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

[goa604]

it's definitely a gamechanger but your brain has to get used to the input lag penalty. Me personally, i never had to because i don't use a mouse and keyboard to play, i use a ps4 controller wired. All i have to do is play it on bluetooth and the input lag is basically mitigated.

That doesnt make slightest sense.

[RLCSContender*]

On bluetooth, the input lag on the ps4 controller drops from 10ms(wired) to 2ms(bluetooth). Dont ask me, that is how sony designed it.

Problem with bluetooth is if there is interference, it can fluctuate from 2 ms to 25 ms

Has anyone done a 240hz tn tier list?

[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.

I play with PS4 controller on PC as well. I over clocked my wired PS4 controller to lower input lag. Here is the video I used.

Any experience with VG252QXBMIIPX or XV253QXBMIIPRZX? They seem pretty cheap in my country. MAG is like 100 euro more in comparison.

i always assumed MPRT only factored in when you are strobing because "1ms" MPRT so i thought that was a measurement exclusively to backlight strobing.

Correct. MPRT is a measurement standard, not a strobe setting.

MPRT applies to all displays, strobed or not.

Some chinese scaler vendors/TCON make mistake that "MPRT" is a strobe backlight, but that's a miscommunication simply because low MPRTs are only possible with strobing today, because we can't do unobtainium refresh rates yet.

MPRT is bottlenecked by refresh duration for sample-hold. 1/120sec = Guaranteed no less than 8.3ms MPRT(100%) average for a classical sample-and-hold display (OLED, LCD, or any tech that constantly illuminate a pixel for a whole refresh cycle)

For readers still confused, see Pixel Response FAQ: GtG versus MPRT.

How are response times on AW2521HF on 100-144hz? With freesync and extreme overdrive?

[RLCSContender*]

don't even bother with extreme overdrive and super-fast on the alienware aw2521hf. The ghosting is horrendous. from my recollection it was around 25% inverse ghosting error on super-fast and 60% inverse ghosting error on extreme

and by request, i will post MY rise/fall times on those refresh rates tonight. yes, i used my $500 digital/lab oscilloscope which in my opinion is very accurate.

The aw251hf is still slower than the MSI MAG251rx if "fast" overdrive i used on the AW. However, if "super-fast" is used at 240hz, it's faster than the MSI MAG251rx, but the overshoot is 10-12%(it jumps from 25% to 10-12% due to the unique displayport scaler on the alienware monitor, this probably explains why it's freesync certified AND g-sync compatible certified). I'm surprised Rtings missed that critical detail on their review of the 25" alienware. Then again, they aren't allowed to void warrantee, but I opened up the thing and yes, it has a unique scaler on DP.

tld;r

3.4ms g2g if "fast" OD is used at 240hz for th ealienware
3.1ms g2g if "faster" OD is used on the 240hz MSI

however

2.6ms g2g if "super fast" OD is used on the 25" alienware 240hz ips. Sadly, the overshoot is mitigated but very distracting "glow" occur from time to time. What you will see aren't artefacts but a blue glow from time to time. The good news is, no inverse ghosting artefacts that i've seen. When i played rocket league on super-fast, the blue glow sort of helped me out when i hit the ball but when i played other games, the glow was just TOO distracting. I suggest you leave the OD to "fast" on the alienware.

the problem with "fast" OD is 1% inverse ghosting error. There' nothing wrong with that but it could've benefitted more if it had slightly more overshoot(around 5-8%) and but a faster response. unfortunately, the peak performance isn't up to par with the MSI if they playe it too safe on the overshoot errors. . The MSI for example has 3.0ms or 3.1ms g2g average and has a 6% overshoot error which is basically non existent when i played video games with it.

Is the VG259qm the same as the bigger one or is it in any way worse? It's significantly cheaper than the other 240 Hz IPS monitors in China, and I can't see MAG251RX anywhere locally
