  1. Extended Display won’t work but duplicate does


    I have two Acer EI322QUR - 31.5” monitors that I just got. One of the works fine. The other is having some issues. When I try to extend the display the color seems washed and the quality is poor. However using the same cable and laptop I can duplicate the display with no problem. I have tried the other HDMI ports and cables but nothing has worked.

    :)

  2. 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

    Duplicate to extend multiple display control.

    When I switch from duplicate to extend with multiple displays, how can I control which screen automatically shows what was previously on the duplicated screen?

  4. Extended Display won’t work but duplicate does

    Must duplicate display before extending

    After a graphics driver update about a month ago some of my display settings are not working properly, mainly that sometimes my computer will snap out of extending to both my monitors for a number of reasons and in order to get it back I have to first select duplicate, confirm that, and then from there I can get it to extend, if I hit extend first nothing happens. It will sometimes get thrown to one screen or another if a game is having problems, and it occasionally starts up only displaying to the main display.
