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.

You want to look into modifying your display EDID.
I don't believe there's a GUI for this on Linux but this post referencing the Archwiki might come in handy
https://foosel.net/til/how-to-override-the-edid-data-of-a-monitor-under-linux/
I added new refresh rate for testing, but after enabling it I just get black screen.
How to fix this issue?
I'm sorry to hear that. Does this system only have access to this single display? Did you use a kernel command to modify your EDID? If so, are you able to temporarily modify your grub before booting into the OS?
I set modified EDID in GRUB. I have only 1 display.
I see. You can temporarily edit your grub before the OS loads. This should afford you the opportunity to boot into the system without EDID modifications, though im not sure if your modified EDID will still load under this scenario. If so, you may need to switch into a CLI session to undo your changes.
