Hotspotting at 9' Throw Distance
How to get good uniformity at a 9' throw distance?
I currently have two 92" motorized tensioned screens and 2 projectors:
BenQ W1070, poor lense uniformity, 50%
JVC RS45U, excellent lense uniformity, 85-90%, but 3' lower than the minimum recommended throw distance of 12'
XY Screen Black Crystal 0.8 gain, 140° viewing angle
Elunevision 100EL, advertised as lambertian, probably similar to elites cinewhite but with no black backing
Both screens have similar gain aritfacts, maybe the black crystal is slightly more sparkly than the 100ELs sheen. The W1070 is ceiling mounted and the RS45U is on a shelf below the w1070.
Many of the projectors, the nx7, ht9060, vw695, etc., have throw distances of 12', or something like the theo z65 has a 4' min throw distance but poor lense uniformity around 60%.
I have samples of the Snomatte and Parallax but its difficult to tell if there's still hotspotting with small samples.
Will a better screen overcome hotspotting or is it necessary to have the projector at or further than the minimum throw distance? Are there any projectors with lower throw distance that won't hotspot?
