Grayscale, color fidelity, saturation and gamut to factory settings
The PG27FFX2A is not entirely convincing in gaming, but what do you get in terms of color accuracy? Let’s look at this in more detail. I’ll say it up front, because I carried out almost all the measurements with the Konica Minolta CA-410 colorimeter. During the test, I dropped the UPRtek MK550T on the floor and unfortunately it has been measuring very inaccurately ever since. However, I was able to reference my ColorChecker Display Plus beforehand. The CA-410 does not need referencing, this colorimeter is based on many filters and is calibrated at the factory. The CA-410 also costs only 10,000 euros – a bargain! If you want to know how accurately the CA-P410 I use can measure, click here! Click here (normal sample penultimate column page 1)
Color space coverage
Gray Scale, Saturation, ColorChecker @ Default Settings (10 % APL)
Gray Scale, Saturation, ColorChecker @ OSD Default Windows Color Space sRGB (10 % APL)
Gray Scale, Saturation, ColorChecker @ OSD Default to DCI-P3 Color Space (10 % APL)
Interim conclusion
As announced, I carried out all the measurements shown above with the CA-410. You will see a measurement comparison between the MK550T and the CA-410 later. Just for your information, most monitor manufacturers use the CA-410 for their calibrations, you only have to look at the calibration protocols.
In addition to 99% sRGB, the PG27FFX2A also offers 95% Adobe RGB and 95% DCI-P3, making this monitor suitable for hobby image editing. If you can cope with the 81 PPI. The monitor cannot deliver in terms of sRGB in the factory state, unless you use the Windows 11 24H2 color management, then the monitor is limited to sRGB (DeltaE < 2) and you can live with that. I think this is completely sufficient for everyday use and gaming.
In detail, the deviation comes from the poor gamma curve and the scattering RGB balance. You can tweak the RGB balance yourself, gamma can only be corrected by software calibration. But that will come later.
