Starting up your Mac Pro

When you start up your Mac Pro, one connected display illuminates initially. 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 adapters 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.
