Profile test results, maximum brightness and contrast stability
Profile test results, maximum brightness, and contrast stability
After the personal icm profile was downloaded and installed from the manufacturer's website and all monitor settings were reset to default, I ran a test for each of the preset profiles.

ASUS ProArt PA278QV has eight profiles, Standard and sRGB profiles were the most successful, with an average of ΔE*94 of only 1.84-1.31%, which is not a bad indicator for a budget professional monitor. I would also like to note that the obtained values partially corresponded to the data of the passport on the performed factory calibration. In any case, the calibrator is a mandatory accessory for any user who works with color.
The colour coverage of the sRGB space was 98.9% in all profiles, and the colour temperature in sRGB and Standard was very close to the coveted 6500K. As an example, the reality report for an sRGB profile:
Gamma curves are located in a single group and are close to the reference curve, which in principle suggests that some calibration was still performed in the factory. As for the contrast, everything turned out to be fine - 990-1083, which is a little more than the manufacturer said (1000:1). Another pleasant point is the absence of a drop in contrast with increasing brightness.
The maximum brightness was almost 402 cd/m², which is also slightly higher than the stated 350 cd/m². Such brightness is quite enough to work even when direct sunlight hits the matrix.
