You can wirelessly project your screen including video (it also transmits sound!) from Windows 10 devices. It connects to HDMI, so if you have something with an HDMI port, like all modern smart TVs, projectors or monitors, you can project onto it. projected on. USB is for power - you can use a portable cell phone charger to power the projection! I will be using it to project onto my students (I'm a teacher) and will be using it with my Surface Book 2's drawing capabilities. Much better than a wired connection. I can walk around the classroom and check people's work and see it on the screen too! Unbelievable.
