      Hi, so recently I installed MM2 on my RPI with an old Acer X193w monitor which was from 2008.
      The problem I have is when I disconnect my HDMI cable from RPI the monitor does not connect to any other input devices which it used to before. If I connect my laptop or any other HDMI output device, it just doesn’t accept any signal from those but only RPI works with Magic mirror working on it as well.
      Please help me as I am fairly noob in here.
      also, English not being my first language there might be few mistakes.

          @sdetweil yes, it works without any problem if it’s connected to the pi. Only does not display anything saying (no signal) when I connect the same HDMI to a laptop out port.

              @sdetweil unplug from laptop
              power monitor off
              plug on to laptop [NO IT DOES NOT]
              turn monitor on
              does it work??

              unplug from pi
              turn monitor off
              plug onto laptop NO
              turn monitor on
              does it work

              in simple term, display only works if the hdmi is connected to pi and getting input from pi.

                      @sdetweil it does not reset I don’t think it does. because I tried the method you mentioned but it didn’t work.
