Advanced Colour Adjustments
Gamma adjustment
Differences between equipment may result in a slight variation in the colouring when images are projected, and you may want to adjust this. (Projection will stop temporarily during such adjustment.) There are two methods of doing so. One is to select one of the gamma correction values [2.0], [2.1], [2.2], [2.3], [2.4]. The other is customized adjustment, which is done with reference to the projected image or a gamma graph. The gamma graph's horizontal axis represents the input signal level and its vertical axis the output signal level.
■Adjusting from the gamma correction values
From among the gamma correction values [2.0], [2.1], [2.2], [2.3], [2.4], select one that suits the connected
equipment, or one of your own liking, using or , and press or to confirm the selection.
Observe the gamma graph to check the result of the adjustment.
Lower values will increase the contrast of the dark portions but will tend to blur the bright portions. This is indicated by bulging in the upper portion in the gamma graph.
Higher values will darken the bright portions. This is indicated by bulging in the lower portion in the gamma graph.
