Colors display incorrectly

Yes, the colors are correct on any sort of screen capture (PrtScrn, Windows Snip tool).

A couple more data points FWIW:

- If I play any kind of video on the DisplayLink screen, it starts out with the wrong colors for a couple of seconds, then flickers a bit and adjusts to the correct colors and stays correct as long as the video is running.

- If I have both monitors connected via DisplayLink, they both display colors correctly. (This isn't acceptable in the long term, though, because I can't have a 30hz refresh rate on my primary monitor.)

- I haven't gotten into the math, but whatever function the RGB values are going through, it reverses itself. In other words if you apply the inversion twice, you end up with the correct color values. I noticed this when displaying a frame of the above video on the DisplayLink monitor; the incorrect colors in the video were perfectly corrected, while the rest of the screen remained in cuckoo-color land.

Hope this helps -
