What is needed to cast your PC screen to a Chromecast TV in another room? ANT+ usb extender? What is the set up on the PC? Does a wireless usb extension method exist?
You can do chromecast, although the frame rate is incredibly slow. Better off just using a vGA or hdmi cord. You need chrome, and then download the chromecast extention/add on for the browser. The icon will show up in the top right corner- click on that, and below where it says “cast this tab” there should be an experimental option to cast your whole screen.
