You need a good display and proper calibration. Until there we agree. There is no need for this calibration to happen in the panel itself and there is no need for a dedicated BM GPU. It's just an easy way for people on Mac OS to bypass Apples color management madness.
On Windows there is nothing you need to bypass. There is no system wide color thing. Each app does it's own color management.
All that Windows provides is an optional API to query a display profile for a display if one was assigned. Optionally this could then be used by the app to do its own color management.
Neither Resolve nor any video player uses that. They want 3D LUTs you explicitly need to create with something like DisplayCal and a measurement probe.
Create a display LUT for Resolve and for your player (I'd recommend MadVR) and verify that it is correct using your preferred probe and management system (I use DisplayCal).
HDR is a different story. That's probably where I'd agree an getting a Decklink card, also things like NobeDisplay exist.
And yes, using VLC is a bad idea. It doesn't have any color management. No idea why people here use it so much. It's nuts to use it to judge colors on Windows (no idea what does on Mac).
MPC-BE + MadVR + 3D Calibration LUT is an accurate choice. Many others exit.
