Hey everyone,
Monitor calibration is still a big question mark in my head while reading all of Mixinglight articles.

I hope this question is simple and easy to answer for most of you.

When working on a color managed project and I want to create deliverables in Rec709, P3, and HDR, I'm trying to figure out whether I'll need to change my calibration LUT for each of my monitors.
I'm planing on getting an SDI to HDMI 6G converter to be able to load my calibration LUT to the hardware as my monitor (asus proart) doesn't support LUTs.
If I calibrate my monitor for Rec709 Gamma2.4 100nits, and then switch my project to P3 for the trim pass, will I need to load a new calibration LUT to my hardware? Is there perhaps a more elegant way vs doing it manually for each monitor?
Do you guys have multiple calibration LUTs on standby for each monitor?

Btw. Hardware configuration is:
iMac -> Thunderbolt to Ultra Studio 4K Mini
1. HDMI to LG CX Oled Series (LUT loaded directly to TV)
2. SDI to HDMI 6G Converter with hardware LUT -> Asus ProArt

Generally, the white balance will overlap though at near peak brightness in HDR, it may be off compared to SDR.
Most if not all monitors have a form of auto-brightness adjustment when you are near peak brightness.

I personally do not like LUTs for calibration, though many colorists swear by it.

How would you calibrate your monitors that don't have full on hardware controls such as Flenders?
I measured the Asus ProArt and the color accuracy is pretty damn good for the price and it supports DolbyVision and HDR (probably more on the entry level side), the controls however are not broadcast level and rather clunky

Not an expert at all, but you should have each mode calibrated separately for sure.
Those monitors most likely won't hit 100% P3.

Good point, though I have not used a monitor without hardware controls.

Hardware calibration is also LUT based, no?
Difference is where this LUT lives- on machine side (GPU), actual software (eg. Resolve), 3rd party box in the chain (LUT boxes) or inside monitor itself (then you can do so called 'hardware calibration' as it affects monitor internals).
Hardware calibration should be the most accurate as it affects monitor engine itself, but it can be done only on monitors which support it.

The Asus ProArt PA32UCX does support some sort of hardware calibration however, in my experience it's garbage. The software, at least on Mac, keeps freezing no matter what machine I tried it with and the newest software interface is not available for Mac. So in theory it can, in practice it can't.
Btw. if anyone here has experience with the ProArt and got their Software to work, I'll postmate you a case of beer
So in that case it looks like a 3rd party LUT box would be my next best option. But in any case, in my (unexperienced) mind, I'd think although the whitepoint is dialed in, the colors shift once the peak brightness changes (i.e. from SDR to HDR) especially in this category of monitors?! Not sure if any monitor can hold up switching from 100nits to 1000nits without a slight color shift...

I think the same- no chance it will hold up.
In studios even with top displays each mode has always own calibrated preset (quite often even if only difference is just a gamma change).

This seems to be the problem with most of those mid range displays. Just not there yet.
