I just bought this TV today, 1. Does anyone have any knowledge of good settings to start off with ? 2. I looked at lots of Sony TV's and even within the sames model some were sharp and some were very soft focus, any ideas would be welcome, is this just a setup problem ? 3. On a PC flat screen it is posible to adjust the "image lock" which can really improve the focus, is this posible with a flat screen TV ? Any comments are most welcome.
