Thanks for the response. I should have given more info. My resolution for the second display is set to 1920×1080. I did set the background on the desktop to all black and I also hid the task bar.
The images being projected while actually printing a layer is perfect. Once it the layer is done, everything goes black, but a small, very dim, white line that is oreiented at what would be the bottom of the projector lens. When I look at the second display box run by the Kudo softare, that white line does not show, so I was wondering if it’s a setting on the projector itself??
