I can’t confirm, as I don’t have a touch Pi screen, but no. A screen with a USB touch cable will.
Also, apparently the 10556 update didn’t have anything specifically in the Windows 10 IoT Core side that enabled the DSI to work, there was also a firmware update in the image, and that appears to have been the lucky change
@ munderhill - That was my first problem as well …
at first I used raspian with update/upgrade as a ref since it works there (b4 10556). I did this just to confirm the display is working from a HW point of view. It is there where I found out that the cable is a little bit tricky … but in the end it turns out to be just fine … cool little display. Too bad the default pi2 app doesn’t scale good on this resolution …
