Just bought this monitor and want to tell few issues for else to think about.
Im running amd system with 5600x and 6800xt.
My previous monitors are Asus pg279q 165hz 1440p(secondary), acer predator xn253qx 240hz 1080p.
I wanted to buy this acer xv252qf to test a 390hz monitor since im really competitive in games and I am playing apex almost every day on a high level. Also Im interested in tech so theres that also. I know 390hz is overkill on apex and fairly useless compared to my 240hz monitor which ive been using for gaming for a year now. I just havent been completely happy on the image clearness and quality on the xn253qx.
Straight from the start I was having issues on turning on the oc 390hz mode on since I have multiple monitors. Ultimately I was planning to use all three of them and start to use vertically the predator one. But seems like I cant get them working all together. If im not mistaken this is gpu limitation since the 6800xt has only two dp ports, one hdmi and one usb c.
390hz doesnt also work if asus pg279q has oc mode on which gives you the 165hz. So in the end I can only use asus oc off 144hz 1440p as a secondary and acer xv252qf oc on 390hz. Guess i need to sell my xn252qx if this new acer impress me enough.
Its a bit bummer to notice these issues right away but i guess its understandable with all the bandwith limitations and whatsoever.
But i just wanted to inform about this if someone else is planning to get high refresh rate monitors to use with multiple monitor setups.
The acer xv252qf hasnt impressed me yet in image quality, input lag and clearness performance wise but need to test more different settings. This thread had some good suggestions I still need to try out.

Re: Acer 390Hz monitor - XV252QF
What’s the brightness loss like though? Based on Bijon’s video it looks like to actually be able to achieve XL2546K levels of blur reduction it loses a lot of brightness, in some cases rendering it unusable. Is that accurate? The main thing stopping me from buying a pair of these still is I can’t tell how consistently functional the blur reduction would be.Discorz wrote: ↑22 Nov 2021, 10:01⠀
Since XV252QF won latest RTINGS review, may I ask all true voters to go vote for new era Zowie monitor - Blur Busters Approved XG2431 with premium, flexible blur reduction on IPS. We finally got great performance at affordable price.
Vote for XG2431 at RTINGS
Here is a quick sneak peak. It's clearer than Zowie in this case scenario.

Bumping this question. Sorry if it comes across as pushy. Just genuinely curious and haven't seen an answer.Boop wrote: ↑02 Dec 2021, 04:44Does this also apply if the game doesn't maintain ≥ 360 FPS? Apex Legends will not let you go above the 300 FPS cap and usually runs around 200 FPS in the Battle Royale mode.Chief Blur Buster wrote: ↑01 Dec 2021, 18:04What mouse Hz are you using?
1000 Hz is no longer enough for today.
Many pro Apex players actually cap their FPS at 190 to have more consistent frame times. Would their 1000 Hz mice not be enough if they're using 360/390 Hz monitor at 190 FPS in game?

Re: Acer 390Hz monitor - XV252QF
The 190 cap should be fixed now. The game should also run smooth @ 298 FPS.Boop wrote: ↑13 Dec 2021, 04:55Bumping this question. Sorry if it comes across as pushy.

Re: Acer 390Hz monitor - XV252QF
I'm trying to find out if 1000hz mice are still "not enough" on 360hz displays in scenarios where some games do not consistently hit high frame rates. In some games you'll have very high FPS and then when a fight happens or more players show up your average FPS will drop by a significant amount. Not all titles run like Quake Live and CS:GO.The 190 cap should be fixed now. The game should also run smooth @ 298 FPS.
Quake Live - 250FPS is the cap and is very stable
Valorant, Apex, Warzone - FPS depends on fight (abilities used, number of players on screen, location on the map, etc). You aren't always getting ~300 FPS at times that actually matter.
Re: Acer 390Hz monitor - XV252QF
You are right and this is a good point. But you are talking within the realms of owning this monitor still? That was our point all along was that you are enabled to play the 400fps games. So basically we are on a revolving door still, but I'm still trying to be patient and catering to all.Boop wrote: ↑14 Dec 2021, 15:27I'm trying to find out if 1000hz mice are still "not enough" on 360hz displays in scenarios where some games do not consistently hit high frame rates.

Re: Acer 390Hz monitor - XV252QF
Thanks for the patience. Sounds like my thinking is correct in that some of the popular eSports titles are fine on 1000Hz mice until PC hardware can push framerates high enough on these 360Hz+ displays in the scenarios I mentioned. Most pros will likely stick with mice that have better shapes/weight even if they only support 1000Hz.lyrill wrote: ↑16 Dec 2021, 04:36You are right and this is a good point.

Re: Acer 390Hz monitor - XV252QF
Yesterday my 390Hz (Acer XV252QF) arrived.
Not sure if should test the VRB on 960 pixel per second or 1920 pixel per second on the UFO test site.
On 960 VRB is exactly the same on normal and extreme. On 1920 extreme wins: On normal the ufo windows are blurred.
What gives the best representation of a fast paced fps like quake champions, apex, valorant pubg? 960 pixel per second or 1920 pixel per second?
Last question: Does anyone have any other setting recommendations for me? Maybe on the color side? The 6 axis Saturate? All info is welcome!

Re: Acer 390Hz monitor - XV252QF
It's not really bugged. 390 fps just can't move 960pps at 2 ppf (390*2ppf=780pps). To look smooth it needs to move at integer amount of pixels (pixels per frame). Ashun explained this nicely in his video. You can check real panning speed here.
Using blur reduction on current gen LCDs at such high refresh rate already leans to ineffective side. Try and see if you even notice the difference between on and off (in game). I think VRB on this monitor has been exaggerated. If we assume Acer is using ∼60% strobe duration for VRB Normal this means you get 1.02ms MPRT improvement and 1.53ms for Extreme with ∼40% duration which is not much. And this is MPRT reduction only. This is nicely demonstrated in this graph, just imagine 2.56ms of 390Hz and 60%. Plus on top of that you have to add response time blur and if you're playing at framerate half of refresh rate e.g. 195fps you get image doubling.
I recommend you test all this in SmoothFrog and see how if behaves in different scenarios. You can toggle between ppf/pps mode, control framerate and panning speed, vsync... Add your own game images and pan them at fast speed to replicate fast movement.

Re: Acer 390Hz monitor - XV252QF
Tnx for the info. (I edited my original post a couple hours ago). How do u feel about testing VRB on 1920 pixel per second on the UFO test site instead of 960 pixel per second? Does 1920 pixel per second gives the best representation of fast paced fps like quake champions, apex, valorant pubg? I also tried the Frog program. But the ufo gives me more details I think.Discorz wrote: ↑17 Dec 2021, 07:20It's not really bugged. 390 fps just can't move 960pps at 2 ppf (390*2ppf=780pps).
