Color Page showing washed out blacks w Decklink 4k

Using Resolve 15b5 in Windows. Just installed a Decklink 4k mini monitor card. Colors look good in the edit page, but when switching to the color page, my blacks are washed out. My settings are the same as they have always been... i.e:

Color Science = DaVinci YRHB Color Managed
Input Color Space = Bypass
Timeline Color Space = Rec.709 Gamma 2.2
Output COlor Space = Rec.709 Gamma 2.2

Any ideas? Im not sure what else to try.

Could be the GUI bug with LUTs:
Switch the viewer LUTs to 'None' and check if they change when you try different LUTs on the output. If this happens, this is a well documented error and should be known to the dev team.

Booted up the computer this morning and now the black levels have returned to normal. So I don't know how to reproduce it either. If it happens again Ill try to figure it out.
