We wish we'd bought it sooner
[This review was collected as part of a promotion.] The LG OLED48C55LA 48-inch TV is an outstanding upgrade from our old Panasonic LCD 32 inch TV. The LG delivers superb picture quality for our viewing distance of about 2.5m. It produces black blacks – not something we were used to owning and LCD TV, excellent contrast and realistic colours that are remarkably sharp with excellent upscaling for HD content. The screen is almost mirror-like and can suffer from reflections and benefits from blackout curtains when watching movies. The speakers aren’t great (as expected for such a flat TV) but fine for watching the news and documentaries etc but the experience is improved when watching movies via our home cinema setup. Overall, we’re very impressed – and wish we’d bought it sooner.

Best in Class
[This review was collected as part of a promotion.] Excellent TV at a good price point for OLED Technology. Blown away by it so far and also inbuilt audio is pretty good too
Jay P, Luton, Bedfordshire
A solid oled tv at a reasonable price.
[This review was collected as part of a promotion.] My first ever oled tv, it's vibrant, fast processor, awesome picture quality and good brightness for an oled panel. The remote feels outdated and hassle to navigate through user interfaces.

Amazing TV
[This review was collected as part of a promotion.] From the moment you switch it on, the load up screen colours were so pure. It looks like looking through a window and not looking at a TV. Amazing and I love it.
