Average is a term used to hide exact data, to confuse novice people with rounded numbers. See all transition types, and get ur own conclusions. Some transitions need 11, 15, +20ms , crosstalk in TN is very unstable, from 1.2 to 20.5ms, hope XL2746S has fixed this and DyAc+ can make a good work.

100% GtG values in XV273X, with the same panel that Viewsonic XG270, varies from 3.5ms to 8.9ms, much more stable, and lower average also.
The newer TN panels have better refresh rates than the older Zowies and I expect the newer Zowies to follow that trend, though.

Acer Nitro XF252Q (TN):

-min: 0.9ms
-high: 5.8ms
-avg: 2.6ms

Acer Nitro XV273X (IPS):

-min: 2.4ms
-high: 9.1ms
-avg: 4.8ms


The gap has definitely closed between TN and IPS but the newest TN monitors are still faster than the newest IPS monitors. I'm curious to
see the test data on the new Zowie models.

About GtG percentages (for lag tests, versus ghosting tests, etc)

100% GtG values aren't necessary for lag tests. We already can see a pixel beginning at 10%. A pixel is mostly visible at 90%

A 50% transition (at usual gamma) means a pixel is already a relatively bright gray color, between black and white.

I usually prefer sites that lag-stopwatch GtG at about 10% or 50%. It's more relevant to human vision & human reaction time.

RTINGS ends their input-lag stopwatch at approximately GtG 2%, which I think is way too early, but it's very close to GtG 10% anyway, where most humans begin to see the pixels and begin their reaction-time clocks to them. Whereas TomsHardware often ended their lag stopwatch at GtG 100%. The different arbitrary GtG lag cutoff points as well as the different sync techs (VSYNC OFF vs VSYNC ON, and their differences in lag gradients along the screen's vertical axis), means input lag numbers are not possible to compare between different websites -- the stopwatch starts, the stopwatch ends, are all at different positions because of different measurement trigger / criteria, and different sensor locations, and different sync-tech settings.

For ghosting problems, yes, GtG 100% is an important metric. (Though GtG 98% or GtG 99% produces much more useful comparisions in ghosting-quality metrics than GtG 90% or GtG 100% -- it's very hard to translit GtG percentages to the afterimages of ghosting, but needless to say -- GtG doesn't need to be 100% yet in order for humans to begin reacting to stimuli like CS:GO enemies appearing -- they are noticeably visible at GtG 10% to GtG 50%).

When we make this type of ms comparations, we need to take in account % overshot deviation, and if both are compared in the same frequency.

If for example, one model get the extra speed with artifacts like inverse ghosting or halo, due to excesive Overdrive like Fastest or Ultra settings, and other model is free of these issues, with Overdrive at Normal setting, is not a fair comparation.

Rtings make a excellent work in GtG measure, with photo showing the full GtG curve and overshot, one for each OD setting, and now updated the XV273X response time section with also tables and more statistics. But only measure 240Hz and 60Hz. And there are a bug in the table i think, because shade 0-20 show 12ms, but the curve GTG for Normal Overdrive 0-20 show 8.9ms ¿?¿? :shock:

TFTCentral measure several more usefull frequencies, like 100 or 120 very interesting for strobe, there are the recommended in Viewsonic XG270 for low crosstalk. But TFTCentral unfortunately not show the GTG curve photo, so not know the %GTG transition that they show in the table.

Go to "Gaming Comparisons" table of PG27UQ review, this is the good way to compare TN Vs IPS, ms and overshot, hope they include also the different frequencies in future comparation tables, like a slider setting in table to select the frequency and comparte all monitors at 60Hz for example, and another slider for OD level, ok this is to much work... but is the only way i know to make seriously and fair comparisons.

https://www.tftcentral.co.uk/reviews/as ... htm#gaming

PG27UQ IPS 4-5-9ms -> Overshot free ! Green color
PG278Q TN 1-3-4ms -> but Overshot artifacts :( Orange color

If PG278Q with less overdrive, can run also overshot free, Ok get the new ms, and compare with PG27UQ again, maybe there are some surprise ;)

If compare Viewsonic XG270 with BenQ/Zowie XL2746S for example, is hard to know all these technical data of both monitors, we need more deeper reviews, extremely proffessional reviews.

As far as I can tell they did include that information for both monitors and the numbers I posted were the GtG results for when OTC error % was acceptable.
