Can i just ask exactly what is ISF calibration? I realise it must be some kind of picture optimisation but is it done through software (CD) or is it something you have to get someone who knows to do?
Also, what characteristics does a tv have in order for this? Is it for plasmas & lcds? Where can i check if my tv is suitable for instance?
Sorry for asking what are probably dumb questions, I irritate myself with my lack of knowledge about all this, let alone anyone else!!
