  • Q: What is the difference between the B4 model and the C4 model (OLED48C4PUA)? (1 answers)

    A: Hi there. Thank you for your question! We understand that you're curious about the differences between the OLED48B4PUA and OLED48C4PUA models. While both offer stunning 4K OLED displays and 120Hz refresh rates, here are a few key differences: Processor: The OLED48B4PUA features the α8 AI Processor, while the OLED48C4PUA is equipped with the more advanced α9 AI Processor Gen7, which provides better image processing and AI upscaling for enhanced picture quality. Gaming Features: The C4 model supports VRR (Variable Refresh Rate) up to 144Hz, AI Upscaling, and Game Optimizer, making it a better choice for gamers. The B4 model is still great for gaming but maxes out at 120Hz for VRR. AI Features: The C4 model also includes additional AI features like AI Picture Pro, AI Sound Pro, and AI Concierge, which are not present in the B4 model. These enhance sound, picture, and overall user experience. Audio: The C4 model has a more advanced 2.2 channel speaker system with Dolby Atmos and AI Sound Pro for a richer sound experience. The B4 model offers a standard 2.0 channel system. Both models are excellent choices, but if you're looking for a more premium experience with advanced processing, enhanced gaming, and AI features, the C4 model might be the way to go!

  • Q: Will this have burn in issues because its OLED? (1 answers)

    A: Hello there! While OLED technology, including the LG OLED48B4PUA, can be prone to burn-in issues due to its nature of using organic compounds, LG has incorporated several features to help mitigate this risk. These include pixel shift, screen savers, and automatic brightness adjustments. To further reduce the risk of burn-in, it's a good idea to avoid displaying static images for extended periods and use the TV's built-in settings to manage screen usage. If you have any concerns or need more details on managing burn-in, please send us a private message on Social Media @LGUSSupport, and our team will be happy to assist you. We appreciate your attention to maintaining your TV's performance. —Renzo

    Highly Recommend This Television

    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.

    Perfect bedroom tv!

    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.

    The next-gen of TVs

    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)
