Reasons to switch back to BenQ FastTN?

[j1ffrey]

I have a BenQ XL2546X 240hz sitting in the closet.

I currently use an XG27AQDMG.

I'm wondering if there are any considerable benefits over OLED when swapping back to the BenQ monitor.

Is Dyac2 240hz strobed any better than OLED?

Benefits for input latency?

Anything not typically known?

Is Dyac2 240hz strobed any better than OLED?

Better at what? Eye-tracked motion clarity? Yes.

NOTE: This image above assumes FPS ≥ Hz & https://testufo.com/ghosting#pps=960
A faster UFO / faster-paced game would exacerbate the difference even further.

When comparing total image quality (color representation & pixel density), it's obviously in favour of OLED.

OLED scales like this, when discussing sample & hold mode of operation:


Do note that you need FPS=Hz in all of these scenarios.
Which means you'd need ~2K FPS @ ~2kHz to emulate Zowie's effective motion clarity.

Be mindful that dynamic image quality isn't solely comprised of eye-tracked (effective) motion clarity alone.

Thank you for the response.

I definitely care more about motion clarity than overall image quality because I play Deadlock.

One thing I have never understood clearly is the apparent strict necessity for fps=hz when strobing. Does this need to be the case? And for what purpose?

What happens when fps =/= hz both lesser and greater when strobing?

I have always been under the impression that strobing without insanely overkill hardware was a sinking ship bc fps lower than hz means you don't get the benefits of strobing, but I'm not exactly aware of what happens.

The left side: impulse mode (backlight strobing) enabled, when FPS<Hz (namely, FPS = Hz / 2)
The right side: sample & hold (non-strobed) mode, when FPS<Hz (at specific pixel speed)

You are trading the aliasing-like effect (caused by fps/hz mismatch) for sample & hold blur (which gets blurrier as you lower FPS)
The actual effective motion clarity (pulse on interval of specific implementation) stays the same. Meaning, the sharpness is the same, you just get a distorted image.
This occurred doing CRT era as well.

I see

I actually read almost entirely into the "Quest for 1000hz" thing on blur busters main, and I'm surprised by the findings that double images occur bc I think what I remember of my experience strobing and fps<hz didn't seem like any significant image or motion glitches happened, but I also could not have been paying attention closely.

Overall, if I am chasing motion clarity above all, do you think the switch from an XG27AQDMG to an XL2546X and using strobing is a worthy enough swap for the sake of motion clarity? Or is OLED sample and hold not worse enough to justify the swap in your opinion (if you happen to have one)?

Assuming 240hz OLED unstrobed vs 240hz BenQ FastTN strobed

I have since swapped monitors.

I do like the strobing and I also interestingly prefer the size of the panel. Also I might be crazy but it FEELS like this panel has a higher resolution quality, and I think it might be related to the pixel density of 1080p on 24in vs 1440p on 27?

Anyway, in the image referenced above, do you happen to know where it comes from and possibly what settings are used on that XL2546X to achieve that result? My ufo test looks slightly similar but that one looks fantastic and I want that one if I can get it.

All UFOs shots you see are heavily dependant on the pixel speed they're photographed in.
MUB uses 960 px/s for all of his UFOs.
The lowest pulse width mode on the XL2546X is the highest refresh rate setting (240Hz) & DyAc2=Premium

27" QHD has a higher pixel density than 24" FHD.
What you're perceiving as "sharper" is the fact that your effective motion clarity isnt 240-360Hz anymore, but "+2000Hz" (due to backlight strobing)
Or to word it differently – your temporal resolution is higher.

all at 500hz, not much if any difference when 540hz or 610hz

asus newer model has worse strobing than its predecessor, on on its highest level 5 clarity, is dimmer than zowie xl2586x, and worse

after looking back, not the clearest image, but in person, the asus looks a bit clearer than the zowie, but the double imaging is worse

What about AMA? I currently use high bc I think it has less overshoot than premium. I also have a custom setting for AMA which is a slider from 0-30.

Also is there a way to change the position of the "crosstalk band" I think it's called? I did that with the strobe utility on my old XL2546 but last I remember trying the strobe utility didn't work with X model.
