Hi,
The Apple Studio Display is an older display that was released in 1998 and is no longer in production. If you have an Apple Studio Display and you are using it with a PC, it is unlikely that the speakers will work with Dolby Atmos. Dolby Atmos is a surround sound technology that requires specific hardware and software support. It is not supported by the Apple Studio Display. If you want to use Dolby Atmos with your PC, you will need to use a different display or monitor that is compatible with the technology.
