Hi guys, I’m having the exact same problems as described in the following forum post (also popos, most recent nvidia drivers, GTX 1660super):

> Thanks for the reply! Here’s the log: [nvidia-bug-report.log.gz](https://forums.developer.nvidia.com/uploads/short-url/74md65Rb9Yj5XeocBkplLo7JNyx.gz) (470.9 KB) I have used this monitor before with MacOS & Windows and they both were able to handle the 100hz refresh rate at any given resolution, however, I don’t know if they were just scaling the native resolution or not. Could you please elaborate on the ModeValidation option — what property should I be setting? Would it be “NoVertRefreshCheck” or some other? Again, many thanks for your help so far!

However, I followed the instructions and I still couldn’t get 1080p@165hz to work (my monitor maxes out at 2k@165hz and 1080p@165hz works on Windows11)

I added the following to my /etc/X11/xorg.conf.d/10-monitor.conf:

```auto
Section "Screen"
    Identifier "Screen0"
    Device "Device0"
    Monitor "Monitor0"
    Option "ModeValidation" "AllowNonEdidModes,NoEdidMaxPClkCheck,NoMaxPClkCheck"
EndSection

```

Rebooted, and got more options available on nvidia-settings, like 1920x1200 scaled. However, still no 1080p@165hz available.

Any ideas? My monitor is KTC H27T22 if that matters. Thank you!

Some more stuff:

My original monitor edid (I’m using a custom one so this one isn’t applied, but probably useful):
