The projectors should be set up as appropriately as possible.
Here, particular attention must be paid to the sharpness, the coverage of the entire area to be played, a sufficient overlap (10-15%) and an initial adjustment of the brightness and the color space.
For a good result it is recommended to operate the projectors in SRGB / Cinema / Multiprojection mode, often a better blending result is also achieved if the projectors are not driven at the maximum brightness level.
It is not advisable to mix projectors of different technology (e.g., DLP / LCOS / LCD / LED).
A common problem is the use of ultra-wide-angle projectors on round surfaces – please note that only a few types of projectors are suitable there to produce a homogeneous image in high quality
