2 External Monitors - USB to VGA

Hi all,

So i've just bought the new 21" iMac and I'm trying to connect up my 2x external dell monitors. The 2 monitors only support VGA.

Where this specific iMac only has 1x thunderbolt port, I can only make use of 1 mini-dvi to vga connector. I need to connect up the second monitor presumably by using a USB to VGA adapter. The USB to VGA adapter I just purchased isn't compatible with mac!

Could anyone please recommend a USB to VGA adapter that's compatible with Mac please??

Much appreciated,

Jamie.

Matrox makes some 2 and 3 screen adapters:

Mind you depending on your GPU, you may get significant slow down in rendering. But at least you can setup your system with whatever layout you desire. Make sure the adapter you get is Thunderbolt compatible.

Have another look at their website, and consult with them. I believe they have some solutions that require no USB.
