Starting up your Mac Pro
When you start up your Mac Pro, only one connected display is illuminated at first. Any additional displays illuminate after your Mac has finished starting up. If one or more displays don't illuminate after your Mac has finished starting up, make sure that your displays and any display adaptors have been connected properly.
If you use Boot Camp and install a third-party graphics card from AMD, you may need to use different AMD drivers in Windows.
