        Recommend

        This LG OLED B5 AI 77” is absolutely worth it. The picture quality is stunning — deep blacks, vibrant colors, and excellent brightness for both movies and sports. Dolby Vision and HDR really make a huge difference. The motion handling is smooth, perfect for fast-paced action or gaming. The AI processor does a great job optimizing the image and upscaling lower-resolution content. Sound is surprisingly good for a slim TV, but pairing it with a soundbar takes the experience to another level. The design is sleek and modern, and it looks beautiful mounted on the wall. WebOS is very fast and user-friendly, with all the apps I use (Netflix, Prime, Apple TV+, YouTube) running smoothly. Overall, an excellent purchase — premium quality at a great price. Highly recommend it if you’re looking for a large screen OLED with amazing performance.

        Great Picture

        We bought this to upgrade from a seven year old LG 65” 4K LED tv. The difference is amazing. This 77 inch 4K OLED LG has a noticeably better picture, blacks are blacker, and colors are more vivid. The new style magic remote is definitely an upgrade. The TV was delivered and installed by Best Buy. They did a wonderful job on the installation as well as explaining the features. They installed an in wall wire kit and did a professional job. I bought this during the Black Friday sales and saved almost 50% off the list price. I’ve used Best Buy for years and plan to continue using them in the future.

        Exceeds Expectations

        I’m extremely impressed with the 77" B5. The picture quality is absolutely stunning, and the OLED really shines with vibrant colors, deep blacks, and excellent brightness. When I’m watching movies or sports, the images are incredibly immersive and crisp. This TV consistently delivers an impressive viewing experience. Overall, I couldn’t be happier with the image quality, and it easily exceeds my expectations.
