    Dual monitors and only 1 wakes after pc sleeps


    I have an HP Power PC with an Ryzen 7 on Win 10 2004.

    I Recently purchased 2 matching LG monitors which work fine as a dual display setup when the PC is first started. If the pc goes into sleep sometimes only one monitor wakes again. It is not consistent which one will wake, but I would like both to awake. The only way I have found to get them both to work again is to restart the whole machine. This sometimes results in the loss of information if I had things open when it went to sleep.

    Both monitors have their sleep settings set to off.


    Thanks

    :)

    Monitor-1 in dual display would not wake up from sleep.

    Have been using dual display (Dual Smart Solution) for more than two years on Windows 10. Starting around 10 days ago, my major monitor (Monitor-1) would not wake up from sleep. It just blinks when I push the on button. When I unplug Monitor-1, Monitor-2
    would wake up and once I sign in there, Monitor-1 would wake up as I plug it in again. But now that does not even work so I can only work with Monitor-2. Please help, thanks.

    Problem with dual monitors waking from sleep mode.

    try this first. few things can cause this. but go to display settings, select monitor #1 and change resolution to 1280x720, go up and APPLY

    select monitor #2 and set resolution to 1280x720 and Apply on it too, restart pc

    log on and let it sleep and wait 5 minutes and wake and see what happens. you may have to go into safe mode to fix it.
