The Apple website says that the new 5K studio display is compatible with a wide range of Macs and even some iPad, but the company has told The Verge that it should work fine on a Windows PC. If your PC is capable of outputting to it, the Studio Display should act like a normal monitor with a built-inWebcam and speakers.
Apple's website states that studio display camera features and firmware updates need to be connected to a mac in order to work.
He confirmed that features like Center Stage won't be available. Even though the monitor has a built-in iPhone chip, it's not the case for other macOS-specific features. It seems like it could be possible to summon AirPlay music or Siri on a Windows computer, but Apple said that's only for the Mac.
If that ever changes, you'll have to borrow a Mac to update the display.
The webcam should work with Windows, minus the cool Center Stage feature
Not every computer is able to output a 5K 60Hz signal over the internet, and Apple notes that the monitor's resolution will depend on your machine.
If you only have a Windows computer, the studio display probably won't be a good buy, if you are looking for a monitor with speakers and a webcam. It sounds like you will be fine picking up the studio if you are into Apple's design, or if you switch between a Mac and a PC. We will review the new monitor in a few weeks and see if it's worth the starting price.
