Dear All,
We have a DLP LightCrafter 4500, we want to project a full black image on to the screen. This means there should not be any output because the image is fully black. But surprisingle, the LCR4500 projects a Rectangle of low intensity which is clearly visible.Please see the attached image, where we want to display only circle but the LCR4500 displays a low intensity rectangle around the circle. That means Black pixels of the image does not mean that DMD is completely OFF!!.
Please suggest us solution for the above problem.
Regards
Ramu
