Brightness levels and contrast ratio
We measured 448.5 nits using the screen’s default settings. Also, whites are not stable.
IPS panels are known to have a weakness on blacks. Contrast is 770:1 (below the 1000:1 specs announced with the default preset ) and blacks are 0.59 at 400 nits, which is a poor score. For guidance, an HDR400-certified screen should be below 0.4. But if you turn down the brightness a little, you get decent blacks again.
