I'm thinking of getting this set. Can someone tell me the following: Can you adjust picture contrast, sharpness etc. in RGB mode? When viewing 4:3 brodcast as widescreen. Is there a mode that compensates for this? ie, panoramic mode where the centre of the picture is normal but the edges are stretched to fill the screen, thus giving an illusion that the picture is actually wide? What do you think of the set's sound and picture? thanks!
