Yes, the card, cable and monitor are all capable of 4k@30fps. The cable 
and monitor were tested by connecting a laptop running linux mint. This 
gave a 4k display @ 30fps. So for some reason, the card (AMD RX580) 
isn't sending 4k.

Is there a resource explaining how/can anyone tell me how to make the 
card send 4k? The xorg section of the handbook unfortunately hasn't been 
much help.

thanks,
