Unable to extend monitor display

Hi Jay Jap,

thanks again for your reply.

I checked the screen resolution settings through windows and then through the Nvidia graphics cards.

Windows detected both monitors but Nvidia settings didn't.

I downloaded and installed the Nvidia drivers again and it's working fine. Simple solution, not sure why I had to install the drivers again? But thanks for your help, your suggestion to check if the monitors were being detected prompted me that it had to
be a graphics card issue.

Unable to extend monitor display

Thank you for the information L L33_01. I would like to know more information so that we can pinpoint the cause of the problem:

• May I know what kind of connection are you using(HDMI, VGA, etc.)?
• If you go to the Screen resolution settings, does it detect two monitors?
• Also, since the other screen is blank, does it have an error message?

If the connection worked before you perform you reinstall Windows 7, then let us try to clear the multiple monitor configuration of your monitors, and then extend your display by changing your display settings. Here's how:

1. Press Win + R to open a run box.
2. In the Run box, type regedit, and then click
   OK.
3. Locate the following registry subkey:
4. Depending on your machine, it is either: HKEY_CURRENT_USER\Software\Microsoft\MobilePC\TMM or
   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\TMM
5. Right-click the subkey, then, click Delete.
6. When you are prompted to confirm the delete operation, click Yes.
7. Exit the Registry Editor and reboot your machine.

Once you are back in, try to perform these steps to extend your display:

1. Open Screen Resolution by clicking the Start button ,
   Control Panel, and then, under Appearance and Personalization, click
   Adjust screen resolution.
2. Click the drop-down list next to Multiple displays, click Extend these displays, and then click
   OK.

Note: The manual troubleshooting steps above tells you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection,
back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

For more information about how to back up and restore the registry, you can refer to this
article.
