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!

(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
