Great TV
We are delighted with our new LG TV. Fantastic picture with vibrant colours, far better than our old TV. Lots more Smart features which are easy to navigate. Our only negative were the feet, too far apart, we changed these for a centre stand.

Just brilliant
[This review was collected as part of a promotion.] Decided to buy this to replace an old 27" LG Ultragear monitor as I'm avid flight simmer. OLED gaming monitors are just ridiculous money, especially something as big as this so thought, TV it is. Pretty plug and play with some minor set up, no need to connect to the interwebs either. Also got my PS5 hooked up with the TV taking full advantage of VRR and 120hz refresh. Just make sure you get decent certified HDMI 2.1 cables, a lot of fakes out there. The TV has auto power saving so dims the screen if not touched for a bit, useful when staring at blue sky for a couple of hours. TV is a breeze to use, and the menu is much snappier than the equivalent Samsung smart TVs. The picture is sharp and in a smaller room, the HDR quality pops. Not really delved into any of the AI upscaling malarkey as I'm mainly using it as a PC monitor. All in all, highly recommended. 👍

Amazing entry-level OLED TV!
[This review was collected as part of a promotion.] A fantastic entry-level TV at an excellent price. The performance is smooth and responsive, with seamless transitions between apps, menus, and the homepage. The OLED panel delivers stunning colours and deep contrast, making it a huge upgrade from an LCD TV. Sharpness and resolution are excellent, allowing high-definition content to look crisp and detailed. Brightness is also impressive, performing well even in well-lit rooms.

Hello Louie,
RE: LG 55 Inch OLED55B56LA Smart 4K UHD HDR OLED TV
The LG OLED55B56LA TV VESA mount specification is 300 x 200mm. This is compatible with the AVF Column Mount Up to 65 Inch TV Stand - this TV stand can be used for TVs with mount sizes ranging from 75 x 75mm to 600 x 400mm.
I hope this helps.
Thank you for using Q & A.
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.
I hope this has answered your question,

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
