I have an Epson LCD projector at school and would like to link my iPad to it. I bought Apple's Dock to VGA adapter and hooked the two devices together. Not unexpectedly, the Epson doesn't "see' the signal from my iPad. The problem is, an iPad has no F7 key/button to push to link the two (that's the closest device name/brand: Apple). Anyone know of a 'fix"? Or, is Epson just a brand that won't work with the iPad? Thanks!
