About this product
Transform your home entertainment with this LG 48 Inch Smart TV that brings cinema-quality 4K OLED visuals and intelligent gaming features to your living room. Self-lit OLED technology means every single pixel lights itself independently, delivering deep, inky blacks alongside dazzling bright colours with perfect contrast and 100% colour accuracy. The clever Alpha8 Gen2 AI 4K processor works away in the background, upscaling whatever you're watching to stunning 4K quality whilst enhancing audio for a more immersive experience.
Dolby Vision and Filmmaker Mode deliver films as the director intended, while the 120Hz refresh rate and OLED Motion keep fast sports and action scenes sharp. Gamers will appreciate the 0.1ms response time, 4K at 120Hz, VRR, ALLM, G-Sync, and FreeSync support. LG's webOS smart platform offers instant access to Netflix, Disney, Prime Video, BBC iPlayer, Now TV, and YouTube, all controlled via the AI Magic Remote compatible with Alexa and Google Assistant. With 4 HDMI ports, 2 USB ports, built-in Wi-Fi, Bluetooth and Dolby Atmos with 20W output, connectivity and audio match the stunning picture.
LG OLED B5 features the new 8 AI Processor, the brain of the TV. This intelligent processor intuitively ensures optimised picture and sound quality and delivers image enhancement through AI Super Upscaling. It will also upscale audio for a more cinematic experience.

Great budget oled tv
[This review was collected as part of a promotion.] Tv looks fantastic and the sound is surprising solid only downside is that it could be a little brighter so not great for direct sunlight

Superb picture, awful external sound interfaces
This LG OLED TV has a great picture but is let down by seriously poor audio interfaces and setup, a very sub-par WebOS system and a very annoying AI feature on the remote control. If you just want a punchy, contrasty picture with excellent colour rendition then this is pretty much perfect for the money. You can easily set it up such that it produces realistic colours rather than the overdone ones that can be presets on some TVs. Brightness is easily good enough for indoors. However, that has to be weighed up against the fact that the audio interface/connection/setup is the worst I have ever seen on any electronic device, period. Bear in mind we're using it with an LG soundbar, so it should be seamless. First off, the optical output is so tight you risk breaking the circuit board trying to insert a cable. I had to shave off the flanges on the cable to get it to fit. (It fits the same connector on the LG soundbar perfectly). It's best when using LG TV Bluetooth pairing to connect to same brand devices as you get more than 2 channels. Sometimes it works, sometimes it just fails and uses TV speakers. If you turn the soundbar on after the TV it never connects. If you need to manually connect you have to go through a mess of clicks and embedded menus to get to the saved BT device and then if it connects it still doesn't quit! You literally have to back out of everything again. A totally moronic design. It frequently fails even then, requiring a full TV reboot. Add to that the remote has a useless AI mode the button which is exactly where you rest your finger so it triggers all the time. Oh, and it frequently converts the TV to audio description. The whole interface and software is a god-awful mess. Still, what a picture!

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!

Good for the money - but slower than my prev LG
Good TV for the price, the pointer remote is really useful. I do find it slower than my previous TV when changing channels an apps.

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.

Hello there
LG 48 Inch OLED48B56LA Smart 4K UHD HDR OLED TV
Yes, the legs/stand should fit on your TV cabinet if your cabinet is at least 93.3 cm wide, even if the screen itself overhangs past the edges a bit.
Thanks for using Q&A
Hello Aaron,
I can advise the following for the LG 48 Inch OLED48B56LA Smart 4K UHD HDR OLED TV:
This is 120Hz.
Thanks for using Q & A.
Hey Graham,

Thanks for using Q&A.
Hello Mark,
The supplier has advised the following for the LG 48 Inch OLED48B56LA Smart 4K UHD HDR OLED TV:
“Yes our TV's do have the Freely App”
Thanks for using Q & A.
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.
