It's better, but still not centered. Also, there is image that is on the black part at the right and bottom which makes it difficult to calibrate.
Another problem is that the image isn't square...it's more like a trapezoid. Any other tips? Is it advisable for someone to adjust the mounting of the projector?
Completely unrelated question, but there is somewhat of an after image when I change slides (even if the previous slide is only up for a short period of time). This is not something that happened with my other Promethean board located in a different room. Is this normal?
