For some reason my new Dell laptop refuses to work above 30Hz with my monitor at 4K.
This same monitor and cable work just fine over HDMI connected to my Windows box. I haven’t tested this same laptop using Windows since I installed Linux as soon as I got it, but I suspect it’ll work.
60Hz and 75Hz modes are listed, but when I try to use them the screen just goes black without turning off.
