Q: QuestionWhat is the difference between the 55" C4 and the 55" B4 LG OLED TV's? (besides the price)(1 answer)
A: AnswerHi 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!

This allows for perfect blacks and an enhanced contrast ratio, which are signature features of OLED displays. https://www.lg.com/us/tvs/lg-oled55b4pua-oled-4k-tv#pdp_specs If you need any more details or assistance, feel free to message us privately @LGUSSupport.

Answered by LG Digital Customer Care
- A: AnswerHi Faye! If you notice any disturbances from the speaker while watching TV, you can conduct a sound test on the television to determine if the disturbances originate from it. Not detecting any disturbances during the sound test could be attributed to an unreliable broadcast reception or a faulty external device linked to the TV, such as a set-top box, gaming console, DVD player, Blu-ray player, or computer. Please verify the device's connectivity status. If you encounter disturbances on specific channels, it might be due to an unstable broadcast reception. For further guidance on how to address this issue, please refer to the following link: https://www.lg.com/us/support/help-library/lg-tv-troubleshooting-intermittent-sound-issues-on-an-lg-tv--20153130415089.

Customers are saying
Customers consistently note the exceptional picture quality, particularly the vibrant colors and deep blacks, of the 55" Class B4 Series OLED 4K UHD Smart webOS TV. Many also express satisfaction with the price, especially when purchased on sale. While the TV is generally well-received, some customers find the remote to be overly sensitive and dislike the motion function.

Rated 5 out of 5 stars
Worth it!
Definitely a great TV so far. The picture and sound quality are an incredible improvement from my old tv and it definitely enhances the cinematic experience. It has lived up to my expectations from hours of research before purchase. I know I have yet to unlock the full potential of this tv and am excited to explore the webOS capabilities. I would recommend this tv for Xbox X/S gamers looking to enhance Dolby Vision and Atmos, as well as multiple port options for HDMI 2.1. The HDR from the OLED is definitely worth the extra cost and I am happy to have chosen the B4 model over the B3 in the end.

Strange Optical Digital Audio Out port
I didn't give the B4 an "excellent" rating because of the stupid Optical Digital Audio Out (Toslink) jack on the back of the TV. I unboxed the TV and began setting it up by connecting the optical cord, but it wouldn't stay in! On this TV, the optical jack is just a square black hole! There is no dust cover like there is on other TVs and it there's nothing in the square hole for the optical cord to plug into. So, I boxed it up and had Best Buy pick it up and bring me another B4. It was the same! Anyway, to make this long story a bit shorter, I eventually tried the "optical jack" and it worked, to my surprise. I taped the cord to the "jack" to keep it from falling out, which I think is ridiculous to have to do. They are supposed to click into the jack, but there's nothing in this jack to click into! When the manager at Best Buy called LG, the guy laughed because they've had many calls about this! Yes, I know now that I should have actually checked to see if the "jack" actually worked on my first B4, but...
