The answer is an absolute Yes. You can enjoy Disney Plus via a projector in multiple ways such as Chromecast, HDMI, screen mirroring, Wi-Fi, and more. The simple and the easiest way to use Disney Plus via projector is by using HDMI which takes little to no effort from you. This is just my opinion. You can try any other way to stream the content as per your wish. Not only Disney Plus, but you can also stream similar types of service on a projector such as NetFlix, Hulu, Prime Video, etc.
