Hello peeps.
I have just installed an arch install and was trying to crank up the refresh rate of my monitors so i can of course use the full potential of them.
But my main monitor which is connected via a Display Port has flickering horizontal black bars starting from the top. (The higher the refresh rate the more black bars there are where at max refresh rate (144hz) only the taskbar of kde shows).
My monitors model is Benq Zowie XL2411P.
And this is happening on a system with an nvidia graphics card 1660 super.
This is footage from my phone showing how the black bars are being displayed (Sorry in advance cause of the phone videos only way i could capture this): video
Notes: This is not happening via the HDMI port on the other monitor.

Please post the output of "xrandr --verbose" and your Xorg log, https://wiki.archlinux.org/title/Xorg#General
Also suspend the compositor (SHIFT+Alt+F12) to make sure it's not just that.

This is the xrandr output: https://srcb.in/yiA2vgsxdK
And this the Xorg.0.log file: https://sourceb.in/2Amw3tNs4r

The xrandr output is from a wayland session, depite the xorg log.
Try the behavior w/ an X11 session and post
xrandr --verbose | curl -F 'file=@-' 0x0.st

This is the result of it https://srcb.in/IvSBTRf21n
Same happens with a X11 session.

The same output is on HDMI and DP, the 1920x1080@120Hz are the the default CVT1 reduced blanking
The 1920x1080@144Hz modeline is pretty aggressive and below CVT12 (but afaiu 120Hz is problematic as well?)
Both would still exceed DP 1.0 (you need DP 1.2) but you've a Turing chip
… that you're running on nouveau.
=> Install and try the binary nvidia driver.

Yes every refresh rate above 87 is problematic, altho i do not understand what you are saying by binary nvidia drivers.

Is the display cable *very* old (or very cheap

Oh jesus the problem was with the nvidia package cause i didn't know that my graphics card would require another package as its not really that outdated. Thanks for the help.
And no the display cable works just fine ain't old nor cheap.
