From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Thanks for the advice, I installed the Debian package "read-edid" and used the get-edid program from it to get the EDID from the monitor. Then I installed the "wxedid" package to display it graphically because the parse-edid program from read-edid didn't work well. According to wxedid there's a seletion of 38402160 modes and some 40962160 modes. So it seems that the EDID is the problem.
