I have used Datacolor Spyder X for the past year. I think there are so many variables for synchronizing a monitor to a PC it is tough and nearly impossible even for the best tools or programs.

After a bit of logic I decided to try something different and maybe simple.

I held a large grey card next to my monitor for the first time. The day was especially overcast and dark plus the room lighting was a factor. The match was not even close. But I used the best calibration tool available... hmmm

To the chase...

Go to Photoshop and create a 4000 x 6000 pxl adjustment layer. Then fill the layer with 50% grey and save it as a Jpeg. Also kept the layer from Photoshop open on the monitor.

Next, open the grey jpeg layer just created on your Mac or pc. Now you can see the same 50% grey image displayed on both screens. You will most likely see two different shades of Grey like I did... and a different shade than the gold standard physical grey card you have in your hand making it three...

Do this... manually adjust the monitor color to the physical grey card. Next adjusted the Mac or pc with its custom color adjustment to the physical card and adjusted monitor. All will now match perfectly and you will be able to adjust easily for the effects of ambient and room light at any time.

The most important point is you can get perfect white balance between the two screens with out buying expensive calibration gear that doesn't work.

If someone says their fancy calibrator gizmo does work, then try comparing your physical grey card to you calibrated screen, you may be amazed...

I verified the results on another pc, a tablet and my Samsumg fold for comparison under the same ambient and in the same room lighting. I also re edited another layer and checked it with the eye dropper in Photoshop and it was perfect...

Oh, and all of those pre programed white balance options like I have on my Macbook Pro M2Max are useless...

Most AF systems do benefit from settings changes for specific subject matter. There are probably some videos on YouTube for every brand and model, suggesting settings for particular subjects.

Sean Robinson of Panasonic recently did a Lumix Live podcast on the hybrid PDAF systems in the new S5 II, S5 IIX, and G9 II bodies. He does a lot of motorcycle racing photography, so he has identified particular combinations of settings that work for that, and others that work for portraits, sports action, still life, landscape, birds in flight, animals in brush, etc.

I'm pretty sure there are videos by Nikon, Canon, Sony, Fujifilm, and Olympus experts who have refined their settings for specific purposes.

Using any camera "out of the box" is likely to be hit or miss, depending upon the subject matter.
