Manually set a display resolution of 3840x2160 using AMD Radeon Control panel

Could anyone help me set up a 4k output manually on the AMD Radeon Vega 11?  I had a fluke after an HP service when a Microsoft Basic Display Adaptor was used temporarily and I had indeed proved that 4 K output was possible with this graphics processor on its DigiPort display (why shouldn't it be except that it was not set up in the driver that was released).  Anyway, if it's because of memory and processor speed, I am perfectly happy to accept a quartering of the refresh rate to 15 Hz in exchange for the 4k resolution that's possible on my TV/monitor.  I tried several numeric variations on the  Front Porch, Sync Width, Pixel Clock, but always come up with a jumbled screen that needs to be reverted back to 1080p.  If someone could help provide a set of numbers for me to try, I'd be very appreciative.
