Dreamcolor with Decklink Studio

Hey guys,

I have a brand new HP Dreamcolor Z27x, attached to my Decklink 4k Studio via HDMI Cable.
Dreamcolor is set to Rec 709, Video Levels - Decklink is set to YUV (does not make a real difference if it set to RGB).

My Problem is: I know, this HP pre-Calibration may be not the masterpiece but my Pictures looks so different from all other displays(PC Gui, 4k Consumer Panel, Viewfinder of my CAM).
It's desaturated and little bit to dark purely subjectiv.

So my Question: Is this right this way and all my other displays look wrong or ist there someting wrong with my dreamcolor?!

Very possible it shows you how wrong other displays are
Do you have whole project set to Rec.709? Does black level look ok?

Hey Andrew,

yes, its within Premiere - so there are no other colorspaces avaiable .

Black level looks good while playing. If I see my Colorbars with my three black stripes its look a little bit to dark (but really only a little bit.)

Try it from Resolve.
Premiere should be fine for Rec.709 masters, but other than this there is really no color management there.
You can also try playing same file from MediaExpress, just to see if you get same result as from Premiere. There may be bugs in Premiere- its integration with BM hardware is not that perfect at all.
