I obtained 3 samples from DaLite as follows (when I indicate lightest, middle, darkest below I'm referring to how they look when put side by side on a table with daylight in the room.
The lightest one is labelled “HD Progressive 1.1 (215355 Sample)”.
The middle lightest one is labelled “HD Progressive 0.9 (21513 Sample)”.
The darkest one is labelled “HD Progressive 1.1 Contrast (11817Sample)”.
I held each up with the projector on to compare to my existing screen.
The HD Progressive 1.1 sample seems to be the same brightness as my current HD Progressive (JKP) 1.3, but doesn't have the sparkle, which is what I’m trying to remove.
The HD Progressive 0.9 sample has no sparkle either, but is just too dark I think given the one above has no sparkle either and is brighter.
The HD Progressive 1.1 Contrast sample seems to match the brightness of my 1.3 existing screen as well when I put it up next to my existing screen (even though it's the darkest one when putting samples side by side on a table). It however has the sparkle, so not good.
I've heard what was posted on this thread about Dalite recommending the 0.9 if you want to remove all sparkles, but given my screen size (138" scope screen), I'm wondering since I don't want to lose too many nits for HDR material, if I'm best to go with the HD Progressive 1.1 (not the contrast one) since it has no visible sparkles and is brighter (by the eye, anyways) than the 0.9.
Also, while my current projector is a JVC X970R, I'll likely be getting a NX9 soon which I believe is brighter.
