Q: What is the difference between the 55" C4 and the 55" B4 LG OLED TV's? (besides the price)
A: Hi there, Vincent. Thank you for reaching out to us with your question. We understand you're comparing the LG OLED55B4PUA and the 55" C4 models, and we'd love to help clarify the differences beyond just the price. Both models feature LG's stunning OLED technology, offering perfect blacks and brilliant colors. However, the main differences lie in the picture processing and performance: Processor: The C4 model comes with a more advanced Alpha 9 AI Processor Gen7 provides smooth, crisp picture and sound with AI Picture Pro and AI Super Upscaling, which provides improved picture and sound processing compared to the Alpha 8 AI Processor found in the B4 model. This results in better upscaling of lower-resolution content and overall picture quality. Brightness: The C4 model has a slightly higher peak brightness, enhancing HDR content, especially in well-lit rooms. Gaming Features: Both models support key gaming features like 120Hz refresh rate, VRR (Variable Refresh Rate), and G-SYNC. However, the C4 may have more advanced gaming options for smoother and more responsive gameplay. For a deeper dive into the specifics, we encourage you to send us a private message on social media @LGUSSupport, and we can explore other details further. 55 inch Class LG OLED B4 4K Smart TV 2024 - https://www.lg.com/us/tvs/lg-oled55b4pua-oled-4k-tv#pdp_specs 55 inch Class LG OLED evo C4 4K Smart TV 2024 - https://www.lg.com/us/tvs/lg-oled55c4pua-oled-4k-tv#pdp_specs We hope this helps!
