Click his link... it's in German.

In dieser Untersuchung zeigt der Acer GD245HQbid eine Verzögerungszeit von 18,2 Millisekunden. Hinzu kommt noch die halbe mittlere Bildaufbauzeit von 3,1 Millisekunden. Die mittlere Gesamtlatenz beträgt somit 21,3 Millisekunden – ein hoher Wert für aktuelle Geräte, vor allem für einen Gamer-Monitor. Offenkundig speichert dieser Monitor immer einen Frame zwischen. Dies ist auch bei 120 Hz zu beobachten, hier beträgt die mittlere Gesamtlatenz wegen der halbierten Framezeit nur noch 12,9 ms.

Translation:
This study shows the Acer GD245HQ has a delay time of 18.2 milliseconds. Added to half the average screen time is 3.1 milliseconds. The mean total latency is therefore 21.3 milliseconds - a high value for a current device, especially for a gamer monitor. Obviously, this monitor always has a frame between. This is also observed at 120 Hz, where the average total latency is halved because of the ms time frame, only 12.9.

I got 120hz just for 3D support

Sorry, I see it:

The Acer GD245HQbid wants to be a pure player and monitor, in fact, is a very fast GD245HQbid monitor, in terms of reaction time. The input lag is 21.3 ms (60 Hz) and 12.9 ms (120 Hz) mediocre, if not even notice this in operation. The 3D performance is convincing, even if the maximum brightness will be higher. In terms of interpolation, the monitor shows no weaknesses.

So it's actually 12.9ms at 120Hz, but I didn't see any mention of Overdrive being disabled. So we can assume it's even less.

I just ordered a XL2420T a couple of hours ago, I guess it'll arrive on Monday, perhaps Tuesday wink.gif
Can't wait wheee.gif

Would of have bought the TX-version, but it's not available in Europe jealoussmiley.gif

I wouldn't worry about it either way. If you don't notice it that's all that matters unless you're seeking e-peen. If the latter is true then the BenQ holds the title for input lag according to reviews (5-6ms).

I know about the BenQ, but I had to save a little bit of money. stitchfacesmiley.png

The Acer sure is not 18ms, that's all. That is something like crappy 1994 wireless mouse lag.

A lot of the 2ms and 5ms times are marketing fluff and not averages. There are certainly times where modern panels may have higher numbers like that.

I'm pretty sure that's been proven false numerous times.
http://www.100fps.com/how_many_frames_can_humans_see.htm - Example 1
http://whisper.ausgamers.com/wiki/index.php/How_many_FPS_human_eye_can_see - Example 2

LOL 18 FPS is fluid to the eyes? Track panning motion at 24 FPS on any display and then tell me that it's enough for motion to be fluid. It only works on film projectors which shutter the image AT 24 Hz. BUT, there is visible light flicker at 24 Hz. So they moved to a 48 Hz shutter; Each image flashed twice. Track that with your eyes, it jitters. The only solution to do away with any kind of crappy motion artifacts is to up the refresh rate of the image. Even if a panel can't fully keep up, it still makes a difference over 60 Hz. If movies were even shot in 60 Hz they would be totally awesome. Also, motion blur is required to make slow images appear more fluid. Ever watch a movie with a really fast shutter (minimal motion blur)? It's disgusting.

There is NO problem with peak-and-hold displays. The problem is that outside of TV, there is cinema, and they refuse to adapt to the times. They just keep pushing for 2k, 4k, and 3d. Oh great, I can watch a 24 FPS atrocity at 4k resolution in 3d rolleyes.gif People also refuse to realize that there are still 4 dimensions; time affects resolution. An average consumer would be absolutely stumped if you showed them a 720p60 movie and a 1080p24 movie. They would prefer the 720p60 movie until they were told that it was only 720p, and then their instinct that likes big numbers would kick in. Motion blur destroys resolution. Compressing gradients is tough. Compressing video without blur would be really easy. We wouldn't need any more storage than what is available today. We can just pack stupid extras on other discs or other sides.

We need to adapt and develop a real 120 Hz interface now so they can base LED TVs around it. A 1080p120 image will be much better than 4k@24.

Not to mention anything more than 1440p is a waste for 99% of home setups.

And another thing I forgot to mention is that the higher resolution we go, the closer we have to sit for a fixed size screen or the larger the screen has to be for a fixed viewing distance. The larger the picture the more physical distance there is between moving frames.
