I don't understand why these problems, which do not exist in Intel HD graphics, exist on Intel Iris

I know this is very annoying, but unfortunately ASUS has limited the HDMI capabilities of this port on their device to 1080p @ 60 Hz. So it is a limitation of the device manufacturer:

Please connect the notebook to the monitor via the DisplayPort protocol instead. This should enable a resolution of 3440 x 1440 @ 144 Hz on the MSI Optix MPG341CQR.
