I have also seen a retailer state that they have never seen screen burn on a Panasonic plasma, even after several months with stationary logos being displayed. However even a fairly new Pioneer had some evidence of screen burn.
LCD though does have the advantage of being available in a far greater range of screen sizes and as already stated does not suffer from screen burn.
Are there any plasma's with a reflective coating ???
I've only seem this on LCD's..
Screen burn is a concern, any links to a plasma, that doesn't suffer ??
The one thing which puts me off Plasma TVs is the amount of power they use and a fact which Mfrs seem to pretty much hide. A 42 inch Plasma uses 260 watts per hour.
The linear assumption is very dangerous here since it is based on a tiny part of what is actually a curve not a straight line (a 0.05 error over just 4 units is quite significant IMO). To disprove: based on the assumed rate of roughly 4.6-4.7w per screen diagonal unit, 14" TVs must only run at 60 watts! Amazing. I should have 14" TVs hanging in my house instead of light bulbs.
I just clicked that pdf out of interest - 5w standby power consumption to an LCD's 1w. Considering most TVs spend more time off than on......
