Nice tv
[This review was collected as part of a promotion.] Good TV a nice upgrade from my last one was contemplating spending more and getting the c5 but I got a good deal on this one and don't regret my decision. Great for playing Xbox and watching cinematic movies

Great improvement
[This review was collected as part of a promotion.] Overall it's a great improvement on my old (not even 4k) TV. The sound has taken some getting used to, seems oddly balanced very quite then exceptionally loud. The image is amazing and the overall look is sleek and modern

Excellent picture, subtitles difficult to turn on.
[This review was collected as part of a promotion.] Excellent picture, but over complex thanks to promotions etc. Also getting subtitles is lengthy involving many menus to go through. Do the designers not consult people who are hard of hearing? We can hear many programmes and don't want the subtitles on when listening to the news (for example). The subtitles are so far behind what is being said they are distracting. But films and drama are often hard to hear and we want the subtitles on. Why can't we have a single button to toggle this like we had on our old Panasonic TV? There are about 4 or 5 menu selections to go through to get to the page where you turn them on - and then they are at the bottom of the list so you have to scroll down. This is poor design. Docked two stars because of this and the complexity of the menus. Things are a bit better now I've turned off the promotions and suggested programmes.

New OLED LG TV
[This review was collected as part of a promotion.] Early days, to give a full review as only had it running for 2 days. First impression, not user friendly to use, keeps wanting to switch to LG channel's and not stay with my freestat box. Still getting use to the main screen and hope to remove many of the pre installed apps which I will never use to stream line my viewing. Colour's and sound are excellent.

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.

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.

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.

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
