Windows 7 - Cannot duplicate the monitor to my Samsung LCD

Hello, everyone!
I'm trying to duplicate a monitor to my Samsung LCD but Windows 7 says that it's unable to save the changes each time I click APPLY after selecting DUPLICATE screens option. WIN+P also doesn't work - I can only see what's going on either on my pc monitor (in Projector Only mode) or TV (in Computer Only Mode).

Both TV and monitor are using 1920x1200 resolution and they are connected via HDMI 1.4, Graphic Card is MSI Radeon 6950.

Any suggestions would be highly appreciated.

 

Duplicate mode on second monitor

I’ve purchased a new monitor and connected it to my HP laptop running Windows 10. It is working without any problems especially in extended mode. But I’d like to work in a duplicate mode. When I
press Windows Key + P and click on the option for duplicate displays, one display goes blank.
Why? Thank you.

Hi,

Your concern about projecting your display to another monitor can be due to the configuration of your device and/or the setup that you're using.
To help us determine the appropriate troubleshooting steps that can resolve your concern, we would like to ask the following questions:

• What’s the current resolution of your display settings in your device? To check, right-click on the blank area of the desktop, choose
  Display settings and click Advanced display settings.
  
• If any, what error messages did you receive when selecting duplicate? If possible, can you send us a screenshot of it?

In the meantime, we recommend that you run the built-in diagnostic tool in Windows 10 or the Windows 10 Troubleshooter. To do this, follow the steps below:

• In the Search box, type Troubleshooting and press
  Enter.
• Click on Hardware and
  Sound.
• Find Hardware and Devices and click on it.

The troubleshooter will perform a diagnostic process on your system that will check and fix issues related to your device.
If the troubleshooter finds any issues, it'll be listed in the result with additional instructions you may need to follow. However, in most cases, the troubleshooter will find and apply fixes automatically.

Give us an update with the outcome.
