Azure Virtual Desktop (AVD) is a robust solution for remote desktop services, providing businesses with the flexibility and productivity they require. Yet, encountering a black screen issue in Azure Virtual Desktop can interrupt access to your virtual environment.

In this guide, we will explore the common reasons for this problem, offer troubleshooting steps for Windows 10/11, and provide solutions to resolve it.

What Is the Azure Virtual Desktop Black Screen Issue?

The Azure Virtual Desktop black screen issue manifests when users are unable to view their desktop after logging into a virtual machine, instead facing a black or frozen screen. This can occur right after login or sporadically, impacting productivity. Causes may include graphics configuration errors, RDP settings, network issues, or corrupted user profiles.

Common Causes of the Azure Virtual Desktop Black Screen Issue

• Graphics Driver Problems: Outdated or incompatible graphics drivers are a frequent cause of black screen issues in Azure Virtual Desktop. If the graphics settings in the virtual machine do not align with the remote session's needs, a blank screen may result.
• Remote Desktop Protocol (RDP) Configuration Errors: Incorrect RDP settings can lead to a black screen during the remote session. Issues such as incorrect display settings or hardware acceleration can disrupt the session's performance.
• Corrupted User Profile: A corrupted user profile might hinder the desktop from loading properly, causing a black screen. This often follows a failed update or corruption in login settings.
• Session Timeouts or Network Latency: Poor network performance or session timeouts can cause the remote desktop connection to fail, resulting in a black screen. High latency or low bandwidth can worsen the issue, disrupting the virtual desktop session.

6 Ways to Fix Azure Virtual Desktop Black Screen Issue

Review RDP Settings

To address RDP-related configuration issues, follow these steps:

Troubleshooting for Windows 10/11:

• Launch the Remote Desktop Connection application.
• Click on the Show Options dropdown.
• Navigate to the Display tab and ensure the Display Size is set to an appropriate resolution.
• Turn off hardware acceleration by unchecking “Use all my monitors for the remote session.”
• Click Connect to retry the session.

If the issue continues, adjust your RDP settings as follows:

• Go to Start > Settings > System > Remote Desktop and turn on Remote Desktop.
• In Advanced Settings, confirm that Network Level Authentication is active for a secure connection prior to session establishment.

Update Graphics Drivers

Display issues, like a black screen, are often due to outdated or incompatible graphics drivers. Updating your drivers can fix compatibility issues.

Troubleshooting for Windows 10/11:

• Step 1: Right-click the Start button and select Device Manager.
• Step 2: Under Display adapters, right-click your graphics device and choose Update driver.
• Step 3: Opt for Search automatically for updated driver software. If a new driver is found, it will install automatically.
• Step 4: Restart your system after the installation to apply the updates.

Alternatively, download the latest drivers from the manufacturer’s website (NVIDIA, AMD, or Intel) for your specific graphics card.

Or consider using a third-party PC suite like Fortect, which includes a driver updater.

Fortect is an advanced security suite with real-time malware protection and a driver updater.

Fortect scans all installed drivers, identifies outdated or corrupted ones, such as the display adapter causing the Azure Virtual Desktop black screen, and updates them automatically in minutes. It also optimizes your PC’s performance, ensuring smooth operation of your Windows machine.

Download and install Fortect now.

Restart the Virtual Machine

A restart can refresh the virtual machine, resolving minor issues, including display problems.

Troubleshooting for Windows 10/11:

• Step 1: Go to Start > Power > Restart to reboot the system.
• Step 2: You can also restart the Azure Virtual Machine from the Azure portal by selecting the VM and clicking Restart.

This can clear temporary session issues or configuration errors, allowing access to your desktop.

Clear the User Profile Cache

A corrupted user profile cache might prevent the virtual machine from loading correctly, resulting in a black screen.

Troubleshooting for Windows 10/11:

• Step 1: Press Windows R to open the Run dialog.
• Step 2: Enter %appdata% and press Enter to navigate to the AppData folder.
• Step 3: Find the folder linked to your profile or the Microsoft profile, and delete the cache folder.
• Step 4: Create a new user profile via Settings > Accounts > Family & other users > Add someone else to this PC.

After setting up a new profile, log into Azure Virtual Desktop and check if the issue is resolved.

Verify Network Connectivity

Network connectivity problems can cause session drops or timeouts, leading to a black screen. Ensuring a stable and sufficient bandwidth is crucial for the remote connection.

Troubleshooting for Windows 10/11:

• Step 1: Test your internet connection by opening a browser and confirming that websites load properly.
• Step 2: Use the Network Troubleshooter found in Settings > Update & Security > Troubleshoot > Additional troubleshooters > Internet Connections.
• Step 3: If the connection is slow or unstable, consider switching to a faster or more stable network.

Alternative Windows 10 route:

Settings > System > Troubleshoot > Other Troubleshooter > Network and Internet

After resolving any network issues, test the connection again to see if the black screen problem continues.

Check Azure VM Resource Usage

If your Azure Virtual Machine is underperforming due to high CPU, RAM, or disk usage, it can cause various issues, including black screens. Monitoring and adjusting the VM’s resources can resolve these problems.

Troubleshooting for Windows 10/11:

• Step 1: Log into the Azure portal.
• Step 2: Go to your virtual machine’s dashboard.
• Step 3: In the Monitoring section, click on Metrics to review resource usage (CPU, Memory, Disk I/O).
• Step 4: If resources are fully utilized, consider upgrading to a higher performance tier.

Other Solutions: Azure Virtual Desktop Black Screen

Disable Hardware Graphics Acceleration

Turning off hardware acceleration can often resolve black screen issues due to graphics conflicts.

Troubleshooting for Windows 10/11:

• Open Remote Desktop Connection by searching for it and clicking Show Options.
• Navigate to the Display tab and uncheck Use all my monitors for the remote session.
• Disable hardware acceleration and test the session again.

Update Remote Desktop Client

Ensure the Remote Desktop Client is up to date. Older versions can cause compatibility issues, including black screens.
