Every now and again I'd like to hook my MacBook (Aluminum/Unibody, last-generation 13") up to my HDTV. Typically this would be to run iTunes with the visualizer for a party, or to watch a movie, and on some rare occasions for training friends on web development.
I use Apple's mini-DisplayPort-to-VGA adapter for this. Every genuine monitor I've plugged into this adapter has detected perfectly (a Dell 19" at work, 1280x1024; my old Acer 19", 1440x900; my current Samsung 22", 1680x1050). However, when hooked into my 720p HDTV, the Mac recognizes it as 1024x768, and doesn't detect any other available resolutions.
Is there a way to force the Mac to use the native resolution (I believe 1366x768 or something similar)? Or am I stuck with this?
It's a Vizio 27" 720p. I don't recall the model number offhand; it's a few years old and I bought it as a floor sample (IE, no manuals).
