ThinkPad T460s, extended VGA monitor: part of monitor black

Dear community & Dear supporter

 

systeminformation:

- device: ThinkPad T460s

- dockingstation: ThinkPad Pro Dock (1displayport, 1 VGA, 1 DVI)

- external monitor: Brilliance 220B

 

Problem:

We tried to connect both monitors with displayport & DVI --> DVI monitors stays black

DVI & VGA --> both monitor are working but we have a black part at the right side of the vga monitor (please watch the attached picture).

 

Questions:

I searched for a solution for this problem and i found out, that you can't use DVI and displayport together with the Pro Dock ist this correct?

Does anybody have an idea why there is a black part in the VGA monitor?

 

Current configuration used from the user:

VGA & DVI

 

Already tried:

- switched monitors --> still the same failure with the black part

- switched VGA cable --> still the same failure 

- checked windows resolution and windows / monitor settings in general

- update of the graphiccared and firmware update of the Dock according to: https://support.lenovo.com/ch/de/solutions/ht101460

 

I'm a little bit helpless in the current situation and not sure what i can try to solve the problem. Does anybody has an idea or a helpfull input? I'd appreciate any form of help!

 

Best regards and many thanks in advance!

Right-click the desktop, click Screen Resolution. Can you post a screenshot of that page with both monitors attached?

Dear community

 

We weren't able to solve the problem and bought a new dockingstation with 2 DP's connectors. This solved the problem as somehow the connection with the vga cable didn't work.

 

Cheers
