Acer 390Hz monitor - XV252QF

[BTRY B 529th FA BN]

Well the price just shot back up to $449h @ Micro Center.. infact all Acer monitors went back to original pricing..

Hh. I managed to buy new AW2521H (360Hz) for $460 with shipping in my country. Good deal?

That is a great deal, I bought mine back in May for almost 700 dollars. I made the switch from 240HZ=>360HZ and never went back since. The difference is incredible. Please keep in mind I don't even run @360HZ, I run at the maximum 240HZ (BFI) in 95% of cases.

I know there is a lot of talk about this new AOpen 390HZ monitor, and the main reason is BFI at up to 390HZ! Went to microcenter to check it out but it wasn't available, will check again as soon as it is there.

Also if you are very competitive, and u rely on reaction time, or play hitscan games. Any technique like VRB or VRR will add noticeable input lag. It feels more responsive and snappier with this off and just use overdrive extreme.

Other than that it is the best monitor I have ever used and played on. I also use it for ps5 and it feels very snappy on 60hz and 120hz coldwar.

Could you elaborate a bit on what you mean by VRB/VRR (BFI) adds "noticeable" input lag?

I have both the Acer XB253Q GX (240HZ) and the Alienware AW2521H (360HZ) and out of the two, using BFI on the Acer does increase the input lag slightly but on the Alienware, it is practically imperceptible. I am not sure as to why Alienware handles BFI @240Hz so well but it could have something to do with the Alienware having inherently less input lag vs the 240HZ panel.

I am very interested in knowing why these AOpen/Acer 390HZ monitors would actually show noticeable lag with BFI ON. Is it really that noticeable the way you are saying??

VRB adds input lag?

VRB adds input lag?

Yes! But not as much to be worried about. Some monitors can be tricky tho.

That’s why it’s so important to have a major database of independent data to measure these things. Someone could be fooled by G2G marketing nonsense like (0.5 ms response time) and end up buying a monitor that has more input lag than their previous one. I try to wait for RTINGS to review these things with their equipment before I make my purchase. It is also helpful for mice and keyboards. I really wish these latency differences had to be disclosed by the manufacturer. There is so much variance.

If you ask me GtG 10-90% linear method is bad to begin with. Thank god some reviewers like Ashun (Aperture Grille) and Hardware Unboxed started to use more strict 3-97% RGB.
What I'd like to see is something like Motion clarity metric that combines response times (3-97% rgb)(with blur reduction off/on) together with refresh rate. Because depending on refresh rate overall motion blur changes. I imagine this separate from overshoot. Like this. VRR strobing is about to become a thing.

Input lag results are rather weird, so I always take them with a grain of salt. I don't know if I should look at processing + refresh lag only or processing + refresh + response lag. Because response time is not something that should affect lag significantly, yet it takes the biggest chunk on HUB bar charts.
I just can't accept LG C1 TV @120Hz and Omen X 27 @240Hz have exactly the same input lag just because OLEDs have superior response times.

Look mspotatoe, Brandon Taylor used your pursuit shots in his review: https://youtu.be/s4omNr5723I?t=422
I checked, Its this shot . He was lazy to take his own lol. And he compared it to his non-strobed AW2521H with overexposed photo. Ouch!

I noticed he was able to change overdrive when freesync is enabled. Thats not what we concluded here: https://youtu.be/s4omNr5723I?t=188

, and to read the rest of the thread.

Hmm? I confirm that in my unit I cannot change the overdrive. Please, can someone with Nvidia GPU try to change overdrive with "Fressync On"?

It's not a game breaking change. It is still playable and feels good with vrb and vrr. But for me personally, after extensive playing, same servers, circumstances and opponents, I can feel and notice it in my aim and reflex shots/reaction time when one of these features are on. It's for me that perceivable that I rather play with all these things off and have a bit more motion blur (tbh on 390hz the diff is really not that huge) than playing with it on. It also feels like with my Nvidia GPU, the input lag is more noticable with vrr compared to playing on my previous HP omen 240hz tn panel that was "g sync compatible". Maybe with AMD and freesync premium it will feel better.

Bare in mind that this is all personal. I'm a geek when it comes to reducing input/system lag, using latency Mon, overclock my stuff, smt off, hpet off etc.

I also paid attention to how I was feeling, tired, awake/fresh, cold hands etc in a period of weeks, to see if it was a placebo effect, and some other factors beside my PC and monitor gave the feeling of a "less responsive input" when these things are on. But for me it was clear. Maybe for others it doesn't feel any different, maybe even Acer claims that it's not affecting input lag. Just see it as some people won't notice diff between 240hz and 360hz and some people do.
