Using Microsoft Remote Desktop with 2 external displays connected to an iPAD using a Thunderbolt dock, the blue in the background turns purple and the gray turns pink. The color change is only on the external displays. When I disconnect one display, the colors are normal. This issue does not occur with a Dell dock. The only difference is the dock and monitor types. This was not an issue until the past two weeks. The displays have no issue when using with a laptop, only when using the iPad.
