HDR performance
HDR is no real challenge for the Corsair Xeneon 34WQHD240-C. Thanks to the QD-OLED panel, the only question that remains is: How exactly can the monitor display HDR and does the graphics card play a role in this? The graphics card doesn’t play a role, the measured values look comparable for NVIDIA or AMD. Corsair also only offers two HDR options:
HDR True Black 400
Peak Brightness 1000 Nits
Interim conclusion HDR
The True Black 400 mode is very good in terms of EOTF tracking, hence the very good color accuracy. If you switch to Peak Brightness mode in the OSD, the panel achieves 1000 nits, but we see the familiar panel dimming with large-area HDR content. All QD OLEDs have this problem – including the Samsung itself. The larger the APL, the worse the EOTF tracking – the roll-off comes much too early. This results in a loss of brightness and the color accuracy also deviates significantly.
