    Never regret true OLED

    Outstanding picture quality and incredible contrast. Lives up to the rtings review. Downside: LG’s webOS interface is confusing compared to Roku. Thankfully I never have to see it - I just use the AppleTV interface. Only problem I’ve seen is a few seconds of blackness when switching to Dolby Vision (automatically), which is insanely vibrant and bright.

    Bought the 48” B4 to use as a Monitor for PC and there is NO TV or Monitor that competes with this TV for how much I paid ($599). Definitely recommend. Coming from a QLED TV the only complaint I have is that it’s not as bright but that’s to be expected with OLED. Everything else is perfect.

    Replaced my old bedroom 49" LG LED with a 48" LG B4 OLED and WOW what a difference in the quality of the picture. I have an 65" LG 8K (all LGs were purchased from BestBuy) in the living room and the new OLED is a very close 2nd in terms of viewing pleasure for HD and 4K video.

    If you're looking for a budget OLED TV look no further than the LG B4. The blacks look good has tons of options for setting up the perfect picture to make watching or playing games look great.

    Extremely poor quality and experience

    If I could give this product zero stars I would because this LG TV has been a big disappointment from day one. Let me start out by saying that the picture quality this TV possesses is excellent but that is the only thing that was good about this product. Best Buys service and price is fine and I don't have any problems with Best Buy because they did what they could. To start, navigating all of the AI and all that is not easy and it was not a good experience. There should be a setting to turn all of that off and be done with it. Thats probably my fault because I'm an old school guy that is simply not accepting of all the new AI options and whatever. The issues with this TV started maybe a month after I bought it in August of 2024, which was only 14 months ago from when this review was written. The TV every 4 or 5 days wanted to run the clean pixels process which was a pain in the a.. to actually accomplish. A message would come up with instructions to click OK and it would perform the process. It didn't work because the next time I turned the set on it wanted to clean pixels again, and again, and again. I tried cleaning the pixels manually and on and on until eventually it decided to complete the process and the message went away. That is until it wanted to do the pixel cleaning again 4 or 5 days later and I had to go through the days long process again to get the message to disappear. There is no option to turn pixel cleaning off. Jump ahead to this week, November of 2025, 14 months almost to the day after I bought this TV. It stopped working and is now DOA, that is dead on arrival and it will no longer even power on and turn on. My next action will be to bring it to the dump and get rid of the thing as hazardous waste. I unfortunately did not get the extended warranty which would have covered the product and the Geek Squad would have come in to do a house call and see if it could be fixed. That's my second mistake with this TV with the first mistake being my purchasing it in the first place because I should have bought a new SONY. My old SONY Bravia that I was replacing was 17 years old and had no problems other than a few dead pixels, which is why I was replacing it. I called LG because that was my only recourse. I figured that it might be something that I was doing and I wanted to talk to a service person. The service person was nice and I went through her checks. Yes, the little red light on front was on and when the TV was turned on with the remote the red light blinked but no picture came on, it was dead. To end this sad review, the LG service person said she would elevate this issue to a higher service level and that she would call me back at 1 pm the next day and tell me what they said. LG never bothered to call me back and I waited all day. With that said. my opinion of LG is that they sell junk so make your purchase with that in mind. I bought this OLED TV 14 months ago and it only lasted 2 months past the warranty expiration date and it died and now I need to go out and buy a new set, which will be a SONY this time and I will get the extended service. One last thing, do not let let the AI on the TV log in to the LG web site to register the TV because that does not work either. My registration that I did from the tv was not showing up on my LG account. I had to convert the LG account from the TV to the Internet so I essentially never even registered it! But I was still getting ads from LG every single day because it appeared to have been registered when it wasn't. This LG experience was horrible and it turned out to be a horrible product so buyer beware. If it happened to me it could happen to you because LG seems to be very poor quality in my opinion. Their customer service are liars as well because they never bothered to call me back and tell me it wasn't registered and that the warranty had run out, which I already knew. Best Buy however is just fine, poor product quality isn't their fault and they will stand buy it if you have the Geek Squad coverage. So my last suggestion is to buy their 3 year Geek Squad warranty or whatever, especially if you chose to go the LG route. Good luck. My next TV will be a SONY because it lasted 17 years and will probably be bought at Best Buy because there really isn't any other place to purchase TVs these days.

      Hi, Howiee. Thank you for sharing your detailed experience with the LG TV (OLED48B4PUA) model. We appreciate the time you took to explain what happened and want to provide some guidance.

      For this model, the Pixel Cleaning process is an automatic maintenance feature designed to preserve picture quality. While it cannot be disabled, it should normally run in the background without repeated interruptions. If the TV continues to request pixel cleaning excessively, one step you can try is performing a full power reset: unplug the TV for at least 5 minutes, then plug it back in and attempt to power on again. This can sometimes clear persistent system prompts.

      Since your unit is no longer powering on, and the red standby light blinks without displaying a picture, this indicates a hardware issue that requires service. For more information, visit https://www.lg.com/us/support/help-library/lg-tv-power-my-tv-wont-turn-on--20154763472499. Please send us an email at [email protected] with your product details so we can assist further in exploring service options. ^Juvy LG

    Decent OLED

    It was a decent OLED for a great price but ends up being too small to really appreciate the technology. It was also almost TOO bright for a bedroom in the dark. Lastly, I did not love the magic remote, it made too much noise with the button clicks. I ended up returning it and plan on getting at least a 65" OLED in the future.

    Picture is wonderful. Sound his fine. The operating system is quirky with problems two apps: Sling and Tube. Both are being worked on with LG technical help. Shouldn't be with a new TV at this level.

    Tv is great, everything is awesome except for 2 annoyances. Those are the annoying and unsatisfying remote, and bloaty seeming TV UI. The remote is not really "clean" or simplistic it is doing way too much, and the TV default UI almost seems like its stuffed with bloatware and is a little laggy. Overall if the quality of life stuff was more simple it would be 5 stars or beyond.

    Needed a 48” TV for bedroom. Any larger wouldn’t fit. We’re spoiled- after purchasing a large OLED TV for the living room, nothing but OLED is acceptable for us! Well this LG has beautiful, clear picture, and the brightness level isn’t an issue in the bedroom. Very pleased with the purchase, especially since it was on sale.

    No burn-in after 781 hours of use and great color range. The only issue I have is that the glossiness of the screen can make it a bit hard to see at certain times of the day.

    I bought this for my husband as an early Christmas present. Our son is on the spectrum and damaged our old one, but it was time for an upgrade! My husband is pleasantly surprised with the quality of the oled picture. Best Buy had a great sale and my transaction was flawless. Happy family!

    Excellent as a monitor! Almost great as a TV. Upscaling sucks. I have a C2 tv for movies and I can see the difference. If the movie itself provides high resolution, there is no difference. So pay Netflix for that 4K UHD definition. Upscaling for PC does not work on any tv anyway, so if you buy it as a monitor it's the best.

    Not Too Bad, But...

    So far it's a very nice OLED TV with a few issues. I have had to navigate a few glitches along the way which were not present with the SONY Master Series TV it replaced. First, one time the TV just shut itself off while the Netflix wallpaper was rotating after I had binged a series. Changing a few setting may have solved the issue. Second, not loving some of the blown out whites as I will call it and being a novice have had to play around with the settings to get it to where I don't mind the picture. Third, the audio will go out of sync at times when I pause the Spectrum DVR and restart -- again never an issue with my SONY which was replaced thanks to too many hours of Fan Duel TV (horse racing) with their huge chyron. Finally, at times have felt my Yamaha (non eARC) sound bar was having issues so turned that off and things seemed to have gotten better. All in all not bad for a $600 OLED, but the glitches along the way have been irritating.
