If all else fails, you can plug an HDMI cable into your TV, connect it to your laptop, and play your videos from the Disney Plus web browser. You can Chromecast from any device, such as your iPhone, iPad, Mac computer, Android, or any Google Chrome web browser. If you choose a Google Chromecast plug-in device, you'll be able to cast to your TV using the same method described for Chromecast built-in TVs - the only difference is that you need to plug the Chromecast device into your TV's HDMI port if your TV doesn't have it built in.
If you choose the Amazon Fire Stick or a Roku device, you'll be able to get Disney Plus from your app store in a similar way to the methods listed above for smart TVs. If you don't have a smart TV, you can essentially turn yours into a smart TV using a streaming device that will plug into your TV's HDMI port.
