Custom Resolution Utility (CRU)

[Potty]

Hello! Please help to understand. I have a monitor Gigabyte m27q. When connecting to my old laptop, I cannot use extended 2560x1440 60Hz. Through the program, I realized that I can only use the general pixel frequency limits of no more than 225 Mhz. I don't understand why this is so, because when installing any of the linux, I can use the extension 2560x1440 60Hz as well as 1920x1080 120Hz. On the Windows system, it can only be 1920x1080 96Hz and 2560x1440 55Hz, but no more
