4K 60Hz

I bought a new Ryzen7/Vega notebook and when I connect it to the 4K screen (Phillips bdm4065/13779), I see it only gets 30Hz.

Windows does 60Hz.

40" @30Hz really does tire your eyes. Is there a way to activate 60Hz with radeon? This question appears often, but I cannot find an answer.

already solved by plugging into the the other HDMI port of the monitor
one is labled MHL-HDMI the other HDMI :X

actually not. I thought it displayed 60Hz, but that was the supposed warning message for a better resolution. :frowning:

Check the BIOS HDMI version, see https://forums.opensuse.org/showthread.php/539372-4k-monitor-at-30-Hz-max-refresh-rate
