Live Streaming Screen is Black
## Overview If the live streaming screen appears black, there are two common causes. Follow the relevant section below based on your setup. --- ## Reason 1: Using RDP Login **Problem:** In some environments, logging in via RDP (Remote Desktop Protocol) may cause desktop redirection issues, leading to streaming failures. **Solution:** Switch to another remote connection method and restart the rendering service. --- ## Reason 2: Rendering Service Not Started with Administrator Privileges **Problem:** The rendering service must be started with administrator privileges; otherwise, it may fail to operate properly. **Solution:** 1. Stop the Rendering Service. 2. Open the **LarkXR Launch Manager**. 3. Locate the rendering service and select **Stop**. 4. **Start the Service with Administrator Privileges** — right-click to run the following services as administrator.
