Actually based on what your saying lower contrast pjs can't do higher gammas because they can't get their Y level low enough for a linear gamma down low. The new BT1886 standard for gamma compensates a bit by using measured black of the particular display and essentially doing an S curve to achieve 2.4 at the upper end. But most displays can't do a higher gamma like the JVCs because they can't achieve the same black or near black levels.

Your 1st sentence is basically saying the same thing as your last sentence so yes, I agree (or am I missing something?). What is your take on BT.1886 - do you use it (or like it)?

Here're two best files for testing motion flow and motion resolution of the PJ or display.
For testing motion interpolation only http://yadi.sk/d/F2cVai5J1zI_O
For testing motion interpolation & motion resolution http://yadi.sk/d/5hHbKKk01zU50
