Hello,
I have an issue setting up multiple monitors on my machine, running RTX 4060 TI. My configuration is the following:
OS: Ubuntu 22.04.4 LTS x86_64 (running XFCE X-server)
CPU: 12th Gen Intel i7-12700F (20) @ 4.800GHz
RAM: 32GB
GPU: RTX 4060 TI (nvidia-driver-550)
I have 3 1440p monitors connected with DisplayPort cables.with default refresh rate of 76 Hz each.
If I connect 1 of the displays and if I am using the default Ubuntu provided nouveau driver → I can get 75Hz on a single monitor, but it doesn’t recognize my other 2 monitors.
If I switch to the driver above (nvidia-driver 550.54.14) - I can connect all 3 monitors, but I can’t select anything above 59HZ in my Display settings nor from the Nvidia Settings app.
The difference is noticeable and I would really like to get this fixed. Any advice is welcome.
All the best,
Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.
I cannot seem to upload the file. The Web UI gets stuck at Processing Upload for 30 minutes even though the file is 244KB. Is there any specific information I can paste here as text or some other way of uploading the file :( ?
Please try to unzip and upload.

Yes, it worked ! Please find attached
The decoded EDID tells this monitor is only capable of 1440p@60Hz, 75Hz only possible on resolutions 1280x1024 and lower. I don’t know how you’ve been able to overdrive the monitor with nouveau.

Not only that !
I’ve been able to run the monitor at 75Hz with MacOs as well (tested on Macbook Pro M2 (16inch) and Macbook Pro 2021 13 inch). I bought 3 identical monitors because I am really happy with colors, refresh_rate, viewing angles etc…
This is probably the crux of the issue…
BenQ also says it’s a 60Hz Monitor, no dice.
why would nouveau allow me to use 74HZ then o.O or MacOS’s drivers. in Amazon it says it’s 76Hz.
Anyway, thank you for your help, I will try to get a screenshot and upload when I get a chance.
Is there a solution for this?
Does Nvidia have a plan to provide a solution anytime soon?
