I have tested this solution for a few days.
My 4k display is LG 27UK650
I use the connection way as below:
Laptop [HDMI 2.0] <------ HDMI 2.0 Cable ------> [HDMI 2.0] display
At the beginning I can only got 4k@30Hz display via HDMI2.0 <-->HDMI2.0.But I checked the display's manual and it's supported 4K@60Hz only if HDMI ULTRA HD Deep Colour is enabled.I enabled this setting , and I plugged the cable into the HDMI 2.0 port BEFORE the system boots.Display was lit up and got 4K@60Hz.It also supports hot-plugin and display will be lit up fine.It seems to work normally.But it turns into blackscreen and has no signal again when wakes up from sleeping.The HDMI adapter you mentioned in content seems to be lost.
How can I keep the HDMI adapter working all the time ? It will be very appreciated if you could provide me some suggestions.

Also have same case like your, My way to make it work is reboot the display. Obviously it is not the optimal solution for this.
