About this product
Using innovative 4K OLED technology, the LG OLED B4 gives you incredible picture quality so you can fully enjoy your favourite sport and games like you've never seen them before. OLED is the next step in TV tech, in which every pixel lights itself – meaning deep, inky blacks next to vibrant, dazzling lights! This great picture can also be seen at the widest viewing angle – so anyone in the room can get a great view. Plus with fast refresh rate and OLED Motion technology sport is kept in razor sharp focus.
LG self-lit OLED is the pinnacle of TV technology. All of the screen's pixels are self-lit allowing for perfect contrast, 100% colour accuracy and volume, and the sharpest pixel-perfect details, creating an astonishing viewing experience. Plus the picture looks stunning at any viewing angle.
LG OLED B4 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 TV
[This review was collected as part of a promotion.] Great looking TV. Has a great picture, only downside is trying to get to grips with the magic remote (think Wii remote) as its very sensitive. Ho.e screen is also a bit cluttered.
The Familia

Good price, awesome quality
[This review was collected as part of a promotion.] Tv is awesome, bright enough for my room. Just because is cheaper than other C4, and G 4, doesn't mean is worse.

Well done lg for making a great tv.
Bought the 77in b4 to replace a 3 year old lcd tv and the picture difference is immediately noticeable for the better.the blacks on this tv are incredible compared to an lcd tv and make watching some of my old favorite sifi moves so much more enjoyable.i had changed a few of the settings like turning off the eco mode and motion settings which was a breeze to do. The sound of the tv is ok but we are used to a premium sound system so I feel like it would be unfair for me to judge the standard tv speakers. The only think I don’t like about the tv is the remote and it’s Magic Mouse style curser,we got round this by using our harmony universal remote.the built in apps are all great but we use a fire stick purely out of habit. I’ve connected my Xbox series x and ps5 up to the tv and activated the 120hz game mode which I have found to be lag free with no noticeable screen tearing or black screens during frame rate changes. Well done lg for making one of the best TVs I have had the pleasure of using.
