Hello All. I am looking to upgrade my '14 Mini to an '18 Mini. At the same time possibly changing the monitor to the LG 4K display with TB inputs. I have a PC that also needs to be connected to the same display. Specs for the GPU indicate the USB C port is meant for VR headsets and also supply 23 watts of power. Not sure if the input power will damage the display or not. Also, how would one choose the which computer is being displayed as there are no selection buttons on the display it self. This may be a no go from the get go...
