LE 12 on Rasppberry PI4 no HDMI output on UHD TV

    Fresh install LE 12 on Raspberry PI4 deliver no HDMI0 output when connected to UHD TV (3840 x 2160).

    Comparing LE 12 /flash/config.txt with a working LE 11 show one line difference:
    hdmi_enable_4kp60=1

    When commenting it (#), LE12 put video on HDMI0 and my TV show it.

    So the problem is above line in a config.txt that must be disabled on Raspberry Pi 4 devices. I do not know about RPI 5.

    Developers please consider that change in a next update for the LE 12 image for a RPI 4.

    This indicates you are using an improper HDMI cable or a case with an improper internal HDMI adapter.

    4kp60 was deliberately enabled for RPi4 in LE12 to bring it in line with RPi5 (which has 4kp60 enabled by default).

    so long,

    Hias
