Yes, the 27-inch Thunderbolt Display can be set as the primary monitor. However, the 2019 iMac cannot serve as a secondary display. Apple’s Target Display Mode feature, which allows certain iMacs to be used as external displays, does not support the 2019 iMac. For more information, you can refer to this detailed article on Apple’s website: [Target Display Mode](https://support.apple.com/en-us/105126). If you're considering using the Apple Thunderbolt Display 27 alongside an iMac, be aware of these limitations. The A1407 Apple Monitor remains a robust option for primary display use, but compatibility with iMacs as secondary screens is limited.
