I connected my mac mini core duo (intel) to a Samsung DLP. Works fine with one caveat (not mac specific - in fact, a problem with all TV type displays, I think, but I'm no expert).
When using a DVI cable (inexpensive online, expensive at radio shack, best buy, etc.), the monitor will give you a choice between PC and TV. When you choose "TV", you'll get a perfect dot-for-dot display on the monitor. However, you'll also have an "overscan" problem which I don't really understand but can describe -- the very outer edges of the image spill off the edge of the screen (my uneducated guess is that a portion of the screen is hidden by the frame). Unfortunately, on my screen the cutoff portion includes most of the menu bar. Setting the monitor to "PC" will modestly (5% or so) shrink the image to ensure it fits on the screen. However, this means the monitor is interpolating (no longer dot for dot - which seems to defeat the purpose of DVI) and things get
slightly (and I mean very slightly) fuzzy. Not an issue at all with photos or even video. You can tell the difference on text though. I'm using my mini as a media center so don't care and the fuzziness is so slight it doesn't really bother me when I use Safari but you asked. Again, this isn't a mini issue. You'll get it on any set up using the DLP as a monitor (and that's why Samsung gives you the "PC" option).
On screen resolution, the mini identifies the samsung automatically and will set its resolution to match the native resolution. You'll want to go through the screen calibration preference panel (choose the advanced option) to get the colors just right - takes about 10 minutes. I'm happy with this set up, especially with wireless keyboard and mouse. Remote with FrontRow is great.
Finally, I'm considering using the VGA input. Given that DVI is already interpolating, maybe the VGA will actually be a little sharper.
