OTOH, you seemed to get 1300-1500 CR with your 71 and now you get 1800-2000 so I guess the CR really is 40% better?! (unless your 71 was poor copy). Do you think the CR increase is real? 40% is a pretty nice sounding improvement.
What do you think of the display, forgetting hard data? How does it compare to your 71 series?
I think the CR improvement is real.
With regards to the improvement in green, I don't know if it is better to move it to where it is or not. I know it is a smaller dE, so presumably it is "better".
When I said the colors could be adjusted with some limitations, I was talking about this issue with green mostly. The setting that moved green is increasing red in the part of the custom color menu involving green. Each of the 6 colors has adjustments that can be made in RGB, and these adjustments seem only to effect the one particular color. In other words by increasing the amount of red in green, the green primary moved closer, but the behavior of red on the other colors was not effected.
Overall I think the color flexibility of the 750 is much superior to the 71. The fact that the color adjustments in the 71 (My Color Control) had no effect is what got me a new 750 in fact. Not TBE or stutter. It is superior and much more complex. So there are probably a lot of "in between" settings that can be tried.
Blacks are better on the 750, as indicated by the better CR.
Clouding is a little more prominent on the 750, but only a little. I am waiting to get a feel for whether my set is average, worse, or better in this regard before I see about exchanging.
I think viewing angle on the 750 is not as good as the 71. My wife and I sit on a 3 person couch, and I notice more of a dropoff from the center position than I noticed with my 71. This is about 15 degrees, if memory serves.
Bottom line: Better blacks, better CR, better color management
More clouding, worse viewing angle
Motion blur about the same, but no TBE (although I havent done the acid test, namely the eagle chase in Planet Earth yet) I didn't get stutter with my 71 except maybe on ABC, TNT, and TBS. I have an episode of Lost on my DVR, and the place that stuttered with the 71 still stutters with the 750, and turning AMP off stops it. The same place doesn't stutter on my Sony HDTV CRT.
