Great TV for the price
Had TV for 6 weeks now. Got 10% off in the Red10 promotion, so paid only £405 for a 55" Nanocell. Picture fantastic, mainly used for streaming sports. Sound quality is good too, but can be quieter than my old set - volume now 50/100. WebOS UI is a wee bit clunky, had to Google how to have TV default to last HDMI input rather than LG's sales pitch of streamable content. Overall excellent value for money.

Great tv
[This review was collected as part of a promotion.] It's an update for my earlier LG TV. Opened and set up within an hour, and a great picture and sound. A lot more features than previous one, and a lot more ways to set it up which have given more of an experience. Still getting used to it, but the experience up to now is very enjoyable.

TV looks good
[This review was collected as part of a promotion.] Good quality TV - Just noticed one issue till now When the screen refreshes due to buffering issues in video streaming app, the screen had a complete green tint till I exited that video and played it again. If LG team is looking at this review, it could be a software bug that could be fixed in upcoming version. The issue happened on a app for Fire TV stick connected to HDMI. Check for image refresh on TV multiple times and see if that green tinted issue comes up.
