If your RPi4B's config.txt has a line: hdmi_safe=3D1 then try commenting it out with a # or deleting it. As I understand, the line is there by default because some contexts end up with no display at all without it (blind context). But otherwise it ends up preventing the display size tracking, so there is a tradeoff to having it by default. Technically https://elinux.org/RPiconfig documents hdmi_safe=3D1 as an abbreviated way of saying: hdmi_force_hotplug=3D1 hdmi_ignore_edid=3D0xa5000080 config_hdmi_boost=3D4 hdmi_group=3D2 hdmi_mode=3D4 disable_overscan=3D0 overscan_left=3D24 overscan_right=3D24 overscan_top=3D24 overscan_bottom=3D24 so working based on part of the expanded list might be an alternative in some complicated context. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
