Sorry if there has already been a thread on this.

I am going to buy an lcd monitor very soon i will be doing mainly gaming watching movies and surfing the net.

I hear that its best to go for 2ms if your into gaming, 2ms monitor cost alittle more though, is 5ms considered good monitors? and is there much of a difference
 
There is very very little difference between 2ms and 5ms. Unless you will be playing at a pro level where you need every little teeny tiny thing to help you win, you really don't need to worry about response time.

Usually, a 6ms monitor is actually better than 2ms or 5ms monitor, because 6ms means either S-PVA or IPS panel, which both have better picture quality than the 2ms or 5ms TN panels.
 
Hey there,
at the end of the day we are talking miliseconds here. And looking at your setup, I wouldn't bother getting a very expensive monitor until the rest of my system as powerful as I wanted it to be. I'd go for a 5ms screen, you wouldn't notice the difference. Chris.

You'll probably want to shoot for a 6ms screen, given what it implies. They tend to be S-PVA/MVA panels, which most people qualify as superior to 2ms TN panels in a number of ways. You won't notice the difference in response times unless you're extremely sensitive, but you will almost definitely appreciate the superior viewing angles, black depth and colour accuracy.

No he doesn't want a S-PVA/MVA panel if hes gaming and doing any thing other than very casual gaming... they have a tendance to have levels of input latency that aren't acceptable for gaming.

2ms or 5ms doesn't make much odds as most 2ms panel use over-drive which can actually have worse results than 5ms unless you have an expensive 2ms panel.

The main problem for gaming tho (after input latency) is residual images and the difference in response time has little impact on that with current generation TFTs.

Actually in TNs there's huge measurable difference.
2ms TNs use RTC and their actual average response time is from little below 4ms to little above it while "5ms" TNs lacking RTC have actual response time of 13-15ms because without RTC other brightness changes than those between extreme states are slow. (smaller voltage affecting to liquid crystal makes it turn much slower even if required amount of turn is much smaller)
All better panels use RTC and their advertised value is quite precise (because they don't have to be advertised by lies in every spec) meaning they have less ghosting than most generic TNs.

So if anything it's 5ms TNs which should be kept as slow but as we don't have people complaining all the time about their ghosting we can conclude that nowadays response time makes very little difference. (and neither can be used for defending 2ms TN for gaming)

There are some with with very low input lag, like NEC 24WMGX3
http://www.tftcentral.co.uk/reviews/content/nec_24wmgx3.htm#gaming

Also IPS monitors (free of VA's horizontal gamma shift) can have very low lag.
http://www.tftcentral.co.uk/reviews/content/hazro_hz26wi.htm#gaming
Hazro just has fixed overbright backlight destroying black unless they've added circuitry required for that.
Harder to get LG W2600HP(-BF) has similar very low lag and actual brightness adjustment:

I have it and now consider IPS as only somekind successor for CRT after going from CRT through S-PVA to it.

And neither are all TNs automatically without lag but also they can have big lags depending what kind circuitry there's in signal path:

So rather good change that some TN owners who are bashing better panels for their input lag have also input lag not much better.


For difference between panel types here's comparison showing viewing angle dependancy of brightness/colour/contrast stability. In case of TNs there's not enough stability to have uniform brightness/colour across screen from bottom to top even when looking monitor directly from center of it.

(uniform colours can become colour slides shown in end of this page)
 
Its not much use looking at outright specs for speed, manufacturers figures are always skewed.

Only way to get a good idea is find a few models of TFTs that you fancy then look for comprehensive reviews on them. Input lag will be a factor for gaming too, not just screen refresh. I've seen some quoted 2ms screens that refresh worse than some 8ms ones.
 
I don't think there are many monitors with bad response times now. I don't know a lot about it but there are different ways of reporting reponse times. G2G (grey to grey) and B2B (black to black). B2B is better than that G2G.

example: "The BenQ M2400HD is capable of 1000:1 contrast, 300 cd/m2 of brightness and 2ms/5ms (G2G/B2B) ultra fast response rate"
