Q&A

Zone dimming on an LED LCD is like an automatic iris in a projector. Using zone dimming will reduce the black level, but it also will introduce artifacts from the LED power level shifting with average picture level. Using this is a personal preference item. Some people will like it while others will find it to be bothersome. These features can alter gamma, brightness and contrast and require visual study to set properly if there is an impact.

Pioneer does not make a 65″ display. If you want the best picture at that size or bigger and the room is dark I would look at front projection. A JVC RS15 or RS20 can be had for that price. I would avoid rear projection they have many issues. Samsung Plasma would be my next choice. Panasonic is coming out with a V20 that may be good if they fix their black level problem.

You do not understand what happens with a CMS. All displays are not perfect. In fact Rec. 709 cannot accurately reproduce a film. The better question is how good can an RS10 or an RS15 look. I would say the RS15 can look very good with careful adjustment. While the RS 10 needs an external CMS to a greater degree. It all comes down to your desire for great color. Without exceptional tools and skill at setup it really does not matter what display you buy it is unlikely you will have any color accuracy or the best look for a display.

I have read a little on this. It is more likely a marketing thing, but the proof will be how it looks. There are not many technical reasons to do this and doing it well would be complex.
