Blur Busters Forums

Rtings confirm can't single strobe under 100Hz, no motion blur reduction for 60FPS capped games Disabled willfully by firmware, because technically can be done, and leave user the decission:

* Single strobe with flicker (like old CRT monitors)
* Double strobe without flicker, but unvearable double image
* Strobe Off with tons of motion blur

All three have cons, but BenQ decides the first option is not valid. Players than prioritize remove motion blur do not agree

See here the amazing motion handling, from smoothness viewpoint, of XL2540 240Hz hacked to run VSync 60FPS with 60Hz single strobe, fullscreen 100% free of crosstalk ! Ufo focus is perfect, like in static image ! https://forums.blurbusters.com/viewtopi ... =13&t=7520

The dream comes true, only at 60Hz for now, current LCD pixel speed not allow do it at more frequency 100% clear.

XL2546K total response time with AMA Off, without artifacts, raw panel speed, is far from 240Hz 4.16ms refresh cicle. Only under 4.16 with 1.2-1.8 range when go to black, all others GtG are betwhen 4.9-16. From 2 to 4 refresh cicles to reach color target. Not as fast as we would like. Sadly overdrive not solve this, the maximun GtG is even higher, High 3.5-16.8, Premium 5.1-16.9

But with panel running internaly at 240Hz outputting single strobing 60Hz, with VT tweaks, refresh cicle is 16.6ms, and GtG times are the same of 240Hz. So all total GtG times are inside refresh cicle, 60Hz single strobe DyAc+ is ready to do fullscreen crosstalk free without overdrive artifacts.

Rtings only show DyAc+ pursuit image at 240Hz, to much crosstalk. Anyone has tested 100 and 120Hz with AMA Off DyAc+ Premium ? In teory seeing the pixel speed, can't be fully clear like 60, but should be decent, maybe 2/3 screen crosstalk free ? One pursuit video would be greatly appreciated, to see what crosstalk base there are, to apply emulator software BFI like RetroArch 120Hz hardware single strobe converted to 60Hz single strobe with 2:1 ratio, much less crosstalk than 240 to 60 with 4:1

Would you give slighly edge for XL2546K then VG259QM when it comes to fast pace competive shooters (like Valorant and CS:GO) in terms of motion and responsiveness?

Yes.

RTings tested with AMA Off and probably Dyac Premium(they did not specify which dyac they used but since they said that AMA Off is the best I think they tested with AMA Off which produces a lot of crosstalk).

I'm going to show you some pictures:

240hz AMA OFF, Dyac Premium ↴




240hz AMA Premium, Dyac Premium ↴




As you can see AMA Off has two ghosty friends behind the main one, the first one is noitceable and the other is feint.
AMA Premium however has just one ghosty image behind which is visible only because of overshoot in some specific transitions.

I consider this more than acceptable for competitive games at 240hz, is it 100% crosstalk free? Not exactly but this is much better than the VG259QM's ELMB that they rated 8.0 (with stuck overdrive, and a shorter strobe phase with a slower G2G panel [which is a really dumb approach to strobing on IPS]), the Benq'd Dyac was rated 7.3 )

I'm actually surprised at the quality pictures I'm getting out of my OP6 camera , I'm recording at 4k 60fps, unfortunately I don't have a slider so everything is done manually and that's why some tests are slightly tilted to the left/right

On a side note, as already stated by @speancer , this panel doesn't suffer from the Pixel inversion/vertical lines issue that plague many 240hz TNs.

I'm really confused after rtings review. I prefer to use 240hz panels in default ovedrive mode and use my VG279QM with OD60 and 240hz, according to rtings vg279qm review total response time in this case 5.8ms, but 2546k has 7.6ms, does it mean that TN 240hz panel more blurry than 240hz IPS panel? I would like to change my VG279QM to 2546k cause of better motion clarity and already ordered 2546k in shop, but idk now take it or cancel my order. Axaro1 could you tell, does 2546k has better motion clarity in stock mode than stock vg259qm ? I don't believe that 7.6ms it's true, because I saw CS GO on Acer XF252QX and expected to see the same with 2546K

I guess you are one of those guys who are extremely sensible to overshoot (in my case I'm much more sensible to ghosting, motion perception is a very subjective topic), to be honest I'm fine having to deal with some overshoot if it means that there are noticeable improvements in motion clarity, as long as I don't notice any overshoot while playing I consider an overdrive to be usable.
The benq doesn't have enough overdrive granularity for people who are sensible to those kinds of artifacts and it comes with just 3 AMA settings, AMA Off is imo unusable, AMA High is the sweet spot for non strobed mode and AMA Premium is the sweet spot for Dyac.

In stock mode it comes with AMA High, which is imo a good example of overshoot/G2G balance and it's perfectly tuned for competitive gaming but if you can't stand any amount of overshoot you'll be stuck with AMA Off which from my experience can be compared to OD20 on the VG259QM.
It means that no voltage is applied on the panel so AMA off is just the raw panel with no tuning.

OD60 on the VG259QM (which is the stock overdrive for the 24.5") has better motion clarity than the XL2546K with AMA Off so I don't recommend you to get the Zowie if you can't even handle OD80 on the VG279QM which comes with 3.9% overshoot.

AMA High can be compared to OD120 on the VG259QM in terms of overshoot (and to OD80 in terms of G2G) but I noticed that if I increase the ufotest speed to something like 2400 pixels per seconds the TN panel does a better job dissipating the overshoot trail which seems to be shorter even though on paper the amount of overshoot is considerably higher on the TN.

The total response time is faster on the Asus but if G2G is faster on the Benq it means that the two panels could be equally at the same color target after 4.16ms from the beginning of the transition but you have spent more time watching a pixel transition on the Asus compared to the Benq which will result in better motion clarity on the TN since you have more headroom in each refresh to see exactly what the target transition is.

Thank you. Really strange, how come that new TN 240hz panel slower than IPS 240hz in default mode. Perhaps, I will cancel my order then. I'm sorry, one more question, AMA OFF is default setting as I understood?

AMA High is default, if the store where you bought the monitor has a good return policy you might want to give the Benq before cancelling the order.

I really want to compare new 240hz IPS panel with TN and thinking about it to just give a try, then return xl2546k to the shop in case of dissatisfaction. Anyway thanks for the info! )

If you plan to test it, it will be awesome to hear your thoughts on how these two monitors compare. So far it seems like axaro1 is the only one with the both of them, so it will be nice to hear another user's point of view.

EDIT: Also, it seems like other people report that the XL2546K has been nothing short of an upgrade over the Asus (from the reddit thread I mentioned yesterday), so IMHO, you should definitely not cancel your order and give it a try.

The review has been released:

Interesting that they didn't have the same issue with g-sync that I had (see my first post). Of course I don't know how extensive their testing of VRR is. They do note that g-sync does not work on HDMI, though I still haven't tested that myself .

Here's a person that had the same issue as me, over on reddit with a video (I already copy pasted my solution):
https://www.reddit.com/r/Zowie/comments ... c_enabled/ (I'd post the proper link, but I'm not allowed to post links apparently )

Shame that Nvidia hasn't certified this monitor (yet). That way we wouldn't need CRU to set the range for Nvidia cards.
