Adapter allows DVI-over-USB connections

updated 02:25 pm EDT, Wed March 19, 2008


Gefen has introduced a new USB to DVI Graphics Adapter that allows users to connect additional displays Mac OS X systems. This tiny adapter allows a plug and play connection of a DVI or VGA display to any USB 2.0 port so you can add digital video displays or projectors to your laptop and personal computer for simultaneous video delivery without needing a DVI port. Output video is delivered in the DVI-I format, allowing for either VGA or DVI display compatibility.

The Gefen USB to DVI Graphics Adapter is priced at $130 and offers a variety of screen resolutions up to 1600x1200. Users also have the option of having the USB connected display mirror the main display or extend the desktop to provide increased visibility and the ability to view several applications at the same time in a multiple display situation. Testing has shown that up to six USB to DVI Graphics Adapters can be connected to any one system with reliable delivery of video to all six displays.

    Why the h*** is this here

    You're reporting on *Mac*nn. This product is Windows only. Why do you even continue to publish this website, if you are not going to make any effort to keep it relevant to the stated audience? This is an ever-increasing trend here on MacNN... this was once an excellent site for Mac fans, now I don't know why I bother to even come here anymore.

    one one side of the coin

    I agree MacNN has been getting more and more sloppy over the past year and a half_

    In favor of MacNN maybe the above info has merely not been updated on Gefen's product page/website - which in any event MacNN should have mentioned_

    As for the product itself - this type of connection seems rather pointless - seeing as how the thru-put of USB is not sustainable except in low power devices like keyboards and mice_ Much less connecting it to a Digital Video Streaming capable connection_ Has Gefen found a way for high sustainability using USB that the rest of the industry pretends exists?

    re: why is this here

    If it had been posted on Electronista, there would undoubtedly still be people (who apparently can't read)asking why it's posted on Macnn anyway.

    Well, it mustn't be that pointless. They aren't the first to jump into this fray.

    Not only posted wrong

    Not only is this in the wrong place, but the article BODY is wrong: "...allows users to connect additional displays Mac OS X systems."

    Are we missing something here?

    mac support on this prod.

    I agree it's not wholly honest of Gefen to be sending out press releases that their product is now mac compatible. We sell the same thing (along with a few other manufacturers) on our site (same chipset from DisplayLink) but under our name.

    DisplayLink is releasing a Mac driver for this device on March 31st, just around the corner. It will be available on their download site here:

    In the meantime, if you'd like to see one of these in action, you can check our microsite:

    We'll release the latest versions of the driver there as well.
