I have a laptop with an RTX 3080 and an external HDMI monitor. With 580.95.05 only a refresh rate of 29.94 is available at 1920x1080 on the external monitor, and the monitor itself pops up a message saying it’s an invalid refresh rate. The EDID for the monitor shows 1920x1080@75 should be valid.
Using 570.153.02 or 575.64.05 the external monitor can use multiple refresh rates (75, 60, 50) at 1920x1080 without any problem.
I’ve mainly tested on Fedora 42 KDE Plasma w/Wayland, but have also tried a couple other distros and would be willing to try any requested distro/kernel or driver version. In all cases I’ve tried so far, the external monitor works fine with driver < 580 and fails with 580+.
Here’s 2 bug reports from the same system - Fedora 42 KDE/kernel 6.14.0:
Fedora 42 KDE - 570.153.02 (404.9 KB)
Fedora 42 KDE - 580.95.05 (426.3 KB)
I can also provide nvidia-bug-report from other configurations if it will be useful.
Here’s a snip of xrandr with 570.153.02. Notice the HDMI monitor is 1920x1080@74.91.
Screen 0: minimum 16 x 16, current 3840 x 1080, maximum 32767 x 32767
eDP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 194mm
1920x1080 299.73*+

HDMI-A-1 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 597mm x 336mm
1920x1080 74.91*+
...
And the same snip of xrandr using 580.95.05. Notice the 1st resolution for the HDMI is now only 1366x768@59.62. With Wayland, it seems to automatically, switch to the next lowest good resolution. With X11, it keeps it on the invalid 1920x1080@29.94 and the external monitor is blank except for the error message “Invalid refresh rate”. Unfortunately, 29.94 is the only resolution available to choose from the drop-down.

The following is the output of edid-decode on Fedora 42 KDE Plasma with kernel 6.14.0 and nvidia 580.95.05. I’ve checked the output under multiple other configurations and it’s always the same.
