Amazing picture! LG Magic Remote is included. Easy TV setup with the LG ThinQ mobile app. I do find the smart TV interface of the TV cumbersome to navigate so I chose to add an Apple TV (which the LG Magic Remote can control). For sound I'm using a Sonos Beam 2. The Apple TV and Sonos soundbar work seamlessly with the TV. The TV weighs less than 26 pounds! I like this set so much I'm adding the 83" version to my living room.

I purchased this to get the most out of PS5 Pro. The quality of the picture and all the settings for gaming are crazy. I couldn't be happier with this purchase. I caught this on sale for $599, and that's a steal. If you're on the fence, I suggest going for it.

The LG B4 is an awesome tv if you are looking for an introduction into OLED. Very affordable and after 4 months, the tv is still goin strong. The 4k 120hz is gorgeous, especially during gaming sessions. I highly recommend this tv for someone who needs a tv for the bedroom and can even be used as a monitor for a large desk. Highly recommend

I am very happy with this LG OLED 48” TV. It replaces a 50 “ plasma TV. I was worried that I would miss the larger screen, but I don’t. The picture clarity is great, as is the sound; I did purchase a JBL 5.0 soundbar. The Best Buy installation was professional. Though they set everything up for me, I was able to easily able to fine tune the picture using LG videos. I am happy with this TV.

The picture is amazing… most of the time. Even after turning off all of the motion smoothing, noise reduction and “AI” features, 1080p and lower content still looks a little shaky. I also had trouble with screen flickering at first. I think it was a power issue, because it stopped when I started turning off the power strip when not in use.
Needless to say, movies on 4k Blu-ray look amazing, which outweighs my minor quibbles (like the unavailability of certain apps - mainly the Criterion Channel).

I recently purchased the LG 48" Class B4 Series OLED 4K UHD Smart webOS TV (2024) and am highly impressed. The OLED display delivers stunning visuals with vibrant colors and deep blacks, perfect for both movies and gaming. The smart webOS interface is user-friendly, and the Magic Remote makes navigation a breeze. The picture quality is sharp, and the sound is surprisingly rich for a flat-screen TV. Overall, it’s a fantastic addition to my home theater setup, and I’m extremely satisfied with my purchase. Highly recommend!

Once you go OLED you don’t go back. This is my second LG OLED. LG ftw! For this pricey you can’t go wrong. Great starter OELD, but be warned you will need to up grade all your tvs to OLED.

I'm so happy with this TV.
I collect movies, so this was mainly to watch blurays.
What I was interested in was Filmmaker Mode, I would prefer to see a movie as unadulterated by TV presets or custom settings; like if you go from one theater to the next it will look the same. I actually read bad reviews on Filmmaker Mode, but I love it.
The speakers are so good imo. I'm using the AI sound preset (forget the exact name) and it sounds fantastic.
The smart hub is cool, and I like how easy it is customize.
The Magic Remote is pretty great, I like how you can do voice commands. The scroll is cool.
The LG ThinQ app is handy and cool. I also like that you can bring hour phone files up on the TV.
It's such a beautiful looking TV overall, very thin. For me, it is perfect.

The next-gen of TVs

It's a really great picture and offers tons of user friendly features. I really like the built-in Ai systems for image and sound quality. You can have a standard definition TV channel running for a few minutes and then image enhancement makes them look like HD channels, that was pretty wild to me. The brightness also really helps counter any light glare on the screen which is really nice too. These ultimately made understand better why 4kHD TVs are becoming less expensive, the OLED really is a next level, mind blowing experience compared to them. It's night and day, I'm glad I was able to catch the Labor Day discount sale at $750, I've been wanting one for some time but couldn't find what I want for under $1000.
The only down side is getting the thing out of the box without breaking the screen. The screen is very very thin, like I'm talking iPad thickness here. (I measured and it's actually 3/8 inch thick!) It's pretty heavy and there's almost no way you can pick it up without leaning it over entirely on one side to get a grip that won't damage the screen. (not a fan of that when it's a $1000 tv)

I bought this 48” LG OLED TV on sale for $600 to pair with my new PS5 Pro. It’s a worthy OLED TV that has exceeded my expectations. The clarity and smoothness of the image quality is some of the best I’ve seen yet, especially for the price. You get more than what you pay for.

Amazing picture. OLED is the best. Not much difference in picture quality other than brightness from the more expensive LG C4. Only complaint is there is some judder in fast moving scenes and sports even though TV is 120 Hertz.
