05/22/2020 UPDATE. The IPS 240hz monitor tier list.(I've measured/tried the all) and my honest explanation why.

[SmoothVelvetSlav]

damn the VG259QM looks impressive, 240/40 looks amazing.

If your using OD40 instead OD60 @240hz isnt it slower then OD60? Why you dont choose OD60?

Ok so let me start by saying that OD40 is better than OD60 on the VG279qm.

With the standard ghosting test at 960 pixels per second there is barely any difference between OD40 and OD60, the yellow looks a little bit more bright than with OD60(which is something that can be applied to OD80 and OD100 aswell) and the UFO looks slightly less wide with OD40 on the left side of the UFO, but the motion quality looked about the same, even up to 1920 pixels per seconds with a naked eye.

After watching this video https://youtu.be/zmsLXxyeyMg?t=150 where the VG259QM was tested at 3840 pixels per seconds the reviewer came to the conclusion that OD40 is better than OD60 even on the 24.5", confirming Hardware Unboxed testings on the 27".

I tried to test it myself at the same speed at 720p480fps and I can confirm that OD40 somehow retain the image less than OD60, I don't know why.
The difference between OD60 and OD40 at 240hz is IMO negligible, OD80 manages to completely get rid of the ufos' blur on the darkest background but the overshoot is noticeable with the light blue background, especially ingame when looking at the sky.

OD80's overshoot at 280hz is extremely low, there's no color overshoot visible with Frog Pursuit, just a very light trail.
OD80 is clearly designed for the maximum refresh rate.

okay so im literally on the edge of my seat about to preorder a VG259QM. My only hesitancy is on the performance of PCs. Im planning on building a new rig come September implementing Big Navi and Zen 3. I have a budget around 2k for it.

What do you guys think will that run basically any game at 1080p on low for any game. Even badly optimized games like lets say Fortnite endgame?

This is my deciding point bc if i can secure a consistent 280 fps on any game then the VG259QM is a no brainer here. But if i cant i will get the MAG251rx or a respective Tn panel around the same price with the lowest blur/response times.

Also how do you guys like the monitor so far?..how's the input lag on it? anyone plays fps games like quake live..have you guys tried running it using 280hz? I'm wondering if it can be used with quake live because the maxfps is 250.

So far I'm happy with it, QC was good very minimal BLB and no dead pixels. I found the colors to be good, didn't notice much of a difference coming from a VA 60hz monitor.

Also I was pleasantly surprised by the text clarity, I expected it to be a bit blurry but on the contrary It was very clear. It was clear enough to the point where I'm totally fine doing reading and school work on it, I can't say the same for the Tn 144hz monitors that I've previously owned.

I mostly play league, I also tried out some Overwatch. I noticed no input lag everything was snappy with no delay even though my fps was fluctuating (160-240) not sure if it normally would have any effect anyways.

Overall, would recommend.

1.91ms g2g. 12.5% overshoot @280hz refresh 80 OD. 0.5ms g2g 75% overshoot at OD 100

That shatters the fastest TN and it has a +40 hz refresh rate advantage

The fastest TN has been shattered(nitro xv253q/omen x25f) and the overshoot is feint to the point where the trade off of MPRT and sharpness of g2g not cause distraction

The vg259qm broke records for a playable response time. Btw u dont have a choice at 280hz picking 80 OD bcuz ghosting and smearing isnt worth it over feint overshoot that dissipates very fast
,
Also elmb sync puts the nail in the coffin if u want more.motion clarity, no tearing and microstutters and no ovrshoot. With slight input lag

This is contingent if u are able to get fps above 265hz.


U could revert to 60 od but the smearing and less sharpness isnt worth it over the feint overshoot. Overall everything has a trade off. U have to sacr8fice one thing to get the other.

RLCScontender, will there be a full review post on VG 259QM or is it done? because i was hoping for a full summary like you always do, if there isnt dont worry about it ill just read up on the previous post, but i would love to know if you going to make a full post on the review on VG 259QM.

i have another question as well about console gaming since you play PS or Xbox, Since from what i know ps4 pro goes up to 4k resolution @ 60hz, so does this mean in a imaginary scenario where a different monitor with 4k resolution and 60hz max IPS but with the exact same inputlag and response time with MSI MAG251RX, will the experience on playing a console be better? than a regular 1080p IPS panel?

and another question regarding pc games. 3rd question, some pc games like on steam (Ori the will of the wisps, Hollow knight) runs at 60fps max, does this mean that if i had VG279QM the 27inch variant does it mean the input lag is very very bad at 60fps capped by the game, but i run at 240hz or 280hz on nvidia? since vg279qm handles 60hz badly?
Do i need to see review for most 240hz monitor running at 60hz before purchasing if i plan to play games capped at 60hz (steam games on pc)? or it doesnt work like this?

Looking forward to your reply and also anyone else who knows the answer to this, Thanks in advance and stay safe everyone

ugh i cant decide whats the best monitor for me if half my games run 240fps, and the other main ones run 140 fps. I was leaning towards XL2546S but tinkering DYAC strobing at different hz just seems like a hassle to fine tune. i just want a monitor that i can buy and look good at all FPS

[RLCSContender*]

The best tuned backlight strobing for a 240hz ips is the the viewsonic elite xg270. And yes, strobing a 120hz and 144hz is excellent for competitive use since the dbl images are basically non existant.

The msi mag251rx and asus vg259qm is also good since their OD tuning(faster for msi, and 60 for vg259qm) are good throughout its refresh rate range. Strobing for the msi is decent at 240hz but best at 120hz. Elmb sync for the asus is good only from 200hz and above bcuz of the locked OD

Hello,

Do the VG259QM have a build in Display Scaler? To use display scaling on 1024x768 in CSGO for example?

would you get the Viewsonic over new zowie xl2546S? from what ur saying out of IPS, either MSI or the viewsonic would be good for me.... i could drop my apex legends to 120hz with strobing since i can only get 150fps max there.. an which has better blur/ghosting/less artifacts with G sync with AAA relaxing titles with fluctuating FPS?
an lastly color, i was aiming for TN because i can keep my current decent IPS for video and photo editing... but in case i want to use only one monitor, maybe its better to have IPS with good color AND goodd gaming performance

DP 1.2 is 21.6 Gbps, DP 1.4 is 32.40 Gbps.
This monitor supports DP 1.2 so 1.4 is using 1.2's bandwith, there is no benefit in using a newer/faster DP cable.
I bought it just for future proofing.

The input lag is extremely low.
If you can manually tweak the config file of Quake (if there is one) maybe 280hz is achievable, Idk I've never played that game.
I can't consistently reach 280fps in the games I play so I stick to 240hz (so I don't have fps fluctuations messing with my muscle memory, which is something I notice).
The VG259QM works well at 280hz, there's barely any overshoot with OD80 which seems more aggressive than on the VG279QM at this refresh rate.
It's definitely usable.

Thanks for clarifying. About Quake yea you can tweak the config file and change the refresh rate but i'm not sure if it can go up to 280hz or if it's possible to make use of it if the maxfps is 250 fps. The fps fluctuates a bit in quake live so it's never 250 stable it goes to like 230 sometimes and lower on bad maps.

But in theory would using a higher refresh rate than the fps cap have any effects or benefit or it won't?
For example if the fps was stable at 250 and you used 260hz would that work or it would be better to use 240hz?

Also should I be using g-sync or free sync as well or would it add input lag?
what would be the best settings for using this monitor generally when gaming to get the lowest input lag?
