keep in mind I grab the driver directly from the site so it have the latest version . now from the very begin this thing cause my computer to crash and restart . the first time I notice this be less than a hour after install when I lock my computer to go take my break from work , come back and my co-worker say to box restart . so I log back in and within about 10 minute it happen again . so I disable the third monitor , restart again . Unplugged the usb device and it still restart . only after uninstall the driver do my computer stop restart . they say it work with Windows 7 , well yeah but it fail horribly .
