detect multiple displays

[MoWiDun]

I have a new switcher and my laptop will not display to or detect multiple monitors. The keyboard and mouse work with the switcher, but not the monitors. What can I do to correct this?

Hi @MoWiDun,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

If your laptop is not detecting multiple monitors when using a switcher, follow these steps to troubleshoot and resolve the issue:
 

Check Connections: Ensure that all cable connections between the switcher, monitors, and your laptop are secure. Confirm that the cables are connected to the correct ports and that they are not damaged.

Verify Monitor Power: Check that the monitors are plugged into a power source and that they are turned on.

Update Drivers: Make sure that the latest display and graphics drivers are installed on your laptop. You can check the manufacturer's website for updates.

Set Display Settings:
 

• Go to the display settings on your laptop. In Windows, you can do this by right-clicking on the desktop and selecting "Display settings."
• In the display settings, click "Detect" to force the system to recognize the monitors.
• Configure the display arrangement as desired, such as extending or duplicating the screens.

Check Switcher Setup: Ensure that your switcher is properly configured. Refer to the switcher's user guide to verify that the setup is correct and all settings are appropriately configured for multiple displays.

Test Refresh Rate and Resolution:
 

• Make sure the refresh rate and resolution settings are supported by both your laptop's GPU and the monitors. Adjust these settings in the Display settings if necessary.

Check for Hardware Limitations: Some switchers might have limitations on the number of displays they can support simultaneously or require specific types of connections.

Perform a Power Cycle:
 

• Turn off the laptop, monitors, and switcher.
• Unplug all connections, wait for a few minutes, then reconnect and power them back on.
  
  I hope this helps.

Take care and have an amazing day!
