# Display Reliability

> How Cyberdriver handles RDP disconnects and virtual displays

The legacy Python Cyberdriver had two separate features for display reliability: persistent display installation and black-screen recovery. Cyberdriver 1.x beta uses RustDesk's display stack instead.

## What changed in Cyberdriver 1.x beta

* RustDesk can create and manage virtual displays.
* Windows service mode can access the login screen.
* The client defaults new Windows sessions toward 1024×768 and adaptive scaling.
* Cyberdriver diagnostics expose Windows virtual-display platform additions so support can see what the display layer is doing.

## RDP disconnects

When RDP disconnects, Windows may remove or change the active display. RustDesk's display service can enumerate displays and, when needed, create a headless virtual display. This is a better foundation than legacy screenshot-based black-screen detection.

## If you see a black screen

1. Open Desktop Tools and check display dimensions.
2. Use diagnostics to inspect `display_dimensions` and `platform_additions`.
3. Try reconnecting the remote session.
4. If needed, use the dashboard's Fix Black Screen tool for legacy machines.

## Persistent display flag

The old `--add-persistent-display` flag is legacy-only. Do not use it for Cyberdriver 1.x beta unless support explicitly asks you to use an old Python agent.
