Hello I've tried to move the monitor to my other computer and there works flawlessly.....
But on the other computer I dunno why the DP port doesn't let monitor just via HDMI.
There with HDMI as soon as i connected my usb key on the monitor usb it recognized it istantly and there are no problems in the device manager as well.
While on my main rig.... nothing to do.
Now at least I can say that monitor work without defects.....
My other rig has win10 LTSB
I'd like to solve this but I will prolly switch to Intel 8th gen rig moving on from this 6th generation
