> The monitor supports 3440x1440 @ 144hz and in the EDID it’s setting that mode as preferred. I checked online and LG market the monitor with those specs, so it’s not an error.

… so did I. There's several models all under the same "brand" name, or whatever hardware manufacturers call the idiocy of sell 8 products under the same name.

Some of them have max refresh rates of 120 Hz. Some can do higher. But the OP never states (unless I am missing it) what model monitor he has.

(There is a model number in the EDID dump but it doesn't seem to correspond in format to LG's model numbers…)
