I set my windows slideshow at 1 minute so it will almost immediately come on when I leave the pc for a break or whatever, what happens is that a blank [black] screen comes on after some minutes so I have to then touch a key to bring back up the main pc screen and wait 1 minute for the slideshow to start again, is there a way for me to have the slideshow stay on all the time [infinitely] until I have to do something on the pc?
