Great budget oled tv

Streamed picture is great, off-air not so much.
[This review was collected as part of a promotion.] There is a minor annoyance, that when you switch the set on, it goes to its homepage, rather than going to the last selected source. Also, the picture generated from aerial inputs is disappointing, though using streaming services to show the same content gives a much better picture. I haven't gone through the whole user manual, so there may be a way to tell the AI to improve the off air picture, and upscale it to UHD, but I have not found any such setting. So, off-air programs are fuzzier than streaming ones, or those injected via the HDMI port, making it difficult to read any small text being shown. The sound is good, and will go very loud if you so desire. Very deep sounds positively shake the room!

Great value OLED
[This review was collected as part of a promotion.] My first OLED and really impressed with the picture and sound. I have added an LG soundbar but to be honest the speakers in this tv are the best I've heard. Soundbar is nice however for the Atmos experience. Great TV.

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.

Hello Mighty Shrew.
After checking with our supplier, they have advised for LG 55 Inch OLED55B56LA Smart 4K UHD HDR OLED TV.
The LG B6 OLED offers improved brightness, a more advanced processor, and slightly enhanced HDR performance compared to the B5, while both share OLED picture quality and gaming features.
Thank you for using Q & A.
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.

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
