XFCE Dual monitor display switching change refresh rate

Hi I have dual monitor setup on PC. Main monitor is 75Hz and second one is 60Hz. Everything is ok so far. But sometimes I want to connect my laptop to second monitor (I have 2 cables from second monitor so I don't need to unplug it). So I have xfce4-display-settings --minimal on key shortcut and then select main monitor only and then it runs single monitor. Problem then is my main monitor (75Hz) switches to 60Hz and I have to switch it back in Display settings manually. Is there way so main monitor will allways stays 75Hz and never switches to 60? Not sure if it's xfce problem.

Thank you
