Review: Perfect picture! - I’m brand new to the OLED experience. All of my previous tvs have been the LED variety. This tv just continues to wow my senses! Every show no matter the medium looks fantastic! I’ve watched only black and white movies, color movies made in the 50s and 60s, modern 4k movies, and just standard 1080p movies and everything just looks gorgeous! You can see the details very clear. Blacks are BLACK and not just a muddied gray. There’s ZERO blooming. Watching Outlander is a pure treat. Yellowstone is amazing! I am gaming on this with a pc and my EVGA 3080 has no issues playing games like the new Marvel Guardians of the Galaxy on ultra everything. The colors of the games look superb. My wife can back all of this up. She was a huge skeptic and didn’t understand why i wanted us to upgrade to this tv. She didn’t understand that is until we watched our first movie on it and she was completely blown away. I don’t think we can ever leave the OLED experience now. I looked at other tvs before buying this product. I looked at Samsung’s QLED tvs and LGs QNED tvs and none of them compare to this. I don’t know what’s the difference in picture quality between the LG C2 line and the B2 lines other than price but I’m telling you for the price i paid here at desertcart I love my B2. Now I’ve only used the tv for a couple of weeks as this was a Christmas purchase. So far I love everything about the tv and what it can do. Even the sound from the tv is good. I’ll update this if anything changes but for now I’m super happy with this purchase. Update: it’s Super Bowl weekend and this TV is on sale. Grab it. I still love my LG B2 and nothing I said before this update has changed. It’s going to be great watching the Eagles and Chiefs go at it for the big prize.
Review: Amazing TV!! Perfect color reproduction, best OLED for gaming. - What can I say, this TV wins in every category. ONLY negative might be the LG operating system, I find it a bit clunky at times. One thing being that if you shutdown the TV from playing a game on say PS5 or Switch, when you turn on the TV again it will automatically try to open up whatever input the gaming system was on and not go to the home screen. This makes you have to push the home button every single time, which gets a bit annoying. Not a huge deal, just something I needed to share. If there is a way to turn that off, I have not figured it out yet, so not worth taking a star away. Other than that, this TV is amazing! Outstanding picture quality, 120hz refresh rate for gaming with auto low latency mode for competitive gaming. Also, because it is an OLED, the viewing angles are excellent, absolutely not trouble from any angle, even at close to 180 degrees being viewed from the side. The built in speakers are also not to shabby. If your in the market for your new or first OLED, this one deserves your attention!

*by S***W on December 28, 2025*

Loving the picture quality....have had some issues with it LG updating it's software and then causing issues between switching from apple tv to ps5 and so and so forth with lag and sync stuff. Stopped allowing the tv to update.
