Been having this issue, Lenovo X1 Carbon 3rd generation is docked into a ThinkPad OneLink Dock. Using two 22 inch ViewSonic external monitors. The external monitors will flicker. Some days they won't flicker at all, some days they will flicker 15 times in a minutes.

I have reinstall the video drivers, replaced the dock, replaced the DVI cords. Any other ideas?


Try updating your BIOS:

From the BIOS changelog:

<1.11> UEFI: 1.11 / ECP: 1.06 - (Fix) Fixed a flicker issue on an external monitor via OneLink Pro Cable Dock.

Double check that the BIOS matches your machine etc. first.
