  Probably uses the same 25" 240hz panel used in the Gigabyte KD25F. Hardware Unboxed's tests generally revealed that .5ms GtG was likely only a figure for best-case scenarios under the fastest overdrive mode (ie: introduces overshoot artifacts), and that under the optimal overdrive setting and across a range of different transitions, it's not really .5ms GtG. That being said, this panel is the fastest on the market, so regardless of the monitor-maker, if your goal is competitive PC games, then this new wave of 25" 240hz TN panels are the monitors to get.

  I'm not sure what "3 ms native response time" means but GtG response time is a giant steaming pile of marketing if there ever was one. Imagine if someone ever told you your car can accelerate from one speed to another in less than 1.4s. But it accelerates natively in 4.1s.
  
  It's a stupid and deceiving metric and one should NEVER take it at face value until someone actually measures and confirms what it means according to an agreed standard (like BtB). The monitor equivalent of 0-100-0Km/h.
  
  And any self respecting tech journalist should call them out on this BS every time and say clearly that the particular measurement says nothing about actual monitor performance.

  If they were that honest, they would also add the input lag to their product description. But they dont.
  There are several monitors out there that achieve sub-1 ms input lag, have been since at least 2012.
  Yet you still see "gaming"monitors with input lag FAR FAR above that. 20 times as much is not rare. And yet reviewers still call an input lag of 5 to 15 ms good.

  It is similar to the static vs dynamic contrast ratio. Static contrast ratio is the true contrast ratio, the dynamic one is ... whatever each marketing team wants it to be. The GtG response time apparently is about the luminosity response rate - the time it takes each pixel to switch from one shade of grey to another, or from a brighter/darker color X to darker/brighter color X.
  
  Probably not the luminosity range from full black to full white, but from a certain dark shade of grey to a certain light shade of grey, which are of course whatever each manufacturer wants. So that's equivalent to the dynamic contrast ratio. It is practically useless, because it could only be accurately measured with a special "temporal photometer" or some similar device when the monitor was in black & white mode (so that the colors don't get in the way) and after the lowest and highest parts of the luminosity (darkest and brightest respectively) were clipped out.
  
  "Native response time", in contrast, should take into account both the full luminosity range of the panel *and* the full color range (and color change rate) of the panel. I have no idea if the "3 ms" number they gave is valid, but assuming it is, it's the only useful response rate number of the panel, since this is what our eyes can see. 3 ms is a number 7.5 times larger than 0.4 ms. 3 ms might just be the true response rate, but 0.4 ms sounds much sexier, which is why I am quite certain Acer will bury that 3 ms number deep in the monitor's specs...

  The gtg is most likely to be a transition from dark grey to black. But on these new monitors it is most likely just a lie. A recent acer monitor advertized as 0.3ms gtg was measured by tft central and found to have 0.9ms as the best out of 30 possible transitions measured.
  
  The average reality is that these new sub ms monitors are about 25% better in terms of motion clarity vs yesterdays 240hz. Once again the advertizing is basically a lie.

  Is this a joke right? No wonder no one is investing in better panels when they keep making this crap.. what incentive do they have..lol

  You know of a faster panel? Not everybody cares about resolution or color gamut. There's a monitor for every market, if you're not the target demographic go look somewhere else. Seriously. You don't see me bitching every time they release a professional panel that has terrible response time - it's not aimed at me.

  1000% agree with last few folks, was going to say pretty similar.
  
  Peddle all the crap you want, but when you see it not being sold or folks end up complaining
  
  "Y'all have yourselves to blame"
  
  We already have to deal with plenty enough marketing BS spins "to make the sale"
  
  be different, and list actual response time (true input lag best case type thing)
  
  Not convoluted metrics "everyone else is doing it, so it must be good enough"
  
  No, no it is NOT good enough, response time, input lag, total shift between contrast / flicker and all that lovely stuff, at least have readily available free of charge.
  
  There is also the flat title of 240Hz long arse number instead of 1080p / 240Hz HDMI v2+ / DP 1.3+ / DVI / (other ports as on the product in question)
  
  many consumers are not "idiots" but treating them like they are, or not error checking instruction manuals is making the companies in question "fools and liars"
  
  we deserve better than such treatment.

  > Color Gamut: sRGB (?)
  
  They probably just said that by itself because 72% NTSC is about 100% sRGB
