Pixel response times vs. overshoot @ max. refresh rate
BenQ has its own naming convention for pixel overdrive. AMA = Advanced Motion Acceleration. Sounds strange – but it’s true! Fact: The TN panel of the XL2566K is without a doubt the fastest LCD panel I’ve tested so far. Here, the TN panel can fully show its strength. But is that enough for 360 Hz, and what about response times and overshoot at 144 Hz? Can the monitor deliver?
Response Times @ 360 Hz
Overshoot @ 360 Hz
With AMA disabled, the pixel response time is just too slow for 360 Hz and that leads to ghosting. With AMA High it looks better. AMA Premium is pretty fast with 1.5 ms on average. Overshoot is not an issue at 360 Hz, because you don’t notice it at 2.7 ms display time. But look how it looks at 60 Hz.
Still, AMA Premium is recommendable from my point of view, as long as you play at 360 FPS and above. Which should not be a problem in Valorant or CS:GO in 1080p. Below 360 Hz or for VRR gaming I recommend AMA High.
Variable Overdrive or single Overdrive Experiance?
One or the other has probably already recognized it. Variable Overdrive is unfortunately not offered by the XL2566K in AMA Premium Overdrive. Otherwise the result with AMA Premium @ 60 Hz would not have been so dramatic. But what the AMA High Overdrive offers, that we now take a close look.
Response Times @ 360 – 60 Hz
Overshoot @ 360 – 60 Hz
From my point of view, the BenQ ZOWIE offers a Variable Overdrive in AMA High mode and thus creates the basis for VRR gaming. After all, the response times increase with falling frame rates to minimize or prevent overshoot. Whether BenQ intended this or not, remains to be seen. My colleague Tim from Hardware Unboxed comes to a different conclusion. According to his measurements (note that Tim has different measurement equipment), the XL2566K can only deliver a single overdrive experience.
At the end of the day, however, that doesn’t make a difference as long as overshoot doesn’t become problematic under any circumstances. AMD-FreeSync and NVIDIA G-Sync can be supported by the XL2566K – if the customer wants it. It’s just a question of whether you want to use DyAc or not? But more about that later.
