We'll be away from home for a month, with no cable/TV access but we will have a computer with a ratio 4:3 1024x768 DVI monitor. I'm curious if an Apple TV (2) will work with it. By "working" I mean the video would appear at proper proportion on screen. I'd expect it to be letterboxed, that's fine. Obviously I'd need an HDMI-DVI adapter. Audio isn't an issue; I could either use AirPlay to an Airport Express or through a stereo with optical audio input. Thanks!
