Ambient Light Rejection Screens
March 3, 2016,
Given the particular projector and ambient light conditions, the eleven screens in this review produced noticeably different effective black levels. Deeper blacks give the image more snap and sparkle, and you tend to get better color saturation along with it.
However, the perception of black varies greatly depending on the angle of view. Screens with narrow viewing angles may have a clear advantage at the zero degree viewing axis, but lose it rapidly as you move to the side.
An ALR screen's ability to hold deep blacks also varies based on the direction of the ambient light. For example, in these tests the Stewart Firehawk G4 did quite well in holding blacks when ambient light was coming from the side but lost its solid blacks when ambient light above the screen was introduced.
Side Illumination -- Window Light Only
(ambient light from north facing windows
on one side of room; primary concentration of light
striking screens at 50 degrees from center)
Side Window Light and Ceiling Floods
(Ambient light includes both side window light
and ceiling floods above the screens)
