Acer 390Hz monitor - XV252QF

[lizardpeter]

people who live in the gulag had to get with in order to survive, but when choices are available and you don't have all the time in the world to experience it all and compare, or experiment on practicing your endurance with crap gear to boost your raw skill and potential, nobody would intentionally pick the worst one

these things are all overpriced electronics garbage in the end. I paid for it cus it was cheaper than the 360hz ones, simple as that. It was no surprise to me that the price dropped domestically and internationally(release dates I don't exactly know or care to pinpoint again), demands were just really low or none existent, they still kinda were after the price dropped (did someone say price came back to :normal:?)

I'm kind of confused as to what exactly you're saying. I saw your comments earlier in the post, but I was not sure then either. Do you like this 390 Hz monitor, or are you saying other options are better?

Also, the price of which monitor dropped? The Acer 390 Hz? In the United States, it has seemed to me like the price has been exactly the same and that the demand has skyrocketed. On Amazon, the monitor is backordered for a month now.

I've received my XV252QF from Amazon yesterday, sadly it has a bad flickering problem, the same shown in this video:

https://www.youtube.com/watch?v=bPn5avXjSoY

The problem presents itself only @390Hz with overclock active. It goes away as soon as I switch to 360Hz or less.

I've had my XV252QF for about a week and can confirm this issue. It appears to be an issue of the GPU really not enjoying 390 Hz. After reading what others wrote, I've decided to test it without any other monitors attached and suddenly 390 Hz "works". The catch is that my RTX 3090 Founders Edition really, really struggles with it. Suddenly I ran into GPU driver crashes and degraded performance. Everything is fine up to 360 Hz, but with 390 Hz it starts crashing and losing performance. No idea how that makes any sense and how a monitor's increased refresh rate could make a GPU go crazy, but it's reproducible for me.


There are also a few more firmware issues, like the already mentioned problem of VRB turning off with every restart (or sometimes randomly) and I've discovered that most of the controls for vibrancy boost etc. don't do anything while using VRB. You can clearly tell that they are working when used without VRB, but as soon as VRB is on, it's over. The black equalizer is still working, though.

There are also many other settings affecting each other and randomly resetting shit you've set in a different menu. It's kind of annoying to dial colors etc. in because of it, but it's not a dealbreaker. You just have to do them in a different order and suddenly it does what it's supposed to do.

If they can release a firmware update that fixes all the weird little bugs and inconsistencies, this monitor is going to be great for the price point. Even now it's really good, it's just... annoying and buggy. Maybe other owners could say which GPU they are using and if they are experiencing any odd issues when using 390 Hz.

I am sure if u follow my comments you would have heard a million times that Nvidia simply doesn't care (as much) about a none lucrative market that is the fading PC esport spiel. Plus they don't own the entire monitor business, people buy TV for consoles and just....netflix or some stupid bs.....and as for their own cake, again, console titles ported to pc that runs on 8k 60fps, honestly at this point if I even have to ridicule this for you as if I need to be apologetic or trying to be nice......then I don't know anymore. If u know, u know.

so yeah if they could optimize most pricy "premium consolewannable cards" it also for high hz and fps, they would gimp it. if they couldn't, they wouldn't go out of their way to try.

It's a real shame because Nvidia at 2017 was so adamant and out there, they released I Am AI as literally the opener to their GTC (conference) keynote by Jensen Huang himself (around the world). The first line literally went " I am A Visionary". And they used Starcraft 2 there as well, "I Am A Learner". It's like Jensen Huang saying "I know I'm just a tech guy but I still remember my roots of being a fellow og gamer and I still have passion and love for the pcmr and real hardcore games that people had to run all low graphics to get the competitive edge"

it was 3899-3999RMB and I paid around 3799 and got a price check after posting world's first and only (to this date) legit reviews, all extensively 10 videos of it, courtesy of Blurbuster TestUFO minisite assortments of tests. It had gone on sale randomly for 3599, 3499 and last seen was around 3199 or some such. The only and og distributor tried to contact me to promote their lower end stuff (144hz and the likes, also Acer, but honestly I don't know or care to know at this point if he was only in charge of Acer sales or whatever cus that store doesn't just sell Acer) and I politely refused because I have no need for them and have by about now been waiting nearly a year for TCL's 480hz.

------------
EDIT:
I forgot to add that he already paid a casul that only did cheap cpu steals or mobile steals vids and doesn't even play pc games (much, at least certainly not competitive games). When I found out about him having received it for free some at least 2-3 weeks after I got it first in the world, and questioned the legitmacy of such a payment and of course as it turned out his video was extremely elementery and didn't get much views or praises either, their vague words turned to "i need to return this", but apparently bilibili platform has auto feature in the background that allow random vendors to send out commission requests that randoms can "accept", this is what I hate about the entirity of consumer electronics and the people who have the audacity to begin to yap about them as the standards of entry get lower and lower even though things were supposed to be more and more sophisticated as time moves on. Yeah everyone's heard of PUBG/CSGO, not everyone was OG and I don't need to go out of my way to explain my arma 2/cs 1.6 roots to every kid who's only gamed for 3 years or something that presume that there is a common ground that he can speak to me as equals or even question and condescend against the unqestionable heritage that I and many others represent. Well I can tell you he was paid at least 1500 RMB for it on top of getting it for free to at least test it and play around even if it was indeed returned (and tell me who the heck would wanna pay for such a used and unboxed thingy? What on earth were they gonna do with it? shady af) Whoever contacted me claiming to be the owner of the seller ("but also I have bosses you know", so he obviously don't have much say as far as Acer command chain goes, and Acer clearly not smart enough to reward the only one that cared to bother) hasn't responded once since so yeah I'm entitled to talk about this bs. The customer support claimed she left the company, but they clearly know each other and even clicked likes on wechat, I asked about it and she blocked me. HURDUR. Well I tried to be as nice as I can. I still defended them against ignorant bad reviews.
-----------------


the other 360hz stuff as I already said were 5499-6499. One or two of the earliest quad or 5 lineup weren't available or maybe still aren't. I stopped checking. It's not like Nvidia are releasing more anyways they have been patching in lower hz higher rez stuff into their low latency lineups. But again this is not even 390hz. it's like a slight backstab, much like Razer releasing 8khz and claiming it don't work on Nvidia certified Gsync 360hz ports. (i've got one guy claiming it does so far, not taking his strand words for it, not that it matters really since we know that 8khz wireless isn't possible else Corsair would have nabbed it like they nabbed their version of 3399)

Oh and again if your game can go up to 600fps, even if just briefly, you can benefit from it, period.

Also aren't you one of those guys who said "who are you should I know who u are" on twit? Are you still gonna claim that here?

Wasn't that optimum tech guy, the one that preferred using Strobed 240hz with 144hz input lag levels, instead of 360hz? :S

I mean, I dont really care about that reviewer

Rtings are great tho!

So you're discounting his hard input lag data because of his preferences regarding blur reduction? All the while stating "390 hz has more input lag than 360 hz" as a fact even though it's literally based on your "feel" that no one here seems to share. Sound.

Afaik he didnt compare 360hz input lag to 390hz

Plus he is using Ldat wich everyone on this monitor scene knows is flawed

I only care about rtings input lag numbers because their methodology is the most accurate one and better translates to actually feel

And yes, I do not care about a reviewer that:

- accepts to play 144hz input lag levels on a 240hz strobed
- uses Ldat to measure input lag
- uses games like Valorant or Apex Legends to measure his aim

I mean, he is a casual. I rather take my own opinions and Quake players opinions.

Plus, you should not feel offended about someone else opinion. I have this monitor in front of me right now. I do not like it, I think it gets completly smashed by AOC 24G2Z or any other model using a matured 23,8' 240hz/270hz panel from Innolux. They are better than any 360hz model right now.

Let it mature and maybe things change.

360hz/390hz are not good enough right now Just like the first 240hz monitors weren't.

Plus imo the jump from 240hz should be 480hz

These are all my opinions, not the universal truth. If you like the monitor and you are doing well on your battle royale or overwatch type of game, great!! Most important thing is having fun with your devices. That is why we buy them right?

haha, well the case is many people live in their own bubble or circles of bubbles and just pretend they are safe there. You don't need to go out of your way to accuse them either, they and their narrow ways don't even deserve that attention or validation. If they gonna go out of their way to take offense over either your native opinion such as you were, such is your right, they are just offending themselves. Don't forget that you can just as easily be like them so we should all mind our standards.

As for Rtings I don't know where you are coming from that you praise them so in terms of monitors authority, but hey since you flamed apex/val I'd like to hear you out.

after posting world's first and only (to this date) legit reviews, all extensively 10 videos of it, courtesy of Blurbuster TestUFO minisite assortments of tests.

Where can I find these extensive videos?

But again this is not even 390hz. it's like a slight backstab.

Why is it not 390 Hz?

I have no idea what you are talking about. You have the wrong person. I don't post on Twitter.

I’m actually leaning towards the Nitro a bit more now.

I can tell you from my limited experience with it that it's really fast. On the UFO test at 1920 pixels per second, there's almost no visible ghosting at all. However, this is with my own settings and the known contrast reduction trick. I have the overdrive on extreme, the brightness at 100, max brightness on, black boost at 10, and contrast at 0 (increase this if you need it to be brighter).

I am alternatively trying overdrive on extreme, the brightness at 100, max brightness on, black boost at 10, contrast at 10, and BFI on extreme.

They are both very solid options. I am not sure which I like more. I will have to do some testing.

Wdym by contrast reduction trick?

yeah well one guy was telling me I don't know what viper 8k can do and either him or another guy was like apex pro tkl hurdur (something similar) but yeah.

What I was saying is that ACER's stuff gets bad sales because they literally flamed, in their own listing pics, the pricing and features of "A and B and C such competitors", aka ThOsE OtHeR 360hz monitors. What do you think Nvidia was gonna feel about it? Nvidia should feel ashamed themselves they didn't push 360hz or 480hz sooner.

I tested FreeSync on my Acer XV252QF (unit manufactured in March 2021) and while I can switch to Overdrive [Extreme] just after enabling Freesync, it does go back to Overdrive [Normal] after clicking the tickbox in Nvidia Control Panel in order to turn on the "g-sync" function for it to work properly. I played with the FreeSync a fair bit and yeah it basically does what it is supposed to do (I was using RTSS in game overlay and the HZ were changing relative to the Frames per second, like they should on a VRR).

Edit (21.09.2021 21:00): I just tested if I can somehow recreate this weird black screen flickering from this guy that was playing CS:GO on 390Hz. That's what I did:
- Brightness [100]
- Max Brightness [ON]
- Overdrive [Normal]
- VRB [Extreme]
- Overclock [ON] (So I can use the 390Hz instead of 360 of course)

Paired with a GTX 1070, I7 8700 & the attached DisplayPort 1.4 cable.
Was getting consistent 350-450 frames in CS:GO on lowest settings. In Overwatch the frames did go past 280 as well at unlocked framerate. In Smite without a problem 360 fps capped.

Conclusion (at least for me, with the March unit I recently managed to buy):
Everything works properly, there are no side effects nor weird unexpected behavior of the monitor/panel itself. Was playing CS:GO 3 hours, Overwatch for an hour and like 3 matches in Smite. The image is really, really crisp. The monitor works great, for now I'm super happy with the purchase .

you are not supposed to max brightness or benchmark brightness on high hz monitors. don't you guys all know that the basic principles of light sources refreshing from different imagery is that it takes time to go from black to white and the faster it refreshes the more rapid the quality of the material it has to be to reach the same brightness and if the quality is the same, it HAS to be dimmer the higher hz it goes.......?

Kind of like this trick the Chief was talking about.

viewtopic.php?f=4&t=4973

But I have also found success with reducing ghosting by lowing the contrast on the monitor as much as possible and by increasing the brightness to compensate.

There’s no way the 240 panel have faster response time than the nitro. Also nitro with VRB is extra clear.

Even Acer Nitro XV25 has better response times at 240hz. Try it and compare with 390hz. You can notice a lot less ghosting even on desktop. What does this mean? It means the current 360hz panels do not have fast enough pixel response times for 360hz yet, just like the first 240hz. I am almost sure Chief already mentioned this.

As for strobing on this model, I don´t understand how can someone like this strobing with so much better options for that scenario. I mean all it does is increase the input lag, add flicker (possibly headache) for a bit of crosstalk on the image that only makes things worse.

As always, my personal opinion. Try to play at 240hz for a bit and report back about the response times, everything will be suddenly clearer... even tho laggier because it was not meant to be used with a 240hz refresh.

After trying 240hz on nitro I have to say 240hz is a little bit clearer. But the lack of frames makes it looks as if it’s skipping a bit, on the other hand 390hz adds soo much smoothness and it’s almost just as clear. However in terms of in game, the 390hz is clear enough with much better tracking as there’s more frames, the 240hz extra bit of clarity is obsolete.

Of course! If you are running a game with more than 240fps you will for sure notice it at 240hz, while at 390hz your monitor will display every frame. I mean, that is easily noticeable, but does it make you play better with all that blur fest? It does nothing for me on Quake, I track way worse as the images are not clear. And what about fast flicks? Total nightmare compared to a good and matured 240hz panel

With these models I feel like playing on an very low input lag responsive mouse, with no frame skipping at all

but...

coupled with "10 years ago" awful pixel response time levels.

Maybe the upcoming TN 0,5ms 360hz panels, releasing soon, will be faster. I guess.

quake doesn't region lock anyways what are you even so keen about? spamming hitscan is no skill at all. As for flicking, I hope you aren't one of those people who blame ping over your own inferior skill in a game that itself (much as you praise said title) has massive amount of aoe abuse regardless of ping because that's just how the game's basic gunplay is made of-----even your precious hitscan is aoe, what accuracy? lol. there is no accuracy, not even the railgun, massive projectile AND champions hitboxes all around, much as to be expected from a series made in the potato resolution days. Oh please don't tell me you play quake on 4k and nitpick about high hz monitors tho, nobody's pc is optimized for 4k 300hz gaming.
