    I can't duplicate but I can extend - duplicate messes with "active signal" - don't know how...


    I'm running an Inspiron 15 3000 with 10th Gen Intel i5 core. I'm trying to display my laptop's screen on an older 1080p TV, LG 42PQ20.When I "extend" my desktop to the TV, everything works fine and I can see the screen on the TV. However, I really want to "duplicate".When I "extend", everything works, and Advanced Display saysI can't duplicate but I can extend - duplicate messes with "active signal" - don't know how... :Display 1: InternalDesktop mode 1366x768, 60hActive signal 1366x768, 60hDisplay 2: LG TVDesktop mode 1360x768, 60.02hActive signal 1360x768, 60.02hBut then I go to "duplicate", the TV says "invalid format", and Advanced Display saysI can't duplicate but I can extend - duplicate messes with "active signal" - don't know how... :Display 1: InternalDesktop mode 1366x7

    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
