I have the latest generation mini and it runs Leopard. I bought a Samsung P2370 23" 1080p display for it and was pretty impressed. However, I noticed that there is noticeable dithering on some websites (usually with darker solid colors). I went to the same websites on other machines and didnt see the dithering artifacts, so I started to get curious. I popped in an ubuntu live cd into my mini and noticed that I saw NO dithering at all. I've done the calibration under displays, btw. I wouldnt think a ubuntu livecd would show-up my osx install. Any ideas?
