Awesome! Let us know how you end up liking the monitor. Would you not recommend the XL2546k for someone that already owns the Acer 390hz? I main PUBG right now and I never reach 390 fps in this game. I really wanted to try the Benq but idk if it’s a smart move for what it cost.
Sure! I don't play PUBG but I will share my experience with some other games and make a proper comparison.

I will also see how it performs with my Viper 8khz.

Optimum tech ufotests are the only things making me worried about the XV252QF but his XL2546K ufotest also looks completely different from my pfp (same speed, same monitor, same settings) so idk if I should trust it.

Every other ufotests I've seen was great (from people in this thread + other reviewers).

Optimum Tech takes only the top row ufo with dark cyan background where lcds always have slower transitions. It's best to capture all three rows. In addition to that his camera settings or filters are a bit weird. He managed to make it look over and underexposed at the same time. Bijan Jamshidi did a good job capturing all 360Hz models and Zowie vs Acer at 1920 pps. Check 1st page.

XL is definitely sharper, not sure about crosstalk since noone talked about it yet. 390 or 360 Hz is a bit much for this IPS, meaning there is some smearing in both strobed and non-strobed situations. 240Hz strobing will look clearer but less sharp, plus u could probably do some qft at 240. Acer is missing one more VRB level with shorter pulse duration that gets the motion sharper (~150 nits). Now it looks to be around 40% on, 60% off duty cycle for VRB Extreme. Acer has less aggressive overshoot than Zowie.

Nothing is as sharp as the 2546K but I expect it to be less blurry than my VG259QM and having less artifacts than 280hz ELMB.

The Benq was great in terms of motion clarity but sometimes in games like Apex color accuracy was blending enemies with the background and at times it felt sluggish in games like Overwatch compared to the VG259QM.

The only two things that I miss about the 2546K are overall clarity and a sharpness slider, I don't expect sharpness on the XV252QM to be worse than Asus vividpixel implementation, which consistently caused sharpness clipping due to bad convolution offsets/shiftings that was exacerbated by low response times.

I don't think that 75+% duty cycle is something that has a reason to be achieved when the panel is not using an overvolted backlight (unless people play in a very dark room at night, and even then I'd argue that such low brightness is not enough, I personally wouldn't go lower than 200 nits regardless of how much dark a room is), let's see RTings BFI chart results, 60% seems in line with the ufotest and 240 nits strobing results with this panel.

Seems like something that can be mitigated by Black Boost, kind of like OD120 with Shadow Boost improving overall clarity with dark transitions.

To do a little update. Receive a XL2546K -> 3 bright dots.
Ordered a new one -> a big scratch on screen at unboxing.
6 XL2546K (4 on amazon, 2 directly on BenQ Shop) I tried and NO FUCKI*** ONE is flawless, that’s such a shame for BenQ.
I am completely bored about that company with actually no QC.
I might end on the Acer because I can’t spend thousands of euros to get a flawless one. The monitor is perfect to me but I can’t stand too many defects.
I feel so bored.
you were really unlucky, i had four perfect ones
I noticed you have the Acer Nitro XV252QF & ViewSonic XG2431. Which monitor are you liking better for games like PUBG, CSGO, Valorant etc ?
Between the two minitors, for games like Valorant and CS I recommend Acer 390hz, input lag is lower and feels, for other faster games the XG2431 is much clearer, which could benefit you. Besides gaming it depends on what you prefer, Acer has less input lag and is smooth, Viewsonic is clearer.

Did you guys see the comment someone posted at rtings for this monitor? Lol
There is 0.2ms variation between this monitor and the two other 360hz monitors tested, absolutely unusable :lol:

I just ordered the XV252QF, maybe I will make a video comparing 280hz strobing with 390hz strobing, I was a little bit worried because I saw a guy complaining about input lag early in this thread (which was debunked by this last finding + optimum tech and fr33thy results) and someone saying that it was a terrible monitor for Overwatch (I know an EU Contender player consistently top 50 that uses it as his main).

My issues with both the 2546K and VG259QM were that I either had to strobe with overshoot or there was no point in strobing at all, OD locked for the Asus and AMA Off on the Benq was suboptimal, AMA high and Premium were similar to OD80 with the Benq hiding overshoot slightly more due to the insanely long strobing window [ 83.3% vs ~70% on the Asus].

Can't wait to test it in Overwatch and Apex.
Awesome! Let us know how you end up liking the monitor. Would you not recommend the XL2546k for someone that already owns the Acer 390hz? I main PUBG right now and I never reach 390 fps in this game. I really wanted to try the Benq but idk if it’s a smart move for what it cost.
Yes, for PUBG the XL2546k is better. There is no other game then PUBG where visibility is such a huge factor.

TGLTN pro PUBG player was ranting pretty hard in his stream after he had to play on a sponsored IPS 360 hz Alienware on a Korean PUBG tournament and lost early on. TGLTN ranted that he does not care about beautiful colors or inputlag in PUBG when there is motionblur. The Dyac and the TN panel on the Zowie XL2546K where essential for the lowest motionblur and best clarity possible. He literally said IPS is crap for PUBG. I don't think he only said that cause he just lost in the tourney.

I remember playing PUBG on the Zowie XL2546K the visibility was extremely good.

The colors of IPS displays are only superior on the esthetic side.

On the TN Zowie XL2546K u can change the colors and sharpness making the enemy's stand out like nothing else. It reminded me of a extra digital vibrance setting to make the enemy's "pop out" so they can't hide in the darkness or somewhere else.
For visibility (and thereby tracking the enemy's) the colors on the TN Zowie XL2546K are way better then the colors the IPS panels generate.

On most IPS panels u can't adjust the colors or sharpness. On the IPS Acer 390hz u can adjust the colors a little. But because of the low brightness the motion blur reduction (VRB) gives u not really notice it. Plus these settings cannot be saved! (Its a bug!)

On the IPS Acer 390hz with VRB on extreme there is more blur then on the TN Zowie XL2546K Dyac plus with VRB on extreme the Acer 390hz is not very bright.

If u only play PUBG and no other games the XL2546K is the best I think: U see enemies the best.

Also keep in mind: AUO is working on a 24.5" 1080p 360Hz TN panel for a while now. https://tftcentral.co.uk/news/au-optron ... -july-2021 Zowie wont be using IPS imo. The difference in sight is to big compared to TN. So they will prob. again use a AUO TN panel.

When Zowie comes out with a 360/390/hz TN DYAC I will definitely give it a try. It will be the best of both worlds.

I asked Zowie on 9 feb. 2022 the following on https://twitter.com/ZOWIEbyBenQUSA/stat ... 1191024642
"@ZOWIEbyBenQUSA
I know u probably can't say anything about it, but I am kinda desperate: Can u give any info about a TN 360 1080P DYAC monitor, is there any possibility we can see this monitor in 2022?"

the answer:
"hi, thanks for your understanding about i can't say anything for our future product plan :)
but we do keep developing new product, hope we can have good news to share in the near future ^_^ "

I´m happy that Rtings finally reviewed this model! Now I can tell other users on this forum that it isn´t the fastest monitor on anything, be it input lag with strobing or response times, without mad buyers saying "do you have proof? It is the fastest monitor ever, deal with it etc etc etc"

We now have numbers from the best reviewers on the internet. And they tell us that with strobing activated this monitor even at 390hz is slower than even a 240hz monitor. Yes guys, strobing adds input lag, not only 10% more. It is clearly noticeable:

1,8ms vs 3,0ms according to Rtings

The numbers also tell us that Acer Nitro 390hz doesn´t even belong to top 10 most responsive monitors on rtings, pixel response time wise. The top 10 is obviously full of Oled and TN screens, from 120hz to 240hz (so the 390hz can´t even make up for it)

Nothing on this review is surprising to me. It just allows me to have actual numbers to put on here next time someone claims this as "the best and fastest monitor for gaming".

Is it bad? Far from it, no! But it is also far from the best of the best models for competitive play. Wich explains why no relevant Elite player is using it. Think about it

Cheers

Maybe I am not looking at the right lists. But both on https://www.rtings.com/monitor/tests/mo ... ponse-time an d https://www.rtings.com/monitor/tests/inputs/input-lag the monitor is in the top 4

EDIT Ah i see what u mean. You have to sort the row on Black Frame Instertion But then still its on place 4. See https://www.rtings.com/monitor/tests/inputs/input-lag then sort the row BFI

EDIT 2 Or do u mean sort on Response Time @ Max refresh Rate Total Response time? https://www.rtings.com/monitor/tools/table/77331 Then its not in the top 10.

Absolutely correct, 60% off duty cycle according to RTings Backlight graph.

I'm surprised to see that, with OD Normal, it has the lowest response times and total response times mode with no overshoot among the other 360hz monitors tested by RTings, I thought that the AW2521H would beat the XV in this aspect.

The numbers also tell us that in that top 10 there are 7 LCD and 3 OLED and all 7 LCD panels suffer from overshoot to a degree, response times ranking is a meme when Rtings itself claims that 8.6% avg overshoot for some monitors is unusable and 23% Overshoot on the G9 is "the best mode".

Don't take their rankings too seriously, just use that site for their response time tables and graphs.

The guy currently Rank #2 in R6s (Spoit) is using it as his main right now (he's streaming as I'm typing this), he was previously using the 2546K, I asked him on stream what he thinks about the XV252QF (he's using it at 360hz because R6S is buggy).

He said that the 2546K is indeed clearer but the difference in smoothness and latency is absolutely worth the upgrade.

Yes. This review fully explains why Elite players and professional gamers around the world are opting for this instead. Think about it :D
