    Beautiful colors

    This TV is absolutely gorgeous. Coming from a plasma with great inky blacks I did not want to upgrade at all but I am glad to have gone OLED. And don't let the "entry level" tag placed on this tv fool you, it's OLED through and through. Beautiful colors and deep pure blacks. And with the right settings, the picture is natural and sharp. I am beyond happy. The speakers are way better than I would have ever thought. My only negative is that OS is sluggish. I like it better than some others but it's a little slow which is where the price probably comes in. But it's not bad enough for me to pay the difference for the next model up. Overall I highly recommend this TV for exceptional movie watching and gaming.

    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.

    Stunning Picture – A Total Game Changer for Movies

    I am absolutely blown away by the infinite contrast and vibrant colors on this LG OLED. Coming from a standard LED TV, the difference is night and day; the "perfect blacks" make movies feel like a true cinema experience. Even in a brightly lit room, the picture remains crisp and clear. If you’re a movie buff looking for the best visual experience possible, this is worth every penny.

    My first OLED and I love it!

    The picture is amazing! Reminds me of my old plasma tv. Picture is nice an bright for our livingroom, no issues in the daytime or nighttime. No major concerns with reflections from the kitchen. Wife loves it, so that's a definite plus!

    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.
