About AG275QZN (BFI)

Post by Klemc » 05 Mar 2023, 11:36

Hello,

i finally found the non-curved VA panel and it's 27" 1440p like i wanted, but it's 240hz.

My PC is meant for games, from 2012 to 2022, all types from point & clicks to FPS, even 2D, and some rare are locked at 60hz.

I set always all to 120hz because i prefer image quality and often use DSR/DSDSR to annihilate aliasing, also why 144/165/1xx. it's not a round number :p

//

How will behave this 240hz monitor at 120hz ? Thay's the question !.. I will rarely be able to handle games at higher rate than 120 :

4070ti
7800X3D (soon)
B650E-E (soon)
2x16 Furry R. 6000/32
...

From the interest taken in this monitor and not beeing tested reviewed anywhere should i undersand it's out of a full crap and untrustable to be good ?

There are reviews of that monitor on youtube. Just like other flat VAs, it has a slow response time. If that doesn't bother you, everything else about that monitor is ok.

There is no need to limit the monitor to 120Hz on adaptive sync monitors. Just make sure to use a DisplayPort cable, set the monitor to its maximum refresh rate(240Hz), enabled G-sync in the nvidia control panel, and then set a global fps limit of 237 fps.

I also suggest using the medium overdrive in the monitor OSD. it's the best overdrive on that monitor.

Great one, it's since yesterday i have it, and it's better in every way to my previous too big too 32GN600-B (VA).
A new sight on all my games :p

Thanks, i did how you said i should.

It's about BFI, a question more appropriate to the BB forums.

//

It's a BFI that lets choose between 20 values going lighter or darker from 1 to 20 (0 is off), it's AOC, any knowledge about it here ?

According to this review, the highest overdrive setting at 240hz seems to have a ton of overshoot (typical of VA).
So you got two options:

1.) Highest refresh rate, no BFI
In this mode, as the comments above have mentioned, you should use the 2nd OD setting to avoid black smearing.

2.) Best response times possible
You could attempt finding out what the max refresh rate is before you start seeing smearing on highest OD setting (probably 120hz-165hz)
This would result in a overall more responsive experience and perhaps a bit more clarity than the above option

3.) Strobing
If you are able to use MBR on 120hz (some monitors lock MBR to max refresh rate only), most definitely considering doing the QFT trick and enable MBR at whatever option results in the best motion clarity with least amount of crosstalk. (note, use highest OD setting for this hypothetical scenario)
If you cannot run MBR at <240hz, then it's not worth considering BFI imo.

This article will detail how to use CRU's Vertical Total Calculator if your panel supports MBR at 120hz (or if you want a lagless 120hz mode, which could be preferred as response times would drastically improve and smearingcould/shouldbe close to non-existant on highest OD setting at 120hz)

1°) 240hz with Freesync ON/OFF on medium overdrive, OKay.

2°) BFI is better when used at 120/165hz,.. that's what it means ? Highest OD setting darkens screen when selected, others don't.

I've not the impression i can make any difference, this monitor looks to have good motion clarity.
Game used was PRODEUS.

If you cannot run MBR at <240hz, then it's not worth considering BFI imo.

I was reading TechPowerUp's VA topic and found about QFT right before reading here, so, i'd look at it more seriously for 120hz (it works 120hz MBR, pics attached, set to 1>20 range available too :) ).
BFI's disabled by OSD if OD's set to highest (called BOOST btw), but others work.

MBR enabled right now (Fsync must disable), monitor is at 240hz (desktop) set to 1 it's lighty, 20 is darker, 10 looks correct.

Set to 120hz, MBR's fully working (all hz except 60 work, at 60hz OSD disables/grays OD setting).

Well, that's complicated, FSync ON/OFF with OD medium, will be what i use globally.

About BFI, i will try to handle it correctly (set QFT-CRU), i could see some difference in PRODEUS at different settings, but i will have to take notes and be sure of what i see too :p

The best way to judge motion performance would be to use https://testufo.com/ghosting if talking about non-strobed scenarios or https://testufo.com/crosstalk when talking about strobed scenarios (to judge severity of crosstalk)

The most important thing for strobing is that you are supposed to run the game at fps = refresh rate with no hitches. It can be quite cumbersome to make this happen in modern games (and strobing is somewhat of a bandaid for the way we perceive motion on displays) especially as the refresh rates increase.

As you've mentioned, VRR/Freesync On or Off (depending on preference) with OD Medium is the easiest and fastest way to setup the monitor without fiddling with QFT.

I need this tests to be available offline, this PC is not near any internet connection, it's offline !!

I want to do all tests i can and report here the results, it's a monitor that RTINGS wanted to test but it's not sold in USA bc /EU part.

If not available offline, i'll have to plug the monitor in my DeskMini X300 that works with an APU 4650G-Pro.

EDIT :
OKay, it's connected to DeskMini
EDIT2 :
STUTTER WARNING:
Browser stutter detected (1+). Close other apps and tabs
Well, that is bc 240hz on iGPU (APU), but not advertised at 120hz ;(
