(Church setting) We have a new laptop running windows 10. We have attached a projector via a hdmi cord and all was well. However, we need a secondary screen for the choir to see the display for the words to the songs so we bought a hdmi splitter (not switcher) thinking it would do the job nicely. Here's what happens. Every time we hook up both hdmi cables the projector seems to override the TV screen and all we get on the TV screen is a "no support" message. Unplug the projector and the TV screen shows just fine. It doesn't matter what order I connect the cords or in which output from the splitter. What am I doing wrong???
