The server uses 3 threads:
- the **main** thread, encoding and streaming the video to the client;
- the **controller** thread, listening for _control events_ (typically,
keyboard and mouse events) from the client.

keyboard and mouse events) from the client;
- the **receiver** thread (managed by the controller), sending _device messges_
to the clients (currently, it is only used to send the device clipboard
content).
Since the video encoding is typically hardware, there would be no benefit in
encoding and streaming in two different threads.

It is possible to turn the device screen off while mirroring on start with a

```bash
scrcpy --turn-screen-off
scrcpy -S
```
Or by pressing `Ctrl`+`o` at any time.
To turn it back on, press `POWER` (or `Ctrl`+`p`).
### Render expired frames
By default, to minimize latency, _scrcpy_ always renders the last decoded frame
available, and drops any previous one.
To force the rendering of all frames (at a cost of a possible increased
latency), use:
