    Response time on a monitor

    How do i tell which is which? Cause they list most monitors as 5ms but i was told it can be grey to grey not white to black is not very good for games. How do you tell which kind of response the ms is?

    They usually specify, if they don't any decent review will.

    Re: Response time on a monitor

    Is 8 ms G2G too low for games i dont really understand the difference. I was looking at Dell Ultrasharp LED IPS 23" Monitor U2312HM and
    this LG IPS234V IPS LED 23 12 ms not sure whether thats G2G. Im just wondering whether ill notice a difference in games compared to my current FLatron.

    I was just about to buy one of those and one of my friends told me it has bad response time for playing games but i didnt really understand what he meant.

    Re: Response time on a monitor

    TBH,the response time of many modern monitors is more than enough. The U2312HM and IPS234V both have overdrive AFAIK,although the Dell is meant to be more aggressive in this case. Here is a review of the LG:

    It depends whether you are a measurebator or not.

    Re: Response time on a monitor

    Thanks i dont care massively what it is as long as i dont have any very noticable response lag. I think ill go for the Dell im not sure im sold on the stand for the LG. What does overdrive mean?

    Re: Response time on a monitor

    The manufacture listed response times are rarely a good representation of what you'll actually get, most only state the G2G speeds (and how often do you play back & white games?). Plus that only concerns the screens responsiveness, you also need to consider the input responsiveness (which can vary quite a bit).
    This website: http://www.prad.de/en/monitore/reviews.html does very very through testing and reviews of monitors.

    I looked at the Dell suggested by CAT, its a great monitor, but I plugged for the Asus PA23Q, costs a little more but its worth it IMO.

    Re: Response time on a monitor

    I ended up getting the LG initiall suggested by CAT its pretty cheap and its not like i need top of the line. And at this price i can always get another one later if there is anything exceptional. Thanks , Can you tell me more about Overdrive?

    If you care about how fast your video card draws frames then you probably also care how fast your monitor draws frames.

    Re: Response time on a monitor

    Samwood is right - input lag is just as important as response time.

    Response time - the time taken for the pixel on screen to change from one state to another (and back again)
    Input lag - how long between the signal from the PC is actually displayed (compared to, say, a CRT monitor). You can have the world's best response time, but if your input lag is too high you'll be dead before you realise you've spawned.

    Re: Response time on a monitor

    And bear in mind that when compared to human response time it's peanuts: take the test here and see if 5, 8 or 10 milliseconds for your hardware is going to make much difference!

    Re: Response time on a monitor

    but while that may be so Jake, the cumulative effect of things not quite changing quick enough is discernible as ghosting, smudging and blurring. My monitor occasionally, very occasionally in HDR games isn't quite quick enough to not leave some smudge after flash-bangs due to the pixel response not quite cutting the mustard - and mine is a good monitor as IPS goes (or went - it's two generations old now).


    www.tftcentral.co.uk is another good site that gives very in depth reviews (of IPS screens - not TN (though tbh why would you bother now that IPS has dropped in price)) and explains the subtleties of all this.

    Re: Response time on a monitor

    Your eye can discern 60Hz - 60 changes per second correlating to a 16.7ms response time (see edit below). My understanding is that this affects things thus:

    Input LAG:
    It's why reviews state input lag over 15ms puts you 1-2 frames disadvantage. Add to that human response time - as Jake points out - and you really are behind (and probably already waiting to respawn (again))

    Response time:
    Now if grey-to-grey response time is stated as 10ms, what do you reckon the black-white-black response time is? Larger? Sfaik probably. So if you're in a dark shadowed corridor and a flash/strobe occurs you will see ghosting of the flash after it has ended - discernable to the eye - as the pixels catch-up. This is nothing to do with human reaction time in responding to it and is purely about what you can actually see with your eyes.

    Edit: Yes, I know 60Hz screens generall don't flicker but there's more going on. Taken from wiki (which in turn cites far better references):
    "The human eye and its brain interface, the human visual system, can process 10 to 12 separate images per second, perceiving them individually,[1] but the threshold of perception is more complex, with different stimuli having different thresholds: the average shortest noticeable dark period, such as the flicker of a cathode ray tube monitor or fluorescent lamp, is 16 milliseconds,[2]"

    Cat already provided the link to what overdrive is:

    You don't need to use it in most cases - the monitor will apply it automatically or while in gamer mode.
