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

[Max_hz]

I think I will send the VG259QM back, in the 6 days that I have been using it I keep getting eye strain.
Take a break regularly but it will come back soon when I am behind the monitor.
Too bad I (thought) finally found a replacement for my old (2012) TN 120Hz.
Nobody else is bothered by this?
I use the monitor without sync at 240hz 60 OD or could it be that i have to get used to it?

[sk1p]

i REALLy did see a good performance advantage @280hz compared to 240hz, and yes 95% of ppl in the very high ranks use TN but i was able to react way faster than them just for the fact that i had a 40hz frame advantage. I was able to win more 50/50 challenges and i was able to see more especially if the ball is in motion and ESPECIALLY WHEN I MOVE MY CAMERA. Again, it's not a gamechanger for casual gamers, but if you are ELITE at a video game, ANY edge in performance will matter.

I played at 240hz this entire week to test if the increase in refresh rate% inside the window was worth the -40hz.
I mostly tested OD80 and OD60, OD80's overshoot leaves a white trail which is slightly noticeable only in dark scenes.

Yesterday I switched back to 280hz OD80 and the +40hz increase is much more noticeable than I thought the first time I bought this monitor, it does definitely feel more responsive.

Tim from Hardware Unboxed said that OD40 somehow performs better than OD60 on the VG279QM but there's barely any difference at both 280 and 240hz on the VG259QM, the only way I was able to notice any difference was by recording at 480fps and cyclically swapping between OD60 and OD40.

OD60 looks slightly better, but it's hard to notice even at 480fps and there's absolutely no difference , I do believe that the theory about the VG259QM having a different overdrive tuning compared to the 27" may be true.

I think that OD80 on the 27" is less aggressive than on the VG259QM (with the 24.5" there's some very minor overshoot at 280hz, which is similar to MAG's faster mode at 240hz in the Hardware Unboxed review and different from this VG279QM review [https://www.aperturegrille.com/reviews/ASUSVG279QM/] from a5hon which shows absolutely NO OVERSHOOT at 280hz OD80).

This is most likely the reason why OD80 doesn't have as much overshoot at both 280 and 240hz on the VG279QM.

OD80 on the VG259QM is more aggressive, it looks like 3-5% overshoot at 280hz and probably 10-12% at 240hz, that's why many VG259QM owners report that OD60 is perfect at 240hz, it seems like every overdrive on the 24.5" was boosted compared to the 27", causing OD60 to be more consistent at 240hz and even making it viable at 280hz even tho I don't mind OD80's minor overshoot at 280hz, the ufo/frog image is slightly better.

TL:DR
Best overdrives for each monitor and refresh rate:
VG279QM
- 240hz OD80
- 280hz OD80
VG259QM
- 240hz OD60
- 280hz OD80

With my VG279QM and 240hz I see better motion clarity with OD 80, but in CS GO it feels like my bullets aren't counted sometimes, but with OD 60 the game is felt in proper way. With 280hz and OD 60 I feel input lag more than with 240hz and 60OD.

For me two options affordable: 240hz and 60 OD or 280hz and 80 OD.

I don't get eye strain from this monitor on any settings that I've tried so far.

@ bleach
Thanks, yes It could be very personal, my old Hanns-G is so comfortable for my eyes, I think I skip the Asus for one day and see what happens after that, if it comes back.... hmm I hope not

Had something similar sometimes in the first month with VG279QM, sometimes eyes were red like after weed)) But now my eyes never tire from this monitor, work for 12 hours or sometime can play the same time. It's much better than my previous Asus VG248QE without flicker-free. I think you should get used to.

@ sk1p
Thanks,
I wear glasses for close by but with other monitors I was not bothered by it, maybe you are right and I have to get used to it, now take a break with the Asus and then try again.
Good to hear that it passed to you that gives hope again!

I Search the best gaming monitor 240hz for fast fps games and in the future ps5.. Browsing the forum, I come to the conclusion that the best is MSI and avoid Alienware 2521HF.. i have budget 550 usd. Maybe better wait for Benq XL2546s? i prefer 23-25'


In my country:
MSI MAG251RX - 520 usd.. not too much?
TUF VG259QM - 405 usd.
Nitro VG252QXB - 340 usd. budget option anyone recommend?
Nitro XV273X - 495 usd. anyone had this model? is very interesting.
HP OMEN x25? TN?

Are there any other interesting fast models worth recommending?

Sory for previous I beg your pardon, but my English is not good too.

[ItwasLuck]

input lag results for anyone curious on which has the lowest overall input lag. You would be surprised. The nitro xv273x is probably the lowest input lag of all the monitors right now(not named OLED)

the 25" predator has excellent input lag too. Man, i too was shocked. yes, when i played rocket league, you might think that 0.4 input lag difference is miniscule, but in a dexterity heavy game like rocket league, it adds up. one button press is 0.4, but if you press buttons in your controller 200 times a minute, this will determine whether you get a perfect blindsided shot on goal or a WHIFF that will send your car flyign open for a counter attack.

for competitive gaming, the acer clones have the lowest input lag but the worst g2g averages.*at least that's what i measured*

I am definitely keeping my Acer XB253Q GX. It is an outstanding panel, definitely not like that MSI you got from the lottery (Oh, do I envy you!!!). But regardless for gaming, I am having such a blast with this monitor. I did the human benchmark test and I am getting sub 200ms results so I believe the results you posted are definitely not that accurate to the individual panels.

You mention that 0.4ms input lag is huge, I definitely agree. I came from a Samsung SVA panel (144HZ) and I have to say, everything just seems way more SNAPPY (even at the same 120HZ). I am tracking targets (using VRB @120HZ) so well that my HS accuracy went up 2 folds!

For a real-world test, I loaded up CoD and picked a gun I never use so that I can see instantly how accurate I am. After 11 games, I am getting a headshot accuracy of 55%.

Keep in mind, my next best accuracy (with the gun I use the most) is only 24%. I'd say that is a major difference.

If anyone is curious, on CoD Warzone my headshot accuracy is 24% with an MP5 and 55% with an MP7. I believe this clear advantage has to do with how easy it is to track a moving target. The fluidity allows me to take shots that I normally do not take. And I felt this even when sniping with an HDR.

You mentioned earlier that G2G is more important than input lag and I have to disagree entirely. For gaming, input lag means everything. As long as the G2G is low enough that motion blur isn't noticeable, input lag should be the decisive factor in determining the best panel for gaming. I am willing to sacrifice 1ms of G2G if I have 0% overshoot. I do wish the Acer panels had better overdrive settings. The only option you can ever use is Normal.

In terms of quality, I believe the Acer Predator is much better especially compared to the ASUS 280HZ panel. My first panel (and the one I kept) has amazing black uniformity and imperceivable IPS glow in normal low-light conditions. I will make an update later for color accuracy.

I am curious about VRB however. I am stuck at 120HZ and it is impossible to go up to 144HZ. I was wondering if only the Nitro panel allows VRB @144HZ.

If anyone is in the know, please tell me why the Acer panels are so much better than the rest when it comes to input lag! TFT Central did a great review of the Acer Nitro XV273 and they believe it to have 0 signal processing. The only lag from the panel is simply the pixel response time element.

I also was wondering why you refer to them as Acer clones when the Nitro version has slightly lower input lag in your tests. I honestly believe that they all use the same panel. The 27" panel could just be slightly better actually. The Acer's just seem best for gaming. The colors on mine are actually quite good and I am picking up an X-Rite to calibrate mine. I did some DCI-P3 tests and I definitely see a difference so my panel is well above the sRGB spectrum. Now how close I can get to DCI-P3 will just be the icing on the cake.

I just have to say, guys, I LOVE this panel. I honestly have never seen such a drastic improvement in my gaming performance from any SINGLE upgrade. I have upgraded graphics cards, went from air to water cooling over a decade ago, replaced all fans with GT Typhoons (if noise had any impact on concentration lol), upgraded my mouse from a Zowie FK2 to an FM UL2, upgraded my headphones to the Audeze LCD-2C with a SMSL SU-8 DAC / THX 789 amp setup. And while each of those changes helped me slightly, nothing compares to upgrading to this panel. The advantage that I have in-game is just so perceivable, I am lost for words.

Hi, can you tell me wich settings are you using? What options did you put on or off? What calibration you are using?

I have the same monitor and it's incredible. It's WAY better than my previous 1440p XB271HU. But i dont find anywhere a calibration for it. I'm using it at factory default settings minus the sharpening effect that was on.

Sure no problem. For the factory calibration first of all, you'll want to make sure you are in sRGB mode. Keep black equalizer at 5 (do not ever change this). Gamma is 2.2. I run at 120HZ with VRB on, max brightness. Super Sharpness off always. Ultra Low Latency Mode always on. Adaptive Sync is off obviously. Can't remember if I am forgetting anything.

I have the AW2521hf and i send it back... the motion blur is soo bad, i dunno if the unit is bad or all the monitors are the same... but the ips cannot do real 240 hz on motion... please who has the acer xb3 to test if the monitor can keep 240 on the ufo motion test whith the pictures. The motion blur and the double image that the ips makes, is much worse than the tn i have at 144... so ips is still a generarion or a few years away from real 240 hz feeling. I dunno if there is somedoby here.that can see the differences and has a clue of how a 240 hz monitor should behave, but please if you have a tn240 and a ips 240, you will see a big difference in motion clarity from the tn and ips on my unit cannot keep 240 hz in motion... when i do a custom hz like 230 or lower, it can do smoother images... so please test for yourself.

Looks like the 240hz Samsung Odyssey G7 was made available for pre order on amazon.

HDR600
QLED technology
1000R curvature
VA
95% DCI-p3
240hz
1440p

the LG nano IPS or the viewsonic nano IPS from what i'm seeing is still superior at 1440p. Better HDR and better contrast ratios doesnt' make up the LIKELY very slow response times and lower gamut and inaccurate colors(VA colors and viewing angles aren't nearly as good as IPS). I'm guessing this will be around 9-10ms repsonse times as with most VA.

if you think about that logically, a monitor needs a 4.17ms response time to keep up at 240hz, anythign slower than 4.17ms, pixel smearing will occur. .no VA even comes close to 4.17ms pixel response times unless there's enormous overshoot. Then again, the samsung g7 may prove me wrong(but i seriously doubt it). My predictions are, 9ms-10ms response times w/ fast dissipating undershoot at 240hz.

based off the infererences i'm making, a lot of people will buy these monitors unfortunately. Especially ppl who don't know how how important a wide color gamut and pixel response times are.

also, there isn't any GPU that can get 240hz @ 1440p unless you play a budget video game like CS GO, Rocket league, etc. But when it comes to AAA titles? there's basically no chance. . Maybe the 3080ti with i9-10900k but you're looking at $2000+the motherboard. the 2080ti can't even break 144hz fps on some ps4 videogames at 1440p. I borrowed my cousine's 2080ti, and i would be lucky to get 144hz fps on any ps4 video game, but 240hz? not a chance unless you clamp to a lower resolution to non native(which will look blurry)

tld;r
in my opinion, the samsung oddyssey is dead on arrival.
