[Nouveau] NVIDIA(R) NVSTM 4200M

[MM]

I have an old dell e6520 laptop (2013) with the above integrated card.

linux kernel: 6.2.15-300.fc38.x86_64
xorg-x11-drv-nouveau.x86_64    1:1.0.17-5.fc38

>>>> xrandr -v
xrandr program version       1.5.2

Server reports RandR version 1.6
>>> xrandr -q
LVDS-2 connected primary 1920x1080+0+0 (normal left inverted right x axis y
axis) 344mm x 194mm
  1920x1080     60.04*+  60.01    59.97    59.96    40.02    59.93
...
HDMI-1-1 connected 1680x1050+1920+0 (normal left inverted right x axis y
axis) 608mm x 345mm
   1920x1080     60.01    59.97    59.96    60.00    50.00    59.94
 59.93    30.00    24.00    29.97    23.98
   1680x1050     59.95*   59.88

For some reason I am unable to set 1920x1080 for the HDMI.
The HDMI cable leaves the laptop and goes in the HDMI input of a Samsung
U28E570  4u UHD screen.

I have a large amount of nouveau related output in kernel messages,
starting with this call trace:

and more in attached file

1. Can I reach a higher resolution on the Samsung screen?
2. Displaying appears slower (it feels like more CPU is used).  Is there a
misconfig somewhere?
