I've had this monitor (LG 45" GX9 (45GX950A) for a bit and there is one point of confusion that I'm hoping can be cleared up. I get conflicting instructions on the proper way to "calibrate" hdr in both W11 HDR Calibration Tool and Peak Brightness in-game.

Some people say you need to put both Peak and 100% to 1300 nits, some say put the peak to 770'ish (10% peak) and 270'ish (100% sustained), and some have told me do 600 nits for both due to the way the monitor does Tone Mapping.

Can anyone tell me the proper way to go about it on this monitor? To be clear I mean both the calibration tool and in-game peak brightnesses. This is assuming the Peak Brightness is set to HIGH on the monitor.
