    I currently own a 27" Core i7 iMac and already have a 24" BENQ (M2400HD) connected to it via DisplayPort to DVI. I was wondering if using a USB to DVI to display adapter would work with the 1920x1080 resolution.

    What I want to do is buy a USB to DVI to display adapter like the one here: http://eshop.macsales.com/item/Newer%20Technology/VIDU2DVIA/ and purchase the 21.5" M2200HD BENQ monitor to add as the third monitor. I want to be able to utilise the 21'5" native resolution of 1920x1080 with the USB display adapter.

    On the OWC website, it states that the USB display adapter could support resolutions of up to 2048x1152. Do you think that it would be able to support 1920x1080? Most other USB display adapters seem to only support up to 1600x1200 or around there.

    I won't be using the third display for any multimedia - just for web browsing and iTunes to keep the other two monitors clear for other apps.

    Have you looked into Spaces?

    As the website for this USB product states, it supports resolution up to 2048x1152, which slightly bigger than 1920x1080, so it is safe to assume, that the USB product supports an external 21.5"/24" monitor.

    I've used Spaces a few times but I'm not really a fan of having to switch spaces to access my apps. I like to have my apps in front of me on the screen, hence why I want more screen real estate by adding a third monitor. :cool:

    The only concern I have about the USB display adapter is that although it might support high resolutions, it might not support 32bit colour or so. Does anyone have any experience with using these USB display adapters and running 1920x1080 resolutions?
