Color performance after a full software calibration
The first thing I’m going to do now is tweak the RGB settings and try to improve the RGB balance. I did this right at the beginning with the UPRtek MK550T to see where the journey would take me, of course I photographed the values and then did an OSD reset. Then came the accident of horror and the MK550T no longer wanted to measure accurately. This is where the CA-410 from Konica Minolta comes into play. But first things first.
OSD Setting D65 @ 200 Nits
You remain in OSD Standard mode and set the brightness to level 55 and set the color temperature to User. You then only have to set the user as shown in the picture. You can see how this affects the color accuracy in the measurement logs.
CCT Corrected OSD Standard – Windows sRGB Mode
CCT Corrected OSD Standard – DCI-P3
As you can see, the MK550T (which I used to set the RGB balance) and CA-410 measure almost the same in terms of gray scale. The deviations are within the measurement tolerance. The color accuracy can be slightly improved with the RGB correction. The gamma curve remains problematic and there is no getting around an ICC profile.
Full calibration with Portrait Displays Calman Ultimate
After the calibration, basically only the 100 percent values for P3 and Adobe RGB with high deviations remain. This is only due to the panel itself, as the maximum gamut is not sufficient. However, this should be sufficient for fast semi-professional image processing in case of doubt. After all, the PG27FFX2A is a pure gaming monitor.
Spectral distribution and “Eye-Safe”
Based on the spectral analysis, I assume that the IPS panel is supplied by BOE or HKC.
Spectral distribution @ D65, 200 Nits (100 % White Window)
The peak here is at 633 nm – i.e. in the red light spectrum. In terms of eye-safe, the blue light component in the peak is around 461 nm. Unfortunately, I cannot say with certainty to what extent this can already be described as eye-safe. If necessary, the blue light component can be reduced in the OSD, but be careful, this is at the expense of color accuracy.
Uniformity
The picture uniformity is basically ok if you mainly use the monitor for gaming. The panel shows slight weaknesses on the right edge. Glowing or bleeding is also limited here – but this can vary from panel to panel – typical IPS.
Image errors and other issues
Apart from the weaknesses I pointed out in this article – I could not find any other problems.
Sound reproduction
The built-in speakers (2x 2 watts) sound more like a tin can than real gaming sound. The sound via 3.5 mm also works.
Webcam and microphone
Are not installed. This brings us to the topic of HDR.
