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?

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

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.

Hi,
mine is working with: types: [diesel", “e5”] in the config-part of the MMM-Fuel module.
