We have been using OpenLP for sometimes now and recently we found our preachers have to turn around and look at the projector screen to see where they at from the slide during the sermon. So we thought it would be nice to have a LCD monitor facing the preacher so that they can see the PowerPoint without turning on their backs.
Systems: Dell Laptop, Projector and a LCD monitor.
Setup: Using Dell laptop to run OpenLP, used a VGA split cable to connect to the projector and LCD monitor.
Issue: the LCD screen or the projector would show properly if we run it individually (connects to the VGA split cable one at a time), but they won't show the presentation screen simultaneously, when they both connect to the splitter. One time, we did have the system to work: connect VGA splitter to the laptop and on the split side, we connect the projector first, and 5 seconds later connect to the LCD monitor. However immediately, our screen color/brightness reduced in half.
Some people suggests that we get a video booster, but I would like to check in with you experts and see if it is necessary or there is a fix can be done from our OpenLP set up.
Many thanks and God bless your work.
