Reviews
LG 77" B5 Smart 4K OLED AI TV (2025) with webOS 25 is rated 4.7 out of 5 by 23.
Rated 5 out of 5 by from Amazing! [This review was collected as part of a promotion.] My husband and I have been looking for the perfect TV for our living room, and we stumbled across this one. What stood out to me was the size of the TV; it filled our wall without being too large. I also really loved how slim the actual TV is, as it doesn’t take up much space on the wall. The sound quality is great, and you barely need to turn the TV up to hear it play loudly. The picture quality is also amazing, and we have been able to enjoy all of our favorite shows. It was super easy to set up and took less than 10 minutes. Review submitted as part of a program that provides a purchase discount.

Rated 5 out of 5 by from Amazing color and picture quality! [This review was collected as part of a promotion.] The LG B5 OLED TV is easy to set up and has definitely exceeded all my expectations when it comes to picture quality! The colors are super vibrant and it is amazing how much of a difference you can tell between a non-OLED TV and the B5. It is ideal for daily TV watching, movie nights, and gaming. Besides the incredible picture quality, it also runs very smooth and switches between apps quick and seamlessly. All in all, the LG B5 OLED TV is great and I can highly recommend it if you are looking for a new TV. Review submitted as part of a program that provides a purchase discount.

Rated 5 out of 5 by from An amazing TV with stunning picture quality and gr [This review was collected as part of a promotion.] I actually bought this LG 83” OLED B5 4K Smart TV just a few days ago for my parents , so it’s funny that I got the coupon today! Even without the discount, I have no regrets the picture quality is absolutely incredible, the colors are vibrant, and the blacks are deep and true. The sound is surprisingly rich for a flat screen, and the smart features are easy to navigate. The remote is sleek and responsive, and connecting my devices was simple. It’s been an awesome addition to movie nights at home. Thank you Influenster for the opportunity

Rated 5 out of 5 by from A Worthy Upgrade [This review was collected as part of a promotion.] Just upgraded to the LG B5 77” OLED from my 2017 LG C7 65” and I‘ve been blown away by the quality. I’ve been using it for watching sports, streaming shows and movies, and gaming. It’s been amazing across the board for all of those. The picture is super sharp, colors look incredible, and the brightness has worked great in my bright living room. Watching sports makes me feel right in the action, and games run incredible smooth. The smart TV features are easy to use, which makes flipping between apps super quick and seamless. The AI features have been great in recommending the best picture setting for whatever app I may be using. Attached to this are pictures of my setup!

Rated 5 out of 5 by from Stunning picture and sound [This review was collected as part of a promotion.] I upgraded from an 82" 2019 QLED to the LG OLED83B5PUA and have been blown away by the difference in picture quality. Blacks are obviously better, but everything is crisper, with a 3D quality that was missing from my old TV. This is in a living room that doubles as a casual daytime spot and a theater room at night. With Dolby Vision and Dolby Atmos playing 4K content, movies come alive. I’ve even found myself putting on the kids’ animated movies just because they look so stunning on this TV. I compared the B, C, and G series side by side in-store. While I could see some subtle differences, I knew I’d never watch them like that at home, and I’m very happy with my purchase.

Rated 5 out of 5 by from Sleek, fast and excellent picture quality [This review was collected as part of a promotion.] The LG 77" B5 OLED is legit. The picture is super clear, the colors pop, and it just makes what you're watching look so good. Movies, shows, games, whatever, it all looks super smooth and sharp. Gaming (which my husband tried right away lol) especially feels really fast and responsive with no lag, and it supports 4K at 120Hz which is awesome. The built-in smart features are easy to use, and the remote has voice control which is actually really handy. The picture quality is so good, you just get pulled right into whatever you’re watching. The colors are super vibrant, the blacks are deep, and everything looks insanely sharp. For the size and everything you’re getting, it's more than worth it.

Rated 5 out of 5 by from Picture, sound, experience- Exceptional! [This review was collected as part of a promotion.] I have always wanted an OLED TV. I saw this one and decided it was time. I have to say, the colors are outstanding. I’m a big gamer and my games I play look exactly like I’d expect from a TV of this caliber! As for the UI I was pleasantly surprised, LG webOS is super easy to use and there are a ton of cool AI features integrated into this TV. The remote is sleek and connecting all our devices was smooth and easy. Also super happy they have an app that works in case the remote ends up under the couch lol. My kids comment constantly that it looks like we are in a movie theater so I’d say it was a good choice! Overall a great purchase and it’s exceeded my expectations. If you are thinking about the switch to OLED, I’d say get after it!! Review submitted as part of a program that provides a purchase discount.

Rated 5 out of 5 by from Good [This review was collected as part of a promotion.] Absolutely stunning picture quality. The blacks are deep, colors are rich, and motion is incredibly smooth. At 83 inches, it's like having a cinema at home. Great for movies, gaming, and sports. The smart TV interface is easy to use, and Dolby Vision + Atmos really adds to the experience. Expensive—but worth every dollar if you're serious about home entertainment.
