T470s / 40A2 (M2A0AN3Y) external displays (DP><DVI cant work both) issues after 1903 and BIOS update

2019-09-09, 5:51 AM

Hello everyone,

 

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?

I've tried 

  • 26.20.100.7158 - Latest DHC - no effects
  • 26.20.100.6912 - no effects
  • 26.20.100.6913 - "system doesnt fit actual hardware requriments"

 

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 Smiley Sad

 

Please help since i need both monitors to work Smiley Sad
