RDP multiple monitors not working problem
Does the number of locally connected monitors affect the number of monitors connected via RDP? I have 3 monitors connected locally, but only one can work properly over RDP. How can I solve this Remote Desktop multiple monitors not working on Windows 10 problem?”
Many users have encountered the same problem when using RDP to control another PC remotely. But why does it occur and how should it be solved? In the next part, we’ll show you the causes of RDP multiple monitors not working problem and four solutions to effectively solve it.
What causes RDP multiple monitors not working?
There are many reasons why multiple monitors of RDP do not work, mainly including hardware, system version, and software.
- Hardware causes. Hardware causes include display failures, computer host failures, etc., which are generally rare.
- Software reasons. This is the main cause of the problem, but we can solve it through the RDP-related settings.
- System version. This is generally rare but still, needs attention. Because some Windows systems do not support remote control of multi-screen displays, we need to check whether the local computer and the remote computer comply with the corresponding Windows version.
Note: Server users don’t need to worry, because the RDP of Windows Server 2022/2019/2016/2012 R2 all supports multiple monitors. However, there are some restrictions. When connecting to Windows 7 computers, only computers that are running Windows 7 Enterprise or Ultimate can be connected in multi-monitor mode. When connecting to Windows 8.1, only computers that are running Windows 8.1 Professional or Enterprise can be connected in multi-monitor mode.
Four solutions to solve Remote Desktop monitors not working
In the following, we provide you with four solutions to solve Remote Desktop monitors not working, you can choose according to your own situation.
Solution 1. Configure RDP setting
Step 1. Search for Remote Desktop Connection in the Search box. And then open it.
Step 2. In the Remote Desktop Connection dialog box, click Show Options.
Step 3. Go to the Display tab, then check Use all my monitors for the remote session.
Solution 2. Use a command line
Step 1. Press Win + R to invoke the Run dialog box. Then type in “cmd” and hit OK to open Command Prompt.
Step 2. Type in "mstsc.exe /multimon" and press Enter. This will enable multiple monitors on RDP directly. You just need to enter the IP Address and user name to start the remote connection.
If you want to check the connection of multiple monitors, you can press Win + R to invoke the Run dialog box. Then type in “mstsc /l” and hit OK to see the list of all the monitors on the current computer.
Solution 3. Enable multiple monitors directly
Press Win + R to invoke the Run dialog box. Then type in "mstsc /span". It's a bit clunkier than full multi-monitor support as it all appears as one monitor on the client computer but might work for the thing you want along with something like split view.
Solution 4. Change the RDP file
Step 1. On the General tab, click Save As under Connection settings.
Step 2. Enter the File name you want.
Step 3. Find the saved RDP file, right-click it and then choose Open with Notepad. Enter “use Multimon:i:1” and save it. In this way, you can directly enable multiple monitors.
