The LG B4 48” is excellent if you want a 48-50” TV, you don’t have to pay a huge amount to get a great OLED TV! It has an awesome picture and sound. I cannot speak for the Web OS, I used a Firestick 4K since already knew that system and it worked great. The OLED panel delivers the best TV viewing experience I have ever had. Bright, vivid colors that really pop. I never had any issues with it not being bright enough in a moderately lit to well lit room. It has customizable settings for the different picture modes so you can adjust everything to suit you. If you’re considering a OLED TV don’t hesitate on a LG B4! It was a bargain at $599.99! I highly recommend this TV!!!

    Tv is great for the price. It gives you all the new technology needed for gaming. I would get it if you are looking for a smaller tv with top of the line specs and want an oled screen. You may have picture problems with some content where it may not look good, but when there is a good picture, it looks great. Sounds is also good. The tv enhances sound quality, allowing it to get louder

    I was going to get a different tv than this one but one if the tv guys helped sell me on this tv, honestly im really glad i went with this tv, great picture and color and the tv is rarely laggy or slow in the main interface. The remote for the tv has a pointer/mouse feature which i do not like and wish could be turned off but i havent found a setting for that. One other concern for me would be that there could eventually be screen burn in but time will tell. Great tv in my opinion

    Incredible Picture and Sound – No Soundbar Needed!

    I’m absolutely loving the LG B4 48” OLED! The picture resolution is stunning — colors are vibrant, blacks are truly black, and everything just looks so crisp and lifelike. Whether I’m watching movies, gaming, or streaming sports, the detail and clarity are next-level. The TV automatically adjusts the picture based on what I’m watching, and it makes a noticeable difference — everything looks its best without me having to tinker with settings. I expected to need a soundbar, but the AI Sound Pro feature with the built-in speakers deliver rich, immersive audio that fills the room. Dialogue is clear, bass is punchy, and the overall sound quality blew me away for a TV this slim. This is my first OLED, and I can’t believe I waited this long. Highly recommend the B4 if you’re looking for top-tier visuals and audio experience for a great deal!

    Needed to upgrade the television in my living room to something that had a much better viewing angle. After (far too much) researching different LED panel types, I knew that my best option would always be an OLED. I was concerned that brightness would be an issue because my living room has a lot of natural light - and I couldn’t have been more wrong to be concerned. The screen is wonderfully, and objectively bright, the picture is beautiful, I don’t have any issues with the remote or the OS (but I do use an Apple TV).

    Best Budget 4k 120hz OLED TV you can get for the price $599 black friday. It gets all the bells and whistles for consoles and PC gaming. I actually prefer smaller size TV because you get more PPI. I do not see any green tint like other reviewers talk about. The only reason not to get this TV is Hisense U7N $479 cheaper and bigger. But you don't get OLED and LG brand recognition(good or bad.). I never connect this TV directly to the internet because of the ads and privacy.

    Excellent Display, Can’t Go Wrong.

    Bought this LG OLED TV while it was on sale at Bestbuy. It has excellent picture quality and blows any LCD TV out of the water. The contrast ratio is infinite due to OLED technology, which allows for deep blacks. Other colors are vibrant and inky looking, while motion handling is super smooth. Another plus is that this display supports native 120hz refresh rates and all of the latest standards for 4K hdr high frame rate gaming. In my opinion, you seriously can’t go wrong with getting this TV if you are looking for the best picture quality possible at the lowest price. The fact that it has great software support and is made by LG is icing on the cake. The only downside I can think of is the wide-set stand legs that attach to the TV. They allow for a soundbar to fit neatly underneath. However, it’s very inconvenient if you dont have a table wide enough to support the full length of the tv legs. A center mount stand would be much better in my opinion. Overall, I Highly recommend this TV.

    Price was great and has all the features I could want. This replaced an old Panasonic plasma. I have compared many LED and LCD TV's to the plasma over the years. None of which could compare in terms of picture quality. OLED is the first technology that can best a plasma. And of course energy consumption-wise, the OLED has the plasma beat hands down. Very happy with this purchase. Not only is the picture vibrant and crisp, but it is very bright and the sound far exceeded my expectations. I figured with the TV being so thin that the sound would suffer. I planned to purchase a sound bar to make up for it. However, the sound gets plenty loud and seems fuller than I expected. I "may" still get a sound bar at some point, but I don't feel any urgency to do so. Also, this is my first LG TV. I have always purchased Panasonic for plasma and Samsung or Sony for LED/LCD. I am pleasantly surprised by the quality of the LG. It feels like a good build quality. Doesn't look cheap in any way. And the interface is very smooth and responsive. The apps are much quicker and smoother than those on my Roku. I would purchase this TV again.

    The oled tv for ps5 gaming

    I had a 55in LG oled c1 for years that I used as a gaming tv. I recently gave that tv to a family member and was in search of a new rig. I didn’t want something as large but definitely wanted oled for its low response times and true blacks and hdr for gaming. I am thoroughly impressed by this tv as my main screen for a ps5. Colors render fast, no frame dropping in high stakes moments in pvp. Zero ghosting, and deep inky blacks. Makes space games look unreal. I had a 42in lg c3 and felt like it was too small. The b4 is a year newer, basically has all the tech of the c3, is 6in larger, and is $50-100 cheaper. $800 is an absolute steal for a new oled of this caliber. If you are considering a 32in oled gaming monitor this would be a great alternative for $400 hundred dollars cheaper. I had my last lg oled for about 4 years and it never let me down, and I used it for some long sessions. I’m expecting that I’ll be able to get the same out of the b4. Don’t worry about burn in, just do the pixel cleaning and shut it off when not using it. These panels hold up when you take care of them. If you can get them on sale all the better.

    This TV is amazing. The OLED really makes the colors pop. Using my PS5 pro and being able to use all the tech it offers like 4k, 120hz & VRR really changed the way I game. Movies also look great too especially when enabling the "smooth" option under the trumotion setting, makes the movies appear so much more smoother. Great picture, great price and cheaper than the C4. Can't recommend this TV enough!

    Awesome TV for video games

    I like to use TVs hooked up to my pc because large computer monitors are very expensive. Not only can this TV handle up to 120 frames per second, it's got other features to reduce latency and improve picture while gaming. If you have the GPU to take advantage of 4K, games and videos look amazing. It did take a while to figure out the correct settings for my setup, and I also had to buy a new HDMI cord as my old one couldn't handle that much data and was falling. But, once I did I can game at high fps in 4k and 1440p. Also came in the exact size I wanted, 48 inches. Overall a great TV, solid price especially open box like I got it, and I'm very happy with it.

    Beautiful picture, gorgeous color, brightness is very good. I read that OLED is not as bright as LED but I have no complaints about the brightness, and the picture quality and colors are better than LED backlight tvs that I have seen. This is the budget model and the software is a bit slow but works well overall.

    Had my previous TV for years and figured it was time for an upgrade, and this has been perfect! The picture is bright and beautiful, and I love the option to display art when the TV is not in use. I mostly use it to for my PlayStation and it has truly elevated the experience for me; I hadn’t realized what I was missing until I got this TV. It’s amazing for the price.

    Wow Picture Quality

    After spending a few weeks with the LG 48-inch, I’ve realized that you don't always need to buy the most expensive "flagship" model to get a true premium experience. As someone who uses this for both late-night movies and heavy PS5 gaming, here is my honest take on what it’s actually like to live with. The first thing I noticed—and it never gets old—is the infinite contrast. Coming from a standard LED TV, seeing "true black" for the first time is a game-changer. When you’re watching a movie set in space or a dark thriller, there’s no gray "haze" or light leaking from the corners. t’s surprisingly perfect. It feels much more immersive than a 42-inch on a desk, but it’s not as overwhelming as a 55-inch in a smaller bedroom.

    First oled tv and I must say the picture is phenomenal. The price was unbelievable considering how well the tv performs. The speakers small but loud with dolby atmos does the job. Gaming wise it far outperformed my last tv so yes it is an awesome tv for gamers. If you have a chance to buy one do so performance and rice its hard to beat.

    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.

    I had concerns based on some of the reviews I'd read that indicated brightness might be an issue in brightly lit rooms. But for the price and our dimmer lighting conditions, this model was perfect. It saved us hundreds of dollars over the updated model. The color and resolution are beautiful. The blacks of the OLED give a crisp picture quality. The sound is fine for me but I suppose those with more discriminating tastes may want to invest in a sound bar. Installation was performed by an independent installer.

    An amazing tv at this price (at time of purchase $799). OLED makes a world of difference compared to other tvs. Whites are very bright, blacks are actually black with no need for dimming zones. The picture angles are very good and the color is rich and vibrant. There are times I turn on Youtube and watch 4k/8k video demos just to stare in amazement at how beautiful the picture is. This tv is also amazing for gaming. I think this is where this tv really shines. Great response time and pure eye candy. The only aspect I wouldn't give 5 stars to is the sound. It's ok but nothing amazing. A good soundbar should be next on your to buy list if you don't have one. With a soundbar this tv is simply unmatched at this price. If you can get it at $799 absolutely do it.

    I had a Pioneer Kuro plasma tv that I really loved. The picture was amazing and I was reluctant to upgrade to a newer tv. I’d thought about an OLED tv, but the prices weren’t very attractive. Then I saw this LG model. It was very close to the size of my Kuro, it had 4K resolution and the price… So, I finally decided to upgrade. I’m so glad I did. This tv is phenomenal. The blacks are so deep, the colors are bright and accurate and the design is simple and elegant. Best of all, the price for all this performance is amazing. I couldn’t be happier.
