GrayHawk RS G3 -
This material was very color neutral. It appeared to have a very smooth surface. It also had many sparkling elements to in- crease the screen gain. The shimmering caused by these elements was visible at moderate light levels with images, but a little less than the Fire- Hawk material. The actual gain of this material was not high enough to offset the light lost by the dark gray tint. This material is intended to aid in rooms with significant scattered light from walls and ceilings. It is a special use material that should be considered with care.
HD Progressive 0.9 -
This material is very color neutral. It appeared to be a very smooth surface.. It also has a very slight sheen to it which was visible on images infrequently. This may explain its gray coloring and yet a gain very nearly 1.0. It did not add much character to the image. This material is designed to aid with rejecting light from reflections and may help in that situation.
HD Progressive 0.6 -
This material is very color neutral. It appeared to be a very smooth surface. It also has a very slight sheen to it which was visible on images infrequently. The sheen on this was stronger than the HD Progressive 0.9 sample. This material would require much more light to illuminate the same screen size than any other sample tested here. A product like this is for special circumstances and would not fit most peo- ples requirements.
