I wanted to be clear on this question, if I have an RGB 444 Dual Link connection with two SDI cables to the monitor, would that affect/alter the color from the source footage of ProRes 422 Quicktimes (or any other footage that is 422 for that matter)? As opposed to using the YUV 422 SDI option under Video Monitoring.

The monitor displays RGB. Any 422 source is converted to RGB by Resolve before image processing. At the monitoring stage, you can send 422 single link from Resolve to your monitor, which will then matrix it to RGB, or you can send dual link 444 from Resolve to your monitor which will display the RGB.

So, every source ultimately becomes RGB before the monitor can display it. If you have the ability to use dual link RGB from Resolve, I would use that.

I have not included discussion about full (data) vs video levels here as most users will be in legal video range in their monitoring.
