赞！海口70岁老人想无偿捐出房子 出去云游看看世界

百度 本报1990年7月30日1版文章《本市二万七千余人脱盲》记载：本市原有文盲3万人，去冬今春一场扎扎实实的“扫盲”，使万人摘下“睁眼瞎”的帽子。

My department has multiple Surface Hub devices around the meeting room floor. We have many instances where it would be helpful to be able to control the devices from a central device - a hub, a computer, or similar. The goal here would be to project a screen, a slide or a video across the devices. 

They are hung on the walls throughout the floor - one example is when we need to usher groups of people back into the main room, we would love to cast an alert on all screens.

Is there a way to do this on the Hub devices? We have considered starting a Zoom or other video call across them all, but that seems like an overly complicated workaround.

Let me know if anyone has any ideas or experience with this.
