LG Oled TV - Ideal.
[This review was collected as part of a promotion.] Great choice of TV. Super vibrant colours with good sound. Recommended.

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.

Excellent TV
[This review was collected as part of a promotion.] We got this set as a "new for old" replacement when the insurers decreed our old LG Nano set was BER. We are very impressed with the picture and sound quality as well as the ease of setting up.

Hello Ham,
After checking with our supplier, they have advised for the LG 48 Inch OLED48B56LA Smart 4K UHD HDR OLED TV: ''It would depend on what AI features the customer is referring to, some of the internal features can be disabled but some are always present as the workings of the TV.''

Hello Kevin.
After checking with our supplier, they have advised for LG 48 Inch OLED48B56LA Smart 4K UHD HDR OLED TV.

Thank you for using Q & A.
Hello Rob,
I can advise the following for the LG 48 Inch OLED48B56LA Smart 4K UHD HDR OLED TV:

Hello Kath,
After checking with our supplier, they have advised for the LG 48 Inch OLED48B56LA Smart 4K UHD HDR OLED TV: To record on this TV you would need a external hard drive with it's own power source that is formated to either FAT32 or NTFS.
The alternative option is to get a set top box which would be easier and the better option.
Thank you for using Q&A.
2nd response from Kath above. Im glad to report that on day two of ownership the apps updated successfully and I was able to use them after first going through a simple sign in procedure where codes were sent to me to complete the process for BBCiplayer, ITVX, channels 4,5, utube, Spotify etc. Also multiple LG channels appeared. Im learning that I can also use the tv as a browser and can connect with my mobile using mirroring app where you can use your mobile to enter info on the tv.
I have had this tv 1 day, had issues straight away with internet connection hence you could not add apps you are interested in. Next day the tv connected itself without password info and installed the apps you are interested in. However they all required updating. When I try to do this it repeatedly messages unable to update and non were installed even though the icons were there. Only contact with LG is via email and awaiting response, I can only view freeview channels. User guide is useless.
Hello JJ,
I can advise the following for the LG 48 Inch OLED48B56LA Smart 4K UHD HDR OLED TV:

Thanks for using Q & A.
