Windows 10: Two monitors connected but they show as one ultrawide display

I have 2 monitors for my computer set up. But I don't know why, the display become ultrawide 3840x1080p as one display on 2 monitors, but the 2nd monitor isn't detected in the system. In advanced display settings, it only shows 1 monitor. I want to change it to the extended 2 monitors detected as usual where I can use each monitor for specific purpose, not as a single fullscreen display on 2 monitors. Please help.

Two monitors connected but they show as one ultrawide

Hi Safra N,

Thank you for reaching Microsoft Community. We appreciate for sharing your concern to us.

I am aware that you are having issues using a dock to connect your Surface laptop to two external monitors. I am here to help and let us work on this together. Allow me to ask some question.

• What kind of dock did you use to connect with your Surface laptop?
  
• What is the make and model of the external monitor?
  
• What version of Windows are you currently running?
  

To separate the monitor from the ultrawide display, kindly try the following steps below.

1. On your desktop, select Display settings by doing a right-click.
   
2. Click on Detect after swiping down to the Multiple displays section.
   
3. Click the second monitor once Windows has identified it, then choose "Disconnect this display" from the Multiple displays drop-down box.
   

This should detach the monitor from the ultrawide display.

For other troubleshooting guide, follow the solution provided from this article Troubleshoot connecting Surface to an external display - Microsoft Support.

Kind regards,

Lavenia

 

Two monitors connected but they show as one ultrawide

I am using a Surface laptop 4 with it's dock to connect two external monitors.

After not being able to load both displays when they are connected to the dock (one shows, other is not detected) I tried connecting one to the dock and one directly to the laptop's usb-c port and now it's detecting both monitors as one, resulting in an ultrawide like display (3840x1080 resolution) across both monitors.

How can I "detach" the other monitor so they work independently?

Thanks!

Correct monitor display resolution unlisted when second monitor is connected

I am attempting to connect my laptop (Dell Inspiron) to a dual monitor arrangement (one 1920x1080, and an ultrawide 3440x1440). When either single monitor is connected, the display resolution is correct and everything works well. However when connecting the second monitor, the resolution of the ultrawide reduces to 1920x1080, with no option to increase this. 3440x1440 is also not displayed in the 'list of valid modes' accessed under advanced display--> display adapter properties --> List all modes.





I have checked graphics, and display adapter drivers and confirmed that the most up-to-date is installed. I have performed multiple system restarts, but I'm confused why the problem only occurs when a second monitor is connected. The correct 3440x1440 resolution option is available and works well when the ultrawide is the only monitor in use.
