[toggle_content title=”What is a screen gain ?”]
Screen gain is defined as the ratio of luminance produced by a projector’s beam of white, falling 360° onto the screen surface, compared with the luminance of reference standard with gain of 1.0 Reflectance (gain 1.0) measured on a tile of white carbon black.
Simply, the gain of white carbon paper is 1 and the gain of a mirror is 100.
Generally, asthe gain of the screen gets doubles, the price increases two to four times.

[toggle_content title=”3D stereoscopic effect”]
The 3D stereoscopic effect by the left and right viewing angle difference cannot be expressed on flat screens.
The Mocom Solstice Screen (lens-type concaved screen) or cylindrical (curved-type) screens are usually used in various types of simulators to achieve a vivid stereoscopic image.

[toggle_content title=”Flatness of screen”]
The screen’s surface must be flat to achieve uniformity of brightness and resolution.
When a roll-up screen is used for years, the screen’s surface will not have the same flatness and will look like it is curling.
Eighty percent of customers in the world use a fixed-type screen.

[toggle_content title=”Seam of the screens”]
Generally, screens with a size above 100’’ have visible seam lines. It is important to check the thickness and the negative effect of the seams on the image.

[toggle_content title=”Resolution of the screens”]
The rough surface of the screen cannot express high resolution even with the HD projector.
The particles of the screen’s surface are required to be under 20micron for larger-than-100’’ for HD display.

[toggle_content title=”Viewing angles of the screen”]
Generally, the half-gain angle of the screen is defined as 50% of the value of the brightness of the image received in the center of the screen at a zero degree viewing angle. However, it should be applied for normal screens.
The specially designed Mocom Solstice screen with optical lens-like concavature is very different from normal screens. The viewing area of a Mocom Solstice screen must be considered accordig to the width of the screen and the maximum viewing distance.

[toggle_content title=”ANSI Lumen of projector”]
ANSI lumen is a measurement of the overall brightness of a projector. ANSI lumen is calculated by dividing a square meter image into nine equal rectangles, measuring Lux (or brightness), reading at the center of each rectangle, and averaging these nine points. ANSI lumen is, in general, a more accurate measurement of  image brightness than other measurement techniques.
The brightness of the larger screen will decrease proportionally.
The brightness of the screen cannot be resolved by the brighter projector only.
