O.K. here's what I found doing a simple test with the three materials side
by side.The Vikuity definitely has the best blacks,without compromising
the brightness.The high def acrylic had the most brightness with excellent
blacks and the cyro had excellent blacks but seemed a little bluish on the whites.
The problem with the vikuity is it's manufactured to a maximum of 48"
high(comes in a roll) so roughly a 96" screen is max in 16X9.Too small
for my purpose.Excellent...
