I have just purchased a Epson ex5220. I am trying to get it to connect wirelessly with a macbook pro running OSX 10.10 I can get it to connect no problem using Epson's EasyMP software. But my computer does not recognize it as a separate output display. My display settings on my Mac are not updating to show that i have multiple displays connected so i can not accesses the arrangement tab. I need to to display an extended desktop but it only mirrors. Using the option to access the detect display button does nothing. Any ideas would be greatly appreciated.
