Some win 7 PC's may also support Miracast. May help someone else.
I have a PC or Android device. What do I need to stream video?
You also have two possibilities: Miracast or Chromecast.
Miracast is the most feature-rich technology, but not many devices support it. Here are the requirements.
Computers: Many newer Intel-based PCs and Windows 8.1 OS. (If you have Windows 8, you can upgrade to Windows 8.1 for free.) To see if your hardware supports Miracast, from the Start screen, swipe from the right, click "Devices" and then select "Project." If you see "Add a wireless display," your PC is up to the challenge. Some Windows 7 PCs also support Miracast, but it can be a nightmare to figure out. Go with Chromecast instead.
