The HD picture quality is outstanding and sound quality is really good. I watched London Olympic games 2012 on this TV and I was blown away by the picture quality. LG's IPS panel has wide viewing angle. I have Toshiba active 3D TV and I did not notice any difference in picture quality with this passive 3D TV after watching kingdom of plants 3D blu ray. If anyone is looking for LED TV with 3D, high quality HD picture with good sound, Look no further, this is the TV for you from top brand.
