@sdetweil Yes, I look directly at the monitor. The Rasp and MagicMirrow system was reinstalled yesterday. So it should be the latest files. So that it goes a little faster, where can I find lsb_release -a and uname-a?
Sorry I am new

Although the installation worked without any problems, I have problems adjusting the display of the mirror to the size of the screen. MagicMirror is not displayed completely, it is obviously too large. I cannot find any reference to this in the documentation. Can anyone help me with a tip on where and how I can change this. Thanks for your help.
