Projection Screen Selection
ViewSonic Pro8100’s preset image modes are calibrated based on a no-gain, pure flat white
projection screen. For best preset performance, it is highly recommended to use a no-gain, flat
white professional projection screen. The projection screens used in most office are gain-screens.
Material used in brightness gain screen will cause decrease in viewing angle and hot-spot symptom.
Black level and contrast performances can also be altered by the gain-screen since the gain will
also boost the dark level brightness. The so-called hi-contrast gray projection screen can also alter
the contrast and black level performance. The best viewing performance can not be brought by the
standard factory presets, when using these types of projection screens.
Please seek professional help for adapting a specialized screen, when calibrating the projector
settings manually.
