This looks like a cable/connection/bandwidth problem, which is a very
common type of bug report we receive, but it's not a bug. If the
graphics driver deems the current wiring can't provide enough bandwidth
then it will cull high resolutions and high refresh rates from the list.

Your laptop specs say the HDMI port is "1x HDMI® 2.1, up to 4K/60Hz". So
that's right on the edge of being able to support the monitor's
"3440x1440 100.000000 Hz".

You might be able to solve this by using a higher grade HDMI 2.1 cable.
But that might not be enough if the laptop HDMI port is part of the
problem.

The best solution I can recommend is to instead use the "2x USB-C®
(Thunderbolt™ 4 / USB4® 40Gbps), with USB PD 3.0 and DisplayPort™ 2.1"
ports. You can do that using a USB-C to DisplayPort cable.

Using the USB-C ports will have the extra bonus of not forcing every
frame to be copied from the Intel GPU to the Nvidia GPU, which is an
unfortunate part of the gnome-shell architecture. So you will get higher
frame rates too.
