Hello at all, after all the time I have found for me the easiest way, to fix my problem. The huge resolution I can change to my normal resolution (1920 x 1080p) if I change something. I saw it in the Internet on another website.
I have to do it like this: 1. Open Terminal 2. Change to root with su. 3. Go with nano editor to >>> /usr/lib/calibre/calibre/gui2/ 4. Open the file >> __init__.py << 5. Go to the line >>> QApplication.setAttribute(Qt.AA_EnableHighDpiScal ing, True) 6. Change the True to the False ans dave it. Finish. That was all, what I have to do and change it. Hope I could help other people. Friendley regards, carlchen
