be used in ambiant mode to measure the light projected to a projection

to be the
only one of these devices capable of actually measuring the light
being
*reflected* off the wall or projection screen, thereby measuring
the color
stimulus that reaches our visual system, taking into consideration
the color
of the wall or projection screen. A far better proposition in terms
of color
management. Anyone tried this already?
Now, if only I could find an LCD projector...
I have not used the Eye-One Display, but the Eye-One Pro also reads
the light reflected from the projection surface. Since there is
variation in the color and type of projection screen (e.g. white,
beaded glass, silver), the only way to properly measure a projector
is to include the projection surface in the measurement.
