DL6950 wrong Colors (red swapped with blue)

[Apollo13]

Unfortunately the displaylink team has not been able to find a solution.

It has been a while, but I think I have found a working solution to my issue. I am documenting it here, maybe someone can get some use out of it.

I have multiple monitors attached to my PC; 4 via gpu (2 DP, 2 HDMI) and one via USB-displaylink Adapter. When turning the PC on (cold boot), all screens are turned off. I wait until the boot procedure is complete and then turn on the displaylink monitor first and wait about 3 seconds (in Windows there is an audible sound when one can enter the password). Then I turn on the other monitors.
After logging into windows (when I get an image on all screens), the colors are displayed correctly on the displaylink screen.
This has now worked consistently for about 2 weeks. I can still get the bad colors by turning on the displaylink monitor too soon, or after the other monitors.
