Windows 10: Can't use duplicate with laptop connected to monitor.

Out of no where I can no longer use the duplicate setting to put the screen of my laptop onto my monitor. I can use all the other ones but when i click duplicate it doesn't do anything. I've tried many things to fix it but nothing has worked.

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.

 

connection problems External Monitor for laptop

If you're trying to use a wired external monitor is it connected to the laptop's HDMI output connector or the mini DisplayPort connector?

If you're using a wired external monitor and don't see any output, right-click on an empty spot on the Desktop and select Screen Resolution -> Detect

In addition, you may need to press the F7 key and select the mode in which the display will function. There are 4 modes:

• Disconnect (or Computer only): display only on the laptop's screen
• Duplicate: the same display on the laptop's screen and the external monitor
• Extend: extends the output so that you can drag things from one screen to the other
• Projector only (or Second Screen Only): displays only on the external monitor

Or are you trying to use wireless (Wi-Di or Miracast)?

 

i have a problem to connect 2 monitors.

Hi Ron,

Thank you for posting your query in Microsoft Community.

• What changes did you make in the BIOS? As making the changes in the BIOS is only recommended by Microsoft if done by the manufacturer.
  

• How are you connecting to the 2nd monitor?

I suggest you to follow the steps from this article below:
