4K 60Hz

English Hardware
1

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.

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