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.''
Thank you for using Q and A.
Hello Kevin.
After checking with our supplier, they have advised for LG 48 Inch OLED48B56LA Smart 4K UHD HDR OLED TV.
No, due to the nature of Bluetooth, only one set of headphones can be used at once.
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:
This is 1 year, but longer if you register it with the manufacturer.
Thanks for using Q & A.
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:
Yes, this is possible.
Thanks for using Q & A.
