Raspberry Pi4 4k 60Hz LibreELEC 10.0.2

The obvious Q is .. do you actually have 4K60 media (other than test media)? .. If the answer is 'no' then don't worry about something that you don't need. Most people do not need 4K60 modes. NB: Some TVs only support 4K60 on specific ports .. no idea about the C1 but it might be worth experimenting with different ports and seeing if needs to be enabled in menus on the TV side.

For 4kp60 to work you need hdmi_enable_4kp60=1 in config.txt and also enable "Ultra HDMI deep color" on the HDMI port in your TV's settings.

Are you sure, that "Ultra HDMI deep color" is mandatory? I mean this wording, or is it enough that the monitor supports 10bit?

I am asking this, because I can't get 4k@60Hz work with my PI400 and a ASUS PA328Q , but this monitor works with 4k@60Hz and a dvb/enigma-box. See attachment.

So this means that monitor supports 4k@60Hz, but maybe there is a limit from the side of the PI400.

No idea about that Asus thing though.

To make it clear, the Asus is a professional pc-monitor.

Be immersed in stunning 4K/UHD visuals with the PA328Q. It is equipped with DisplayPort 1.2, mini-DisplayPort 1.2, two HDMI ports, and a HDMI-1 / MHL 3.0 port*. PA328Q supports 4K/UHD content playback at 60Hz through HDMI-1 port or DisplayPort 1.2

1. HDMI-1 port supports 4K/UHD playback at 60Hz and the YCbCr 4:2:0 color format

2. HDMI-2, HDMI-3, and MHL 3.0 ports support 4K/UHD playback at 30Hz

Since the monitor supports YCbCr 4:2:0 only, I am guessing, that the enigma-box AX HD61 supports YCbCr 4:2:0 and therefore it works.
