For two weeks now I've not been able to read most of my Scripture slides from my controlling device. The first 3 to 4 letters of each line on the left side do not appear. I have used an I-pad (Apple) and a Google mini (PC). Both have this problem. However, on my PC which is connected to the projector and screen does not have the problem. I have a monitor by the pulpit which also shows what's on the screen. The problem doesn't appear there either. It's only in the control mode where I have the problem.
