First, the good news: for kicks I decided to try using a USB->VGA video adapter to see if I could get a second monitor in Windows. What do you know, it worked! I used one made by Iogear (model GUC2015V), but all such devices use the same technology from DisplayLink, and should work. So, I can add a second monitor in Windows! (DisplayLink promises Mac drivers in March '08). However, there are two annoyances, which I would love to see fixed: (1) Autoconnect specific USB device. I don't want my VM to connect to most USB devices I use (I have it set to connect to the Host automatically), but it would be useful to be able to have this particular device connected automatically at boot time. This seems like something Parallels should implement in the config file. (And, yes, I know this was discussed/requested in a separate thread last year, but now I'm putting it in "Wish Lists"!) (2) Mouse Sync issue. Although the second monitor works fine, you cannot move the mouse to it when Mouse Synchronization is enabled in Parallels Tools. This makes sense, as the driver obviously has to keep track of where the Parallels window ends so it can switch control, and then it switches to the mac, which doesn't recognize the other monitor. However, in this instance the Windows desktop extends beyond the main window, so the mouse ought to be able to keep going in Windows. If the tools took the size of the Windows desktop into account, it could allow the mouse to keep traveling in Windows, even if it had passed out of the Mac window. (Hopefully that was clear). This might create odd situations where the parallels window is smaller than the mac desktop as the mouse would appear to "jump" across the extra space -- but let's face it, if you are using a second monitor you probably have the Parallels window maxed out (or in full screen) anyway! I have used the second monitor in both Single Window mode and Full Screen, and it works flawlessly in both. It does not seem to interfere with either Spaces or Expose -- I can switch desktops normally. I even kind of works in Coherence mode, but, again, the mouse sync problem prevents the mouse from moving to the other monitor (although you can drag windows on and off the other monitor, and it continues to update windows on that monitor). Turning off mouse sync in Coherence leads to very strange results, as one might expect. Anyway, kudos to the developers for making a stable enough platform that something as wonky as USB video works out of the box. If you can address the two nit-picks above I will be a truly happy person!
