Hello,
I'm setting up my monitor for Rec. 709 calibration and need some advice. My signal chain is:
DeckLink Mini Monitor 4K >> HDMI >> Blackmagic BiDirectional 12G (with 3D LUT) >> HDMI >> Monitor
I'll be using DaVinci Resolve as the TPG. I've read the excellent guides on the Light Illusion website multiple times and find the bold text incredibly helpful for inexperienced calibrators like me. If I may make a small suggestion, including a few more images, screenshots, or examples to complement the detailed instructions could make it easier to understand some of the more complex concepts or quickly locate the mentioned settings.
To help with this discussion, I plan to attach some measurements, including Grey Primary & Secondary Ramp+, using different settings in Resolve (FULL, LEGAL, use SDI 4:4:4), as well as testing both RGB FULL and YCbCr output from the DeckLink. While I consistently achieve dE2000 values below 1 across various combinations, I'm uncertain which configuration is correct.
I've also referred to the excellent Data vs. Legal Levels guide. However, I couldn't quite align the provided explanation with my results, and I'm unsure about the scaling method the BMD 12G Micro Converter requires. I've included attachments showing the decklink, BMD 12G, and Resolve settings I used, along with the measurement results for reference.
I've also included the EDID, though I'm not sure how helpful it is, as it uses a different HDMI signal and is connected directly to the monitor. The only potentially useful information I've been able to gather from the EDID are the R, G, and B coordinates, which I'm using to ensure I select the correct/native picture mode on my monitor to match its native color gamut.
Unfortunately, my monitor doesn't have a specific Legal/Full levels option, so I've adjusted the Black Levels to ensure 16 is the deepest black and 235 is white (clipping anything above 236).
Any clarification on the correct setup or how to determine the appropriate settings would be greatly appreciated. Thank you for your patience and support!

My plan is to also buy an HDfury Vertex/Integral2 in the near future so I can check my signal, but until then, I need to calibrate the monitor.
