I started out with the Monoprice thunderbolt to dual DVI adapter. The version I have is buggy and won't function properly when coming back from sleep mode. You need to reboot the adapter a couple of times by unplugged the USB cable.

The early Apple thunderbolt dual DVI adapters also reported had problems. However, I have a recent version and the problems are worse. Occasionally when waking up the laptop the screen will have pixel snow. Rebooting the adapter solves the problem.
