I used to have a Mac Mini (4 yrs old or so) that I had connected to a Samsung HDTV @1080i. Just bought the Mac Mini refresh and tried connecting via HDMI. Graphics and text look over-pixelated, sometimes almost illegible, with artifacts at the edges and so on. The same Mini, hooked up via Minidisplay to VGA, looks crisp and beautiful. I went to the Apple Store in Toronto (Yorkdale mall) and had a Genius look at the computer. He (and his supervisor) told me that the crappy graphics from HDMI are standard and the way it is supposed to look. Using a Sony HDTV in the store, they even tested the HDMI on an earlier Mini and it looked the same -- just terrible. I'm posting this account out of surprise really. You'd think HDMI would look great, but it doesn't, and weirdly, VGA looks just fine, much closer to the way a Mac looks connected to a monitor. Also, I have a PS3 and an Xbox 360 connected via HDMI -- they look much better than the Mac Mini. Anyone else think the HDMI signal looks bad?
