This is an excellent TV, well worth the price, which is reducing all the time. The set cost £250 when I bought it, and even then it was a bargain.
When set up optimally, there is a 3-D quality to the picture and the sound quality is also good.
To get the best picture, experiment with the settings.
It is best set up to view the Freeview digital channels with the P Mode (on the remote) set to use the Standard option.
There is no way to switch off standby other than switching the set off at the mains, but standby uses only 1W of power, which is next to nothing.
