      Hi,
      for installing and configuring my MM I used an old PC monitor. After that I plugged in my monitor for the mirror, rotated it and wanted to put it on the wall, but… now I have the problem that the edge on the bottom and on the right side is missing. So not everything that is in the mirror, is shown on the screen.
      Any solutions for such a problem? I just don’t want to the complete installing again. :(
      Thanks for any help.

        @iamthat79 i think u can set the resolution in the /boot/config.txt like you did the rotation angle…

        search google on raspberry pi rotate screen

          I have already tried to do that. Here are the lines of my config.txt for that purpose. Any mistakes in there?
          hdmi_force_hotplug=1
          hdmi_group=2
          hdmi_group=86
          display_rotate=3

            I have also tried to find out the actual resolution with & /opt/vc/bin/tvservice -s aand that’s 1920x1080. Maybe any chance to tell the pi to somehow reset the input of the hdmi port?

              To change the resolution, run the command sudo raspi-config , navigate to Advanced Options > Resolution, and choose an option. Tells your Pi an HDMI display is attached. See the Raspberry Pi documentation for more hdmi_mode options, and information on /boot/config.txt in general.

              hdmi_group=2
              hdmi_group=86

              you have two hdmi_group statements

              https://www.raspberrypi.org/documentation/configuration/config-txt/video.md

              u have exhausted my knowledge here… others have done this, a search here might help

                Don’t change the resolution, change the overscan setting in /boot/config.txt.

                In your case I assume you will have to play with
                overscan_right
                and
                overscan_bottom

                hope it helps, good luck!
