Windows 10: How to turn my monitors into extended monitors using my HDMI splitter?

I currently have two monitors Sceptre connected through a HDMI splitter to my pc. When I try to hit detect monitors through settings it keep saying, "We didn't find another display". I also have tried "Ctrl+Windows+P" to display options for my screen still no changes. How do I resolve this issue please help.

External monitors extending issue.

I am trying to connect 6 external monitors to my laptop running on windows 10. I am using DVI-D dual-link to HDMI cable to connect the monitors to the HDMI splitter and HDMI to HDMI cable to connect the splitter to the laptop. There
is just one problem when I am extending the screens, the external monitors seem to duplicate themselves rather than extend. So instead of 1 to 7 for all monitors combined, all my laptop only detects 1 and 2. 1 being my laptop and 2 being all the other external
6 monitors. That means that all the external monitors showing me the same thing as in they duplicate and not extend. Any suggestion on it can be fixed so all the external monitors become the extension of my main laptop and do not duplicate?

 

Laptop with HDMI splitter

Dear Dee DR,

Welcome to the Microsoft Community



Thank you for reaching out to us with your concern about connecting two monitors to your laptop using an HDMI splitter. I understand how important it is for you to have this setup working smoothly.

Based on your description, it seems like you're experiencing difficulty getting the monitors to connect through the HDMI splitter. Let's troubleshoot this together:

1. Check Compatibility: Ensure that the HDMI splitter you purchased is compatible with your laptop and monitors. Sometimes, compatibility issues can prevent devices from communicating effectively.
   
2. Verify Connections: Double-check all connections to make sure everything is securely plugged in. Ensure that both HDMI cables from the monitors are connected to the output ports of the HDMI splitter and that the HDMI splitter's input is connected to your laptop's HDMI port.
   
3. Test with Different Setup: If possible, try connecting one monitor directly to your laptop and another through the HDMI splitter to see if both configurations work individually. This can help identify if the issue lies with the splitter or another component. If possible, test with another HDMI splitter to rule out the possibility of a defective splitter.
   
4. Check HDMI Cable Quality: Sometimes, using poor quality HDMI cables can lead to connectivity issues. Try using known-working HDMI cables to rule out this possibility.
   

If none of the above steps resolve the issue, there might be a compatibility problem with your splitter. Consider contacting the splitter manufacturer’s support for further assistance.

If you have any further questions or need additional assistance, please don't hesitate to ask.

The Extended Monitor Does Not Work

Hello.

This problem began with a CCLeaner run.

After I performed the scan/fix, the monitors
suddenly did not display.

I did a factory reset and changed both the
docking station and HDMI cables. Also
purchased a 1-in, 2-out StarTech HDMI
splitter.

These efforts enable two displays in
extended mode, but only the laptop
resolution is visible (Integrated UHD 400)
not the optimal resolution for both the
monitors.

Specs:

• DW1001mw HP Laptop
  
  >> Windows 11
  
  >> Integrated UHD Graphics
  
• Monitor1: HP x27 monitor
  
• Monitor 2: HP z38
  
• Startech USB 3.0
  to 4x HDMI Adaptor
  
• TobenONE USB C Docking Station
  

Flow:

1. Laptop via USB-C/USB-C to Docking station
   
2. Docking station via USB-3.0 to HDMI Adaptor
   
3. HDMI cables (Anker HDMI 8K@60Hz) to monitors
   

Summary:

• The monitors are only displaying the laptop screen
  resolution NOT the respective monitor 1/2 resolutions
