Unable to rotate & set the correct resolution for Waveshare 7.9inch touchscreen (HDMI version)

Hi,

I made some progress… :slight_smile:

On the commandline, I have to type the following:

export DISPLAY=:0
xrandr --output HDMI-2 --rotate left

Now, I should find a way to activate this automaticaly at boot or startup…

Next step is to correct the touchscreen, because this is not yet rotated…
