Hello people, I read today that I can enable HiDPI mode on a Mac that isn't retina. This allows me to get full resolution on my HDTV, which is plugged into my Mac, but still be able to see the UI elements. Unfortunately, I enabled it, and the resolution "960x540 (HiDPI)" does not work. All it does when I click it is make the computer freeze for a few seconds, then change back to the previous resolution. The only other option is "800x450 (HiDPI)", and that is too small a resolution. I currently have the resolution set to 1024x576, but I'd like to get full resolution on my TV. Any help is appreciated.
