    TV will properly duplicate laptop screen, but will not extend or work as second screen only


    I usually connect my laptop to my TV via HDMI. It's always been tough to get the second display to work. Usually the duplicate works, and sometimes if I go from duplicate to second screen only it will work. But now it will not work at all. I've updated the graphics drivers and changed the hdmi cable. I did not have this problem with my laptop on my last TV.

  2. my second screen is no longer recognised/working.

    Hi Hans,

    You may have to re-specify the display style on your laptop. There's a possibility that your laptop is currently set to only display the PC screen. Let's change the display style to
    Extend or Duplicate and see if your laptop will recognize your TV as the second monitor/screen.

    By the way, please ensure that your TV is properly connected to your laptop using a VGA, DVI, HDMI or DisplayPort cable, then follow the steps below to change the display style:

    • Press the Windows key + P.
    • In the right pane of your screen, the following display styles will appear:

      PC Screen Only

      Duplicate

      Extend

      Second Screen Only

    3. Select either Duplicate or Extend.

    Let us know how it goes so we can assist you should you need further help.

    Regards.
     
  3. Extending Screen to Laptop

    Pressing MS KEY + P brings up PROJECT which shows display options PC screen only, Duplicate, Extend, Second screen only. After selecting Extent I then click on the “Connect to a wireless display”. Then I select my laptop that is listed.

    That has worked well in the past, but the during a session a few days ago the connection dropped and I have not seen my laptop in the list since.

    I have not found any steps to take that actually address this issue.

  4. TV will properly duplicate laptop screen, but will not extend or work as second screen only

    A third screen appears when trying to duplicate screen to a TV

    Good afternoon,

    I am experiencing a weird issue when trying to project my screen onto a tv in Windows 10 (using HDMI cable).

    My laptop detects the second screen (a samsung TV) and if I am under Control Panel/Display/Screen Resolution, I can see both screens.

    From this same page however, I only have the option to extend my monitor or to show it only on screen 1/2.

    What I am trying to do is to duplicate my screen.

    If I press Win+P, I get that little pop up menu where I do indeed have the option to 'duplicate'. However, if I select duplicate, the following happens:

    -My initial second screen (the TV) stays an extension

    -My laptop screen shrinks

    -Under ControlPanel/Display/Screen Resolution a third screen has appeared. More specifically, what was previously screen 2 -the tv- is now listed as screen 3, and my laptop is listed as both screens 1 and 2.

    If I press 'Identify' both the numbers 1 and 2 appear on my laptop. (They appear as "1|2")

    If I press Win+P again and select 'Extend', the screens go back to normal with the TV being 2 and my laptop being 1.

    All I want is for the my laptop screen to be displayed both on my laptop and on the tv. Any help would be much appreciated.

    Best regards,
