Better still, the amount of green compared to Red and Blue remains virtually unchanged. dropping from 99.99% to 99.98%
In summary, this Elite screen would have to be considered very color neutral, with the shift to red being barely detectable
to the eye, even if you could show the same image with a perfect neutral screen, and then switch back to view the Elite
screen.
The two images below (if you can read the small print - show (first) the color balance measuring directly off of the Optoma
HD7100 projector. (You can see the RGB percentages on the right, and the target slightly off from a perfect 6500K, in the
lower area. The second image shows the numbers and target, with light measured reflected off of the screen.
Projector Screen Image Properties - Evenness of Illumination, Hotspots, Roll-off and "High Contrast"
The original version of this screen, reviewed over a year ago, had a very
visible hot spot, reflecting back light from the projector.
The new R100H1 is greatly improved. So much so, that, the hot spot
and evenness, which were the weakness of the earlier version, are now
a definite strength. There is minimal uneveness which I could barely
detect viewing a pure white image. This image (underexposed by one
f-stop) captured below, exaggerates the differences more than your eye
can see. Even so, you can barely detect the hotspot in the lower center.
I would attribute most of the barely detectable unevenness to the
projector. In this regard, I find the Elite screen, is even better than my
more expensive Firehawk. The Firehawk, does however, offers more
contrast, which would excerbate the tendency to hot spot.
Overall the image illumination appears to be very, very good. Remem-
ber, the Optoma projector used for this shot, only claims 85% evenness
of illumination. (especially seen in the the upper left hand corner)
Roll off, when viewing the screen from off angle is also not significant.
Definitely less than my Firehawk, but again, the Elite doesn't seem to be
be as "high contrast" a screen as the Firehawk. Unless your seating
area will have people sitting more than 45 degrees off angle (rare), I don't think it's going to be an issue.
As you would expect, since the screen doesn't roll off significantly when viewed from side angles, it also means that the
Elite screen won't reject side lighting as much as a higher contrast screen.
