CM3 USB 2.0 to DVI, VGA or HDMI adapters, 2048x1152 pixels, 1080p Full HD possible, external graphics card, display adapter, CM3-NW-004 (Electronics) 4
Use the Winstar to a 1920x 1200 monitor as a second monitor to operate on the desk. The Displayport is therefore already occupied and USB the opportunity to operate the other monitor. After installing the driver MacOSX which I unfortunately had to load from the network, the adapter works since then without any problems. Here the tip to the manufacturer would possibly spend the pennies for a full-size CD because the MiniCD (on, I checked quite very latest Mac drivers) does not fit into the slot drive a Macbook. But after a short search you get the drivers in the network. The large CD there would be the 5th star.
I'll go with the Macbook to the desk, put the USB and DVI port, and both monitors on the desk jump to ... and I can work with an external keyboard and mouse.
Overall, am very pleased with the product and it would also recommend.
