About the shutter
All projectors have a shutter. This can be either a mechanical shutter (on W and U models), or an electronic
shutter (on 4K models). When the shutter is closed, the light source will turn off. When the shutter is opened,
the light source will turn on.
When the light source turns on again, the laser banks have to turn on sequentially, with each type of laser
bank having a different startup time. This may lead to a short timeframe where the colors of the projected
image are not displayed in an optimal fashion.
From software 2.3.8 onward, Barco provides a configuration option for the behavior of the electronic shutter:
• Optimal colors: The projector will wait to open the shutter until all laser banks are fully operational and the
colors can be displayed as intended. The time this takes will vary depending on projector type.
• Fast transitions: The shutter opens immediately and the image will be projected, regardless of laser bank
status. This will cause the projected colors to be slightly “off” for a few seconds until all laser banks are fully
operational.
