Description

Discussed in https://github.com/rustdesk/rustdesk/discussions/2159

Describe the bug you encountered: Most of our workstations in the studio turn their screens off after 10 min. That's standard and recommended Windows behavior. At that point, Rustdesk can no longer connect to that workstation showing it offline.

...

What did you expect to happen instead? Since the workstations is not offline, just its screen is off, Rustdesk shouldn't declare that workstation offline and just connect to it. ...

How did you install RustDesk?

Research direction
Investigate how RustDesk determines if a workstation is online. Look at the heartbeat or polling mechanism. Check available Windows APIs for detecting screen state (e.g., power events). Consider adding a configuration to ignore screen off status. Refer to the discussion at https://github.com/rustdesk/rustdesk/discussions/2159 for more context. The relevant code may be in the `src/server` or `src/client` directories.
