How to Extend Remote Desktop to Two Monitors

Prerequisites for a Dual-Monitor Remote Desktop Setup

Before configuring a dual-monitor setup for your Remote Desktop sessions, it’s important to ensure your system environment supports this functionality. This section outlines the necessary requirements to avoid compatibility issues during configuration.

Windows Versions That Support Dual Monitors

Not all Windows editions support multiple monitors over a Remote Desktop connection. For this feature, you must have:

Windows 10 Pro or Enterprise: These editions natively support Remote Desktop with multiple monitors.
Windows Server (2016 or later): Server versions allow extensive multi-monitor configurations in enterprise environments.
Upgrade from Windows Home: If using Windows Home, you'll need to upgrade to a Pro or Enterprise version since the Home edition does not support multi-monitor Remote Desktop connections.

Monitors and Hardware Setup

Ensure that all hardware prerequisites are met before initiating your dual-monitor Remote Desktop session:

Dual Monitor Configuration: Both monitors must be properly connected and configured in your local system's Display Settings.
Display Settings: Check that the monitors are set to “Extend” mode under your local machine’s display settings. You can access this through Settings > System > Display > Multiple displays > Extend these displays.
Graphics Drivers: Ensure that your local machine’s graphics drivers are updated. Outdated drivers may prevent the seamless transition between multiple monitors in a remote session.

Network and Performance Considerations

A stable and high-speed internet connection is crucial for a smooth multi-monitor remote desktop experience. Low bandwidth or network instability may cause screen freezing or lag across monitors.

Recommended Bandwidth: For dual-monitor Remote Desktop sessions, a minimum connection speed of 10 Mbps is recommended. Higher resolution displays may require even more bandwidth.
Configure Remote Desktop for Low Bandwidth: In the Remote Desktop Connection settings, go to the Experience tab and select options that optimise performance for low bandwidth environments by adjusting visual settings such as desktop composition and font smoothing.

How to Enable Multi-Monitor Support in Microsoft Remote Desktop

Once the prerequisites are confirmed, you can proceed with enabling multi-monitor support. There are several ways to configure dual monitors in Microsoft Remote Desktop, depending on your preferred method of interaction.

Enabling Multi-Monitor Support in the RDC App

Using the Microsoft Remote Desktop Connection (RDC) tool is the most straightforward method for enabling dual monitors.

Launch RDC: Open the Remote Desktop Connection tool by typing mstsc in the search bar of the Start menu.
Expand Options: Click on Show Options to access advanced settings.
Navigate to Display Tab: In the Display tab, select Use all my monitors for the remote session.
Connect: Enter the target machine’s IP address or hostname and click Connect. Your Remote Desktop session will now be spread across all available monitors.

Configuring an RDP File for Multi-Monitor Setup

For more flexibility or automation in managing Remote Desktop sessions, IT administrators can configure an .rdp file to control the multi-monitor setup.

Create/Edit an RDP File: Use a text editor like Notepad to open or create an .rdp file.
Add Multi-Monitor Parameter: Add or update the following line in the file:

3. Save the File: After saving the changes, double-click the .rdp file to launch a multi-monitor session.

This method is particularly useful for system administrators who manage multiple remote connections or want to preset specific connection configurations for end users.

Use Command-Line for Remote Desktop with Dual Monitors

For command-line enthusiasts and automation purposes, you can initiate a multi-monitor session directly from the Command Prompt.

Open Command Prompt: Run Command Prompt as an administrator.
Execute Command: Enter the following command to start the Remote Desktop session:

This command-line approach is often preferred for quick and repetitive use in IT operations or when handling remote session scripts.

Troubleshooting Common Multi-Monitor Remote Desktop Issues

Even after configuring multi-monitor support, several common issues may arise. Below are the most frequent problems and their solutions.

Second Monitor Not Displaying in Remote Session

In some cases, the second monitor might not display in the Remote Desktop session. This could be caused by improper configuration on the local machine or session settings.

Verify Display Settings: Ensure that the secondary monitor is recognised and set up as an extended display on your local machine.
Check RDC Settings: Double-check the RDC settings to confirm that the Use all monitors option is enabled.
Test the RDP File: If using an .rdp file, confirm that the use multimon parameter is correctly set.

Poor Performance on Secondary Monitor

Lagging or slow response times on the secondary monitor are often network-related or caused by high-resolution display settings.

Adjust Display Resolution: In the Display tab of the Remote Desktop Connection settings, reduce the resolution of the monitors to see if performance improves.
Optimize Network Settings: On the Experience tab, lower the graphical enhancements to optimise for bandwidth-constrained environments.

Session fails to extend across two monitors

If the session is not extending across two monitors as expected, the issue may be due to the Remote Desktop app version or Windows settings.

Update RDC Client: Ensure you are using the latest version of the Microsoft Remote Desktop Client. Older versions may not fully support multi-monitor setups.
Verify Windows Edition: Confirm that you are using a Windows version that supports multi-monitor Remote Desktop.
