I have a delicate problem. One of my friends works in a church and they want to show some contents from their iPad, to four monitors for the crowd. - I want the four monitors to act as one. - I need to connect them wirelessly. To find an HDMI splitter is no big deal. But to find something that streams video wirelessly more than 30 feet seems very hard. I was thinking about Apple TV and connect this to the wireless network, but I cannot stream the video to more than one ATV at a time. Right? Any ideas on how to solve this? Cost is not an issue. But they are not able to solve this with cables.
