Overall a great tv
[This review was collected as part of a promotion.] Overall very good, picture quality and sound excellent. Would like to know how to switch on and go straight tv ie bbc but have to go through a menu set up. As an older person this tv seems very complicated but sure will get use to the bits I want.

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!

Hello Muddler.
LG 55 Inch OLED55B56LA Smart 4K UHD HDR OLED TV:
Yes, using a compatible USB drive, you can record via the TV’s built-in recording feature. For best results, use a USB drive of at least 32GB capacity and ensure it’s properly formatted by the TV.
Thank you for using Q & A.
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.

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.

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
