Hmm
Jeg mener at have fortået "efter at have læst en del her inde" at hvis man har et helt mørkt rum skal man gå efter et gråt lærred og hvis man ikke kan mørk lægge sit rum helt skal man gå efter et hvit lærred.....
MEN MEN efter at have læst denne test ----> http://www.projectorcentral.com/white_gray_projection_screen s.htm
Bliver jeg sq i tvivl... da den siger det modsatte?!?!?
"Are gray screens still relevant?
We hear claims that today's high contrast DLP projectors have rendered gray screens obsolete. This is not so. It is true that high contrast projectors when used in a totally light controlled environment should be used with white screens. However, a totally light controlled environment entails much more than just being able to turn the lights off. You must consider the latent contrast value of your viewing room as well.
Do you plan to have a dark theater room, with dark walls, ceilings, furniture, carpets? Do you plan to view with no ambient light in the room, just as in a commercial movie theater? If the answer to these questions is yes, then by all means your best solution is a white screen with a high contrast projector. The true videophile will go to great lengths to establish these viewing conditions—this is classic high-end home theater at its best.
However, most home theater enthusiasts don't have the luxury of a dedicated, fully darkened viewing room. Projection systems are frequently set up in living rooms, multi-purpose entertainment rooms, and family rooms that have light colored walls, ceilings, drapes, etc. Thus, even when the lights are fully off, the light being reflected from the screen will bounce off of the reflective elements in the room and back onto the screen. In this situation, a gray screen will be more effective at killing this incident light and thus maintaining deeper black levels on the screen"
