Solved Xorg picks up 60hz instead of 100hz

Hello. I bought a new 24" PC monitor that has 1920x1080 resolution and 100Hz refresh rate. I am using dwm on Xorg and start it by startx and also have .xinitrc but I don't think using xrandr or other programs for that purpose is a good idea. I am trying to set the refresh rate in xorg.conf but it still picks up 60hz. I am using AMD iGPU with 5.15-lts-focal branch of graphics/drm-515-kmod on FreeBSD 14.1-R.

Re: Resolution and VertRefresh

I found a solution after doing some research on the internet: http://forum.xbmc.org/showthread.php?tid=70068

Just added following line to the screen section in /etc/X11/xorg.conf: Modes "2560x1440_30"
Code: 
Section "Screen"
    Identifier     "Screen0"
    Device         "Card0"
    Monitor        "Monitor0"
    SubSection     "Display"
        Viewport    0 0
        Depth       24
        Modes      "2560x1440_30"
    EndSubSection
EndSection

I looked up to this thread but unfortunately, it didn't work for me.

My current xorg.conf is this. I had created it with # X -configure and added Modes "1920x1080_100" to the section which contains Depth 24.

Code: 
Section "ServerLayout"

What happens if VertRefresh is specified?
xorg.conf(5)
Code: 
VertRefresh vertrefresh−range
If this entry is omitted, a default range of 43−72Hz is used.

Thanks. It now picked up 100hz and other resolutions seem gone in output of xrandr but i don't think i would need them.
I wonder, If I had specified a range between 60 and 100, would it still pick up 60hz? I can test it. It did pick up 60hz.
