2.2 Gamma menu
Setting the correct value to the Gamma
Gamma is the relationship between the color values of the data and the color values displayed. The Gamma
coefficient makes it possible to adjust the brightness of the midtones only affecting the very bright and very dark
areas. If gamma is set to high, middle tones appear to dark. If it’s set too low, middle tones appear too light. The
Gamma correction can be set to Normal, Theatre1, Theatre2, Dynamic or Custom.
Normal uses the factory default calibration and will suit most setup.
Theatre1, Theatre2 and Dynamic use lower gamma values that can be directly changed using the RCU by pressing
[Gamma] button, choose the best setting to your ambient environment.
To prevent the lamp lifetime to get shortened, the projector cannot be switched OFF right after the lamp
warm-up. This is normal, wait 60 seconds until you can switch OFF the projector.
Never unplug the projector when it is switched ON, it may damage the lamp.
The Focus and Zoom adjustments cannot be set manually.
