I recently plucked a very inexpensive CG2730 off of that big auction site. Despite 7000 hours on the clock, it buries my LG, 32"/4k, consumer, IPS panel in gamut and black level. Even my wife, who doesn't care too much about color, as long as it is bright enough, sees the difference. Also wild that rRGB and AdobeRGB are presets and can be changed with just a couple button pushes.
Which leads to my question. Since the LUT table is adjusted in the monitor, versus the computer, will I get the same color response from any PC or Mac that it is plugged into, assuming I am looking at the same image?
I now understand why Eizo monitors are are widely used for sensitive imaging. As an aside, I worked in medical research for a long stretch and Eizo monitors were the panels used in radiology, after switching to digital workflows.
I am going to guess that color-managed programs like Photoshop and Lightroom will display the same image, on the same monitor, in the same way - regardless of operating system, as long as the monitor profile is equivalent on both machines.
You might have to calibrate the EIZO on each machine, but as long as you use the EIZO Color Navigator software, you should get identical results.
I have an EIZO CX270 monitor which I use on multiple machines. The ColorNavigator software is installed on only one of them. I calibrate the monitor on that machine using ColorNavigator; as you say, that writes a LUT into the monitor under one of the user slots, but it also creates a .icc file which it saves in its own private database and in ~/Library/ColorSync/Profiles. So the last step you missed is to copy this .icc file to every machine you will connect the monitor to and select that profile.
I last updated ColorNavigator to version 7.1.4, in 2021. The machine it’s on is frozen on an old version of macOS.

Does that mean the same thing (calibration on one machine, like my Windows 10 desktop, will calibrate for other machines, like my Windows 11 laptop, if I copy the profile to the other machines) is true for my BenQ SW 320 which also has a hardware LUT, that I believe their Palette Master Element adjusts?

Thank you good sir. That is the missing piece to the puzzle. It just seemed a little too easy to think I could do one hardware calibration on the monitor only and call it a day. Makes complete sense that a companion .icc profile would have to be copied to each system I might want to use it with. That said, still an incredibly intelligent setup.
The display will load the calibration profile from the color navigator or similar software, or the CG series has the sensor that swings down and can be done automatically. Once the LUT is loaded it will remain and all computers Will look the same until another profile is loaded. For example if one computer has the software and the calibration is good, you can connect any random computer like an uncalibrated work laptop and it will look good assuming that second computer does not load some other profile. I think most people only need ICC profiles on machines that will use a color managed workflow.
