If you want to watch TV on an outdoor projector, you have two main options: a cable box or a streaming device. Cable Box Cable boxes have been around for a long time and can be paired with projectors and TVs. Most new models come with HDMI ports that you can connect with your projectors. The box uses a satellite dish, power cables, coaxial cables, telephone lines, UHF and VHF antennas, and an Ethernet. You have connection options with a cable box, so feel free to pick any of them. Once your TV provider has activated the cable box, you can connect it to your outdoor projector using the HDMI cable for streaming. The second option will be if the cable box does not work for you. Streaming Device Different streaming devices work with outdoor projectors. Streaming devices use a straightforward connection. Google Chromecast Good Chromecast lets you wirelessly connect your tablet or smartphone to the projector. So you can broadcast content from your Media device to the projector screen. Google Chromecast is the device of choice for Android phone users Roku/Amazon streaming stick Roku and Amazon sticks work similarly. All you need to do is plug the stick into your outdoor projector to give you access to various streaming platforms like Netflix, Amazon Prime, Disney, HBO, Hulu, and more. Apple TV Another device you can use to watch TV on your projector is an Apple TV device which takes seconds to connect to your projector. Like Roku, Apple TV gives you access to YouTube, Hulu, Netflix, and many other streaming apps. Your Laptop Last but not least is your laptop. You can watch TV on your projector with your laptop or computer. If you have movie or cable applications on your phone, you can connect your computer to the outdoor projector with an HDMI cable. All you need are the files already saved on your computer or Internet access to download or stream from your computer and project the content with the projector.
