Pros: Dead simple to set up. Works exactly the way you expect it to.
Other Comments: With multiple monitors on Windows, you'll probably want a couple of freeware programs to upgrade Windows multi-monitor capabilities. I would suggest UltraMon and WinSplit Revolution (I have no connection with either program).
Pros: When it works, it is a seamless thing of beauty.
Cons: When it doesn't, it is frustrating as all hell.
Other Comments: First, let me be clear... these comments are directed more to the OSX Snow Leopard DisplayLink drivers than to this particular Sewell product. In fact, after trying several, this is the one that comes closest to getting everything right.
Unfortunately, the drivers don't play nicely with virtual machines (Parallels, VMWare, etc). With the help of the excellent Sewell tech support, I was able to pinpoint the problem and it worked for a good 10 minutes. But after that, my external monitor will only connect once in a blue moon. If you rely on a Virtual Machine, wait for a bit until the drivers have been updated (currently 1.6b2).
Pros: I am running (3) 19'' at 1280 X 1024 of my 13'' Mac Book and it works fine. Running OSX 10.6. Had a Matrox Triple Head Digital Edition, that did not work with my 13'' Mac Book.
Cons: Computer doesn't like booting with all three monitors. I sometimes have to unplug the USB cable from the Minideck and plug it back in. There is a small amount of latency in the mouse action, but acceptable.
Other Comments: It does what it says. The only solution I have found for my setup.
Pros: Easy to install, I now have three total displays running on my Macbook Pro, makes things so much easier! Highly recommend, for anyone who'd like to expand their workspace. Works well with tiny Netbooks too! Aesthetic wise, compliments my Mac very well.
Cons: None I can think of...
Pros: simple plug and play with usb. superior video image output.
can use more than one on a single computer.
Cons: can't find any
