Hello, I've been using a 12" PBG4 as a basic media center for watching movies via mini-DVI to composite out, hooked up to an old 4:3 TV. Recently I've purchased an HDTV and am still using the 12" PBG4 as a media center. Obviously, the quality of the video isn't HD (as I'm going out via composite), but honestly, it's good enough (for me anyway). But, my one problem is, the 12" PBG4 doesn't allow me to output the video (either when mirroring the displays or when mirroring is off) at an aspect ratio other than 4:3. Thus, on the HDTV, everything is stretched. To compensate, I have manually distort the aspect ratio of the video I'm watching (through the video software) to make it look the way it's supposed to. This works great for video, but when I do anything else on the HDTV, it's stretched. So, I'm wondering if anyone knows how I'd go about setting an external display to an aspect ration other than 4:3? In the display preferences, all available options are 4:3? Any advice would be appreciated! Thanks, Kristin.
