Hey there,
im using currently a XL2540 as my main gaming display. How much of a difference will the jump to the XG2431 make? Thinking of ordering once it hits European store shelfs.
On a side note: Since the first batch of proper OLED gaming monitors is slowly arriving, how does the motion claritiy of the AW3423DW stack up against the XG2431? Sorry if this question seems illegitimate, I'm just wondering since OLED pixel response times are a magnitue lower than even TN panels
There are two different pixel response benchmarks, GtG and MPRT, as seen in
Pixel Response FAQ; GtG Versus MPRT.
GtG’s on OLEDs is lower, but MPRTs of strobed LCDs (e.g. PureXP=ON) is lower than any of the OLEDs, whether be Rift, or LG OLED, or the new gaming monitors.
For non-strobed, OLED is superior. But for strobed, good LCDs like XG2431 still can do MPRTs better than than even the best strobed OLEDs.
Once GtG reaches near 0, there is still motion blur from display persistence (Aka pixel visibility time):

Shortening pixel visibility time requires shortening refresh cycles, either via higher Hz or via briefer flash of Hz. For nonstrobed, double frame rate at double Hz will halve motion blur. But likewise, halving frame flash time (via a strobe backlight instead) halves motion blur without need to raise Hz or framerate. It’s also why 120fps 120Hz strobed has less motion blur than 240Hz non-strobed, too.
Eventually over the longer term, OLED may produce superior MPRTs, but Talbot-Plateau’s Law means it’s a little easier to outsource extra brightness in a strobed backlight than strobing OLED pixels directly. Turning 4ms MPRT into, say, 0.4ms MPRT (PureXP Ultra on XG2431 at 240Hz) requires 10x the brightness to maintain refresh rate, for framerate=Hz=stroberate. That’s kind of hard to do with brightness-limited OLEDs, so OLED MPRTs cant reach sub-millisecond levels like BenQ’s and ViewSonic’s can.
However, Hz for Hz, in non-strobed operation, OLEDs will always look clearer for motion. For example, 120Hz nonstrobed OLED looks better than 120Hz nonstrobed TN. This is because in an equal-MPRT-bottleneck situation (1/120sec), GtG pixel response takes over as the determinant factor.
It’s imply the fact that LCDs can strobe more brightly briefer, LCDs with good strobe tuning can get more CRT-motion-clarity than OLEDs can at this time. Especially when calibrated with large vertical totals to hide LCD GtG 100% hidden by human eyes between refresh cycles — for zero-crosstalk operation. XG2431 can go as zero-crosstalk as an Oculus Quest 2 VR LCD, with the right calibration instructions at
