HDR performance
In my opinion, the PA27JCV is not a true HDR monitor, as edge-lit dimming has too many drawbacks. Yes, the general contrast is significantly better, but that’s not really enough for true HDR. The maximum peak brightness of just over 600 nits is also no revelation. After all, the 600 nits are also available with a 100 percent APL. But first take a look at the measured values.
HDR PQ Base
HDR PQ Optimized
HDR PQ Clip (Dimming on vs. off)
Interim conclusion
Depending on the mode, different levels of color accuracy can be achieved. The ColorMatch HDR accuracy I measured in HDR Clip mode is the best I’ve seen so far. In my opinion, the HDR clip mode with or without dimming is the best in terms of EOTF tracking. If you want an earlier rolloff, then I recommend the HDR Optimized mode.
The PA27JCV’s weaknesses are revealed in the black levels (the lower part of the EOTF), where you can see that the monitor cannot deliver true black like an OLED in very dark scenes. The longitudinal stripes caused by the edge-lit dimming (16 zones) are also noticeable at all times.
Why ASUS has not installed a mini-LED panel with full array local dimming at the price – which is the basis here – is beyond me. I call the HDR experience lower entry-level: The PA27JCV has always tried to meet the HDR requirements.
