The most common cause of a mistaken default resolution is the kernel
randomly not getting enough bandwidth to use the full resolution. This
happens if there is an imperfection in the display cable or its
connections. So I usually recommend replacing the cables between the
laptop and the monitors. For HDMI, try to get an "HDMI 2.1" cable. For
USB-C, try to get "Thunderbolt" cables.
