What People Are Saying

Rated 1 out of 5 by from ***B-E-W-A-R-E: This TV has NO audio out*** So you CANNOT simply connect it to your hifi or home theatre amp to get decent sound. And I’m not just talking about digital audio out (optical) – there isn’t even a Mini Jack output. A good screen completely ruined by an absurd oversight that is a total deal breaker.

Rated 5 out of 5 by from Excellent performance at a nice price! Having recently found this model on sale prompted us to replace an ageing plasma bigscreen. It was a breeze to set up and its ample features controvert its price point. We are delighted with the performance of this TV so far and look forward to continued satisfaction with LG quality
