Pixel response times vs. overshoot @ 60 Hz refresh rate
Even though the PA27JCV is not a gaming monitor, I won’t miss the opportunity to measure the pixel response times in connection with possible overshoot. ASUS has “hidden” six different overdrive settings (called Trace Free) in the OSD menu. Hidden because you can only set them if you switch off Adaptive-Sync (Media-Sync). Extremely annoying! This means: Adaptive-Sync off, then set Overdrive, then switch Adaptive-Sync on again. This is a real joy when measuring. Fortunately, the PA27JCV can only handle 60 Hz, otherwise I would probably still be measuring today. Note: I have deactivated local dimming
Trace Free 0
Trace Free 20
Trace Free 40
Trace Free 60
Trace Free 80
Trace Free 100
The built-in IPS panel is not one of the fastest on the market, even a blind person can see that – if they look closely. I can’t recommend the Trace Free Zero and 20 overdrive settings, as the panel is quite sluggish here. Trace Free 40 is basically the best the PA27JCV has to offer. The Trace Free 60 factory setting is also acceptable. The last two settings, Trace Free 80 and 100, produce really bad inverse ghosting, which I can only advise against. At least the monitor achieves the 5 ms response time that ASUS advertises if you opt for the Trace Free 100 overdrive. The fact that this is unusable in terms of overshoot is another matter. Fortunately, the PA27JCV is not made for real fast shooter gaming either, which would no longer be up to date at only 60 Hz (in my opinion).
If you’re wondering what the whole thing looks like with dimming activated:
The response times with regard to white (255) become extremely slower and the overshoot increases slightly. Therefore, every buyer should take the trouble to set the overdrive with Dimming on via UFO Ghosting Test. Personally, I get on very well with Trace Free 60 (with and without dimming). But if in doubt, Trace Free 40 will definitely work.
