Ni Nic,
Please, find attachment in which are Dxdiag when DVI is not working and after override installation without restart when DVI is working.
Also, there are print screens of graphic properties where is clearly visible duplication of monitors to DVI port.
No meters what I do, DVI, HDMI, and DP are not working after restart Windows. Only VGA.
Only solution that I find so far is to after entering Windows is to override installation of drivers and display connectors are in operational mode. Until next restart.
Thank you.
