After 20+ years with the same sorry 27" Sharp CRT television, my wife & I bought a Panasonic TH-58PX600OU 58" plasma HDTV. I have read here and there about the desirability of "breaking in" the screen, using lower than default brightness settings, etc. Is this really required? It's not mentioned in the manual. Also, there is much mention (including in the manual) about not displaying 4:3 images for "prolonged periods" (whatever that would be) due to the bars on the sides burning into the screen. Is this much of an issue with a modern plasma? Black bars also appear at top & bottom with other aspect ratios, are these also potentially damaging in "real world" terms? This set is terrific, we had bought a 46" Samsung 1080P LCD & returned it, because the shadow detail, black levels, uneven blacks across the screen, etc., and this one is MUCH more impressive, even though it is "only" 720P. Any observations from the experts here about living with this set in general would be greatly appreciated.
Thanks
