Q1 : Do i need a screen? can i just project it on to my white wall?
A good flat or matte white or gray makes a good surface. A good piece of sheetrock makes a nice screen - if it was hung property and doesn't have a lot of ripples, screws though a "real" screen will offer a different gain performance.
Q2 : What is Silk screen effect?
Silk Screen Effect (SSE) is a visual phenomenon seen in rear-projection televisions. SSE is described by viewers as seeing the texture of the television screen in front of the image. SSE is found on all rear-projection televisions including DLP and Liquid Crystal on Silicon (LCoS). The effect is most visible when viewing bright white or very light colored images. Viewers also report seeing "sparkles" when viewing very bright colored images.
Q3 : What is Screen-door effect?
The screen-door effect or fixed-pattern noise (FPN) is a visual artifact of the projection technology used in digital projectors, where the fine lines separating the projector's pixels become visible in the projected image. This results in an image that appears as if viewed through a fine screen or mesh such as those used on anti-insect screen doors. It most commonly appears as a rectangular grid (hence the name) or sometimes as a hexagonal structure.
