I really like the Firehawk, and could also recommend most High Contrast Gray surfaced
screens. They will lower the black levels, taking respectable performance to still another level.
These screens will also help out if you have side ambient lighting.
As I said, that works nicely, even at the 128" size.
For those, however, with significant general ambient light, and/or a very large screen, a white
surface with gain, may be your preference. I found the Carada Brilliant White surfaced screen
(a claimed 1.4 gain) that I use in my testing room to be almost, but not quite, too bright at its
106" screen size. But then, all that brightness was killer on sports, at that size, giving you that
plasma display type of brightness. I could watch a pretty good looking image, washed out only
a little, with four overhead recessed lights on full.
To clarify, in the middle sizes, say over 100" and less than 130" diagonal, you'll have to
consider your ambient lighting, and your quest for best black levels, and choose the screen for
you, remembering that with the lower end of that range, the blacks are going to start being a
medium dark gray, with a plus gain screen.
PT-AX200U Projector Measurements and
Calibration
The Panasonic PT-AX200U was off the ideal target of 6500K temperature in all of its Cinema
modes, but correcting the problem was simple.
Cinema 1 mode, out of the box, was somewhat "cool" (bluish), with white measuring at
6999K. The gray points I measure looked like this:
80IRE (light gray) 6950K
50IRE (medium gray) 6890K
30IRE (dark gray) 7215K
Tuning Cinema 1.
As it turns out, for Cinema 1, all it took was going to the main Picture menu, and turning the
Color Temp control down to -2. That yielded excellent numbers, very close to an ideal D65
setup:
100IRE 6607K
80IRE 6540K
50IRE 6355K
30IRE 6616K
Cinema 2 measured 7743K at white (100IRE), also too cool.
Vivid Cinema was more similar to Cinema 1 but with with a wider difference in color balance
between brightest and lowest, in fact almost 1000K range:
100IRE 7729K
80IRE 6587K
50IRE 6286K
30IRE 6473K
