Color performance after a full software calibration
The first thing I’m going to do is put my hand on the sRGB mode, as there’s certainly room for improvement – without calibrating. I then apply a software calibration to the OSD standard mode, so that all color spaces can be used in the best possible way.
OSD Setting D65 @ 160 Nits and CCT corrected sRGB Mode
I was able to improve a lot with these settings. White point and RGB balance see PDF below.
Now all DeltaE values are well below two, so even amateur photo editors should be happy. If not, then you will have to do a software calibration and it will look like this.
OSD Setting D65 @ 200 Nits
Basis for the software calibration: Preset Standard –> Custom Color Temperature and then apply the brightness values and the RGB settings. This gives you a significantly better RGB balance and a white point of 6521 Kelvin.
OSD Standard Mode – Full calibration with Portrait Displays Calman Ultimate
If you have the appropriate hardware and software, you should be able to achieve similar values. Always remember that ICC profiles are not supported by all applications.
Spectral distribution and “Eye-Safe”
The QD-OLED panel of the 34WQHD240-C also looks the same in the spectral analysis as all other QD-OLEDs before it.
Spectral distribution @ D65, 200 Nits (100 % White Window)
The peak here is at 638 nm – i.e. in the red light spectrum. In terms of eye-safe, the blue light component in the peak is around 455 nm. Unfortunately, I cannot say with certainty to what extent this can already be described as eye-safe.
Uniformity
The image uniformity is always a pleasure with a QD OLED panel. No dirty screen effect and outstanding viewing angle stability.
Image errors and other issues
In terms of text readability, the Corsair Xeneon 34WQHD240-C is no different from the other 34″ QD-OLED monitors. It still uses the same subpixel layout as the Samsung Odyssey OLED G8 (34″). I don’t have any problems with this, but there are said to be people who notice text fringing. I didn’t notice any problems with AMD or NVIDIA graphics cards. I can’t test consoles. VRR flicker can occur with OLED, which usually occurs with strong frame fluctuations or in game menus. A frame limiter always helps here!
With the old V100 firmware, I once had the problem that the monitor simply switched off. I suspect that it wanted to perform some kind of pixel refresh. That was pretty annoying as I was just about to take my measurements. I find switching off without any indication pretty uncool. Furthermore, the sRGB mode was unusable with the V100, as the Sharpness function in the OSD was set to zero and grayed out at the same time. The picture was correspondingly blurred – hence my urgent advice: Update to firmware V103! With the new firmware, you can set the sharpness to seven and then it will work.
Sound reproduction
The Corsair Xenoen 34WQHD240-C does not have speakers. Sound via the built-in audio connections works without any problems.
