UP2516D, Dual, Daisy Chain, WD15 dock, Precision 5510
- I connected 2x UP2516D monitors in Daisy Chaining (DP cable)
- In a WD15 dock
- Plug into a Precision 5510 laptop
Both of monitors works, but only in "clone" mode (or mirroring mode). How can I split monitors separately?

You are trying to run two UP2516D 2560x1440 60Hz off of the WD15. The problem is that the WD15 only supports two FHD/WUXGA monitors at 1920x1080 60Hz or 1920x1200 60Hz. See the WD15 User's Guide "Display resolution table on page 30.
Back the resolution of both UP2516D to 1920x1080 60Hz. You might then be able to set one as Primary and one as Extended. If you want both to run at 2560x1440 60Hz, you need the TB16 dock.
