Picture quality
I bought this tv on the recommendation of our son who has had the same tv for 3 years tv is excellent
Aldo
Very adaptable TV
[This review was collected as part of a promotion.] Good quality sound, even better picture - but what's really great is the versatility of the picture and audio modes. It allows you to swap through them seamlessly depending on what you're watching at any given time of day (so you can adapt to the light in the room too!). Highly recommend.

The LG B5 is nothing short of spectacular TV
[This review was collected as part of a promotion.] STYLE This TV is one of the best I have ever had. When it comes to style and design, it’s just awesome. I bought a black stand specifically designed to go with it and placed it in the middle of my room—it’s truly a masterpiece. Whenever I come home from work, I look forward to watching crime shows, YouTube, or just flicking through channels looking for something special. Picture Quality What can I say? The picture quality of this TV is out of this world. Whatever you watch—whether it’s regular TV or premium content—it’s crisp and very colorful. I’ve watched the new Jurassic Park movie and Smile 2, and they look amazing. The Filmmaker Mode on this TV is insanely good. I read some reviews online saying it’s not bright enough, but for me personally, it’s more than sufficient. I don’t like overly bright screens anyway—they’re not good for your eyes, especially in the evenings. I always switch off the lights on weekends, grab some popcorn, and watch movies on Prime. It feels like having a movie theater in your own home. Interface and LG webOS The smart TV operating system provides a user-friendly interface for apps, streaming, web browsing (via a built-in browser), and smart features like AI personalization, voice control (with the Magic Remote), and connectivity with other smart devices via the ThinQ app. It’s so easy to use, and I really like the features on the remote. Conclusion If you’re looking for a premium OLED TV and don’t want to break the bank, this is the one for you. Grab it and enjoy—you won’t regret it!

Great hardware, not so great software
[This review was collected as part of a promotion.] To start off with the part most people would care about - TV looks great, picture quality is superb, TV itself looks good, sounds quality is surprisingly great too. The option to pair with a speaker and play simultaneously is a fantastic addition, the delay adjustments that can be made are really good too. Now for the part that might be a bit niche. The amount of ads on the software is frankly gross. I have purchased a very expensive product, a premium product, only to have tons of ads every time I switch the tv and everywhere I look, to the point the software is slow and laggy. Thankfully after much digging I found the menu options to get them off my screen, but they should not be there in the first place. The new remote is awful, the old one had buttons to pause and play and skip forward and back readily there. New one does not, for no conceivable reason, especially with the amount of apps people use. Lastly - the included Copilot that I cannot uninstall. Get that trash off my machine, I don't want it, I don't need it, it only takes space I could use for other things. Give me an option to deduct the license fee and get it off the TV, honestly. So much stuff added and still no option to make the TV just boot up YouTube or any other app instead of starting off on the tv channels/menu. Surely that kind of software update isn't impossible, I know so many people have asked for this option for years on official forums. All in all, the hardware of the TV is great, but if I knew the amount of bad software I'd get on it and not able to remove, I would have probably kept my old TV.

Hello Jack,
No, the LG 55 Inch OLED55B56LA Smart TV does not support Wi-Fi 6 (802.11 ax). Wi-Fi 6 is an industry certification for products that support the wireless standard 802.11ax, which is designed for high-efficiency wireless networking. However, the LG 55 Inch OLED55B56LA Smart TV does not have the necessary hardware to support this standard.
I hope this helps.
Thank you for using Q & A.
Hello Jack,
LG 55 Inch OLED55B56LA Smart 4K UHD HDR OLED TV:
The LG 55 Inch OLED55B56LA Smart 4K UHD HDR OLED TV does not support Wi-Fi 6 (802.11 ax). This model is part of LG's B-series, which is known for its affordability but lacks advanced connectivity features like Wi-Fi 6.
I hope this has answered your question,
Thank you for using Argos Q&A

Hi Ginger sian,
Regarding the LG 55 Inch OLED55B56LA Smart 4K UHD HDR OLED TV, I can confirm that it doesn't need and external ariel if you are only using it for streaming services. To watch live Freeview channels, you will need an aerial, however if you're mainly watching content through streaming services, no aerial is needed.
Thank you for using QandA
