I'm using a DVI->HDMI cable to connect my Powerbook to my Sony LCD TV. The Sony's native resolution is 1366x768. For some reason my Powerbook doesn't want to switch to this resolution. I can get 1280x720, but this leaves a black border around the images the whole time. I've tried setting a custom resolution using the trial version of SwitchResX but to no avail. It won't do it. Anybody have any similar experiences and possibly found a fix? Any advice?
