Let me start by advising you that I am quite new to all this. I recently purchased a Samsung LE40M86BD. I was talked into buying all the usual "good" cables etc, but my picture is not to the standard I was hoping. Having read a fair bit before I took the plunge I realise the the general opinion is that the picture from an old CRT set will be better than lcd or plasma, but some of the channels are truly awful. I get a lot of blurring of people when they move and some channels are really bitty and grainy. Is there anything I can do to try to resolve this or is this just the way it is? Thanks in advance. Edit : I see people referring to calibrating their sets. Sorry I don't know how to do this?
