philips 200w6 response time

I am just wondering whether someone knows the response time of the 20'' Philips 200w6 monitor. According to the magazine ‘pc pro’ it is 16ms whereas a seller on the Internet says 8ms.

    Everything I see says 16ms and in agreement with Philips. The seller appears misinformed.

    Philips says 8ms, so I'd say it's 8ms.

    This may be a case of two different sources saying the same thing in two different ways.   Think of a sine wave -- if you measure the peak-to-peak time you'll get one measurement; if you measure peak-to-valley you'll get half of that.   The spec you quoted above says it can turn on or off in 8ms;  so it will take 2 x 8ms = 16ms to turn on AND off.    I don't know if that's why the magazine said 16ms or not, but it would explain the difference.

    peak-to-peak => 2Pi => on,off,on => 24ms

    peak-to-valley => Pi => on,off => 8ms

    just a thought though ...

    The problem is that pc pro states 8ms for the acer al2032wa. shall i half this time then as well ?  ....

    Note your math:  2Pi = 2 x Pi ==> the number is double, not triple

    But no, I doubt you'd half the time for the acer.   I suspect the difference is not really anything so subtle; it's just a case of misquoting the specifications.   I'd go with the Philips specs, as most magazine reviews simply quote the literature anyway;  they rarely (if ever these days) actually have the test equipment to measure the actual response.
