Grayscale, color fidelity, saturation and gamut to factory settings
Now ASUS can once again show how well they implement their factory calibrations. After all, my colleagues Tim Schiesser (Monitors Unboxed) and Simon Baker (TFTCentral) have certified that the PG32UCDM has an excellent calibration. Or will there be a negative surprise today? After all, you can display the factory certificate via the OSD.
Another gimmick to save paper. Something like this is now available diagonally – sorry, I meant digitally. The monitor here is supposed to have a DeltaE of 0.0? Then let’s measure it…
Color space coverage
There’s something for everyone. From sRGB to DCI-P3 to Adobe RGB, everyone will find what they are looking for – and with sufficient color space coverage.
ASUS PG32UCDM Color Gamut
Gray Scale, Saturation, ColorChecker @ Default Settings (25 % APL)
Here we can already see a considerable difference compared to my two colleagues who have already tested the PG32UCDM. If you take a close look at Tim and Simon’s data, you’ll notice that the RGB balance of my sample has really gone to pot. That alone costs a lot of color accuracy. What’s more, ASUS is now unleashing the monitor on customers in the Rec. 2020 color space. Topic – total oversaturation e.g. with YouTube content etc. Take a look at the measurement results below and we’ll see you again in the interim conclusion…
ASUS PG32UCDM Default Settings
Gray Scale, Saturation, ColorChecker @ OSD sRGB Color Space (25 % APL)
ASUS PG32UCDM OSD Color Space sRGB
Gray Scale, Saturation, ColorChecker @ OSD DCI-P3 Color Space (25 % APL)
ASUS PG32UCDM OSD DCI-P3
Gray Scale, Saturation, ColorChecker @ OSD sRGB Cal Mode (25 % APL)
ASUS PG32UCDM OSD sRGB Cal. Mode
Interim conclusion
I cannot attest to a DeltaE <2 as advertised by ASUS for my sample. Neither in sRGB Cal. mode nor in any other preset. Apparently something went wrong during the calibration in Taiwan, or I’ve hit the jackpot in the panel lottery this time. I suspect that they didn’t take the calibration issue very seriously. Perhaps ASUS also sent my colleagues “golden samples”? I can only speculate at this point. So far (as of week 14) I haven’t received any feedback from ASUS on any of my findings. Anyone who thinks that’s all there is to it is mistaken. As the saying goes, if it goes pear-shaped, it goes with a bang – but more on that later.
Anyone who now thinks that my deviations are due to the fact that I measured with a 25 percent APL is also mistaken. Even if the international standard specifies a 10 percent window, I reserve the right to deviate from it. We remember VW and the diesel emission values on the test bench, everything was ok there. That’s exactly why I measure in different window sizes, to make sure that my results are not a coincidence or were intended by the manufacturer. In this case, the calibration of the RGB balance is simply not correct. The gamma deviations don’t really make the difference here.
The calibration protocol shown at the beginning is nice to look at in digital form, and how do you get a color accuracy with DeltaE 0.0? You could enter it in the OSD using the keyboard. Well, I don’t want to imply anything bad.
