Windows 10: 2 Monitors Are Stuck On Mirror Mode

Hi There,I recently bought 2 Anker monitors and an AMD Mini Pc, The mini PC only has 1 HDMI 1, I bought an HDMI splitter for this. When turned on both screens do show up but they mirror eachother. Instead of allowing it to be one big screen "like drag from screen to screen" the same thing is displayed on both monitors. I tried to go to settings, then display and detect but it does not detect multiple monitors. Anything I can do to fix? The AMD pc has a USB port, should I buy an HDMI to USB splitter instead? Thanks

Setup 2 monitors with different refresh rate in duplicate mode

Hi, СуминНикита

Welcome to the Microsoft Community.



Unfortunately, running two monitors with different refresh rates in duplicate mode may cause some issues. Duplicate mode essentially mirrors the exact same image on both screens. Since the refresh rates differ between your monitors, Windows will default to the lowest common refresh rate to ensure compatibility, which in your case is 120Hz.

To run programs or games at 144Hz on your internal monitor while duplicating the display on your external monitor, you may need to utilize third-party software that can manage this kind of setup, but it may still lead to graphical issues or performance anomalies.

Here are some steps you can try:

1. Set Primary Display:
   
   • Right-click on the desktop and select “Display Settings.”
     
   • Scroll down to “Multiple displays” and select “Duplicate these displays” from the dropdown menu.
     
   • Choose the monitor you wish to set as your main display and check the box that says “Make this my main display.”
     
2. NVIDIA Control Panel (if you have an NVIDIA GPU):
   
   • Open the NVIDIA Control Panel by right-clicking on your desktop and selecting it from the dropdown menu.
     
   • Go to “3D Settings” > “Manage 3D settings.”
     
   • Under the “Global Settings” tab, find the “Preferred refresh rate” option and set it to “Highest available.”
     

Please note that these steps may not fully resolve the issue due to the inherent limitations of running duplicate displays with different refresh rates. It’s generally recommended to use monitors with the same refresh rate for the best performance.

How can I mirror 2 desktop screens onto 2 additional desktop screens?

Trying to find a solution for creating a good "pair programming" environment. One suggested solution involved:

• 1 Desktop
  
• 4 Desktop Monitors
  
• 2 Keyboards
  
• 2 Mice
  

Where, you essentially get two identical setups:

• 2 Desktop Monitors
  
• 1 Keyboard
  
• 1 Mouse
  

Where everything is mirrored. Two people driving the same machine.

I don't believe you can accomplish this with out of the box window settings/features, but is there a way to accomplish this at all? With third party software? With some creative hacking?
