Real beginner here, but isn't 'coordination between clients' performed, today, through color profiles straight in the system?

I mean, I have a (hardware) profiler, with which I calibrated each one of my screens, and then by selecting these color profiles, per screen, once and for all* I really see that once activated I do have the same color palette respected when for instance I move a picture window from screen A to screen B...
Which is basically my main need at color management (the next one is having the same profiler calibrate my printers)

I agree color profiles aren't specially HDR, but they still seem to perform a huge task for me, that not any HDR software will do until each one of our screens will self-calibrate...

(*)OK, I'm supposed to recalibrate every now and then, to compensate for ageing

Which color calibration tool do you use?

I have a need for something similar, but there are tons of cheap and not so cheap options out there and I have no idea which would work. I have one HDR monitor, and three non-HDR ones, but really I just want windows to look the same regardless of monitor.

color cal. tool : XRite i1Studio

Hardware side, I have an XRite i1Studio, that can calibrate practically anything (printers, monitors, projectors...). It comes with software for macs, windows and NOT Linux but (a) you can scan and get a profile .icc file with these systems then copy it into Linux and (b) on Linux there are the Argyll package, very efficient if more complicated, that do the job...
Indeed it's extremely significant to move an image from a screen to another and seeing the same colors, and more than that, then switch to any of your printers and still see the same nuances once printed. You just won't regress...
XRite also proposes quite cheaper devices for just screens but I definitely don't regret mine...
