Testing HDR LG OLED With Windows Tools at 300,500,900,1200 Nits

So for fun I used Windows HDR Calibration APP on LG OLED Monitor to play with HDR settings in Windows 11

For best quality, you need the latest Windows 10 update and graphics driver, and a VESA DisplayHDR certified HDR monitor.

Tested 300/500/900/1200 Nits and took screen shots of results HDR + WCG Image Viewer.
All images estimated MaxCLL Nits with peak luminance by software

Once the Windows HDR Calibration APP is set then it is good for 95% of the PC Games out there.

Tools used for Test

Windows HDR Calibration APP
HDR + WCG Image Viewer
HDR + Heat Map PC Game The Witcher 3 Next Gen
The Witcher 3 Next Gen for HDR I was changing Paper White settings in dx12user.settings

Brilliant stuff, thanks for posting this, I've been looking for some way to test and measure my HDR profiles, will take a look at this HDR + WCG Image Viewer app!

I wonder do you have any advice / tips about the Windows HDR calibration app? I've been having all sorts of bother with this app, trying to get it to have 2 profiles that get used automatically as they should be across 2 different screens at different times. I've got an unconventional screen setup involving 3 'monitors' - a giant LG OLED C1 in a room downstairs connected to my PC with a 20m fibre optic HDMI 2.1, a 48" Gigabyte Aorus FO48U OLED monitor on desktop along with a dell 24" 'normal' non-HDR monitor on desktop (both these connected to same PC via displayport).

The 'problem' is, the LG C1 has a peak HDR brightness of 800 nits in the app, the FO48U is only 560 nits. So I've created an HDR profile for each of these HDR oled screens, but as one is in another room completely I have one turned off / inactive when the other is on obviously, and vice versa and Windows colour management and the profiles does not seem to be able to cope with this fact....

The way I have my monitors configured (ie #1 + #3 active, #2 off, OR #2 + #3 active, #1 off) plus the fact that Windows display settings ALWAYS names and KEEPS the monitors as fo48u (#1) LG C1 (#2) and Dell24 (#3) yet the windows colour management app always names whichever monitor is the active "primary" as #1 means that it all gets mixed up regarding my HDR profiles! So I either have to have them share one HDR profile (not good obviously), manually switch them every time (ball ache and finicky), or sack them off altogether (but without using an HDR profile the fo48u maxes out at only 446 nits, the LG C1 reports 1499 nits!) Crazy stupid.

So, from my testing my HDR profiles will never work in an AUTOMATIC way with my setup, unless something fundamental changes in windows! Does that make any sense? I wonder if anyone has a similar setup or any tips?

No sorry I do not have a good solution for you.I use display switch between HDR monitors and I have never tried to fix it.
The Windows HDR calibration tool need to be rerun when switching monitors,it is not smart enough to remember profiles.
Might be third party software in the wild that someone made that does this correctly but I have not looked.
