HoloLens has supported Miracast (screen sharing) with RS5.
How to use is very easy, but PC on the cast side,
One setting was necessary in Windows 10.
Let’s turn this on as the default setting “Projection to this PC” is set to “Always off”.
The operation from HoloLens is Bloom when the application you want to cast is running.
RS5 does not return home and the menu is displayed here.
Since there is a cast button at the right end, it is air tap.
A notice will be displayed on the Windows 10 side after selecting the cast destination, so screen sharing begins if you approve it.
Although there is some delay, I think that it is sufficiently practical speed.
The state of action is here.
アプリ起動中にブルーム → 右端のキャストボタンをタップ → PCを選択
