Im using ThinkPad T470s with two external monitors (DELL U2711 DP and CINEMA DISPLAY 23" DVI) connected thru ULTRADOCK 40A2 20V (M2A0AN3Y) with 90W attached.
With INTEL UHD 620 - everything works fine - till i disconnected all cables - and connect them in the new place and after WIN10 update and BIOS update... it stops working
I have actual UltraDock FW - ive tried all mentioned drivers - including actual ones - but the problem still remains. I cant use both DP and DVI monitors at the same time. When i disconnect DP i can use DVI... but not both at the same time like i did before.
What can i do more? During this time ive also update BIOS - so theres maybe some option there? Does both monitors should be checked as DOCK SHARED SCREEN?
Its funny cause when i have my laptop OPEN i can strech my dekstop to two screen (my DELL 27 and ThnkLCD) - but when i close it there is no sign of that CINEMA DISPLAY is connected thru the DVI port. Few days ago the same configurations works fine
Please help since i need both monitors to work
