Pros: These are inexpensive and work great. Every one we've used has been simple to install and flawless in operation. For business oriented (non-video) use, the display quality and response is indistinguishable from displays connected to physical video cards. With 1 or 2 of these on a 32 bit system or up to 6 on a 64 bit system, we've seen no problems with memory, system performance or anything else.
Cons: We were unable to get 4 of them to work at the same time on a customer's 32 bit Win7 PC. Initial screen display worked ok, but as the customer ran things that changed what was displayed, all kinds of quirky things started happening and the displays got all messed up. We suspected some sort of memory issue, so we switched to 64bit Win7, and have not had a problem since.
Also, they are not at all useful for streaming images like NetFlix or Hulu. The sound keeps going but the video stalls out.
Other Comments: I have been using 1 of these for about a year on my personal system and got a second a couple months ago. The system they're on (64bit Win7) also has 4 other monitors connected to physical video cards. No problems. As a stress test for a customer, we tried connecting all 6 monitors using Sewell USB adapters for about a day. Again, no problems whatsoever for still images. We have installed 5 of these on customer computers, have no problems and would not hesitate to install more.
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: Worked exactly as expected
Cons: no complaints... probably should get 5 stars, but only in use a few weeks.
