Can I project images on a colored wall or blackboard instead of a white screen?
You can project images onto surfaces like blackboards and colored walls without loss of image color if you don't have a screen. The projector has a sensor that measures the conditions of the projection surface and automatically adjusts the colors and shading of the image.
To make initial color corrections, press the Wall Shot button on either the remote control or the projector's control panel while projecting an image. Wall Shot's status appears in the upper right corner of your screen. Then you see a sequence of colors flash for approximately five seconds while the sensor measures the conditions of the projection surface and adjusts the image.
When you turn the projector off, the projector stores the correction values obtained by the last Wall Shot measurements. This is useful if you're projecting against the same surface and under the same conditions. To retrieve these corrections, just press the Wall Shot button again while projecting an image.
If you're projecting on a new surface or in a new location and need to readjust the colors:
1. Press the Wall Shot button on the remote control or projector while you're projecting an image. Wait for the Wall Shot status screen.
2. Press the Wall Shot button until you see Wall Shot Readjustment on the status screen. You see a sequence of colors flash for about five seconds as the projector adjusts the color correction values for the new projection surface.
