    Has anyone had experience using a USB display adapter for multiple monitors on a Macbook Pro? I have a 2011 15" MBP that has 2 USB 2.0 ports. I have looked at several adapters but the ones I saw said that they require USB 3.0 to get a 1920x1080 video output. Does anyone know of an adapter that will output 1080 using my USB 2.0 ports? My external monitor has both the VGA and DVI ports so either one is fine with me.

    Also, how do these adapters perform? Is there any lag?

    If you have just one external monitor, buy one of these cables and connect the Mini DisplayPort end to your MBP's Thunderbolt port.

    Sorry I should have mentioned that. I do have 2 external monitors and I already have one of them connected via the mini display port-DVI adapter

    I used a USB 2 based video card to drive a 1080p monitor on a macbook air for almost a year. It was painful. The menu bar wouldn't render half the time on that monitor, and the refresh rate was laughable. Video playback was hit or miss, and you can't color calibrate it either. However, it was better than nothing. When I upgraded to a USB 3 model I still experienced the same issues, so I don't think bandwidth was the issue.
