I just got a Micr/Mini DVI to DVI adapter (the Apple one) from Microcenter, along with a male-to-male DVI cable so I could hook up my black Macbook to my 22" Samsung monitor. It works perfectly so far and I checked out the preferences for displays in OS X as well. Now I'm a bit confused.. So, my Macbook still shows its regular image as I'm used to. The monitor now acts as a second display as far as I can tell. If I follow my mouse cursor on the Macbook and move it to the right edge of the screen, it shows up on the left edge of the monitor. When I move the cursor to the left edge of the monitor and keep going, it shows up on the Macbook again. So far, so good.. but just how does this work? I don't have a dock on the monitor. To access the dock, I need to go back to the Macbook's screen. Same with the menubar.. on the monitor, all I see is program windows but no menubar. I tried "mirroring" the displays and it looks like that give sme what I wanted.. (even though this second display idea is pretty cool!), namely to have whatever I see on my Macbook on the monitor, 1 to 1--with a huge caveat: the display resolution, when mirrored, looks like crap on the monitor. It's all muddy.. I assume that's because the Macbook tells the monitor to use the same resolution as the Macbook, the latter of which of course has the lower resolution (hence the term "mirroring". Now.. is there a way to have the image on the monitor display at its native resolution, have it looking sharp in other words (like it does right now), WHILE mirroring? Any other tips for this kind of setup? Thanks! (BTW, it's pretty crazy looking at this comparatively huge monitor running OSX when all I'm used to is the 13" screen of the Macbook ) UPDATE: Another thing I don't see on the extended monitor: the app switcher (command+TAB). I read Apple's help file on the topic in the meantime, and it looks like mirroring displays requires them to be running at the same resolution. Shame, even though it makes sense.
