Lenovo X250 Pro Dock causes flickering on external monitor

Hi,

one of the guys at my workplace uses two displays with his X250 and Pro Dock. One of them is an LCD 1080p connected through DP and the second one was an ancient display with 1440x900p panel connected through VGA. Week ago or so the VGA display started flickering, and is unusable for work since it hurts your eyes after a while.

I have tried every solution that was either recommended on the internet or I thought of, yet the problems persist.

Until now, I have tried changing the cable, display, Pro Dock, none of that worked. I also tried installing latest firmware from Lenovo Update for the Dock and latest BIOS. I even reinstalled Intel HD Graphics driver, along with some other drivers from Lenovo support page.

The display works properly when connected directly to the notebook, only in the dock it starts flickering.

 

Is there anyone that had similiar problem and knows how to fix it?
