Response times: how much do they matter?

Hi everyone, so I'm looking for a new 27" monitor to replace my 24". I've been digging around and found a BenQ on Amazon for $250. The only thing I'm worried about is that the response time is 12ms, 4ms GTG. How much will this impact gaming? I'm not well versed with displays so if you could provide a brief explanation I would be grateful.

This is the spec page for the monitor: http://www.benq.com/product/monitor/GW2750HM/specifications

Thanks everyone!

It really depends on the type of games you play and it is a very subjective thing. Unfortunately that means you're likely going to have to see for yourself.

The take-home message is that the responsiveness is massively improved compared to early AMVA panels and many people can happily game on this one. But there are some transitions that are troublesome and it wouldn't be a stretch to say some users wouldn't be satisfied.

Some of that thread is useful (particularly the 'don't pay too much attention to specified response times' bit) but statements like 'the human eye can't see anything less than 20ms' is frankly bo**cks. The average human reaction time is slightly higher than that for a reflex-reaction type response. That has nothing to do with what the eye and brain can process when it comes to visual stimulus.

It also starts off by talking about a monitor with a 12ms response time and no real active overdrive. One I happen to own and dislike for gaming. You can quite clearly see the difference between transitions on the BenQ where the overdrive is helping out (the 4-6ms ones) and ones where it isn't (12ms+).

Slow response time means the image gets blurry during high speed movement. So it can be quite noticeable in with fast paced games like first person shooters and race games though the effect gets more and more lost in modern games as they have motion blur effects of there own.

12ms is pretty slow for a modern panel and you will probably notice some amount of ghosting on it (VA panels are about the slowest around). Modern TN panels even regular 60Hz ones tend to sit in the 5ms or faster and even then some people still notice the slight blur. IPS panels have also come a long way in speed and there are many models that can do better then 10ms.

Thanks for the info. 120Hz monitors are out of my price range and they're honestly not my priority right now. How's this IPS monitor? It claims 7ms with overdrive but that's GTG, and the other monitor claimed 4ms GTG. So can you clarify that for me? Thanks.

Also, I'm looking for a monitor that has accurate color reproduction as I do some graphic design and photo editing & manipulation.

GTG (gray to gray) time has become more and more popular as it a lower number but it can be miss leading. The actual response time that is usually measured black-white-black is always higher. VA panels respond differently to black pixels so comparing a VA to a ISP or a TN based on GTG is a guessing game at best. This is why I hate when companies don't report the actual black-white-black number.

To put GTG response time in to perspective a TN panel with a response time of 5ms (some times called average response time and measured black-white-black) usually has an GTG (gray to gray) of only 1ms. You see how miss leading the GTG number can be and it should not be confused with actual response time. That being said a monitor with lower GTG will almost always be faster then a monitor with higher GTG.

That dell has a GTG of 7ms compared to the 4ms GTG so it is slower. Just don't buy a monitor with 4ms GTG thinking there will be no ghosting like on a fast TN panel with an actual response time of 5ms and a GTG of 1ms.

For graphic design and photo editing & manipulation response times are not really that big of an deal. Like I said earlier its more of an issue with fast paced games. So if you don't mind having some ghosting in games I would not be to hung up on response time.

If you want a glossy IPS get an Acer S275HL, it has the same ghosting issues as the Dell but the overdrive can be deactivated in the service menu and it is less reflective. Read this for more info about all of the 27" 1080p IPS:

Thanks, the only problem with the Acer is that it is not VESA mountable, so it's out of the running for me. Do you have any other suggestions? Thanks again.
