Projector Brightness and Screen Gain

The gain of a projector screen is the increase in brightness of the image produced compared to a flat matt white

screen. This is given as a simple number, eg 1, 1.5, 2 etc. A gain of 1 means the image is the same brightness as on a flat matt white surface, whereas 2 means the image is twice as bright.

Very High Gain Projector Screens

Typical cheap projector screens have gains of between 1 and 1.2. Gains of 1.5 to 1.8 are achieved with high quality per

Gains of up to 4 can now be achieved with matched projectors and screens.

Color shifting happens due to the surface pr

As combination products don't fit into the traditional categories of drugs, medical devices, or biological products, the USFDA is in the process of devel

In China, the word guanxi is in the top ten vocabulary list of all successful businesses. Great Chinese businesses and business(wo)men just cannot survive and thrive without developing excellent guanxi with organizations of authority, such as the state-owned banks.
