    Windows 10 will extend display but won't duplicate

    Trying top duplicate screen to Vizio TV through a HDMI cable. It will perform 2 of the 4 options properly(display to Laptop Only, display to TV only, extend the display between both, duplicate display on both) Results of each:

    1. Display to Laptop ONLY: Works fine

    2. Display to TV ONLY: Works fine

    3. Duplicate the display on both: I get "No Signal" on the TV

    4. Extend the display between both: works fine

    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.

    Windows 10 version 1709 stopped duplicating screens

    Hello,

    my Acer Aspire E112 Win 101 updated to version 1709 just stopped duplicating projector screen (NEC VT57 1024X768) via HDMI without obvious reason. I tried connecting via USB 3.0 to VGAm but it can only extend, not duplicate. Suggestions are welcome. Thank
    you.
