Hi,
Sorry, I am just a total beginner, so maybe I don't understand something basic. So, I have ZRO and a monitor connected via Decklink in DaVinci Resolve. I have succesfully connected my probe (i1D3) and ZRO with DaVinci Resolve, the colour patches are displayed on this target monitor. Then traying to follow the instruction referring manual correction I tried to enable Test Patterns (f.i. Contrast), but these patterns are only visible on my GUI monitor, on the target one. If it matters, the ZRO is installed on the same PC as DaVinci Resolve. Should I maybe switch some setting or so...?

As per the user guides, test patterns from within the ColourSpace floating patch window are local only.
You need to load the same/similar patterns on the Resolve time line.
Same with any external TPG.
If you think about it, it is logical that the internal patterns cannot be displayed via an external TPG...

Resolve iTPG can generate patches from ColourSpace, but it can't generate patterns.

The patterns of ColourSpace iTPG can only be generated from the ColourSpace pattern window, not from any other external TPG/iTPG.

You can import Ted's Media Files into a Resolve timeline if you use a video range signal output for your reference monitor.
