 Does the job as advertisedDec 08, 2009
By Alan M. Carroll
I am running Win7 on a box with a Radeon 4850. I wanted 3 screens but a second graphics card will not fit in the box so I purchased this item. Because of Win7 I had some install problems but I was able to get a driver download from the Gefen website and everything went fine after that. Do *not* use the CD on Win7, get the download and use that. That may change in the future.
As a side note, do not have any other applications up while installing. The install futzes with the displays in a major way and any apps you have up are likely to get confused about what size they should be. It's no problem if you shut them down, install, reboot, and then bring everything back up.
I had one lock up over the night after I installed it (which I fixed by unplugging and replugging the box on the USB side) but that may have been a glitch from failure to reboot after the install issues. I rebooted in the morning for other reasons and it's been flawless in the two weeks since then.
As noted, you can really tell that the graphics are slower than a real video card so you're not going to enjoy graphics intensive games. But for text or slowly updating graphics it's fine. YouTube videos in non-HQ are fine. I am typing this review on it and I can't tell the difference compared to the 4850. I develop graphical applications. Parking the editor on the Gefen and running the app on my video card works very well. Having three screens up is a joy so it's been well worth the money.
P.S. I run the ribbons screen saver and the Gefen can handle that without noticeable degradation.
 Perhaps the best way to run a 2nd external monitor with a MacBook ProFeb 12, 2009
By Paul Lefebvre
I'm using this neat little adapter with my MacBook Pro to drive a 1280x1024 LCD. It needs a separate (free) driver for OS X (available here: [...]), but it works like a charm. The updates are not as fast as a real display, so it's not good for video. But for programming, word processing, e-mail and web surfing it's great.
And I really love having 2 external monitors!
