I believe that 0 would be impossible for any monitor because the lag is also dependent on other hardware in your pc.

Yes, that is very true. As long as my monitor is the lowest input lag among most 120hz monitor i'm happy.

The BenQ has the lowest input lag as far as I know. I switched from a CRT to the BenQ and can't feel any input lag. Whether you feel the input lag or not depends also on your refresh rate. If you are running 120hz you wouldn't feel anything lower than 8.3ms. If you are running 60hz you wouldn't feel anything lower than 16.7ms.

BenQ XL2410t has 5ms of input lag. Asus VG236H and Alienware AW2310 have 13ms. I've used both the BenQ and Alienware and I did not feel a difference even though there is a 8ms difference and I'm usually very sensitive to things like that. This was while playing CoD:BO and CSS. There may have been a very very very slight difference when vsync was enabled (since that still causes slight input lag as well, even at 120hz).

If you're thinking about the Alienware, you should know that its response time acceleration is only on when using the gaming or multimedia color presets. That means you won't get as good of colors and gamma as if you used the custom rgb preset. If you don't use those two presets, the response time is low and looks a little blurry.

Link to review showing 5ms average please.

This is the only review I could find showing less than 8ms average:

The responsiveness of a monitor is not only affected by the pixel transition times (response time), but also by the internal processing done by the monitor itself before the image is displayed. This delay between the graphics processor outputting data and the monitor displaying it is often referred to by the all-encompassing term ‘input lag’. It is possible to get a rough idea of the level of input lag of an LCD monitor by following a methodology such as this one. This involves using a camera at high shutter speed to measure the number of ‘frames apart’ that an LCD monitor and CRT monitor are, in a ‘clone mode’ setup, at a given point in time. Working on the assumption that a CRT exhibits negligible input lag, it is possible to work out the input lag of the LCD monitor relative to the CRT monitor. Some simple mathematics tells us that at a 120Hz refresh rate and under optimal conditions the XL2410T will display one frame 8.33ms after the other (1/120 = 0.0083s).

By following a similar methodology to the one outlined by Lagom, but using a modified counter and a splitter cable, it is possible to measure the input lag of the XL2410T in terms of ‘frames behind’ our high-end reference CRT. Because there is no way of accurately measuring fractions of frames you must rely on best judgement to work out the nearest whole-frame value that is displayed if the camera catches the LCD on the transition between frames – hence you are limited to an accuracy of 8.33ms for each reading. If the frame difference between both monitors is ‘2 frames’ at a given point, for example, the input lag would be recorded as 16.66ms (2×8.33 = 16.66).

By repeating this measurement 30 times we were able to gauge a rough but representative value for the average input lag on the BenQ XL2410T of 9.16ms. BenQ also includes an ‘instant mode’ which bypasses some of the internal processing done by the XL2410T and hence reduce input lag. According to our measurements it succeeded in doing this, lowering the already exceptional input lag to an average of 6.76ms. Both of these readings are limited by the inaccuracies outlined above but they are both very low values indeed for an LCD monitor. Needless to say the XL2410T was a brilliantly responsive monitor in our ‘real world’ testing with imperceptible levels of input lag. Even the most demanding gamers are likely to appreciate the responsiveness on offer here from BenQ.

I don't argue that the BenQ has the lowest input lag. But I haven't seen anything which states it is has been tested to be 5ms on average.

Note that I say on average, because no lcd monitor consistantly has the same input lag. Input lag is measured as an average. Sometimes it's higher, sometimes it's lower (on the exact same monitor).

http://www.tftcentral.co.uk/reviews/benq_xl2410t.htm says 5.6
http://www.flatpanelshd.com/review.php?subaction=showfull&id=1291718728 says 0 which is most likely inaccurate

So when I talk about the BenQ I just say 5.

They mean 0 frames not 0 ms

I wish there were some more views of the Planar up to confirm that the input lag is 10ms.
