You cannot rely on the projector's default settings; instead, you must manually adjust the image to boost contrast and brightness specifically for the dark surface. This involves lowering the black level to ensure deep shadows remain distinct while increasing the overall gamma setting to lift the image off the dark background.

Understanding Projector Black Wall Contrast Ratio for Sharp Images
This effect is most noticeable in darker rooms where the contrast ratio between the projector's blacks and the wall's blacks is minimized. Look for projectors rated for at least 3,000 lumens, with 4,000 or more being ideal for rooms with any level of ambient light.
