[QUOTE="krs, post: 1853770, member: 67742"] I don't have an obvious solution, but let me throw out a couple of things: 1. I have used Epson projectors connected to MacBook Pros, usually via a DislayPort to HDMI cable (or adapter with an HDMI-to-HDMI cable) and occasionally had the problem with no display. What eventually worked was trying all combinations of plugging in the cable with the Mac and/or projector powered/non-powered. I just tried all possible combinations - unfortunately I didn't keep a track of what actually worked in the end....but I vaguely remember the "proper way" of plugging in both ends of the cable and then powering up the projector and the Mac did not work for me. 2. On the Apple TV side (and I don't have the product) -are you sure Apple TV can actually output at a 16:10 aspect ratio? From what I have read, it will only output at a 16:9 aspect ratio since that is the aspect rato of all modern flat screen TV sets (and even most monitors) 3. Which Epson projector model do you have? Using VGA connectivity is a step backwards if all your devices can handle digital video. [/QUOTE]
