Trapezoidal image
Hello,
I have just installed the ProScreen 4650 and still have two questions.
Since the perspective of the projector is not optimal, I have a trapezoidal image, how can I straighten it? Unfortunately I haven‘t found anything in the menu.
I also don‘t have a power button on the remote control, how do I switch the thing off properly?
Please help urgently
