I certainly did read all of that before I started. It didn't specify how to adjust the brightness so that was why I searched how. The video I watched started with Windows 11 and that was why I mentioned it, but I also mentioned that you couldn't adjust brightness from there, only kelvin. I did adjust the brightness through the monitor before the first calibration attempt and it didn't match my prints. So, I followed your troubleshooting steps and it still wasn't coming right.
Do the "brightness" settings on window 11 not affect the outcome at all? I would assume that anything able to alter your colors on the screen would affect it, but I don't know, that is why I am asking. The only I did through Windows 11 was turn the "night light" strength down to 0% which is 6500k. Same goes for the graphics card, do it's settings not matter? Am I just making this more complicated for myself than it needs to be?
After I did a factory reset on my monitor, did the first recalibration following the directions, and the troubleshooting, the prints were still darker, greener, and less vibrant. I have at this point messed with too many settings so my plan is to factory reset my monitor again and factory reset my graphics card, then try again from the beginning. If things are working after that first attempt, or your troubleshooting directions, then I will add an update here and ask for advice before messing too much with settings.
