SOLVED: Azure Virtual Desktop Black Screen Issue

Azure Virtual Desktop (AVD) is a powerful platform for remote desktop services, offering businesses the flexibility and productivity they need. However, issues such as the Azure Virtual Desktop black screen can cause disruptions, preventing users from accessing their virtual environment. 

We will cover the common causes behind this issue, troubleshooting steps for Windows 10/11, and solutions to fix it.

What Is the Azure Virtual Desktop Black Screen Issue?

The Azure Virtual Desktop black screen issue occurs when users cannot see their desktop environment after logging into a virtual machine. Instead, the screen remains black or freezes. This issue may happen immediately after login or intermittently, affecting user productivity. Various factors can cause this, including graphics configuration issues, RDP settings, network problems, or corrupted user profiles.

Common Causes of the Azure Virtual Desktop Black Screen Issue

• Graphics Driver Issues: Outdated or incompatible graphics drivers can often cause black screen issues in Azure Virtual Desktop. If the graphics configuration in the virtual machine does not match the remote session’s requirements, users may experience a blank screen.
• Remote Desktop Protocol (RDP) Configuration Problems: Incorrect RDP configurations can result in a black screen during the remote session. Problems like improper display settings or hardware acceleration can interfere with the session’s performance.
• Corrupted User Profile: A corrupted user profile can prevent the desktop from loading correctly, resulting in a black screen. This often happens after 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, leading to a black screen. High latency or low bandwidth can exacerbate the issue, disrupting the virtual desktop session.

 6 Ways to Fix Azure Virtual Desktop Black Screen Issue

Check RDP Settings

To resolve any RDP-related configuration issues, follow these steps:

Troubleshooting for Windows 10/11:

• Open the Remote Desktop Connection app.
• Click on the Show Options dropdown.
• Go to the Display tab and check that the Display Size is set to an appropriate resolution.
• Disable hardware acceleration by unchecking the box “Use all my monitors for the remote session.”
• Click Connect to test the session again.

If the problem persists, modify your RDP settings as follows:

• Go to Start > Settings > System > Remote Desktop and toggle the setting for Remote Desktop to On.
• Under Advanced Settings, ensure that Network Level Authentication is enabled. This provides a secure connection before the session is established.

Update Graphics Drivers

Outdated or incompatible graphics drivers often cause display issues, such as a black screen. Keeping your drivers up to date can resolve compatibility problems.

Troubleshooting for Windows 10/11:

• Step 1: Right-click the Start button and select Device Manager.
• Step 2: Expand the Display adapters section, right-click your graphics device, and choose Update driver.
• Step 3: Choose Search automatically for updated driver software. If a newer driver is available, it will automatically install.
• Step 4: After installation, restart your system to apply the updates.

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

Or better yet, invest in a third-party PC suite with a built-in driver updater, such as Fortect.

Fortect is an enhanced security suite with real-time malware protection and driver updater features.

Fortect automatically scans all your installed drivers and identifies outdated and corrupted ones, such as your display adapter causing Azure Virtual Desktop black screen. It will update it automatically in minutes. Once updated, it will also optimize your PC’s performance, ensuring your Windows machine runs smoothly.

Reboot the Virtual Machine

A simple reboot can help refresh the virtual machine and resolve minor issues, including display problems.

Troubleshooting for Windows 10/11:

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

This may clear temporary session issues or settings misconfigurations, allowing you to access your desktop.

Clear the User Profile Cache

If the user profile cache is corrupted, it may 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: Type %appdata% and press Enter to access the AppData folder.
• Step 3: Look for the folder associated with your profile or the Microsoft profile, and delete the cache folder.
• Step 4: Create a new user profile by going to Settings > Accounts > Family & other User > Add someone else to this PC.

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

Verify Network Connectivity

Network connectivity problems can lead to session drops or timeouts, causing a black screen. It’s crucial to ensure stable and sufficient bandwidth for the remote connection.

Troubleshooting for Windows 10/11:

• Step 1: Check your internet connection by opening a browser and verifying that websites load correctly.
• Step 2: Run a Network Troubleshooter by going to 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.

Other Windows 10 route:

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

After fixing any network issues, test the connection again to check if the black screen problem persists.

Check Azure VM Resource Usage

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

Troubleshooting for Windows 10/11:

• Step 1: Log into the Azure portal.
• Step 2: Navigate to your virtual machine’s dashboard.
• Step 3: Under the Monitoring section, click on Metrics and review resource usage (CPU, Memory, Disk I/O).
• Step 4: If resources are maxed out, consider scaling the VM by choosing a higher performance tier.

Other Solutions: Azure Virtual Desktop Black Screen

Disable Hardware Graphics Acceleration

Disabling hardware acceleration can often fix black screen issues related to graphics conflicts.

Troubleshooting for Windows 10/11:

• Open Remote Desktop Connection by typing it into the window search bar and clicking Show Options.
• Go to the Display tab and uncheck the box that says Use all my monitors for the remote session.
• Disable hardware acceleration and test the session again.

Update Remote Desktop Client

Ensure that the Remote Desktop Client is updated to the latest version. Older versions of the client can cause compatibility issues, including black screens.

Troubleshooting for Windows 10/11:

• Visit the Microsoft Store and search for Remote Desktop.
• Click Update to ensure the latest version is installed if an update is available.

Reconfigure Display Settings

Adjusting display settings can resolve conflicts that lead to a black screen.

• Click Connect to test if the display issue is resolved.

Create a New User Profile

If a corrupted profile is causing the issue, creating a new one can help.

Troubleshooting for Windows 10/11:

• Open Settings > Accounts > Family & other users and click Add someone else to this PC.
• Set up a new user account and test if the black screen persists.

Contact Microsoft Support

If all troubleshooting steps fail, consider contacting Microsoft Support for further assistance. They can help pinpoint the root cause of the issue.

Conclusion

The Azure Virtual Desktop black screen issue can stem from various factors, such as graphics driver issues, RDP configuration problems, or network issues. Following the troubleshooting steps outlined above for Windows 10/11, you can resolve the issue and restore seamless access to your virtual desktop. 

Regular maintenance, such as updating drivers, checking RDP settings, and ensuring a stable network, can prevent future occurrences and improve your overall experience with Azure Virtual Desktop.
