Hi, I'm thinking of changing plasma to either a 42" or 50" PH9. Actually to my mind the 50 is a bit too big for my room but I wondering it would be favourite if using an external processor. Is it correct that 42" cannot do 1-1 pixel scaling or am I just getting confused? If I'm right and assuming 50" will do 1-1 does this make the 50" a better bet if I'm using a processor (HDQ) for example? Or would I notice any difference anyway? Cheers.
