I've been using 120hz BenQ XL2420T for 10 years now and I've never tested anything over 120hz. Just ordered this and ASUS VG259QM just to compare if there is a lot of difference. Mainly play CS:GO with about 350-400fps. Should arrive in a couple of days.
I noticed Notty_PT talking about AOC 24G2Z or ViewSonic XG2431-monitors but neither of those models seem to be available in EU.
It will be a nice upgrade over your classic BenQ, but also pace your expectations if you've been watching Youtube videos. There's always so much hyperbole in the reviews for this stuff. Most meaningful upgrade and biggest jump still is and was initially going from 60Hz > 120Hz/144Hz and getting decent pixel response time panels. Ever since then it's felt like baby steps with
a lot of marketing bs & paid reviews hovering around the whole industry. I as a sucker buy in every year.
Especially for something like CS:GO which is not super-fast movement and pre/aiming mostly happening in horizontal lanes I feel you don't really can't get a lot of actual competitive edge after a good responsive 144Hz. But certainly there's a visual difference and some feel difference. Some more fast paced arena shooters where stuff is not predictable and happens all around + up and down, will benefit more from tech like this.

I just got my monitor. Overall, I think it’s a solid improvement from my AW2518H. Display lag feels lower and the higher refresh rate is noticeable. However, is it strange that black frame insertion feels almost the exact same on or off? Is it because the refresh rate is already so high? I mean, I can see a slight difference on the UFO test, but it really doesn’t feel better or worse with it on or off in game.
Funny you say that, I have this monitor and felt the exact same way. I actually thought it wasn't working at first when I tried it in-game. I was skeptical until I tried the UFO test where is fairly easy to notice the difference, even though it isn't massive.
I choose to use VRB Extreme always, but the only situation I can really feel a difference (in tac FPS) is spraying, where people are somewhat clearer. Whether that clarity actually translates into better performance is unclear.

I actually noticed it a bit while spraying too. I will have to keep trying it out and messing with the settings. Since the difference is not that noticeable for me, I might keep it off for the small latency benefit. It seems like you, Discorz, and I have all had similar experiences.
The two things I'm certain I can notice are the extra frames and the reduced latency. Just moving the cursor around on the desktop (keep in mind, this is with DWM - without it there would be even less latency) feels as though it's happening exactly as I move my mouse (Viper 8K). Have you ever looked in the mirror and thought about how you wouldn't be able to tell if you or your reflection was moving first because it's at the same time (obviously it's you, but if you didn't know which was the real one it would be impossible to tell)? Well that's how it feels with this monitor. Also, the extra frames are insane in games like Rocket League where they are easy to get 99% of the time. Just following the ball and turning the car instantly shows the massive benefits of higher refresh rates.

The contrast and RGB values trick only worked on TN panels for me. What am I missing here?
I thought they worked for IPS too. I could be mistaken, however. Adjusting them on my own XV252QF did seem to reduce ghosting. I have mostly done it on the monitor itself. I would think it would work on all panels considering it is making the toughest transitions less pronounced by avoiding them in many cases.

Have been lurking this forum for awhile, decided to hop in now. So hiya!
Bought this Acer 390Hz. Didn't really need it. Saw some big hype online. Then there was a deal at local shop for 350€ for damaged packaging readily to take with. Could not resist.
After using it a week or so, coming in from MAG251RX. Sure it is a slight improvement, but slight is the keyword here. It's smoother. Input lag is the most impressive thing. First time ever it starts to feel hand movement correlates to screen in the same instant it happens. That is the best thing about this.
Response times on the other hand... Man it's a bit hard topic. It's not perfect. It's good though. Very fast paced things still can get a little messy moving. VRB Extreme helps but does seem to induce a strange brain pain for me and while it sharpens the fine details there's still slight trailing or crosstalk which was maybe the annoying aspect of the movement in the first place. Maybe I get used to. Coming month will tell if I even end up using it.
Even though this might provide some quality of life to be had here and there, I hardly believe it's a tool which would allow me to get any better compared to something like MAG251RX.
Menus, settings and navigating them is a mess. How hard can this aspect be. Gladly default settings are pretty okay and currently VRB is the only setting I tinker with.
do you mind to tell me the store you bough?

Actually local store in Finland called Jimm's. They every now and then have interesting single deals on "B-stock" monitors. Sometimes a return unit, sometimes demo unit, sometimes dead pixel etc. Was surprised to see this 25% off msrp over a damaged package. And the damage was minor.
The good price I got it for ended up actually being the only reason I kept it. If I would have bought the same panel in over 7xx€ product like the Asus a bit earlier this year, which I was tempted to. Can't say I wouldn't have felt slightly ripped off. Something 3xx€ feels more accurate for what it actually is compared to rest of the gaming monitors you can buy.
Then again I see you are in the monitor market for CS:GO. There is absolutely nothing wrong with this one for that use case. With this you'll know your monitor is one of the best in the market for the task you're doing. Some might prefer Zowie. Some might prefer some 240Hz model. But we really are in the hair splitting territory where it's only pretty much subjective opinions of qualities people prefer. Which often tend to change, with a bit of getting used to.
In reality anything you buy won't be perfect. Any "good" 240Hz IPS is a solid choice. Even any "great" 144Hz is a solid choice. Especially for something like CS:GO (It isn't THAT fast) I really would advice not overstress the gear. I play faceit lvl9-10 and have played for some years in the same level no matter the monitor used given that it is "good enough" meaning 144Hz sub 4ms input lag and response times. I have stressed and spent way too much money to this stuff thinking it will take me to the next level. No it won't and based on my actual experience can't recommend it if you're expecting it to do miracles. Only you and your team can do it by training more + playing better and smarter.

Alas from my last comment, where I do think it can be trivial for actual competitive edge (in tactical shootters) I do think it's a nice hobby testing these things out. And if you take it for what it is, it can be fun also.
I took some ufo shots this morning. I think this monitor does perform very nicely with VRB on extreme.

Thank you for doing it. I must point out tracking and shutter are invalid. Its still a decent demonstration tho. Very similar to ms.potatoe
shot. ISO is nice and focus is very crispy. Maybe try again.
The
Sync Track must be aligned vertically like
this.
Shutter needs to be Hz/4 when doing
pursuit photo/video. If your camera doesn't have exact "Hz/4" option then choose one step longer speed (e.g. for 390z would be 1/98, choose more common 1/90 or 80 instead). For
static capturing on strobed display it needs to be Hz=shutter.
Can you do a
fullscreen crosstalk test? Everybody seemed to review only middle of screen and it can look much worse on top and bottom of screen. Something like
this.
Do you have the Aopen 25XV or Acer XV25? They are the same, but im just wondering.

Thanks for your feedback. I will try again and more during weekend.
For some reason my PC is struggling real hard to get perfect sync even with ghost ufo being the only test run on browser @ 390Hz. Never had same issue with 240Hz. Any tips to get sync better?
I noticed that the slower shutter speed I set the harder it naturally became to capture realistically as the shutter is open for longer period and then collecting all of the possible shakiness of the hand and movement which then instantly correlates to the photo taken and it also makes the individual pixels more blurry to the point where you can't discern them. Even at 1/90. I maybe don't understand the principle why you could not just go overkill with fast shutter to capture the instant moment eliminating all the human movement out of the equation. Results with faster shutter look more consistent and in line to what I'm actually experiencing looking at the monitor. Maybe. Must try again with slower shutters and syncing up the track better. Maybe I try to build some diy rig if to make it easier. I'll try static capturing and the fullscreen too.
I do have the Acer Nitro XV25 model. I think (might be wrong) there might be some slight differences in the firmware. Many seem to claim VRB goes off when booted. Mine does not seem to do this. Also some menu options seem to be named and act slightly different to US reviews. Manufactured FEB21. GTX3070.

can someone maybe update and summarize with all know how information---exactly WHY they made so many versions for overseas? (yes I insist on calling it overseas because the first batch WAS from Wuhan China, not sure why I ever need to shy away from that) just to smokescreen the nature of it being not expensive to make and sorta dealing with the fact that if it is just ONE model from ONE brand, other brands still selling 360hz would easier gang up on it?
the complications for us enthuasiast is certainly not welcome in terms of differences in firmware and other stuff. But hey I would have to remind you guys again that what I paid for was 550 bucks or something. you guys got a very steep discount with the 299 or 399 stuff. #essentially the same thing that doesn't really go out of relevance in terms of user upgrade cycle within a few months#
did I mention somewhere previously already that the same 360hz panel that can be overclocked to 380hz and even 400+ only sold for 2kish or 3kish depending on if assembled in crude basics or just panel, not 1 months or 1.5months after this came online?
