markups to OneNote, select Annotate

Drawing on the Whiteboard

Project your screen

Project wirelessly with Miracast
If your laptop, tablet, or phone supports Miracast, you can connect and share
whatever's on your device's screen on Surface Hub without using cables.
The steps to connect wirelessly depend on what type of device you have. If
you're using a PC running Windows 8 or later, press Windows logo key
on your keyboard, and then select the Surface Hub you want to project to.
NOTE If you're using a device running Windows 8 or Windows 8.1 and it's
your first time connecting, select Project and follow the on-screen
instructions to add a wireless display.
Project with cables
Plug a video cable into your device to share your screen. If you want to
control your device with the Surface Hub touchscreen and Pen, plug in the
USB cable too.
When you're done, unplug the cables.
