Another beautiful TV from LG
[This review was collected as part of a promotion.] Bought this TV a month ago and was a bit concerned that it might be a bit too big but it's been absolutely brilliant. The image is incredible. The brightness is a huge improvement over my last LG OLED and it looks gorgeous up on our lounge wall.

Sleek, smart, and genuinely easy to use
[This review was collected as part of a promotion.] I bought this a month ago and so happy I did. First thing that struck me when it arrived was just how slim the panel is, it's almost comically thin for a screen this size, and it sits flush on the wall like a proper piece of art rather than a big black slab. The brightness really does the picture justice too, and the colours pop in a way that makes my old telly look like a museum exhibit. Contrast and resolution are night and day compared to anything I've owned before, watching a dark thriller feels genuinely cinematic now. But honestly, what's surprised me most is how slick webOS is. I'm not the most patient person when it comes to faffing around with menus, but everything just makes sense, finding my streaming apps, switching inputs, adjusting settings mid-film. It's all dead straightforward. Even my partner, who usually calls me over to change the volume input, figured it out on her own. For the picture quality and the polish of the software alone, it's a no-brainer.

Excellent for gaming with the 120 fps.
[This review was collected as part of a promotion.] It’s really good but it’s not the best at focussing on images in the back ground the look like little bits moving around could definitely do with some updates on detail. And also It wouldn’t let me put my model in I don’t know why but it is. Model no. OLED77B4ELA
