Problem with second monitor.

The last thing I know you can do is download geforce experience from the nvidia website and update your video card driver to the latest, if it doesn't work I'll release your question so that other experts can solve the problem. .

I did this and the graphic card reinstalled by himself, it didn't worked.

Try reinstalling the graphics card driver:

To reinstall the graphics card driver (or any other) in Windows 10, follow these steps:

Right-click on the ‘Start’ button and in the menu that appears, choose the option ‘Device Manager’.

Look for the ‘Graphics cards’ option.

Click on it to expand it and right-click on the graphic and choose ‘Uninstall Device’ and then ‘Uninstall’.

Restart the computer.

Reopen Device Manager. Right-click on the computer's name, which is at the top of the list, and choose the option ‘Scan for hardware changes’ to re-install the previously deleted driver.

Hello how are you?

Welcome to the Microsoft Community!

My name is Marcelo C., I am an independent consultant, I am here to help you in the best possible way.

First check if the monitor option is set to mirror or extend the screen, to check just go to windows+a and select the project option.

If it is already normal check if the windwos is finding the monitor for this you can go to settings>ssistema>display and check if there are two monitors detected.

If the monitor does not appear in the Windows settings panel, please follow these steps before starting to make changes to the software:

Confirm that the monitor is plugged in to power.

Confirm the monitor is turned on.

Restart the computer to force it to detect the monitor.

Use the monitor controls to make sure the correct signal input is selected.

Check the connection cable between the monitor and the graphics card.

Disconnect the connection cable between the computer and the monitor, wait a minute and reconnect it.

Try a different cable to make sure the problem is not with the cable.

Both the DisplayPort and HDMI connection standard are available in various versions, so make sure the cable you are using is the correct one for the version used on the monitor.

Use another connection if the monitor and graphics have more than one.

Connect the monitor to another device to see if the problem is with the monitor.

Use another monitor that you know is working to see if the problem is with your computer.

Disconnect other peripherals such as printers, USB devices or cameras to determine if none of these devices conflict with the monitor.

I hope the information above helps. Please let me know how it goes.

Have a nice day and stay safe.

Marcelo de C.
