The LG B3 OLED typically offers a superior picture quality with deeper blacks and better contrast, which is excellent for watching movies in a dark room. However, it is much more expensive than the Vizio Quantum Pro LCD. In contrast, the Vizio Quantum Pro, while being more affordable, may not match OLED's performance in terms of picture quality, particularly in blacks and contrast, but it's a solid choice if you're on a tighter budget and still want a good quality picture for various content. OLED TVs like the LG B3 can suffer from permanent burn-in if static images are displayed for long periods, making it less ideal if you plan to use it for static content like news tickers or as a PC monitor. The Vizio Quantum Pro doesn't have this issue but isn't as well-suited to very bright rooms due to its lower brightness capabilities compared to high-end OLEDs. If you prioritize gaming, the LG B3's higher refresh rates and support for 4K at 120Hz will provide a smoother experience; however, for casual viewing and a balance between cost and performance, the Vizio can be a more cost-effective solution.
